Standards & Test Methods

Why Do We Wear FR Clothing?

PROTECTION – COMPLIANCE TO STANDARDS– COST SAVINGS
  • First and foremost is the protection it provides from a potential accident.
    • Some Potential Hazards faced: Flash Fire, Arc Flash, Molten Metal, or a Chemical exposure; having the appropriate “FR” Flame Resistant / Protective clothing could be the difference in whether a person survives the incident or doesn’t.
  • The purpose of FR clothing is to protect and not add to the severity of the damage caused in a short duration thermal incident. The standard testing method is at 3 seconds. See F1930 and NFPA 2112.
  • The reaction of a flame resistant garment is to self-extinguish once the fuel source is removed.
    • Unlike a FLAME RESISTANT GARMENT; a non FR garment or standard clothing will ignite and burn. If one is wearing a synthetic garment (polyester or nylon) that fabric could melt and adhere to the skin.
    • The most severe damage in a flash fire or arc explosion is often times caused by the non FR clothing being worn.
    • It is important for the employer and the worker/wearer to understand how to best wear their FR clothing and also what type of non FR clothing is suitable to wear with it to minimize the severity of any burn damage in a thermal incident.
  • Another aspect of wearing FR clothing is selection. Understand the task and hazard potential and choose the best fabric and garment to protect against it.
  • Regulations and Industry Standards are also a factor in one’s decision to be compliant or not. OSHA requires employers to protect their people in the workplace. By not following the compliance standards, one could be subject to fines and / or citations.
  • Overall Cost and Value of your apparel program. By choosing a good fabric and a well-built garment you can actually save money. You can minimize the frequency of replacements if you are utilizing a garment suited for the job being performed.
    • By choosing to protect your team properly; that should provide a peace of mind that you are doing the right thing for them and your company.
    • By selecting the appropriate FR garment, you can minimize spending by not purchasing multiple types and styles of clothing / uniforms. One purchase for the job. You also minimize the risk of the employee wearing the inappropriate garment.
    • Prevent or minimize the expenditure associated to care for an injured employee.
    • Insurance costs could be less by using the proper safety measures.
    • Worker’s compensation and loss time wages.
    • Increase COMPANY IDENTITY = BRAND EQUITY
