NFPA 2112 Flame-Resistant Clothing for Protection Against Short-Duration Thermal Exposures from Fire: what it requires and the equipment it names
NFPA 2112 is the flash fire clothing standard: the one behind "2112" on an FR coverall in oil and gas, refining, chemical plants and utilities. OSHA names no FR standard for flash fire but requires protective clothing under 1910.132 wherever the hazard assessment finds the exposure, and OSHA's 2010 enforcement memorandum on FR clothing in oil and gas drilling points employers to garments meeting 2112. We sell nationwide; ships in 1–2 business days; most orders arrive in 3–7 business days.
The plain answer
NFPA 2112, Standard on Flame-Resistant Clothing for Protection of Industrial Personnel Against Short-Duration Thermal Exposures from Fire, is the NFPA consensus standard for garments worn where a flash fire (a rapidly moving flame front from an ignited gas or vapor release, lasting about 3 seconds) can occur. OSHA does not incorporate it; 29 CFR 1910.132(a) and (d) require protective clothing selected by the hazard assessment, and OSHA's 2010 memorandum on flame-resistant clothing in oil and gas well drilling, servicing and production states that FR clothing is required where flash fire hazards exist and that garments meeting NFPA 2112 meet the intent. NFPA 2113 is the companion on selection, care and use.
As MCR Safety's and the other manufacturers' FR guides state it, a 2112 garment is made of fabric that passes the vertical flame test (ASTM D6413: 2 seconds or less afterflame, 4 inches or less char length, no melt or drip, after 100 launderings), thermal shrinkage of 10 percent or less at 500 °F for 5 minutes, heat transfer performance (HTP) of at least 6 cal/cm² spaced and 3 cal/cm² in contact, and a thermal protective performance test; the whole garment is then tested on an instrumented manikin under ASTM F1930 in a 3-second, 2 cal/cm² per second flash fire (6 cal/cm² total) and must show no more than 50 percent predicted second- and third-degree body burn. Garments are third-party certified (UL is the common certifier) and labeled with the standard, the edition and the certification mark, and the manufacturer publishes the manikin body burn result.
The equipment it names is FR coveralls, shirts, pants, jackets, bibs, rainwear (with ASTM F2733), hoods and balaclavas, and FR hi-vis garments, each certified and labeled NFPA 2112; a garment may also carry an ASTM F1506 arc rating when the manufacturer has tested it, which is a separate test for a different hazard.
What the rule says
Each entry is condensed from the paragraph cited; the paragraph itself is the rule and the link opens it.
29 CFR 1910.132(a): Protective clothing is provided, used and maintained wherever hazards of processes or the environment can cause injury through physical contact, which OSHA reads to include flash fire burns.
29 CFR 1910.132(d): The hazard assessment that identifies the flash fire exposure and selects the clothing.
OSHA enforcement memorandum, March 19, 2010: Flame-resistant clothing in oil and gas well drilling, servicing and production: OSHA states that FR clothing is required under 1910.132 where employees are exposed to flash fire hazards (drilling into known hydrocarbon zones, servicing wells, production facilities), and that FR clothing meeting NFPA 2112 is one way to meet the requirement.
29 CFR 1910.269(l)(8)(iii): For electrical exposures, no clothing that could melt or continue to burn; the same fabrics that pass 2112 pass this test, though 2112 does not give an arc rating.
29 CFR 1910.106 and 1910.119: Flammable liquids and process safety management: the rules that make a flash fire a recognized hazard in refineries and chemical plants, where the 1910.132 clothing duty follows.

What the standard requires, as the manufacturers publish it
Fabric tests: vertical flame resistance under ASTM D6413 with an afterflame of 2 seconds or less and a char length of 4 inches or less, no melting or dripping, tested after 100 industrial launderings (or the care method on the label); thermal shrinkage of 10 percent or less after 5 minutes at 500 °F (260 °C); heat transfer performance (HTP) of at least 6 cal/cm² with a spacer and 3 cal/cm² in contact; thermal protective performance (TPP) for some components; and heat resistance of thread, labels, closures and reflective trim so nothing melts or ignites.
Garment test (ASTM F1930 manikin): a complete garment on an instrumented manikin with more than 100 heat sensors is exposed to a propane flash fire of 2 cal/cm² per second for 3 seconds (6 cal/cm² total); the predicted second- and third-degree body burn, computed from the sensor data, must not exceed 50 percent. Manufacturers publish the result (MCR Safety lists its ASTM F1930 body burn data by style), and a lower percentage is what buyers compare.
Certification and labeling: garments are certified by a third-party organization (commonly UL) that audits the manufacturer and retests, and carry a label with the standard, edition (2018 or 2023), certification mark, fiber content, size and care. NFPA 2113 sets how 2112 garments are selected (hazard assessment, coverage of the body, non-melting undergarments), worn (sleeves down, fully fastened) and maintained (laundering that does not destroy the FR treatment, retirement when worn or contaminated).
Relation to the other FR standards: ASTM F1506 rates arc flash protection in cal/cm² and is required for electrical work under NFPA 70E; NFPA 2112 rates flash fire protection by manikin body burn; a garment can carry both when the manufacturer has run both tests, and MCR Safety's oil and gas guide tabulates which of its styles do. ASTM F2733 is the flash fire rainwear companion, and NFPA 1977 (wildland) and 1971 (structural) are separate firefighter standards.

NFPA 2112 Flame-Resistant Clothing for Protection Against Short-Duration Thermal Exposures from Fire questions
What does NFPA 2112 mean on FR clothing? That the garment was certified to NFPA 2112, the flash fire standard: its fabric passed the vertical flame, shrinkage and heat transfer tests, and the whole garment was exposed to a 3-second flash fire on an instrumented manikin (ASTM F1930) with no more than 50 percent predicted body burn, with a third-party certifier's mark on the label.
What does FR rated clothing mean? Flame resistant: the fabric self-extinguishes when the flame source is removed, measured by the vertical flame test ASTM D6413 (afterflame 2 seconds or less, limited char length, no melting or dripping), either because the fiber is inherently FR or because the cotton or blend is treated. FR by itself is a fabric property; NFPA 2112 certifies the garment for flash fire and ASTM F1506 adds an arc rating for electrical work.
What are the differences between NFPA 2112 and NFPA 70E? Different hazards and different kinds of document. NFPA 2112 is a garment standard for flash fire (a 3-second hydrocarbon fire), tested by manikin body burn; NFPA 70E is a work-practice standard for electrical safety that requires arc-rated clothing (tested and labeled in cal/cm² under ASTM F1506) by incident energy or category. A garment can meet 2112 and carry an F1506 arc rating, and manufacturers label both when they have tested both.
Is FR clothing required by OSHA? OSHA has no rule that says "FR clothing" for flash fire; it requires protective clothing under 1910.132(a) wherever the hazard assessment finds the exposure, and its March 2010 memorandum says FR clothing is required in oil and gas drilling, servicing and production where flash fire hazards exist, naming NFPA 2112 garments as meeting the intent. For electrical arcs, 1910.269(l)(8) requires arc-rated clothing directly.
What does cat 2 2112 mean? A garment that carries both labels: certified to NFPA 2112 for flash fire and rated at 8 cal/cm² or more under ASTM F1506, which meets NFPA 70E PPE Category 2. The two tests are separate; manufacturers list both on the label when the garment has passed both, as MCR Safety's dual-rated styles do.
What is the difference between NFPA 2112 and 2113? 2112 is the garment standard (what the fabric and garment must pass to be certified); 2113 is the companion on selection, care, use and maintenance: the hazard assessment that chooses the garment, how it is worn (fully fastened, sleeves down, over non-melting underlayers), how it is laundered so the FR performance lasts, and when it is retired.
