Prevention of work-related airway allergies - Recommended occupational exposure limits and periodic screening

Occupational allergic disorders are commonly reported illnesses arising from exposure to allergens. An allergic disorder is a significant problem because, if exposure continues, the symptoms may worsen and the acquired hypersensitivity may become irreversible. Hence, the consequences of allergen exposure can be far-reaching. Workers’ health should therefore be protected by managing exposure to allergens.

One of the tools available for exposure management is the application of occupational exposure limits (OELs). An OEL is the maximum permissible occupational exposure level to a given airborne substance. OELs are applied by the government and the business community.
