What is the difference between AR clothing and FR clothing?

Both FR (flame-resistant) clothing and arc-proof clothing are used as protective gear in industrial settings. FR clothing is commonly used in fields such as oil, petrochemicals, gas stations, chemical industries, and firefighting, where clothing protection is needed. On the other hand, Arc protection suit is typically worn by electric employees in the electric power and related industries, in environments where potential arc flashes may occur, and during escape from arc explosions.

FR clothing works by slowing down the burning speed of the fabric, which can extinguish itself once the fire source is removed. This helps protect the wearer from burns and scalds and gives them time to evacuate or remove the burning clothing.

AR clothing on the other hand, is designed to protect the wearer from arc flash hazards. When an arc explosion occurs, the fabric rapidly expands, carbonizes, and creates a protective layer between the wearer’s skin and the arc heat.

While both types of clothing offer flame-retardant protection, arc-proof clothing offers a higher level of protection against arc flashes specifically. It also offers other features such as being lightweight, breathable, moisture-permeable, and intrinsically flame-retardant with no molten droplets. Additionally, arc-proof clothing maintains its flame-retardant properties even after washing, making it a more sustainable and cost-effective option for long-term use.
