Housekeeping

Housekeeping is the cleaning of the work area and equipment from accumulated dust.

Proper work area and equipment cleanup is a very important control. RCS dust accumulates once settled. The re-entrainment of silica back into the air through dry sweeping / use of compressed air creates a secondary exposure hazard that requires control.

The HSRC states ^(source):

Hazardous Dust

2.3.5 In a building where dust or other material could by becoming airborne cause a hazard by restricting vision, or could cause a fire or explosion or be potentially hazardous if inhaled or ingested, it shall without delay be removed by suitable means such as vacuuming, wet sweeping, or wet shoveling, or be suppressed.
