||Field measurements of half-facepiece respirators - Foundry operations
||Feb. 1996, Vol.57, No.2, p.166-174. 13 ref.
||Workplace protection factors provided by elastomeric and disposable half-facepiece respirators were calculated from the ratio of ambient and in-facepiece concentrations of dust and fume exposures at three foundries. The main components of the airborne exposures were zinc, lead and silicon. The main components of the in-facepiece samples were zinc, chlorine and lead. While significant differences were observed in ambient zinc and lead concentrations among foundries, no significant difference was observed in the in-facepiece concentrations of these elements among foundries. The in-facepiece penetration data clearly indicate that these respirators, when conscientiously used and maintained, and in conjunction with existing controls, provide effective worker protection.
