Our senior engineer is a member of five NFPA National Committees: 61, , , & the Correlating Committee. This experience, in combination with over years of combined dust collection system design makes uniquely qualified to assist our customers in evaluating and mitigating the risks from handling combustible dusts in both dust collection and material handling applications. View a 60 Minutes segment on “The Danger of Combustible Dust”. Dust Collection System Audits. The management of combustible dust is mandated by safety legislation and regulatory codes. NFPA 69 and Standards cover the design, construction, operation, maintenance and testing of systems for the prevention of deflagration explosions by means of the following methods: Commercial Woodworking Dust Collection Systems Zip (a) control of oxidant concentration; (b) control of combustible concentration; (c) explosion suppression; (d) deflagration pressure containment; (e) spark extinguishing systems.  It’s not uncommon to move a dust collector to a new application, and because you see explosion vents or suppression systems attached to the collector, you might believe you’re Combustible Dust Vacuum Systems Us in good shape. Not necessarily, not without testing the new dust. Remember, identical dust chemistry does not dictate the same Kst or explosivity value. Examples are: Extensive centralised dust collection systems create many links through which burning material can spread following an explosion in the filter. This can be controlled, but filters drawing dust from just one or two locations reduce the risk more simply. Overloading or blockage of the feed system may cause some process plant to overheat.  Despite this, the building will require regular cleaning, and the preferred method is a vacuum system rather than brushes and shovels, which tend to raise dust clouds. You should avoid the use of compressed air lines to dislodge dust deposits, as this will cause unnecessary dangers by creating dust clouds. There is no general preference between mobile vacuum cleaners and a centralised system.

Combustible dust in manufacturing environments has always been one of combustibld major threats for Health and Safety managers.

They are responsible for preventing any possible dangers associated with workers and production plants. Many accidents have happened in the past, but duwt the Imperial sugar disaster inwhere 14 people died as a result of an explosion caused vacum sugar dust, world combusyible were sensitized to the creation of new standards and policies preventing such disasters. An illustration known as the "Explosion Pentagon" shows the elements needed to cause seemingly harmless dust to explode.

NFPA cmobustible a classification of combustible dust vacuum systems example environments based on the type of risk and on its frequency in presence of combustible dust. This is why even non classified environments must comply to the housekeeping and cleaning regulations. Not only the generally recognized hazardous industries as pharmaceutical and petrochemical industries are vulnerable to hazard dust explosions, but also agriculture and food industries; such as feed, flour, candies, spice, duzt, tobacco, grain, fertilizer, plastics, wood, paper, pulp, textiles, combustible dust vacuum systems example, tire and rubber manufacturers, dyes, coal and metal processing aluminium, iron and zinc.

Properly equipped industrial vacuums 2. Brooms, mops 3. Blowguns only where ignition sources are not present. Industrial vacuum cleaners are listed as the preferred method of cleaning as they collect and contain dusts safely, guaranteeing the highest level of cleaning and hygiene much more than blowing or alternative cleaning systems.

Even if the NEP is not an approved regulation, this does not mean that it can considered without penalty. Combustible dust vacuum systems example are some standards that can be used for regular citations. The recommended procedures include:. Bacuum are the only bodies that can provide certifications for electric equipment in the United States. Note: Pneumatic equipment cannot be certified by a NRLT, because there is no certification for pneumatic equipment in the Combusyible States.

For peak safety and operating efficiency, an EXP vacuum should have a multi-stage, graduated filtration system, which uses a series of progressively finer anti-static filters to trap and retain particles as they move through the vacuum. In order to eliminate combustible dust from being exhausted back into the ambient air, a HEPA or ULPA filter. All it takes is one spark for airborne dust to ignite. For the past decade, Nilfisk has led the industry in developing a line of explosion-proof and dust ignition-proof vacuums built from the ground up to help mitigate the threat of combustible dust. Explore this section to learn about the OSHA and NFPA requirements for combustible dust management.
