Carhartt Flame Resistant Clothing Guide

Carhartt Authorized DealerDoes your job require flame resistant clothing? If so, this is the place for you. Carhartt has several styles of flame resistant clothing (FRC) available, so to help you choose the right ones we've listed the different options below with a brief description.

To simplify things, we've placed the Carhartt regular fabrics in its own section.


What is INDURA® Ultra Soft®?
INDURA® Ultra Soft® flame resistant fabrics are blends of 88% cotton and 12% high tenacity nylon. The fabrics are engineered to focus the nylon on the face or outer area for increased durability, while the cotton is focused towards the skin for increased comfort.

INDURA® Ultra Soft® fabrics are treated with high-quality flame retardant chemicals that are impregnated into the core of each cotton fiber. These chemicals act as a catalyst promoting the fabric to self extinguish once the source of ignition is removed and charring occurs.

INDURA® Ultra Soft® fabrics are guaranteed to be flame resistant for the life of the garment (provided proper cleaning directions are followed) and are offered in a variety of weights, colors and textures.

Carhartt Flame-Resistant Clothing meets or exceeds the following standards:

The National Fire Protection Agency's (NFPA) 70E is the Standard for Electrical Safety Requirements for Employee Workplaces. It requires employees to wear flame-resistant protective clothing wherever there is possible exposure to an electric arc flash. Although currently a voluntary standard, NFPA 70E is considered a "generally accepted industry standard" and thus OSHA will fine companies under OSHA's general duty clause, which requires employers to take the appropriate steps to protect workers. NFPA 70E is widely accepted throughout general manufacturing as well as the electrical industry.

This section of the Occupational Safety and Health Administration's (OSHA) 29 CFR 1910.269 covers the operation and maintenance of electric power generation, control, transformation, transmission, and distribution lines and equipment. The standard is currently being rewritten and is expected to closely mirror NFPA 70E. Once approved FRC requirements would become law.

NESC 2007
The National Electric Safety Code is the standard used by electric utilities to implement safety procedures for utility workers. NESC is also the standard OSHA uses when enforcing electrical utility safety. The latest revision, NESC 2007, includes flame resistant clothing as a requirement. Similar to NFPA 70E, the NESC standard requires utilities to perform a risk assessment and then to require workers to wear flame-resistant clothing with an effective rating equal to the risk. NESC is effective January 1, 2009.
