Thermal spray safety

Sponsored Links

Thermal spray shops have their own unique safety concerns -- hence we have designed this article to address this specifically. Thermal spray process generates a lot of dust. Proper dust collectors are almost a must to be installed. Various state of the art dust collectors are available nowadays. Some of the dust can be flammable -- hence avoid electrical sparks near such areas. Plasma spray process generates a lot of high frequency noise and HVOF process generates a lot of normal frequency noise -- hence proper ear protection devices must be used. Decibel meters can be installed permanently in the high noise areas. Grit blast areas are also high dust areas and dust collection and respiratory protection devices must be used. Acetone and other solvents are typically used in parts cleaning areas -- proper safety precautions must be followed including properly grounding the flammable drums to prevent electric charge build-up. Plasma flame is damaging to the eyes and hence eye-protection goggles must be used -- with notices not to stare at the plasma flame with naked eyes.
