WORKSAFE Victoria has issued safety guidelines for workers casting lead alloys in the manufacturing industry, warning against excessive exposure to lead.
According to WorkSafe Victoria, lead is a cumulative poison which builds up in the body over a period of time until symptoms occur.
Casting workers who are exposed to lead are at risk of kidney damage, nerve and brain damage, paralysis and lead palsy.
Exposure can occur through inhalation of lead fumes and airborne dust and ingestion from contaminated hands or food.
To reduce the risk, WorkSafe Victoria suggests using less hazardous compounds, and using thermostats to ensure the casting task is performed at the recommended pour temperature of 280°C. Higher temperatures will generate more lead fume.
Local exhaust ventilation over the melting pot can also help capture fumes generated during melting and pouring. Ventilation should also be used around the sander to capture the fine lead dust generated.
Workers may also opt to use P1 minimum respirators for sanding and buffing if ventilation is not practicable or effective. For melting or pouring, a P2 respirator is required.
