What term describes the highest level an employee can be exposed to without significant risk?

The term that accurately describes the highest level an employee can be exposed to without significant risk is the Permissible Exposure Limit. This limit is set by regulatory agencies and indicates the maximum concentration of a hazardous substance that an employee may be exposed to over a specific time period. The intent of the Permissible Exposure Limit is to protect employees from harmful effects while ensuring that their workplace environment is safe.

While the Ceiling Limit refers to exposure levels that should not be exceeded at any time during the workday, the Recommended Exposure Limit is more advisory and not enforceable by law. The Action Level serves as a trigger for additional protective measures but does not define an upper limit for safe exposure. Therefore, Permissible Exposure Limit is the most applicable term for the scenario described.
