Lead-aware guide to renovation, home maintenance and repainting in Port Pirie. Prepared by the Environmental Health Centre, Port Pirie.
Renovators of homes in and around Port Pirie are at risk of being exposed to lead dust, paint and fumes.
Such exposure can result in an increased absorption of lead in the body.
Lead can affect anybody, but children under the age of four and pregnant women are most at risk.
Lead can affect children by causing learning and attention problems, hearing loss, slowed growth and behaviour problems.
Lead can affect adults too. Low levels of exposure can cause joint and muscle pain, high blood pressure and infertility. Higher levels (or lead poisoning) can cause memory loss and nerve problems, and very high levels can cause seizures.
Lead gets into our bodies when we breathe in lead dust or fumes in the air, or if we eat food or drink water that contains lead. Children can rapidly pick up lead through normal hand to mouth activity.
Small amounts can gradually build up in the body and cause health problems for you and your family.
Pregnant women and young children should not be present during any renovations.
Households contain fine dust which has accumulated over period of time from industrial emissions, previous renovation activities, and current dust tracked in by residents.
Ceilings, wall cavities and floor spaces will contain lead dust. All household dust contains lead and can contaminate soft furnishings (for example carpets, lounges, curtains) particularly if not removed or covered with plastic during renovation activities.
Lead dust can form when lead based paint is dry cracked, dry sanded or heated. Dust also forms when painted surfaces bump or rub together. Lead chips and dust can get on surfaces and objects that people touch. Settled lead dust can re-enter the air when people vacuum, sweep or walk through it.
Seal the area off from the rest of the house by:
Start from the top and work to the bottom by:
Use a high phosphate detergent (for example, liquid sugar soap) which will help remove lead particles during the cleaning process.
If removing old carpet, spray the surface with water to keep dust down. Roll the carpet inwards, wrap it in plastic and tape it up.
When repainting, wet sanding and wet scraping are the safest methods of preparing the surface. Do not use open-flamed torches on lead paint as they create lead fumes. If you use a heat gun, use it on the lowest setting and do not linger in one spot for too long.
When demolishing try to minimise the amount of dust created. Use water to dampen down areas and surfaces. Make sure areas are well sealed. Use barriers to contain dust. When demolition is complete apply clean fill to area.
When doing roof and ceiling work, make sure that any lead dust accumulated in roof cavities does not fall into the living areas. Remove dust in the roof cavities with a high efficiency particulate air (HEPA) vacuum cleaner.
The Environmental Health Centre loans industrial vacuum cleaners to community members for such tasks as cleaning up after renovations.
Thick plastic sheeting should be used for isolating rooms which are being renovated in order to reduce contaminated dust filtering into other parts of the house.
