Occupational asthma refers to cases of asthma caused by specific agents in the workplace. Occupational asthma can be further divided into two groups:Sensitizer-induced asthma - caused by sensitization (reaction) to a substance; Irritant-induced asthma (also called reactive airways dysfunction syndrome, or RADS) which is caused by one specific, high-level exposure. Although there are medical treatments that may control the symptoms of asthma, it is important to stop exposure wherever possible. If the exposure to the substance is not stopped, treatment will be needed continuously and the breathing problems may become permanent. People may continue to suffer from work-related asthma even after removal from exposure.
In 1999 Males-22.3; Females-33.7;In 2000 Males-23.7 Females-36.1; In 2001 Males-25.0 Females-37.4;In 2002 Males-25.5 Females-38.2; In 2003 Males-26.2 Females-40.6. The best way to prevent work-related asthma is to replace substances with less harmful ones. Where this is not possible, exposure should be minimized through engineering controls such as ventilation and enclosures of processes. Information on a material safety data sheet (MSDS) / safety data sheet (SDS) should list any health hazards, as well as safe handling and control steps.
