• Respirators are provided to protect the health of its employees when hazards exist from breathing dusts, fumes, gases, smoke, etc.

• Employers must develop a written respiratory protection program that includes:– Proper respirator selection

– Medical evaluations

– Fit testing

Certain respirators at Cummins do not provide protection to exposed areas of the body. If the contaminated atmosphere contains vapors, gases or airborne particulate matter which may either irritate or burn the eyes or the skin, or can be absorbed by the body through penetration of the skin, the use of specialized eye, hand and/or body coverings may be required for protection.

= 500 ppm OK

• Methanol TWA

= 200 ppm BAD

Change-Out ScheduleChange-Out Schedule

• Go to an area with uncontaminated breathable air.
