Control Dust for Cleaner Workspace

sander-concentrate-ThinkstockPhotos-520165591.jpgDust accumulation of more than 1/32 of an inch – or 0.8 millimeters – covering at least 5 percent of a room’s surface poses a significant explosion hazard, according to the Quincy, MA-based National Fire Protection Association. This dust accumulation is about as thick as a dime or paper clip.

An industrial hygienist should test the workplace for exposures if air quality and dust are concerns, Gray said.

NFPA 654 – a standard on preventing fire and dust explosions – addresses identifying hazard areas, controlling dust and housekeeping. The standard states that vacuuming is the “preferred” method of cleaning. Sweeping and water wash-down are other options. “Blow-downs” using compressed air or steam is allowed for inaccessible or unsafe surfaces.

Industrial vacuums can clean walls, ceilings, machinery and other places, CCOHS notes.

“You want to use wet methods or have high-efficiency vacuum systems,” said Steve Ahrenholz, senior industrial hygienist at NIOSH’s Division of Surveillance, Hazard Evaluations and Field Studies. “You don’t want to use just a shop vac or dry-sweep it – definitely not using compressed air to blow it. [Then] you’re just re-suspending the dust and distributing it all over.”

Dust also can affect equipment’s length of life and quality of products, Ahrenholz added.
