In workplaces where fire, heat, or electrical hazards are present, protective clothing is not just an option; it is a necessity. Among the most common protective gear are flame-resistant (FR) jackets, designed specifically to reduce the risk of burn injuries. Regular work jackets, while often durable and suitable for general work conditions, do not offer the same level of protection. Understanding the differences between FR jackets and regular work jackets is critical for workers and safety managers to ensure compliance, safety, and overall workplace efficiency.
