Scenarios

A worker is exposed to 50 parts per million (ppm) of Benzene. Benzene has a Permissible Exposure Level (PEL) of 10 ppm. The worker wants to use a half-mask, air-purifying organic vapor cartridge respirator.

10 (Protection factor for half-mask respirator)

X 10 (PEL of 10 parts per million for Benzene)

= 100 (Max. permissible safe concentration for this situation)

10

A worker will be exposed to 600 micrograms per cubic meter of lead during a paint removal operation. Lead dust has a PEL of 50 micro grams per cubic meter.

The worker wants to use a disposable, air-purifying, high efficiency particulate air (HEPA) respirator.

5 (Protection factor for a disposable mask)

X 50 (PEL of 50 micrograms/cubic meter for lead)

= 250 (Max. permissible safe concentration for this situation)
