Asthma Caused By Occupational Exposure

ORIGIN: Moldex Technical Services Department


Asthma is a condition 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 asthma.

Some of these substances cause sensitization, meaning only minor subsequent exposure will cause an asthmatic condition. Other substances are non-sensitizing and require a full dose for an asthmatic condition to result. Only a few of these substances have OSHA Permissible Exposure Limits (PEL) and/or specific OSHA standards.

Although respiratory protection may be used to help prevent occupationally-induced asthma, anyone who has an asthmatic condition should seek medical advice before using any respiratory devices.
