INJURIES Severe burn injuries

STANDARDS

NFPA ® 2112 FLASH FIRE

The NFPA® 2112 standard on Flame Resistant Clothing for Protection of Industrial Personnel Against Short-Duration Thermal Exposures from Fire.

THE TEST Flame resistant fabrics must pass a comprehensive list of thermal tests, including the following:

BZ31

· ASTM F2700 – Heat Transfer Performance (HTP) Test - This test is a measure of the unsteady state heat transfer properties of garment materials. · ASTM D6413 – Vertical Flammability (Flame Resistance) Test - This test is used to determine how easily fabrics ignite and continue to burn once ignited. · Thermal Shrinkage Resistance Test - This test measures a fabrics resistance to shrinkage when exposed to heat. · Heat Resistance Test - This test measures how fabrics and components react to the high heat that could occur during a flash fire. · ASTM F1930-11 – Thermal Manikin Test This test provides an overall evaluation of how the fabric performs in a standardized coverall design after three-second thermal exposure. · FTMS 191A – Thread melting resistance Thread used in flame resistant garments must withstand temperatures of up to 500°F.
