Threshold Limit Values

Threshold Limit Values (TLVs) are guidelines established to indicate the maximum concentration of a substance in the air that workers can be safely exposed to over a specific time period, usually eight hours a day. They are developed by experts to protect health and safety in the workplace, based on scientific research. TLVs help employers and employees understand risk levels and implement safety measures to prevent harmful effects from exposure to chemicals or dust. TLVs are not legal limits but serve as important recommendations for maintaining a safe working environment.
