Prior to planned renovation, demolition, or construction of an establishment, a Designated Substance Survey (DSS) is required to be conducted in compliance with the Ontario Occupational Health and Safety Act (OHSA). The OHSA and the ministry of labour stipulates that the presence of certain substances which deemed to be potentially dangerous to the workers and general public, be identified first, to allow construction workers to take precautionary measures in minimizing their exposure to these substances. Briefly, the designated substances in Ontario are the following: acrylonitrile, arsenic, asbestos, benzene, coke oven emissions, ethylene oxide, isocyanates, lead, mercury, silica, and vinyl chloride. The DSS report includes a thorough assessment of the presence, locations, and concentration amount of these designated substances in a construction or demolition site. With the right information on hand about these substances, the contractors will be able to take all the necessary measures to ensure the utmost safety and protection of their workers on site and the general public as well. In addition, the DSS report aids contractors and property owners alike to prepare well and avoid any unnecessary liabilities and compensation which may be incurred from getting exposed to these harmful substances.
Given the utmost significance of having a DSS for any construction, renovation, or demolition project, it is also important to get only trained and certified site inspectors who can conduct the Designated Substance Survey in the most professional manner possible. In Etobicoke, East York, Toronto, Mississauga, Oakville, Burlington, Hamilton, and the rest of GTA, the Inch by Inch Healthy Homes has been at the forefront in conducting Designated Substance Surveys using sophisticated diagnostic equipment. Our certified building inspectors are all highly skilled and well-knowledgeable and thus, the observations and testing we do are guaranteed to be accurate and comprehensive. All the necessary information about the designated substances and their corresponding analysis in terms of their presence, location, and concentration amounts in the building site are included in the DSS report.
