Flame-resistant (FR) jackets are an essential component of personal protective equipment (PPE) for workers in hazardous environments, such as electrical utilities, oil and gas, manufacturing, and welding. These jackets are specifically designed to protect wearers from thermal hazards, including flash fires, electric arcs, and combustible dust. However, not all FR jackets are created equal. When it comes to safety, durability, and comfort, choosing the right jacket can make a significant difference.
