Industrial Safety


Petrochemical/ Flash Fire

A flash fire is an unexpected, sudden intense fire caused by ignition of flammable solids (including dust), liquids, or gases. It is characterized by high-temperature, short-duration and a rapidly moving flame front.

Flash fires may occur in environments where fuel, typically flammable gas or dust, is mixed with air in concentrations suitable for combustion. Flash fire hazards are most commonly found in oil exploration, petrochemical processing and chemical industry, but flash fires hazards do exist in many other industries (e.g. food processing).

Suitable fire-resistant materials provide crucial protection against flash fire in the following ways:

  • By providing thermal insulation between the body and the heat source.
  • Not igniting, melting or breaking open which seriously aggravates injuries.

A flash fire is defined by NFPA 2112 as: “A fire that spreads rapidly through a diffuse fuel, such as dust, gas, or the vapors of an ignitable liquid, without the production of damaging pressure."

TenCate Protective Fabrics provides a range of materials that meet and surpass the standard requirements for protection from flash fires.
