AR/FR Workwear: Arc Flash vs Flash Fire vs Combustible Dust

ARC FLASH/ARC BLAST Arc flashes occur when an electric current passes through air between underground and grounded conductors, causing temperatures reaching up to 35000° F.

ARC FLASH/ARC BLAST

Arc flashes occur when an electric current passes through air between underground and grounded conductors, causing temperatures reaching up to 35000° F. Arc Blasts are waves of pressure that can reach up to 2100 PSI, enough to throw a full grown human and heavy equipment to the ground. Both are serious electrical hazards that can cause serious injuries and fatalities

  • Electricians
  • Electrical Engineers
  • Maintenance Techs
  • HVAC Technicians
  • Facility Managers
  • Utilities
  • Electrical Contractors
  • Linemen
  • Inspectors
  • Equipment Installers

FLASH FIRE

Short duration fires, 3 sec. or less, that can spread rapidly through a diffuse fuel, such as gas or the vapor of an ignitable liquid, without producing damaging pressure and reach up to 1900° F. They are characterized by high temperature, short duration and rapidly spreading. Flash Fires can cause severe burns, injuries, and fatalities.

Flash Fire Prone Industries:

  • Oil and Gas Industry
  • Chemical Manufacturing
  • Fossil Fuel Power Generation
  • Plastics Manufacturing
  • Tobacco Manufacturing
  • Pesticides Manufacturing

COMBUSTIBLE DUST

Fine particles (fabric, wood, metals, plastics, chemicals, food products) that can cause fire / explosion when suspended in air. These particles form a dust cloud, and if exposed to a spark or heat, and can ignite and explode. This often occurs during material processing, handling, or storage.

Combustible Dust Prone Industries:

  • Textile Mills
  • Apparel Manufacturing
  • Lumber Mills
  • Paper/Pulp Manufacturing
  • Wood Products Manufacturing
  • Grain Mills
  • Food Processing
