An occupational exposure limit is an upper limit on the acceptable concentration of a hazardous substance in workplace air for a particular material or class of materials. It is typically set by competent national authorities and enforced by legislation to protect occupational safety and health .
The Hierarchy of Occupational Exposure Limits, of which occupational exposure banding is a member. Occupational exposure banding, also known as hazard banding, is a process intended to quickly and accurately assign chemicals into specific categories (bands), each corresponding to a range of exposure concentrations designed to protect worker health.
The exposure assessment is initiated by selecting the appropriate exposure limit averaging time and "decision statistic" for the agent. Typically the statistic for deciding acceptable exposure is chosen to be the majority (90%, 95% or 99%) of all exposures to be below the selected occupational exposure limit.
Chemical warfare agents have extremely low occupational exposure limits that are below the sensitivity threshold for most typical monitoring methods, and often require specialized equipment. For biological agents , some methods can determine if a suspect material is of biological origin without identifying it, while identification requires ...
The anticipate, recognize, evaluate, control, and confirm (ARECC) decision-making framework began as recognize, evaluate, and control.In 1994 then-president of the American Industrial Hygiene Association (AIHA) Harry Ettinger added the anticipate step to formally convey the duty and opportunity of the worker protection community to proactively apply its growing body of knowledge and experience ...
Requests should also be made when employees are exposed to a new hazard or a hazard unregulated by OSHA or when employees are experiencing ill health when their exposure to an agent is below the occupational exposure limits. If multiple hazardous agents or conditions are present in the workplace, an HHE request can be beneficial.
Control banding is a qualitative or semi-quantitative risk assessment and management approach to promoting occupational health and safety.It is intended to minimize worker exposures to hazardous chemicals and other risk factors in the workplace and to help small businesses by providing an easy-to-understand, practical approach to controlling hazardous exposures at work.
National Institute for Occupational Safety and Health (NIOSH) RELs are designed to protect the health and well-being of workers by recommending safe exposure levels. To really use these guidelines well, safety professionals need to understand the recommended exposure levels, how to measure them, and ways to make sure workers aren't exposed to harmful stuff.
