Study Notes

Hazards and Ignition Sources

  • The primary ignition source for oxygen enrichment hazard is an electrical spark or open flame.
  • The main hazard associated with confinement is explosion.
  • The primary function of effective dust collection systems is to prevent the accumulation of combustible dusts.
  • The purpose of Dust Hazard Analysis (DHA) is to identify and assess the risks associated with combustible dusts.

Hazards and Ignition Sources (continued)
