CONTAMINANT: ASTHMA CAUSED BY OCCUPATIONAL EXPOSURE
ORIGIN: Moldex Technical Services Department
REVIEWED/UPDATED: August 2021
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.
Moldex® 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:
- For wood dusts and grains, a Moldex® disposable respirator (N Series).
- For metals and highly toxic asthma-causing substances, the Moldex® 8000 series with 8940, 8990 or the 7000 series with 7940 or 7990 as well as the 2730N100 or 2360P100 model.
- For chemical substances such as chlorine or sulfur dioxide, the Moldex® 7000, 8000 or 9000 series with appropriate chemical cartridge.
Anywhere occupational asthma is prevalent:
Work with red cedar
Grain handling industries
Snow crab and egg processing
Detergent manufacturing containing biological enzymes
Work with paint and adhesives
Work with metal salts
