Respiratory protection from lead

Respiratory Protection for Lead

Lead Level ug/m3 Respirator Required
Not in excess of 500 ug/m3 Half‐facepiece air‐purifying high respirator with high efficiency filters 2,3

Half‐facepiece supplied‐air respirator operated in demand (negative pressure) mode

Not in excess of 1,250 ug/m3 Loose‐fitting hood or helmet‐powered air‐purifying respirator with high efficiency filters 3

Hood or helmet supplied‐air respirator operated in a continuous‐flow mode such as type CE abrasive‐blasting respirators operated in a continuous‐flow mode

Not in excess of 2,500 ug/m3 Full‐facepiece air‐purifying respirator with high efficiency filters 3

Tight‐fitting powered air‐purifying respirator with high efficiency filters 3

Full‐facepiece supplied‐air respirator operated in a demand mode

Half‐or full‐facepiece supplied‐air respirator operated in a continuous‐flow mode

Full‐facepiece self‐contained breathing apparatus (SCBA)

Not in excess of 50,000 ug/m3 Half‐facepiece supplied‐air respirator operated in pressure demand or other positive‐pressure mode
Not in excess of 100,000 ug/m3 Full‐facepiece supplied‐air respirator operated in pressure demand or other positive‐pressure mode such as type CE abrasive‐blasting respirators operated in a positivepressure mode
Greater than 100,000 ug/m3 Full‐facepiece SCBA operated in pressure concentration, or fire‐fighting demand, or other positive‐pressure mode
1.      Respirators specified for higher concentrations can be used at lower concentrations for lead.

2.      Full‐facepiece is required if the lead aerosols cause eye or skin irritation at the concentrations.

3.      A high efficiency particulate filter (HEPA) means a filter that is 99.97 percent efficient against particles of 0.3‐micron size of larger.
