What is lead?
Lead is a naturally occurring heavy metal often used in the manufacturing of common industrial and building materials. It is a soft, malleable metal known for its high resistance to chemical corrosion. Additionally, buildings built prior to the 1980’s may contain lead-based paints and plumbing. Lead can be found in many forms both inside homes or places of business, as well as in water, soil and the air we breathe. Lead means all variants of lead, lead alloys and lead compounds that can enter the human body through inhalation, ingestion or any other means of absorption.
Common places for lead:
In homes and workplaces: lead-based paints and plumbing in older buildings.
In transportation: It is often used in the transport and storage of a wide variety of chemicals.
In products: lead sheets, chemical liners, batteries, and cable sheathing.
What are the risks of lead?
Lead is a toxic substance and exposure can result in adverse health effects. Lead is an accumulative poison, meaning the body cannot rid itself of lead and concentrations build-up in the body each time the employee is exposed. Lead poisoning can cause damage to the brain, kidneys, liver and other vital organs. Lead exposure can occur through accidental ingestion through the lead in water or in solid form (for example paint chips), or through inhalation of airborne particulates of lead. It can cause damage to the nervous system and brain and is often a cause of impairment to both hearing and speech. While lead can be dangerous to all parties exposed, it is especially concerning to children and pregnant women. Lead exposure has the potential to stunt growth and development as well as play a role in learning and behavioural problems in young children.
