Respirators are among the
most
important pieces
of safety equipment available. With chemical cartridges, they
can be used to
filter out and protect workers from many different hazards. The media
used in
these chemical cartridges is typically activated carbon which adsorbs a
number
of different chemicals. However, the adsorption capacity is limited.
Recently, OSHA
has addressed this issue in its revised respiratory standard. It is no
longer acceptable to rely on odor thresholds and other warning
properties as
the primary way of determining cartridge life.
Cartridges, filters, and masks get old. Cartridges can have a
limited life. If the filter cartridges that attach to the mask are
outdated, have been open to the air or are damaged, you are not
protected. Cartridges that contain charcoal or other chemicals for
filtering the air should be in air-tight packages. If cartridges are
open or not packed in air-tight packaging, they should not be used.
Even cartridges in original packaging have expiration dates that should
be checked before purchase. Also, over time your mask can get old and
break down. Keep your mask in a clean, dry place, away from extreme
heat or cold. Inspect it according to the manufacturers instructions.
