WorkSafe reminds professionals and home renovators about controlling risks when removing lead-based paint.
Lead-based paint was commonly used on pre-1970s buildings and structures and can contain lead levels greater than 1% dry weight. Undertaking work that involves sanding, buffing or removing paint with lead at those levels is regulated under Part 4.3 of the OHS Regulations as a ‘lead process’, therefore imposing specific employer duties.
WorkSafe has identified that some employers and self-employed persons are undertaking this type of hazardous activities with taking the appropriate precautions.
Lead can remain in your bones for years after exposure, without causing immediate health effects, although exposure at high levels can increase the risk of, and cause, long-term health issues.
Women in particular should minimise exposure as lead stored in the bones can be released into the bloodstream at times such as pregnancy, potentially leading to risk to the developing child.
There is also a high risk of children ingesting lead in environments where contamination (paint chips or dust) is not adequately cleaned up and the area decontaminated.
Employers must control lead exposure risks using a hierarchy of control. They should first try to eliminate the risk. If that’s not possible, they should reduce it by:
- Substituting a dry removal process for a wet method such as chemical paint stripping products or power tools fitted with on tool water suppression. Note: The SDS for the chemical stripping product must be reviewed and controls implemented accordingly
- Building an enclosure, where practicable, to isolate the lead-based paint removal area
- Using powered tools fitted with dust extraction systems attached to a Class M or H vacuum cleaner to minimise the generation of airborne dust.
- Ensure workers are trained in the correct removal techniques (including maintaining dust extraction systems and PPE)
- Rotating employees working in the lead-based paint removal area to reduce exposure time
- Cleaning the lead-paint removal area, using cleaning methods that do not create additional risks
- Ensuring adequate hygiene facilities, such as a designated decontamination area and wash facilities, are available
- Providing respiratory protection that is appropriate for the level of contamination, disposable coveralls, gloves and impervious safety shoes
