Lead paint

In Australia prior to 1970 the lead content in domestic paint was between 10% and 20%, while paint used on many commercial buildings and structures can contain up to 50% lead.

Asbestos Safety West are able to undertake two types of testing for lead paint:

• Lead check swabs can be used on-site to verify the presence of lead; however, this test is only accurate where lead levels are greater than 0.5% w/w

• Collection of paint samples for laboratory analysis to accurately determine the amount of lead in the paint, and enable development of exposure controls

Disturbance of painted surfaces during renovation by dry sanding, abrasive blast cleaning or heat gun spoil can generate lead dust.

Degraded lead paint that is chalky, flaking or peeling may represent a health risk due to inhalation or ingestion of the residue.  

Dust from renovation work can also contaminate soil, vegetation, food and external areas. Lead in any form is toxic to humans when ingested and inhaled repeatedly.

As with other hazardous substances, the Victorian OHS Regulations imposes strict duties on the employer to control workplace exposure to lead.
