is a condition which is characterized by breathing difficulty,
chest tightness, coughing, wheezing and shortness of breath.
The condition can be serious and sometimes even fatal. While
many asthma sufferers are born with the condition, asthma can
be occupationally-induced. Millions of workers in a wide range
of industries and occupations are potentially exposed to hundreds
of organic and inorganic substances associated with occupationally-induced
of these substances cause sensitization, so that only minor
subsequent exposure will cause an asthmatic condition. Other
substances are non-sensitizing and therefore require a full
dose for an asthmatic condition to result. Only a few of these
substances have OSHA Permissable Exposure Limits (PELs) and/or
specific OSHA standards.
respirators can reduce exposure to some, but not all asthma-causing
contaminants. Under certain conditions, Moldex respirators may
be used for protection against the following contaminants:
wood dusts and grains, a Moldex disposable respirator (2200, 2300
or 2700 N series).
For metals and highly toxic asthma-causing substances, the Moldex
8000 series with 8940 or 8990 as well as the 2730N100 model.
For chemical substances such as chlorine or sulfur dioxide, the
Moldex 8000 series with appropriate chemical cartridge.
