What is the purpose of maintaining Threshold Limit Values (TLVs) in the workplace?

The purpose of maintaining Threshold Limit Values (TLVs) in the workplace is to ensure safe exposure limits to hazardous substances. TLVs are guidelines established by industrial hygienists to indicate the maximum concentration of a substance that workers can be exposed to without adverse health effects. They are designed to protect worker health and safety by providing limits that take into account various factors, such as duration of exposure and routes of entry into the body.

By adhering to TLVs, organizations can help minimize the risk of occupational diseases, injuries, or other health issues associated with exposure to harmful substances, ensuring a safer working environment. The adoption of TLVs is part of a comprehensive occupational safety and health program aimed at reducing exposure to hazardous materials.
