Public Input No. 31-NFPA 33-2018 [ Global Input ]

Remove “ANSI” and “Standard for” from UL standards throughout the document.

Statement of Problem and Substantiation for Public Input

Removal of repetitive wording and removal of ANSI because many years ago, UL preferred the ANSI/UL reference because there was a transition of traditional UL standards towards an ANSI standards development process. Now, years later, a large majority of UL Standards are ANSI approved and follow the ANSI development and maintenance process. However, sometimes readers are confused because they don't understand the standards are UL standards, not developed by ANSI. There are many other references to standards promulgated by different standards development organizations where they are considered ANSI approved but do not include ANSI in the reference.

A means of egress is provided that meets the requirements of 5.1.4 .An access means is of this Standard and shall have an access means provided for emergencyresponse personnel that is acceptable to the Authority Having Jurisdiction .


Booths installed in accordance with this Standard and NFPA 30 will have a means of egress provided. Additionally, there are no requirements for emergency response personnel access in this Standard and due to local factors, the AHJ should have the authority to mandate their own access for emergency operations.






4.5 Limited-Combustible Material.

A material shall be considered a limited-combustible material where both of the followingconditions of 4.5.1 and 4.5.2, and the conditions of either 4.5.3 or 4.5.4, are met. [5000:7.1.4.2]

4.5.1

The material does not comply with the requirements for a noncombustible material inaccordance with Section 4.4. [5000:7.1.4.2(1)]

4.5.2

The material, in the form in which it is used, exhibits a potential heat value not exceeding 8141kJ/kg (3500 Btu/lb) where tested in accordance with NFPA 259. [5000:7.1.4.2(2)]

4.5.3

The material has a structural base of a noncombustible material with a surfacing not exceedinga thickness of 3.2 mm (⅛ in.) where the surfacing exhibits a flame spread index not greater than50 when tested in accordance with ASTM E84, Standard Test Method for Surface BurningCharacteristics of Building Materials, or UL 723, Standard for Test for Surface BurningCharacteristics of Building Materials. [5000:7.1.4.2.1]

4.5.4

5.5 * 5 Separation from Other Operations.

Spray booths shall be separated from other operations by a minimum distance of 915 mm (3 ft)or by a partition, wall, or floor/ceiling assembly having a minimum fire resistance rating of1 hour; multiple connected spray booths shall not be considered as “other operations” exceptas provided for in Section 13.3.

5.5.1 Multiple spray booths connected by a opening for moving the workpiece or that share acommon wall shall not be considered as "other operations".

5.5.2 For spray booths adjacent to rooms or equipment used for drying, curing or fusing,the separation requirements of Chapter 13.5 shall apply.5.5.3

Spray booths shall be installed so that all parts of the booth are readily accessible for cleaning.

5.5.2 4

A clear space of not less than 915 mm (3 ft) shall be maintained on all sides and above thespray booth, and shall be kept free of any storage or combustible construction.

5.5.2 4 .1

The requirement in 5.5.2 shall not prohibit locating a spray booth closer than 915 mm (3 ft) to ordirectly against an interior partition, wall, or floor/ceiling assembly that has a fire resistancerating of not less than 1 hour, provided the spray booth can be maintained and cleaned.

5.5.2 4 .2

The requirement in 5.5.2 shall not prohibit locating a spray booth closer than 915 mm (3 ft) to anexterior wall or a roof assembly, provided the wall or roof is constructed of noncombustiblematerial and provided the spray booth can be maintained and cleaned.


The proposed changes are intended to help clarify what is considered an "other operation". Multiple booths connected by a conveyor are common and are often treated as one fire protection area. The separation distance for spray booths connected to rooms for drying and curing (ovens) is covered in Chapter 13.5.

The contents of waste containers shallbe placed in a designated storage location.


Rags or cloths saturated with flammable or combustible sprayed materials (from clean-up activities, for example) can be subject to spontaneous ignition. When discarded, heat is released from these rags as they begin to dry. The heat can become trapped and continue to build-up in larger accumulations of discarded rags. If discarded rags have access to oxygen - such as those discarded in an open waste container - the rags could ignite and fire could spread to other areas of the property. By equipping waste containers with a self-closing, tight fitting lid or cover, you are essentially removing the 'oxygen' element of the fire triangle, thus preventing a fire from developing.

If spraying in a prep station is permitted, the spraying operation and area then becomes a limited finishing workstation. Spraying should not be conducted in a prep station. If a prep station is designed for spraying, it should be considered a limited finishing workstation that subsequently allows for prepping operations.






14.3.8.1

Where industrial air heaters are used to elevate the air temperature for drying, curing, or fusingoperations, a high-limit switch shall be provided to automatically shut off the drying apparatus ifthe air temperature in the limited finishing workstation exceeds the maximum discharge-airtemperature allowed by the standard that the heater is listed to or 93°C 165°C (200°F 329°F ),whichever is less.








15.5.1 General.

15.5.1.1

Spray areas for manual or automated spray application processes , as defined in this standard,shall be protected with an approved automatic fire protection system.

15.5.1.2

The requirement in 15.5.1.1 shall apply to both manual and automated spray applicationprocesses.


Sections are combined to provide clarity for readers.






15.5.2.2

The fire alarm and fire protection system shall be supervised in accordance with NFPA 72.


The reference to a fire alarm is removed. A fire alarm system is not required for powder coating operations. The fire protection system can still be supervised without a full fire alarm system. The reference to a fire alarm system is confusing and leads users of the document to believe that a fire alarm system is required.






15.5.3.1 Emergency Shutdown.

For automated spray application operations, one or more manual emergency system shutdownstations shall be installed to serve each spray area in accordance with the followingrequirements:

(1) When activated, the stations shall accomplish at least the functions listed in 15.5.3 and15.5.8.1 .


(3) If access to the station required in 15.5.3.1(2) is likely to involve exposure to danger, anadditional station shall be located adjacent to an exit from the area.


If PI 21 is accepted by the committee, this section can be removed as it is incorporated into PI 21.






15.5.8* Protection for Automated Powder Application Equipment.

For automated spray application operations, activation of the automatic fire protection systemshall automatically accomplish all of the following: (1) Activate a local alarm in the vicinity of the spraying operation (2) Transmit an alarm signal to the facility’s fire alarm system, if such is provided (3) Shut down the coating material delivery system (4) Shut down all spray application operations (5) Stop any conveyors into and out of the spray area

15.5.8.1

Automated powder application equipment , both listed and unlisted, shall be further protectedby listed optical flame detection, installed and supervised in accordance with NFPA 72.

15.5.8.1.1

The optical flame detection shall, in the event of ignition, react to the presence of flame withinone-half (0.5) second and shall accomplish all of the following:

(1) Stop any conveyors into and out of the spray area

(2) Shut off ventilation make up air

(3) Shut off application, transfer, and powder collection equipment

(4) Close segregation dampers in associated ductwork to interrupt airflows

(5) Disconnect power to the high-voltage elements in the spray area and de-energize thesystem

15.5.8.2



Automated powder application equipment that is unlisted shall be further protected by thefollowing:In addition to meeting the requirements in 15.5.3 and 15.5.8.1 , the

15.5.8.2.1

The requirements of 15.5.8.2 1.1 (6) shall not apply to a closed-head wet pipe automaticsprinkler system.


This PI is for formatting and for easier reading of the Standard. Unnecessary text has been removed without changing the intent of each section or the function of the fire protection system. The provision for listed and unlisted devices has been removed. History of incidents in the industry show that unlisted devices are safer, yet create a code enforcement dilemma with the allowance for unlisted equipment. Listed and unlisted equipment should be protected equally allowing for the committee to remain silent on the use of unlisted devices.






17.7.2

Excess catalyzed resin, while still in the liquid state, shall be drained into an open-top,noncombustible container. Enough water shall be added to the container to cover the containedresin by at least 50 mm (2 in.). a steel container of no more than 55-gallons capacity. Thecontainer shall be located in an area with sprinklers if inside the building, be allowed to be nomore than 75% full, and kept covered (but not sealed) except when adding or mixing material.Scrap resins added to the container shall contain no more than 3% initiator, by weight.


Excess catalyzed resin will react to form inert solid material. The proposed new language limits any hazards potentially associated with storage and reaction of scrap resin by liming the size of the container and the amount of initiator contained in the resin, and requiring the container to be located in a spinklered area if inside the building. To accommodate the reaction without rupturing the container, a minimal amount of open headspace is required as well as covers that allow venting.

Remove “ANSI” and “Standard for” from UL standards throughout the document.


Removal of repetitive wording and removal of ANSI because many years ago, UL preferred the ANSI/UL reference because there was a transition of traditional UL standards towards an ANSI standards development process. Now, years later, a large majority of UL Standards are ANSI approved and follow the ANSI development and maintenance process. However, sometimes readers are confused because they don't understand the standards are UL standards, not developed by ANSI. There are many other references to standards promulgated by different standards development organizations where they are considered ANSI approved but do not include ANSI in the reference.

Materials shall be considered limited-combustible materials where tested in accordance withASTM E2965, Standard Test for Determination of Low Levels of Heat Release Rate forMaterials and Products Using an Oxygen Combustion Calorimeter, at an incident heat flux of 75kW/m 2 for a 20-minute exposure, and both the following conditions are met: (1) The peak heat release rate shall not exceed 150 kW/m 2 for longer than 10 seconds. (2) The total heat released shall not exceed 8 MJ/m 2 . [5000:7.1.4.2.3]

4.6.6

Where the term limited-combustible is used in this standard, it shall also include the termnoncombustible. [5000:7.1.4.2.3 4 ]


The requirements for limited combustible materials have been updated in NFPA 5000 by adding another alternative, based on testing to ASTM E2965. This PI simply updates the extract. A companion PI (PI 8) will add ASTM E2965 into the section on referenced ASTM standards.










4.7 Classification of Liquids.

4.7.1 A liquid is any material that (1) has a fluidity greater than that of 300 penetrationasphalt when tested in accordance with ASTM D5, Standard Test Method for Penetrationof Bituminous Materials, or (2) is a viscous substance for which a specific melting pointcannot be determined but that is determined to be a liquid in accordance with ASTMD4359, Standard Test for Determining Whether a Material is a Liquid or a Solid.Combustible liquids are classified according to Section 4.7.6. [30:3.3.33]4.7.2 Combustible Liquid. Any liquid that has a closed cup flash point at or above 100°F(37.8°C), as determined by the test procedures and apparatus set forth in Section 4.7.2. Flammable liquids are classified according to Section 4.7.5.[30:3.3.33.1]4.7.3 Flammable Liquid. Any liquid that has a closed cup flash point below 100°F(37.8°C), as determined by the test procedures and apparatus set forth in Section 4.7.3,and a Reid vapor pressure that does not exceed an absolute pressure of 40 psi (276 kPa)at 100°F (37.8°C), as determined by ASTM D323, Standard Test Method for VaporPressure of Petroleum Products (Reid Method). [30:3.3.33.2]4.7.4 Any liquid within the scope of this standard and subject to the requirements of thisstandard shall be classified in accordance with this section. [30:4.3]

4.7.1 5

Flammable liquids, as defined in 3 4 . 7. 3 .8.2 , shall be classified as Class I liquids and shall befurther subclassified in accordance with the following:

(1) Class IA Liquid — Any liquid that has a flash point below 22.8°C (73°F) and a boiling pointbelow 37.8°C (100°F)

(2) Class IB Liquid — Any liquid that has a flash point below 22.8°C (73°F) and a boiling pointat or above 37.8°C (100°F)

(3) Class IC Liquid — Any liquid that has a flash point at or above 22.8°C (73°F), but below37.8°C (100°F)

[30:4.3.1]

4.7.2 6

Combustible liquids, as defined in 3 4 . 3 7 . 8.1 2 , shall be classified in accordance with thefollowing:

(1) Class II Liquid — Any liquid that has a flash point at or above 37.8°C (100°F) and below60°C (140°F)

(2) Class III Liquid — Any liquid that has a flash point at or above 60°C (140°F)

(a) Class IIIA Liquid — Any liquid that has a flash point at or above 60°C (140°F), butbelow 93°C (200°F)

(b) Class IIIB Liquid — Any liquid that has a flash point at or above 93°C (200°F)

[30:4.3.2]


This moves the requirements for a material to be a liquid and to be a combustible and a flammable liquid from the definitions section into the section where they are actually being classified. This puts all



the information together, where it belongs and eliminates from the terminology section definitions that contain requirements. A companion PI (PI 6) will point to this section from the section on definitions.








6.7.1

Luminaires that are attached to the walls or ceilings of a process enclosure but are outside anyclassified area and are separated from the process area by glass panels that meet therequirements of 5.2.2 shall not be required to be suitable listed for use in ordinary hazard(general purpose) locations. Such fixtures shall be serviced in hazardous classifed locations.Such luminaires shall be capable of being serviced from outside the enclosure.


NFPA 70 National Electrical Code (NEC) Section 410.6 requires that all luminaires be listed. Replacing the term “suitable” with “listed” will provide clarity that luminaires must be listed by a nationally recognized testing laboratory. Replacing the term “ordinary hazard (general purpose)” with “unclassified” will bring NFPA 34 into alignment with NFPA 33 and NFPA 70 NEC where the term “unclassified” is used to refer to areas that are not classified as Class 1, Class 2 or Class 3 hazardous (classified) locations. The term “Lighting Fixture” was replaced in the 2002 edition of NFPA 70 with the term “Luminaire”. The term luminaire is used internationally for lighting products.








6.7.2

Luminaires that are attached to the walls or ceilings of a process enclosure, are located withinthe Class I, Division 2 or Class I, Zone 2 location, and are separated from the process area byglass panels that meet the requirements of 5.2.2 shall be suitable for use in that location. Suchfixtures be listed in accordance with UL 844 Luminaires for Use in Hazardous (Classified)Locations for such Division locations, or UL 60079-0 Safety for Explosive Atmospheres-Part0:Equipment-General Requirements, for such Zone locations. Such luminaires shall beserviced from outside the enclosure.
