COMBUSTIBLE DUST HOUSEKEEPING INSPECTION CHECKLIST

THE PROBLEM: Dust explosions can occur when accumulations of combustible dusts are set off by heat, electricity, friction, or other ignition source. The key to preventing explosions is keeping combustible dusts away from ignition sources or, better yet, ensuring that dangerous dusts don’t buildup to the level where they can ignite. Housekeeping and the performance of regular inspections is an essential step in keeping dusts from accumulating on floors, work areas and surfaces.

HOW TOOL HELPS SOLVE THE PROBLEM: Here’s a Checklist you can use to ensure that combustible dust housekeeping inspections are carried out effectively at your workplace.
