Quick PrintAnnex A Explanatory Material
Annex A is not a part of the requirements of this NFPA document but is included for informational purposes only. This annexcontains explanatory material, numbered to correspond with the applicable text paragraphs.
A.1.1
The primary semiconductor and related industries include, but are not limited to, the following:
(1) Silicon Integrated Circuits. Traditional semiconductor process for memory, logic, microprocessors, and similar integratedcircuits on silicon wafers. Process includes epitaxial layer formation, oxidation, chemical vapor deposition, sputtering,photolithography, etching, and ion implantation. Processing can involve the use of over 30 electronic specialty materials—primarily in gas and liquid form. Current technologies focus on 7.9 in. (200 mm) and 11.8 in. (300 mm) wafer sizes while 17.7in. (450 mm) wafer technology is under development.
(2) III–V MOCVD (Metalorganic Chemical Vapour Deposition). Process using the III–V family of semiconductors for powertransistors, logic chips, LED, and some photovoltaic products on typically gallium arsenide wafers. Process is similar to siliconwafers, but primary materials are different and/or used in different quantities (processes require large volumes of arsine,phosphine, ammonia, and metal organics). Current technologies focus on 5.9 in. (150 mm) wafers.
(3) TFT-LCD (Thin film transistor liquid crystal displays). Process utilizing large glass substrates to manufacture flat-panel displaysfor use in televisions, computer screens, mobile device screens, and other applications. Primary process includes PECVD(plasma-enhanced chemical vapor deposition), photolithography, sputtering, and etching (dry and wet). The number ofhazardous materials used is less than silicon processes, but the volumes are much larger; usually involving bulk supplies. Thelatest Generation 8 process utilizes 86.6 in. (2200 mm) x 98.4 in. (2500 mm) glass substrates.
(4) Crystalline Silicon Photovoltaic. Silicon-based process for creating solar cells on wafers, square ingots, or ribbons. Processdoes not require stringent cleanliness, and is located in nonclean room environments for doping silicon layers and growingantireflection layers. The use of PECVD process is prevalent, with new ion implantation technology introduced in 2011.
(5) Thin Film Photovoltaic. This industry is much more fragmented with many different types of technologies on a variety ofsubstrates (glass, stainless steel, silicon ribbon). The traditional amorphous silicon process uses silane, ammonia, nitrogentrifluoride, and trimethylboron mixtures in bulk supply. Other technologies use different materials and techniques.

A.3.2.1 Approved.
The National Fire Protection Association does not approve, inspect, or certify any installations, procedures, equipment, or materials;nor does it approve or evaluate testing laboratories. In determining the acceptability of installations, procedures, equipment, ormaterials, the authority having jurisdiction may base acceptance on compliance with NFPA or other appropriate standards. In theabsence of such standards, said authority may require evidence of proper installation, procedure, or use. The authority havingjurisdiction may also refer to the listings or labeling practices of an organization that is concerned with product evaluations and isthus in a position to determine compliance with appropriate standards for the current production of listed items.
A.3.2.2 Authority Having Jurisdiction (AHJ).
The phrase “authority having jurisdiction,” or its acronym AHJ, is used in NFPA documents in a broad manner, since jurisdictionsand approval agencies vary, as do their responsibilities. Where public safety is primary, the authority having jurisdiction may be afederal, state, local, or other regional department or individual such as a fire chief; fire marshal; chief of a fire prevention bureau,labor department, or health department; building official; electrical inspector; or others having statutory authority. For insurancepurposes, an insurance inspection department, rating bureau, or other insurance company representative may be the authorityhaving jurisdiction. In many circ*mstances, the property owner or his or her designated agent assumes the role of the authorityhaving jurisdiction; at government installations, the commanding officer or departmental official may be the authority havingjurisdiction.
A.3.2.3 Listed.
The means for identifying listed equipment may vary for each organization concerned with product evaluation; some organizationsdo not recognize equipment as listed unless it is also labeled. The authority having jurisdiction should utilize the system employedby the listing organization to identify a listed product.

A.3.3.6 Corrosive Material.
A chemical is considered to be corrosive if, when tested on the intact skin of albino rabbits by the method described in Appendix Aof 49 CFR 173, it destroys or changes irreversibly the structure of the tissue at the site of contact following an exposure period of 4hours. This term does not refer to action on inanimate surfaces it destroys or irreversibly changes the structure of the tissue at thesite of contact within a specified period of time using one of the in vivo or in vitro OECD test methods authorized in 49 CFR Part173.137. For purposes of this code, this term does not refer to action on inanimate surfaces (e.g. steel or aluminum). Availabletesting data produced prior to September 30, 1995 from the test method in Appendix A to 49 CFR Part 173 in effect on October 1,1994 can also be used to determine the corrosivity of a material . [1,2012 2015 ]
A.3.3.22.1 Permissible Exposure Limit (PEL).
The maximum permitted time-weighted average exposures to be utilized are those published in 29 CFR 1910.1000, “AirContaminants.” . [5000,2009 2015 ]
A.3.3.38 Toxic Material.
While categorization is basically simple in application, the degree of hazard depends on many variables that should be carefullyconsidered individually and in combination. Some examples include the following:
(1) Materials wherein the toxic component or mixtures thereof are inextricably bound and cannot be released so there is little or nopotential for exposure.
(2) Nonfriable solid hazardous materials existing in product forms and in the demonstrated absence of inhalable particles thatmight not present the same inhalation hazard as the chemical components existing in a friable state.
(3) Mixtures of toxic materials with ordinary materials, such as water, that might not warrant classification as toxic. Any hazardevaluation that is required for the precise categorization of toxic material is required to be performed by experienced,technically competent persons. [1, 2012]
A.3.3.38.1 Highly Toxic Material.
In application, the degree of hazard depends on many variables that should be carefully considered individually and in combination.Some examples include the following:
(1) Materials wherein the highly toxic component or mixtures thereof are inextricably bound and cannot be released so there islittle or no potential for exposure.
(2) Nonfriable solid hazardous materials existing in product forms and in the demonstrated absence of inhalable particles thatmight not present the same inhalation hazard as the chemical components existing in a friable state.
(3) Mixtures of highly toxic materials with ordinary materials, such as water, that might not warrant classification as highly toxic.Any hazard evaluation that is required for the precise categorization of highly toxic material is required to be performed byexperienced, technically competent persons. [1, 2012]
A.3.3.39 Water-Reactive Material
There are three classes of water-based material. Class 1 water-reactive materials are those whose heat of mixing is at or above 30cal/g and less than 100 cal/g. Class 2 water-reactive materials are those whose heat of mixing is at or above 100 cal/g and lessthan 600 cal/g. And Class 3 water-reactive materials are those whose heat of mixing is greater or equal to 600 cal/g.
A.3.3.40 Workstation.
The terms workstation, tool, process tool, process equipment, and semiconductor manufacturing equipment are often usedinterchangeably. In the U.S., the term workstation has connotation and definition under other recognized codes and standards. Inthis document, the term workstation is used to specifically designate the point where a single process step, function, or procedure isperformed. Equipment used in the manufacture of semiconductor devices can contain one or more process steps and accordinglyone or more workstations.
It should be noted that all workstations are tools, but not all tools are workstations.
The workstation can include connected cabinets and contain ventilation equipment, fire protection devices, sensors for gas andother hazards, electrical devices, and other processing and scientific equipment.

NFPA 55, Compressed Gases and Cryogenic Fluids Code, is a material-specific code that addresses the storage, transfer, and useof industrial gases. The requirements within NFPA 55 are applicable for semiconductor and related facilities. The NFPA 318standard leverages the requirements within NFPA 55 by referencing relevant chapters. Within Chapter 7, NFPA 318 providesadditional use and industry-specific gas-related requirements pertaining to semiconductor and related facilities.
The use and industry-related requirements in NFPA 318 were developed by comparing the following primary gas-specificsafeguards contained within NFPA 55 and NFPA 318:
(1) Gas detection systems and source shutdown arrangements
(2) Restricted Flow Orifices (RFOs)
(3) Emergency shutoff valves
(4) Pressure relief devices for sources
(5) Ventilation rates for various arrangements
(6) Fire detection and fire protection for various arrangements

A.7.1.4.1
Automated purge panels are recommended because they reduce the potential for human error. [See 7.6.2 for silane and silanemixes.]
A.7.1.4.3
The basic components of purge panels should incorporate the following features:
(1) Tied diaphragm regulators should be used.
(2) All piping or tubing connections, except the valve connection to a cylinder, should be welded or have a metal gasket face sealfitting with zero clearance.
(3) Burst pressure components should be rated to at least 50 percent above the maximum pressure available to all components.
(4) All components should have a helium leak rate no greater than 0.00001 cc/hr.
(5) Regulators should be of the hand-loaded type. Dome-loaded regulators should not be used on hazardous gases. Remotelyoperated gas-delivery systems can use dome-loaded regulators.
(6) No check valves should be used as a primary control of potential cross-contamination and backflow.
(7) Electrical components on purge panels should be intrinsically safe.
(8) Excess flow control (valve or switch) should be provided on the high-pressure side of the purge panel.
(9) Emergency high-pressure shutoff valves should be provided and should operate on the activation of an emergency off button,gas monitoring alarm (high alarm), or electronically monitored excess flow control switch.
(10) All systems should be equipped with an emergency shutoff.
A.7.1.6

Alternative substances should be considered for replacement of hazardous gases.
A.7.1.9.2
The use of normally closed, pneumatic-operated cylinder valves located directly on HPM cylinders is preferred as it provides theability to isolate the cylinder and stop gas flow in the event of a leak. Emergency shutoff valves located downstream or adjacent tothe active cylinder might not be effective in preventing leaks caused at the point of connection of the cylinder to the gas deliverysystem, where the majority of leaks are involved.

If an RFO is placed in a system with an excess flow device, the excess flow device might not shut off.
A.7.6
CGA-13 contains extensive requirements for the storage, use, and handling of silane gas. With some exceptions, theserequirements are aligned with the historical approach within NFPA 318. Exceptions are included within NFPA 318 requirements invarious sections.
The use of silane/toxic mixes is discouraged because of the dangers inherent in these materials. Alternative methods should besought to eliminate the use of these chemicals. Due to the extremely hazardous nature of silane, storage and dispensing areaswould benefit from video cameras for remote monitoring and security purposes.
A.7.6.1
The use of a cylinder-mounted automatic pneumatic cylinder valve is the preferred shutoff valve. Pneumatic valves that employ aknife edge seat design reduce cross-port leaks and silane “poppers.”
A.7.6.2
The use of two single-stage regulators in series will help reduce liquefaction during pressure reduction. Replaceable metal gasketsin DISS connections are preferred over PTFE gaskets that can cold flow and leak at pressures higher than 500 psi. The use of solidstainless steel pigtail lines is preferred over flexible steel lines. The use of a venture eductor to evacuate the gas panel duringsystem purge is strongly recommended. The dome of the pressure regulator should also be vented to a safe location.
A.7.14.2
A subatmospheric gas source (SAGS) reduces the risk and magnitude of gas releases. In a SAGS, a vacuum (subatmospheric)condition is required to induce gas flow from the cylinder. An accidental opening of the valve under atmospheric conditions willresult in little or no gas release. In a Type 1 SAGS, gas is adsorbed on a medium and is released under a vacuum condition. In aType 2 SAGS, the pressure driver is mitigated via a normally closed internal valve that requires a vacuum condition to release thegas. Because of its improved built-in safety features, a SAGS should be used instead of standard high-pressure cylinder gaswherever process compatibility allows.
A.7.14.2.1
Release rates from SAGS will be small relative to a conventional compressed gas. When combined with ventilation, this results in alow risk of mixing incompatible gases.
A.7.14.2.2
Subsections 9.1.4 and 9.1.5 provide reference requirements in NFPA 1, Fire Code, for minimum external face velocities of 200 fpm(1 m/s) at openings. Maintaining conditions below IDLH within the gas box represents a higher standard of control. Also, per NFPA1, treatment systems for corrosive, toxic, or highly toxic gases can include nontreated ventilation systems that dilute the accidentalrelease to less than 1/2IDHL. Ventilation system design for SAGS meets these dilution thresholds and therefore meets therequirement for treatment systems.
A.7.14.2.5
The automatic shutoff valve requirement is effectively met in both SAGS sources. SAGS sources are designed to flow gas undervacuum conditions and, coupled with ventilation requirements, ensure that concentrations in gas cabinets or exhausted enclosureswill be less than IDLH.
A.7.14.2.6
A Type 1 SAGS has an inherent flow restriction because the cylinder’s internal gas pressure is subatmospheric.

A.8.2.1.2
NFPA has developed NFPA 287, Standard Test Methods for Measurement of Flammability of Materials in Cleanrooms Using a FirePropagation Apparatus (FPA), to provide guidance for the assessment of the fire hazard expected of materials used inenvironments highly sensitive to thermal and nonthermal damage, such as within cleanrooms in the semiconductor industry. ASTMhas also developed ASTM E 2058, Standard Test Methods for Measurement of Synthetic Polymer Material Flammability Using aFire Propagation Apparatus (FPA), as a generic version of the same test method. The initial work on this issue was performed atFM Global and published as FM 4910, Clean Room Materials Flammability Test Protocol.
The protocol utilizes three small-scale tests. The small-scale tests are performed in a flammability apparatus that includes a fireproducts collector and data evaluation equipment.
The tests are as follows:
(1) Ignition tests
(2) Fire propagation tests
(3) Combustion tests
Based on results of the three small-scale tests, the following indexes are determined for each material tested:
(1) Fire Propagation Index (FPI). This index is determined based on the fire propagation tests conducted and represents theease/difficulty of fire propagation on the surface of the material beyond the ignition zone, under simulated flame heatingconditions expected in large-scale fires. Nonpropagating materials have FPI values at or below 6.0.
(2) Smoke Development Index (SDI). This index is defined as the product of the FPI index and the yield of smoke for a givenmaterial and represents the rate at which smoke is expected to be released during fire propagation. Materials expected torestrict smoke development have an SDI of 0.4 or less.
Materials that meet the flammability protocol criteria require high heat fluxes to be ignited; once ignited, these materials can burnlocally in the ignition area, but they are likely not to propagate a fire beyond the ignition zone. Smoke and corrosive productsgenerated from the combustion of these materials are reduced, minimizing nonthermal damages. Research at FM Global suggeststhat materials with a low fire propagation index in NFPA 287, Standard Test Methods for Measurement of Flammability of Materialsin Cleanrooms Using a Fire Propagation Apparatus (FPA), are likely to perform well in a larger-scale flammability test known as theparallel panel test.
Another test standard intended for the same use is ANSI/UL 2360, Standard Test Method for Determining the CombustibilityCharacteristics of Plastics Used in Semiconductor Tool Construction. Testing with ANSI/UL 2360 is conducted using a conecalorimeter fire test apparatus, as described in ASTM E 1354, Standard Test Method for Heat and Visible Smoke Release Rates forMaterials and Products Using an Oxygen Consumption Calorimeter. Results of tests using ANSI/UL 2360 have also been shown tocorrelate with those from the parallel panel test.

Electric immersion heaters and hot plates used in combustible tools or tools using combustible or flammable liquids are examples ofprocess liquid heating systems that need careful review to assure that the proper safety features have been incorporated in thedesign.
A.8.5.5.1
Some organometallic liquids or solids can undergo violent decomposition if overheated, in some cases heating for an extendedperiod below the initiation temperature can also cause the decomposition reaction to occur. These include Trimethylaluminum,
Dimethylzinc, Diethylzinc, Trimethylindium, and Trimethylgallium. Maximum temperatures of 100° o C –120° o C arerecommended.
A.8.5.5.2
A sensor should be located and set at a temperature that prevents degradation of the structural integrity of the heater or itssurrounding materials. Where a low liquid level interlock is installed, the heater overtemperature interlock should preventdegradation at any liquid level above the level at which the low liquid level interlock removes power from the heater. Where a liquidlevel interlock is not installed, the heater overtemperature interlock should prevent degradation at any liquid level—including theabsence of liquid.
A.8.5.5.4
Heater overtemperature interlocks are usually installed to prevent the heater from damaging itself or its surroundings and,depending on the type of heating system, can be required in addition to the liquid overtemperature interlock.

A.8.6.3
The risk assessment for process equipment handling flammable or heated combustible liquids should take account of the following:
(1) When the presence and quantity of flammable liquid is so limited that in the event of a fire it would already be consumedbefore any suppression systems was discharged.
(2) Whether combustible liquids are heated, or capable of being heated, above their flashpoints
(3) Combustible liquids at risk of ignition due to the method of handling (e.g., spraying, atomizing, etc. )
(4) The influence of ventilation, purging, or inerting to prevent ignition
(5) The ability of engineering controls and safety interlocks to prevent overheating, ignition, or fire development
The extent of damage that would occur following ignition is a key factor in the risk assessment, as is the volume and type of smokeand by-products of combustion that are generated.
A.8.11.2
The typical wafer stocker consists of plastic containers holding noncombustible wafers, reticles, or masks, which are stored within astructure that is usually noncombustible apart from vision panels, which are often polycarbonate. The transport system and lightingprovide the only ignition sources within the stockers, however, these are generally separated from the combustible plastics. It isrecognized that stockers are often installed in such a manner that can obstruct ceiling sprinklers, and if a fire were to occur, then thesmoke and heat would cause extensive damage in the cleanroom.
Similarly, stockers in LCD fabs holding glass substrates are often surrounded by polycarbonate vision panels.
The need for protection and the level of protection needed is subject to detailed evaluation and risk assessment, taking account ofrisk management objectives, the quantity and type of combustible materials present, the power rating of electrical equipment, andthe type of electrical protection provided. Protection schemes can include fire suppression systems, which include sprinklers, finewater mists, and smoke detection (possibly interlocked to shut down power to the stocker).
A.8.12.1.1
Vacuum pumps whose construction is susceptible to backstreaming oil into tools should have foreline traps on their inlets.

A.9.3.1
Ribbed flex duct is frequently used to connect a piece of equipment to the exhaust duct system. Trapped sections can occur wherethese ducts are routed under structural members or other mechanical ducts or piping. Furthermore, transport velocities that areadequate in straight sections of ductwork might not be adequate in the aforementioned sections due to turbulence, and as a result,hazardous chemicals can deposit in the ductwork. Ribbed flex duct has the undesirable property of very rapid burn-through orcollapse in the event of internal fire exposure.
The duct system should be designed and constructed to minimize the collection of hazardous chemicals.
FM 4922, Fume Exhaust Ducts or Fume and Smoke Exhaust Ducts, is an appropriate test method for evaluating flexible fumeexhaust duct.
A.9.3.6
Considering fire protection issues only, the following are duct materials listed in descending order of preference:
(1) Metallic
(2) Approved coated metallic or nonmetallic not requiring fire sprinklers, fire dampers, or interrupters of any kind
(3) Combustible with internal automatic sprinkler protection
A.9.4.1
Exhaust flow should be monitored and controlled by a sensor set at a negative static pressure to provide the minimum airflowspecified in Chapter 5.
As an alternative to the foregoing, the minimum airflow can be monitored by periodic inspection to preclude changes caused bymodifications to the exhaust duct system.
In the event a low airflow condition results, a local audible and visual alarm should provide a signal at the tool. The sensor andalarm should be of the manual reset type.
Exhaust static pressure or flow monitoring should be provided on all exhausted tools. Local visual and audible alarms should alsobe provided. The sensor and alarm should be of the manual reset type.
A.9.4.1.1
The estimated concentration should be based on normal operating conditions and take into account a realistic and foreseeablescenario involving a single point failure. This can include a spillage, a leak from a mechanical joint or seal in a ventilated enclosure,or a failure resulting in a maximum flow condition from one source, combined with normal process flows from all other equipmentand process served by the ductwork.
A.9.6.1
Emergency power systems are not intended to keep production equipment operating except in limited cases. When electrical utilitypower in a facility fails, most production equipment will shut down, thereby reducing the hazardous fumes transported in the fumeexhaust duct system.

Risk of reaction of ammonia salts with strong acids where there is inadequate neutralization can be prevented through correctmonitoring and system design. Not previously recognised in NFPA 318 as a risk, but relevant to semi and LCD industries whereTMAH is present in acid waste streams processed in waste water treatment plants by neutralisation.
The mixing of ammonia salts, such as in the residue from TMAH and acids can lead to the formation of nitrogen trichloride. This canthen decompose explosively. There has been at least one incident within the industry that has been put down to this cause. Thisresulted in physical damage to the neutralisation equipment.

Typical configurations of cleanrooms and their chases and plenums create numerous areas that might be sheltered from sprinklerprotection. These areas can include air-mixing boxes, catwalks, hoods, protruding lighting, open waffle slabs, equipment, piping,ductwork, and cable trays. Care should be taken to relocate or supplement sprinkler protection to ensure that sprinkler dischargecovers all parts of the occupancy. Care should also be taken to ensure that sprinklers are located where heat will be satisfactorilycollected for reliable operation of the sprinkler.
Gaseous fire suppression systems are not substitutes for automatic sprinkler protection. The large number of air changes incleanrooms can cause dilution or stratification of the gaseous agent.
It is recommended that sprinkler systems be inspected at least semiannually by a qualified inspection service. (See NFPA 25,Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems.) The length of time between suchinspections can be decreased due to ambient atmosphere, water supply, or local requirements of the authority having jurisdiction.
Prior to taking a sprinkler system out of service, one should be certain to receive permission from all authorities having jurisdictionand to notify all personnel who might be affected during system shutdown. A fire watch during maintenance periods is arecommended precaution. Any sprinkler system taken out of service for any reason should be returned to service as promptly aspossible.
A sprinkler system that has been activated should be thoroughly inspected for damage and its components replaced or repairedpromptly. Sprinklers that did not operate but were subjected to corrosive elements of combustion or elevated temperatures shouldbe inspected and replaced if necessary, in accordance with the minimum replacement requirements of the authority havingjurisdiction. Such sprinklers should be destroyed to prevent their reuse.
A.11.1.4.4
The use of quick-response sprinklers, while still delayed in opening by the downward airflow, would respond to a smaller-size firemore quickly than would conventional sprinklers. (Glass bulb–type quick-response sprinklers might be preferable to other types ofquick-response sprinklers.)
A.11.2.1(1)(a)
Equivalent to 10 in. (254 mm) diameter duct.
A.11.2.1.2.1
Small-orifice sprinklers, 9.5 mm (3⁄8 in.) or larger, can be used.
A.11.2.1.4
Drainage for, and placement of, sprinklers should be designed to prevent water from flowing back into process equipment, toprevent ductwork from collapsing under the weight of the water, or both. Because water discharged into exhaust ductwork will mostlikely be contaminated, outflow from the drain lines should be piped in accordance with local environmental regulations.
A.11.2.1.7
To minimize the effect of automatic sprinkler water discharge on airflow in exhaust ducts, it is preferable to locate the sprinkler headin the workstation transition piece. It is also acceptable to use a 9.5 mm (3⁄8 in.) orifice sprinkler.
A.11.2.2
It is recommended that an approved 9.5 mm (3⁄8 in.) orifice sprinkler be used. Drainage should be provided to remove all sprinklerwater discharged in the pass-through.
A.11.2.4
It is recommended that a listed 57°C (135°F), 9.5 mm (3⁄8 in.) orifice sprinkler be used. It is recommended that a sprinkler beinstalled in all gas cylinder cabinets.
A.11.2.5.2.1
The purpose of the water spray deluge system is to cool the cylinders. The water spray nozzle should be located to maximizecylinder cooling and minimize damage to electrical control systems. Optical detectors could also serve the function required in11.2.5.1.2.
A.11.2.7.1.1
Detection systems to consider include linear heat detection, multiple types of smoke detection, optical flame detection, and videotechnology detection. The preferred optical flame detection systems are combination ultraviolet/infrared (UV/IR) flame detectiondevices that sense radiation from both the ultraviolet and infrared spectrums and use the combined technologies to indicate a fireshall be installed internal to the tool at locations as specified by the limits of the detection system detailed by the manufacturer toprovide for a complete field of view of all affected compartments.

Quick PrintAnnex C Production and Support Equipment
This annex is not a part of the requirements of this NFPA document but is included for informational purposes only.
C.1 Introduction.
Chapter 10 can be used to minimize known fire hazards inherent in the construction and operation of cleanroom tools. Propermaterials, regulatory requirements, and good practices should be considered in the design, use, and maintenance of all tools.
Where hazards cannot be eliminated, no single failure should result in an exposure situation that places people in jeopardy. All fireprevention or protection systems used internal to, or with, equipment should be fail-safe.
C.2 General Recommendations.
Tools should be designed to achieve fire prevention or, in the event of fire, to provide early detection and suppression adequate toprevent fire spread, explosion, or threat to life safety. The completed system should have a third-party review based on therequirements of Chapter 8. Where available, components and subassemblies used should be listed.
The following guideline sets forth areas of consideration when tool design drawings are being reviewed. This list includes onlyrecommendations — design review should not be limited by, or to, these items:
(1) Materials of construction (flammability, combustibility, and compatibility)
(2) Electrical components, their mounting, and enclosures
(3) Electrical circuit protection
(4) Access to components within equipment
(5) Minimization and control of pyrophoric chemicals
(6) A review of process piping, connectors, and materials
(7) Methods of preventing excess flow of gases
(8) Earthquake stability where and when applicable
(9) Redundant controls of electrical heaters
(10) Software interlocks
Tools should bear a nameplate identifying the manufacturer by name and address and the model and serial number of the tool.
Tool manufacturers should notify owners of inherent defects that affect fire and safety as soon as they become known. Likewise,users should notify tool manufacturers of potential fire and safety considerations.
Tool manufacturers should conduct ongoing programs of quality assurance, safety research, and investigation to identify, correct,and inform users of any potential operating malfunctions that might constitute fire safety hazards that could exist in their products.
All known hazards that cannot be engineered out of a tool should be clearly identified and controlled. These conditions should beaddressed specifically in the tool's operation and maintenance manuals or in a notice accompanying the tool.
Plans and specifications for tools, prior to their fabrication or use, or both, should be reviewed and signed by a trained employee orindependent third party using the requirements of Chapter 8.
The maintenance and operation manuals should provide guidance for the posting of appropriate signs on tools to indicate thatmaintenance is in process.
C.3 Administration.
Owners should designate a responsible individual in their employ to review drawings of tool and system designs and to ensure thattools will be in conformance with these requirements.
Owners should perform physical inspection of tools on their receipt to ensure they are in conformance with their design and reviewdocuments.
Owners should ensure that tools are accompanied with adequate installation, maintenance, and operating instructions, includingappropriate wiring details and facilitation of the tool.
Owners should ensure that a proper hands-on training program in the safe operation of a tool is instituted and that standardizedexaminations are given to test knowledge and ability.
Owners should institute an appropriate maintenance program to ensure that all safety controls will work in a proper manner andwhen required. Qualified personnel should inspect and conduct maintenance against a checklist on a sufficiently frequent basis toensure continued safe operation of the tool. The name of the inspector and the date of last inspection should be posted on or closeto each tool.
Production and support equipment can be designed to comply with SEMI S2-0703a, Environmental, Health, and Safety Guidelinefor Semiconductor Manufacturing Equipment, and designed and installed in accordance with Sections 8.1 through 8.14.

1. The industry needs these gases in the fabrication area (subfab) as low vapor pressure gases need to be close to the tool and need to be in the subfab due to the inability to deliver these gases with excessive line lengths.2. Fabs are getting larger, which increases gas line lengths to the tools, which makes low vapor pressure gases hard to located in an HPM room for a larger fab, and increases the volume of subfab gas installations for low vapor pressure gases – larger fabs, more tools. When the 9000 cu ft criteria was established, fabs we typically in the 50,000 ft3 range. The first 100, 000 fabs we seen in the US in the 1990's, and now the are becoming even larger.3. 450 MM is increasing the volumes of material usage, as well as the fab square footage.4. Density limits are the norm in Table 7.1.3 for liquids and solids and there is a precedent that this is effective. Larger fabs can work with this limits due to the restriction being normalized versus an absolute limit.5.

7.1.3.2
Material for tubing, piping, and fittings used for distribution of compressed gases or hazardous productionmaterial gases shall be compatible with those gases.
Statement of Problem and Substantiation for Public Comment
The new term, hazardous production material gases may not be encompassing enough to cover all hazardous gases. This new definition only addresses those gases with a 3 or 4 health hazard rating. There are compressed gases with health rating of other than 3 or 4 for which material compatibility must be considered. For example, the requirements in 7.1.3.2 would not apply to compressed oxygen (health hazard = 0), but oxygen does warrant such safety consideration. Adding the term “compressed gases” as defined in 3.3.4 would extend the requirements in 7.1.3.2 to gases such as oxygen. Oxygen materials compatibility is dependent on many factors and thus, materials compatibility in oxygen is application-specific. In general, acceptance criteria for materials in a given oxygen application depend on two key factors, flammability and ignitability.

Public Comment No. 9-NFPA 318-2013 [ Section No. 11.2.5.2.2.2 ]
11.2.5.2.2.2
The system shall be designed to provide a density of 12 mm 12 lpm / min m 2 (0.30 gpm/ft 2 ) overthe external surface area of the trailers for a 2-hour duration.
Statement of Problem and Substantiation for Public Comment
Mm/min is an incorrect a unit of measure for this context, referring to velocity and not density. Lpm/m2 (liter per minutes per square meter) is proper unit of measure for density in the context of 11.2.5.2.2.2, and corresponds to the US unit of measure.

Committee Statement
CommitteeStatement:
1. The industry needs these gases in the fabrication area (subfab) as low vapor pressure gasesneed to be close to the tool and need to be in the subfab due to the inability to deliver these gaseswith excessive line lengths.
2. Fabs are getting larger, which increases gas line lengths to the tools, which makes low vaporpressure gases hard to located in an HPM room for a larger fab, and increases the volume of subfabgas installations for low vapor pressure gases – larger fabs, more tools. When the 9000 cu ft criteriawas established, fabs we typically in the 50,000 ft3 range. The first 100, 000 fabs we seen in the USin the 1990's, and now the are becoming even larger.
3. 450 MM is increasing the volumes of material usage, as well as the fab square footage.
4. Density limits are the norm in Table 7.1.3 for liquids and solids and there is a precedent that this iseffective. Larger fabs can work with this limits due to the restriction being normalized versus anabsolute limit.
5. Fabs have shown a good history of safely managing toxic and flammable gases with safetycontrols such as exhausted gas cabinets, continuously welded gas lines, and gas detection withauto-shutdown.

The new term, hazardous production material gases may not be encompassing enough to cover allhazardous gases. This new definition only addresses those gases with a 3 or 4 health hazard rating.There are compressed gases with health rating of other than 3 or 4 for which material compatibilitymust be considered. For example, the requirements in 7.1.3.2 would not apply to compressed oxygen(health hazard = 0), but oxygen does warrant such safety consideration. Adding the term“compressed gases” as defined in 3.3.4 would extend the requirements in 7.1.3.2 to gases such asoxygen. Oxygen materials compatibility is dependent on many factors and thus, materialscompatibility in oxygen is application-specific. In general, acceptance criteria for materials in a givenoxygen application depend on two key factors, flammability and ignitability.
