Occupational Safety and Health departments require facilities to keep the work areas clean to reduce the risk of fire and/or explosion. In 2008, the Organizational Health and Safety Agency (OSHA) initiated the National Emphasis Program (NEP) on combustible dust. This widespread program provided guidelines for the prevention and control of combustible dust in manufacturing facilities.
OSHA recommends that facilities adopt a comprehensive housekeeping program which includes a properly-equipped Explosion Proof industrial vacuum cleaner to keep dust accumulations to a minimum.
Explosive atmospheres can be caused by flammable gases, mists or vapors or by combustible dusts. If there is enough of the substance, mixed with air, then all it needs is a source of ignition to cause an explosion. “explosion-proof” vacuums are constructed with non-sparking metals (stainless steel, aluminum, brass, etc…) and are equipped with totally enclosed electrical components so there is no source of ignition that can cause a spark, fire and/or explosion.
The entire vacuum (including the hose and tools) is completely grounded so there is no risk of any static build-up. Some industrial vacuum companies offer basic models dressed up with a few anti-static accessories and describe them as suitable for explosive material.
These imposters can still create arcs, sparks or heat that can cause ignition of the exterior atmosphere and overheating that can ignite dust blanketing the vacuum.
An explosion-proof vacuum must be tested and approved by a nationally recognized testing agency such as the Canadian Safety Association (CSA) or Underwriters Laboratories (UL), as it protects buyers from purchasing a poser by providing legal certification that the vacuum can be used in a hazardous location. It ensures every component in the vacuum from the ground up meets strict standards for preventing shock and fire hazards.
OSHA (Occupational Safety and Health Association) and NFPA recommend good housekeeping practices to keep the work areas clean and reduce the risk of fire and/or explosion. Industrial equipment must be certified for use in these hazardous areas to prevent the risk of fire and/or explosions and to provide a safe environment for the worker.
OSHA National Emphasis Program (NEP) on Combustible Dust that calls attention to the agency’s rigorous expectations for combustible dust-related explosion prevention. The NEP also outlines what OSHA auditors will be looking for during their visits, such as dust accumulation of more than 1/32”, the thickness of a paperclip, covering more than 5% of a plant. Since traditional methods like sweeping and compressed air hardly combat fine dust, food manufacturing facilities often attempt to comply with these plant maintenance standards with shop-style vacuums. While these vacuums might be acceptable for general cleaning, using them to collect combustible dust like sugar and cinnamon can be dangerous. What’s more, their use may also violate the requirements set forth in OSHA’s Combustible Dust NEP, which calls for electrical vacuums used in dusty areas to be approved for the hazard-classified location, as required under standard 1910.307(b).
OSHA is reissuing the directive on the Combustible Dust National Emphasis Program to increase its enforcement activities and to focus on specific industry groups that have experienced either frequent combustible dust incidents or combustible dust incidents with catastrophic consequences. OSHA initiated its previous Combustible Dust National Emphasis Program on October 18, 2007. Because of a recent catastrophic accident involving a combustible dust explosion at a sugar refinery, OSHA has decided to intensify its focus on this hazard. The Agency will increase its activities in outreach, training, the creation and dissemination of guidance and educational materials and cooperative ventures with stakeholders, as well as enhancing its enforcement activities through this amendment to the National Emphasis Program.
