The WEEL Committee develops guides on exposure levels for chemical and physical agents and stresses when no legal or authorative limits exist. The Committee makes appropriate recommendations about exposure levels to standards-setting bodies and updates existing WEELs as new information becomes available.
WEELs (air concentrations of agents in a healthy worker's breathing zone) and BEELs (concentrations of agents in biological media to reflect internal dose) are used to assess the potential for adverse health effects following healthy worker exposure to agents that may occur day after day for a working lifetime.
