Assuring the highest level of safety in the workplace is essential for every employee under the sun. Regardless of one’s role or workplace environment, all employers should be able to guarantee healthful working conditions with suitable training, guidelines, regulations, and assistance.
However, for some modern industries that operate solely with prevalent work hazards, the only possible method for employees to work is to work safely. Compared to traditionally office jobs, industrial jobs that require working outside with external elements or working with potentially dangerous materials are recognizably more hazardous. For this reason, people in these roles need greater safeguarding measures against sudden explosion, combustion, or exposure to high heat. Now, this is where the National Fire Protection Association (NFPA) enters the picture, aiming to guarantee the protection of industrial personnel against fire-related risks.
Any employer or employee in an industry that deals with fire-related jobs should know the relevant standards of the National Fire Protection Association. Understanding the broader ins and outs of NFPA 2112 standards offers a clear advantage: minimizing the risk of harm or fatal injury while on the job. Why is this defined guidance by the NFPA so significant for industrial environments today? Here’s everything you need to know about NFPA 2112.
The National Fire Protection Association
Established in 1896, the National Fire Protection Association (NFPA) is a leading international nonprofit organization that aims to reduce the hazardous burden of fires around the globe. The NFPA develops authoritative consensus codes and standards to minimize fire risks as the world’s most vital advocate of proper fire prevention. It’s also a guiding resource for general public safety and a provider of continual research, training, and education on the possibilities of fire’s hazardous effects.
Past tragic blazes—and their unfortunate outcomes—have resulted in adjustments and improvements made to NFPA standards. While many consensus codes and standards established by the NFPA relate to public and residential buildings, a great deal relate to boosted safety at commercial or industrial workplaces. NFPA 2112 is one such standard aimed to protect industrial workers against flash fire with the use of protective garments.
What’s the Purpose of NFPA 2112?
NFPA 2112 is a standard that establishes the minimum requirements of the flame-resistant garments used by employees on the job in fire-related industries. This standard is essential for both manufacturers and certifying agencies, offering clear instructions about the design, construction, testing, and certification of flame-resistant fabric and clothing.
Essentially, these specific protective garments must meet performance requirements and evaluation methods to protect workers against the risks of flash fire exposure and resulting injuries.
Applicable Industries and Workplaces
The flame-resistant garments mentioned in the NFPA 2112 standard are for wearers who work in areas at risk of short-term thermal exposure, such as work environments with combustible dust or flammable gases or vapors. Some of the most common industries include the oil and gas industry, metal welding sites or foundries, mining operations, electrical utility, pipeline services, chemical plants, and more.
The Scope of the NFPA 2112 Standard
As you learn everything you need to know about NFPA 2112, keep the scope of the standard in mind. The main applicable hazards related to this standard are the risk of flash fires. Again, FR clothing garments must meet the performance, design, and certification 2112 requirements when these risks are present in the workplace.
The initial blast is not the only environmental danger. For this reason, OSHA—the Occupational Safety and Health Association—also cites this standard. OSHA prohibits workers in these industries from wearing non-FR clothing in the presence of potential hazards that could increase the extent of an injury. For example, if the garment in question were to ignite, burn, or melt onto the skin. If a flash fire were to occur, these garments should not further contribute to the burn injury of the wearer.
The Risk of Short-Duration Thermal Exposure
A flash fire occurs when concentrated fuel levels combine with oxygen and cause combustion unexpectedly. Short-duration flash fires characteristically have a high heat flux, spread rapidly with a front flame, and last three seconds or less. Flammable liquid, vapor, or gas generally cause these intense and sudden fires after igniting in the air.
While these flash fires don’t last long, their damage can be severe to exposed and unprotected skin. Ergo, wearing flame-resistant or self-extinguishing clothing that meets NFPA 2112 requirements can significantly reduce the severity of endured burn injuries.
FR Clothing Requirements
All flame-resistant clothing must meet the following guidelines to provide a certain level of protection and comply with NFPA 2112:
- Achieve less than a 50 percent predicted body burn due to three seconds or less of exposure
- Resist melting, dripping, or after-flame burning with the right fabric and components
- Feature visible and appropriate labeling of certification by an authorized testing body
- Pass all tests and meet all design and construction requirements
Minimum Performance and Limitations
Again, NFPA 2112 garments that pass testing ensure less than a 50 percent body burn within a three-second exposure. The priority is to provide the best protection from short-duration thermal exposure. Flame-resistant clothing that meets this minimum requirement offers a reduced risk of severe burn injury. Instead of enduring second-degree or third-degree burns, the wearer of the FR compliant clothing may suffer minor burns from the sudden intensity of the heat.
Remember that 2112 doesn’t account for longer-duration flash fires or higher temp fluxes from more combustible metal flash fires. NFPA 2112’s pass/fail criteria may not be sufficient, depending on the levels of protection your industry requires. Those who need a greater degree of protection should ensure the correct level of personal protective equipment for their particular work environment. Individual workers should always understand these standards and wear FR clothing on the job that provides adequate performance, efficiency, functionality, and comfort.
