Procedure
Coreshield 8 contains very low levels of barium. The TLV for barium will not be reached before the total welding fume limit of 5 mg/m3 is reached. The fumes and slag dust, however, can be irritating and care should be taken to keep these out of the welder's breathing zone. Consult MSDS for more information.
