...to a maximum of 5 micrograms per cubic meter of hexavalent chromium as. an 8-hour time weighted average (TWA). Therefore, it is very important to. identify and utilize effective techniques to control the release of hexavalent. chromium into the workplace air. The Sentry Air Systems Model 300 welding...

Dusts can come from grinding or cutting. Fumes can be generated during torch cutting and welding operations. Exposure to hexavalent chromium fumes poses a health risk to humans. To address these risks, OSHA lowered the permissible exposure limit to a concentration level of 5 micrograms per cubic meter...

...in these manufacturing applications as well as in the thermal cutting and welding of stainless steel and in the application of chromium laden paints and coatings. The new standard lowers the Permissible Exposure Level (PEL) from 52 to 5 micrograms/cubic meter. Hexavalent chromium may be monitored by one of several...

Technologies was in compliance. with the pre-existing hexavalent. chromium limits of 52 micrograms. per cubic meter of air (52 µg/m3). But when OSHA lowered the hexa-. valent chromium permissible expo-. sure limit (PEL) by a factor of 10, to. an eight-hour, time-weighted aver-. age exposure limit...
