Table I. - Respiratory Protection for Lead Aerosols

Airborne concentration of
lead or condition of use

Required respirator1

Not in excess of
500 µg/m3.

 




Not in excess of
1,250 µg/m3

 

 

 

 

 

 




 


Not in excess of
2,500 µg/m3.



 

 


 

 

 

 


 

 

Not in excess of
50,000 µg/m3.

 

 

 



 

Not in excess of
100,000 µg/m3.

 

 

Greater than 100,000 µg/m3,
unknown concentration, or
fire fighting.

* 1/2 mask air purifying respirator with high efficiency filters.2,3

* 1/2 mask supplied air respirator operated in demand(negative pressure) mode.

* 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 - e.g., type CE abrasive blasting respirator operated in a continuous- flow mode. * Type C hood or helmet supplied air respirator operated in continuous-flow mode. (For Type CE abrasive blasting respirators operated in continuous flow mode see below.)

 

* 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 demand mode.


* 1/2 mask or full facepiece supplied air respirator operated in continuous-flow mode.

* Full facepiece self-contained breathing apparatus (SCBA) operated in demand mode.

* 1/2 mask supplied air respirator operated in pressure demand or other positive-pressure mode.


* Type CE hood or helmet abrasive blasting respirator operated in a continuous-flow mode.4


* Full facepiece supplied air respirator operated in pressure demand or other positive-pressure mode- e.g., type CE abrasive blasting respirators operated in a positive-pressure mode.

*Full facepiece SCBA operated in pressure demand or other positive-pressure mode.

1 Respirators specified for higher concentrations can be used at lower concentrations of lead.
2 Full facepiece is required if the lead aerosols cause eye or skin irritation at the use concentrations.
3 A high efficiency particulate filter (HEPA) means a filter that is 99.97 percent efficient against particles of 0.3 micron size or larger.
4 These are Type CE respirators with neck cuff or neck sealing feature to help maintain positive air pressure in the respiratory inlet covering.
