    The Occupational Health and Safety Act (OHSA) establishes the rights and duties of all parties within the workplace with the focus being the protection of workers from injury while on the job. The Ontario Ministry of Labour (MOL) is the government authority that enforces the OHSA when compliance has not been achieved through the internal responsibility of an employer. This mandate for the ministry involves a wide range of business sectors that cover the majority of Ontario workplaces. Application of the Act to such an extensive group of workplaces is addressed by the specific regulations established by the Ontario government.

    Regulation 851 was developed to address the issues specific to all industrial establishments such as factories, offices, arenas, or shops operating within Ontario. It is for this reason that Regulation 851 covers a broad range of requirements on topics such as industrial hygiene, machine guarding, fire prevention, confined spaces, equipment maintenance, material handling, and protective equipment. Certain Sections of Regulation 851 require the preparation of a written report to provide a permanent record regarding the occurrence of health & safety issues. In particular, Section 7 requires preparation of a written report detailing the measures that must be taken for compliance with the relevant provisions listed in the Table1. These reports are referred to as "Pre-start Health & Safety Reviews" and their application as described in the regulation is as follows:

    The Act reads:

    A pre-start health and safety review is required if, in a factory other than a logging operation, a provision of this Regulation listed in the Table applies and the circumstances described in the Table will exist,
    1. because a new apparatus, structure or protective element is to constructed, added or installed or a new process is to be used; or
    2. because an existing apparatus, structure, protective element or process is to be modified and one of the following steps must be taken to obtain compliance with the applicable provision:
      1. New or modified engineering controls are used.
      2. Other new or modified measures are used.
      3. A combination of new, existing or modified engineering controls and other new or modified measures is used.
