Sweeping Dust and Debris Could Blow Your Safety Rating

Sweeping or blowing of fugitive dust during housekeeping is widely discouraged by OSHA and the NFPA for nearly all industries. Seemingly benign, dusts create an assortment of hazards that include flying particles that can lead to eye injury, slip hazards and ergonomic injuries. The most serious hazards surrounding the sweeping and blowing of dust threaten lives, such as respiratoryand explosion hazards. The use of vacuums to remove dust is almost always recommended as a preferred method of removing fugitive dust. Rather than redistributing dust, industrial vacuum cleaners remove dusts and therefore reduce or eliminate the previously mentioned hazards.

Certainly, the most dramatic hazard associated with dust is secondary explosion. So dramatic that it captured the attention of congress which led to bill that directed OSHA to"issue an interim combustible dust rule and an amendment to the Hazard Communication Standard (HCS) in 90 days, and a final rule in 18 months," according to OSHA's Combustible Dust; Advance notice of proposed rulemaking.
With over 4900 violations associated with OSHA's Combustible Dust National Emphasis Program (NEP), the recent news releases aboutthe organization leveling fines at four companies ranging from $63,000 to $137,000 just this year, and increasing local television coverage of combustibledust violations, it should now be clear that OSHA is serious about enforcing current standards.
In response to OSHA's NEP, many facility and safety managers have revamped their housekeeping practices and added industrial vacuum cleaners approved for use in Class II Div II areas to mitigate the possibility of secondary explosions caused by fugitive dust.
However, of the over 1000 inspections that OSHA has completed, only 18 to 22 percent of the facilities were in compliance with OSHA requirements.
"It can sometimes be tough forfacilities," says David Kennedy, GM for VAC-U-MAX's vacuum cleaning division. "They may have gotten approval from the authority having jurisdiction (AHJ) but OSHA can still come in and fine them if they deem that the facility doesn't meet up to combustible dust standards."
VAC-U-MAX, the leading manufacturer of industrial vacuum cleaning systems for production lines and other dust-intensive areas, developed the first air-operated industrial vacuum cleaner to prevent dust explosions.
Although it can be argued that current OSHA standards are ambiguous, hence OSHA's proposed rulemaking on combustible dust, the standards, however daunting to siftthrough, are clearly noted in OSHA's Safety and Health Information Bulletin entitled Combustible Dust in Industry: Preventing and
