Grinding Dust | Sentry Air Systems
Once grinding dust has entered the lungs, dust particles can dissolve in the bloodstream resulting in damage or cancer in vital internal organs. Certain types of grinding dust particles, such as cadmium and stainless steel (hexavalent chromium), exhibit carcinogenic properties leading to lung, prostate, liver, kidney or even brain cancer.
Welding Health and Safety Respiratory Protection
Welding Fume is Not a Vapor. Welding fume is composed of particles, so welding respirators should always include particle filtration. Vapor filtration may be required in some cases. This is vapor, not a fume! Vapor cartridges will not filter welding fumes. The key takeaway here is that welding fume is a form of particle, and must be filtered as ...
