The airborne concentration of a substance to which workers can be exposed day after day without adverse effect is referred to as:

The term that describes the airborne concentration of a substance to which workers can be continuously exposed without experiencing adverse health effects is known as Threshold Limit Value (TLV). TLVs are established to provide guidance on acceptable exposure limits for various hazardous substances in the workplace. These values take into account factors such as the duration of exposure and the potential for sustaining adverse effects.

TLVs are important for protecting workers’ health and are often used as a basis for regulatory actions and workplace safety programs. They help employers establish safe work practices and limit exposure to harmful substances, thereby minimizing health risks. Understanding TLVs is crucial for individuals involved in hazardous waste operations and emergency response, as they provide a standardized measure for evaluating workplace safety.
