The Ontario Ministry of Labour mandates identification of a specific list of hazardous materials at all prospective construction sites. Under the Ontario Occupational Health & Safety Act, before a construction job is allowed to begin, contractors and construction workers need to be cognizant of all designated substances in the building, so they can take measures and be aware of precautions to limit their exposure.
Kleinfeldt’s Designated Substances Survey includes the sampling and analysis of site materials and substances suspected of contamination, and the preparation of inventories of those substances for the purpose of their management per stipulations and regulations.

The current list of hazardous materials is as follows:
|
- Acrylonitrile (used in industrial chemical processes)
- Arsenic (certain wood preservatives, occurs naturally in rock formations, metallurgy)
- Asbestos (old pipe insulation, old ceiling tiles)
- Benzene (solvent found in petroleum products)
- Coke oven emissions
- Ethylene oxide (used in industrial chemical processes)
|
- Isocyanates (used to produce pesticides)
- Lead (old paint and old plumbing solder)
- Mercury (found in thermometers)
- Silica (fine sand dust from concrete)
- Vinyl chloride (precursor to polymers)

Once hazardous materials have been identified, designated substances require removal, encapsulation or—depending upon the nature of the contaminant--may require a periodic remediation plan to alleviate potential liability issues.
Kleinfeldt’s Designated Substances Survey, resulting in detailed report of the findings, goes one step further: it is appended by remediation suggestions, any and all of which can be handled directly by Kleinfeldt. Removal, abatement and/or ongoing management procedures are presented, in an effort to find the most efficient economic solution to safeguard the health of site occupants. These services include air quality monitoring and documentation for the purpose of liability limitation.
