04 - Impact of Explosion

It is critical to evaluate the potential for explosion as well as who could be impacted including residents, tenants, visitors, contractors and/or neighboring occupants, including hospitals, schools, railroad, bus depot, etc. The potential for explosion could be on the specific site you are evaluating or on an external exposure site. Potential is an evaluation of the combination of explosive material and the effects of protection from explosion.

What do we look for?

Exposures

  • Excessive and/or inadequate storage of flammable liquids, gases, and/or dusts.
  • High pressure equipment present without adequate protection.
  • Inadequate separation between structures and/or critical external exposures.

Controls

  • No excessive storage and adequate storage of flammable liquids, gases, and/or dusts.
  • Storage areas, ducts, silos, etc. are properly protected.
  • Adequate separation between structures and no critical external exposures.

  • All flammable liquids, gases, dusts etc are well protected in terms of storage, anti-static, containment, extinguishing systems, etc.

  • High pressure equipment is located away from people and external exposures.
