Lead is indeed a hazardous substance recognized under the Occupational Health and Safety Act, and its presence on a property can pose significant health risks, particularly concerning lead poisoning. This can have deleterious effects on human health, especially in children, leading to cognitive and developmental issues. The legislation aims to protect individuals from exposure to such toxins in various environments, including residential, commercial, and industrial settings.

The other substances listed, while also hazardous, may not be as directly associated with the specific definitions or categories outlined within the Occupational Health and Safety Act. For instance, benzene is a known carcinogen to which workers may be exposed in certain industries, and mould can cause health issues, particularly respiratory problems. Urea Formaldehyde Foam Insulation, PCBs, and asbestos are also hazardous but might relate more to environmental protection and building regulations rather than the direct occupational health focus established by the Act. Each of these substances has its guidelines and safety measures but identifying lead specifically underscores its prominence and critical nature in occupational health concerns.
