Enclosed blasting continues to displace chemical processes for cleaning and preparing parts for subsequent coatings. But, liquid chemicals aren’t the only toxins found in a manufacturing plant.
Recent inquiries (and a few warranty cards) from customers cleaning parts made from beryllium copper and other hazardous materials point up the possible dangers of creating toxic dust by blasting.
The standard dust cartridge, such as the ones used on the Pulsar cabinet, traps 99.7 percent of the particles 0.5 microns and larger. Assuming the filter is in good shape, just running a Pulsar cabinet can actually make the ambient air cleaner in a typical machine shop.
When you blast a surface that contains toxic material, however, clean air is never clean enough. High-efficiency particulate air (HEPA) filtration with RP collectors are offered as an option on most ZERO blast cabinets including Pulsars, BNPs, and Automated cabinets.
Mounted after the collector, the HEPA filter captures 99.97 percent of the few dust particles (0.5 micron and larger) not already trapped by the cartridge dust collector.
Before you blast any suspect material, have an industrial hygienist or safety engineer evaluate the risks involved and establish procedures for capturing and disposing of the dust.
