What is the threshold limit value of lead dust according to revised mines safety regulations?

The threshold limit value (TLV) of lead dust set by revised mining safety regulations is 0.2 mg/m³. This value is established to safeguard the health and safety of mine workers, as lead exposure can lead to serious health issues including neurological damage, blood pressure increases, and reproductive problems. By setting a TLV, regulatory bodies aim to minimize potential exposure to hazardous substances in the workplace, ensuring that air quality remains within safe limits for individuals working in mining environments.

A TLV of 0.2 mg/m³ strikes a balance between operational needs and the health of workers, promoting safety practices that minimize dust generation and maintaining adequate ventilation to reduce airborne lead concentrations. Monitoring and adhering to this limit is crucial in preventing long-term health risks associated with lead exposure.
