Focus Industry POWER PLANTS | 02/09 | Spill Response Spill response should also be taken into account when purchasing an explosion-proof vacuum. Although OSHA’s National Emphasis Program is specifically looking at companies that handle dry solids, manufacturers’ maintenance plans are also under the microscope. If workers might need to collect flammable or explosive chemicals, a wet-model, explosion-proof vacuum should be considered which is also available in both electric and air-operated versions. Conclusion It is only a matter of when, not if, OSHA will initiate enforced standards for combustible dust procedures, and with power plants being at the top of the agency’s watch list, facilities can guarantee they’ll be seeing an OSHA agent on their doorstep in the near future. Purchasing a high-quality, explosion-proof or intrinsically safe vacuum is a solid first step in preventing a combustible dust-related explosion, and picking the right vacuum often raises a lot of questions, especially when it comes to disaster prevention. Like all investments, pre-sale research is key. Plant managers shouldn’t hesitate to ask the vacuum manufacturer for an onsite analysis of their vacuum needs in order to recommend what type of explosion-proof vacuum, hose and accessories are needed for the application. With the right equipment, the vacuum can be used to collect dust and debris from the floor, machinery, walls and even overhead pipes and vents. Naturally, every manufacturer will be responsive to your needs before you buy, so look for a company that will still be there after the bill is paid. Excellent post-sale support and training will make things easier when it’s time to purchase replacement parts and filters or service the vacuum. p Minimize the escape of dust from process equipment or ventilation systems Use dust collection systems and filters Utilize surfaces that minimize dust accumulation and facilitate cleaning Provide access to all hidden areas to permit inspection Inspect for dust residues in open and hidden areas, at regular intervals p p Clean dust residues at regular intervals Use cleaning methods that do not generate dust clouds if ignition sources are present Only use vacuum cleaners approved for dust collection Locate relief valves away from dust hazard areas Develop and implement a hazardous dust inspection, testing, housekeeping and control program (preferably in writing with established frequency and methods) p p p p p p p www.airbestpractices.com 37 http://www.airbestpractices.com
