Lead exposure resulting from the disturbance of lead paint is becoming a prominent safety concern in renovations, construction and demolition. Whenever renovating an older building, lead exposure is a potential risk. Lead exposure has been linked to an array of ailments, ranging from developmental disorders to hearing loss. Young children living in older homes or low-income areas are at greatest risk and are most commonly exposed through dust from lead-based paint.
The widespread use of very high lead content paint (up to 5000mg/kg) was common until 1976. In 1977, the intentional addition of lead to consumer paints was prohibited in the United States with the maximum set at 600mg/kg. Canada voluntarily adopted this value in 1991 for all Canadian produced consumer paints. The Surface Coating Materials Regulations made this official in 2005. The variation in years and legislation makes it critical to test any paint before completing a renovation or any demolition in Ontario.
An estimated 37% of commercial buildings, schools and houses in Canada have lead based paints both inside and outside. In addition, lead is found in plumbing, water faucets, ceramic pottery glaze and crystal. The equivalent of 3 grains of sugar in lead dust ingested daily for a period of a couple of months can be toxic for a child.
