Safety and confidence are intertwined, especially in industries with fire hazards. While knowing safety protocols is crucial in hazardous environments, some risks remain beyond control. Flame Resistant (FR) clothing is essential Personal Protective Equipment (PPE) for workers exposed to heat and electrocution risks. FR clothing offers more than just heat resistance; it provides warmth in cold conditions and is a thermal barrier against electrical shocks. Professions like firefighters, police officers, and forestry management inherently require FR protection. Additionally, industrial and maintenance professionals handling hazardous products and equipment can significantly benefit from the protective properties of MWG Apparel FR Clothing.

 What is FR Clothing?

Fire-resistant Clothing is indispensable for protecting workers from burns and injuries caused by heat and flames. Designed with specialized materials (such as Aramids/Coated Nylon and Polyester/Nomex, PBI, or Polybenzimidazole/ Modacrylic) treated with flame-retardant chemicals or woven to resist flames, these garments act as a crucial barrier against heat sources. Unlike regular fabrics, fire-resistant materials withstand higher temperatures before melting or igniting, minimizing heat transfer and ensuring compliance with safety regulations. Comfort and durability are key considerations in their design, making them suitable for prolonged wear in demanding environments.

Types of Flame Resistant Apparel

Types of MWG Apparel FR Clothing vary to meet specific safety needs across industries:

  1. FR Shirts and Pants: Designed for daily wear in environments prone to flash fires or electric arcs, these garments offer durable protection.
  2. FR Coveralls: One-piece suits that provide full-body coverage, commonly used in oil, gas, and chemical industries for comprehensive protection.
  3. FR Jackets and Coats: Used in colder conditions or where additional protection against flames is required, ensuring safety without compromising warmth.
  4. FR Lab Coats and Aprons: Essential in laboratories and food service areas to shield against sudden small fires, maintaining safety during critical tasks.

Apart from these clothing types, the whole Flame Resistant Apparel outfit is completed with-

  •       FR Boots: Specifically designed for industrial environments, these boots protect against flame and heat hazards, often featuring slip-resistant soles and electrical hazard protection.
  •       FR Accessories (Belts, Hoods, etc.): Even accessories like belts and hoods are flame-resistant, offering ignition-resistant materials to prevent injuries, particularly in high-risk settings.

How To Choose The Right FR Clothing

Ensuring safety in workplaces exposed to electrical arc flash thermal hazards is paramount. If you are considering buying MWG Apparel FR Clothing for your team, ensure the garment meets specific standards. The ASTM F1506 (American Society for Testing and Materials) sets critical standards for flame-resistant (FR) clothing, mandating that fabrics meet stringent criteria:

  1. Standards Compliance: Ensure the garment meets ASTM F1506 standards. Fabrics, including knitted and woven types, must meet stringent performance criteria to withstand arc flash incidents effectively.
  2. Component Quality: Check that all components, such as threads, bindings, and closures, do not contribute to injuries during electrical arc exposure.
  3. Flame Resistance: Verify that FR fabrics do not drip, melt, or exceed specified thresholds for flame duration and char length, even after repeated washes or dry cleaning sessions.
  4. Labeling: Look for FR clothing that prominently displays compliance details, manufacturer information, care instructions, and the Arc Thermal Performance Value (ATPV).

By prioritizing these factors, you can ensure that your team is equipped with FR clothing that provides reliable protection against thermal hazards. 

Tips for Selecting FR Clothing Based on Hazard Risk Categories (HRC)

Choosing the right level of FR clothing is crucial for workplace safety. Here’s how to dress according to arc flash protection standards to ensure optimal protection in varying hazard environments:

Category 1: Basic Protection

When dressing for low-risk environments, ensure your FR clothing meets a minimum Arc Rating of 4 cal/cm². This includes FR shirts, pants, or coveralls that provide foundational protection against minor arc flash hazards.


Category 2: Moderate Protection

For moderate-risk settings, choose FR apparel with an Arc Rating between 8 cal/cm² and 24 cal/cm². This level of protection should include FR shirts, pants, coveralls, and undergarments to shield against potential arc flash risks effectively.

Category 3: Significant Protection

In environments with heightened arc flash dangers, opt for FR clothing with a minimum Arc Rating of 25 cal/cm². Layering with FR undergarments, shirts, pants, and coveralls ensures comprehensive protection against substantial hazards. 

Category 4: Maximum Protection

When facing extreme arc flash hazards, prioritize FR apparel with an Arc Rating of at least 40 cal/cm². Equip yourself with multilayered FR shirts, pants, and a full flash suite to safeguard against severe incidents effectively. 


Flame-resistant Clothing acts as a crucial safety measure, providing wearers with critical time to escape from intense fires or combustion. Engineered to resist ignition, these garments self-extinguish once removed from heat sources, suppressing flames by depriving them of oxygen. While MWG Apparel FR Clothing significantly reduces the risk and severity of burns, it cannot eliminate them entirely. Despite this, wearing FR apparel in hazardous conditions can make a difference between life and death.
