What does PEL refer to on a material data safety sheet?

PEL stands for Permissible Exposure Limit, which is a regulatory limit set by the Occupational Safety and Health Administration (OSHA) for the maximum amount of a hazardous substance that workers can be exposed to over a specific time period, usually an 8-hour workday. It is intended to protect workers' health by limiting their exposure to harmful chemicals. PEL values are crucial in helping employers establish safety protocols and ensure a safe working environment.
