A risk-based approach to reducing exposure of staff to laboratory animal allergens.

Abstract

Within the biomedical research industry, people who work with laboratory animals may be at risk of developing laboratory animal allergy, which can lead to occupational asthma. Under UK and EU laws, employers must prevent or adequately control exposure to any hazardous substance, which includes animal allergens, so far as reasonably practicable, for the protection of all people on the premises. This can be achieved in part by reviewing the risk of allergen exposure in specific areas of a facility and implementing appropriate infrastructure, environmental and performance controls to minimize that risk. The authors describe the approach used at their institution to stratify risk of allergen exposure in various areas of the animal facility and to implement appropriate controls. They also discuss their use of a monitoring program to evaluate allergen concentrations in low- and high-risk areas of the animal facility and explain how the monitoring results can be applied to determine which controls are needed to minimize risk of exposure and to provide a safe working environment.
