Biological exposure monitoring (BEM) is a method used to assess the level of exposure to hazardous substances in the workplace. BEM involves measuring the amount of a chemical or its metabolites in a person’s blood, urine, or other biological sample. The results obtained from the monitoring then help with determining the efficacy of existing control measures.
This method provides an accurate and objective measure of an individual’s exposure to hazardous substances, allowing for the identification of potential health risks associated with exposure. BEM is commonly used in industries where workers may be exposed to harmful chemicals or substances and is especially useful if workers have to wear significant PPE/RPE as it can be used to assess how effective the PPE is. Additionally, BEM is particularly useful if dermal (skin) absorption is a significant route of entry.
The results of BEM can help employers and employees take steps to reduce exposure to hazardous substances, such as implementing engineering controls, providing personal protective equipment, or changing work practices. BEM can also be used to evaluate the effectiveness of control measures and to ensure compliance with regulatory requirements.
Overall, biological exposure monitoring is an important tool for protecting the health and safety of workers in industries where hazardous substances are present.
