FLASH FIRE

THE RISK

Flash Fire is a sudden, intense fi re which
is short in duration but severe in potential
danger .

WHO IS AT RISK?
FR89
Workers in industries prone to fl ash fi res
include oil and gas, refi neries, extraction
and pipeline services, gas utility services,
petrochemical plants, mining, and metal or
glass foundries.

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 BZ31
the following:

· 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 fl ash fi re.
· 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 FC19
thermal exposure.
· FTMS 191A – Thread melting resistance Thread used in fl ame resistant garments
must withstand temperatures of up to 500°F.
