Types of Fire Resistant Fabrics

DOE-HDBK-1092-2004

The extent of the employee's injury is dependent on the length of the arc gap, available fault

current, duration of the arc, the distance of the employee from the arc, percentage of the body

burned, the employees age, medical condition, and number of layers of the clothing system.

The proper clothing system will minimize or reduce the burn injury.

7.4.8.3 TYPES OF FIRE RESISTANT FABRICS

Chemically dependent fire resistant fabrics are treated with flame retardant chemicals added to

the fiber or treatments applied to the fabric. These treatments are activated by heat and produce

gases that smother the flame. Typically, these fabrics have a definite life as defined by the

manufacturer. This is usually defined by the number of home or commercial washings the

garment is exposed.

Inherently fire resistant fabrics, by their composition, do not burn in air. The fire resistance of

this fabric is not affected by washing.

7.4.8.4 CLOTHING SYSTEMS

All clothing worn by affected workers should be considered part of the employees protective

clothing system. This includes rainwear, cold weather wear and underclothing. Protective

clothing should provide a good functional fit to increase the protection and comfort of the

clothing. When required, protection can be increased by wearing single or multiple layers of

flame-resistant outer garments over nonmelting clothing. Sleeves and shirts should be fully

buttoned and appropriate neck, head, and hand coverings provided.

RUBBER GLOVES

The following requirements apply:

1. Rubber gloves shall be of appropriate voltage rating for the work being performed. All rubber

gloves shall meet the standards set forth by ANSI/ASTM.

2. Rubber gloves issued for service shall be tested at appropriate voltage levels at intervals not

exceeding 6 months.

3. Leather glove protectors shall be worn over rubber gloves except where leather protectors

are not required by 29 CFR 1910.137 or the appropriate ASTM standard.

4. Rubber gloves should be carried cuff down in a bag, box, or container that is designed for

this purpose. Rubber gloves may be kept inside of leather protectors.

5. Rubber gloves shall be visually inspected and field air-tested before use each day and at

other times if there is cause to suspect damage.

6. Rubber gloves should be uniquely identified (i.e., serial number or other marking). The

results of dielectric tests should be documented.

7. Rubber gloves shall be wiped clean of any oil, grease, or other damaging substances as

soon as possible.
