Ontario Regulation 851 - Industrial Establishments

Regulation 851 was developed and subsequently implemented to address specific issues that are unique to many industrial establishments, such as factories, offices, and/or shops operating within the province of Ontario. Because there are so many facilities that have distinctive, specialized requirements, Regulation 851 covers a broad range of topics including industrial hygiene, machine guarding, fire prevention, confined spaces, equipment maintenance, material handling, and protective equipment among others.

Machine Guarding –
Regulation 851, Sections 24 - 42

Guards are designed to restrict access to moving parts and motors that may endanger the safety of a worker. When required, ensure that the proper guard has been installed on all equipment. Guards must comply with specific standards to adequately protect against inherent risks from the equipment and its use. You may be able to obtain proper guards from the company who constructed or sold this equipment; however, for older equipment with no guards available, there are two options: (1) buy new equipment or (2) request a Certified Safety Engineer to conduct a Pre-Start Review of your equipment (see Section 7 of Regulation 851).


Burns –
Regulation 851, Section 84; Regulation 860

Burns can be a very serious matter, and come in many different forms – chemical, friction, temperature and steam/gas. Along with various physical limitations resulting from burns, they can also become infected if not properly treated. As section 84 of Regulation 851 states - "a worker exposed to noxious gas, liquid, fume or dust; a sharp or jagged object; hot objects and molten metal; or radiant heat shall be protected by wearing the appropriate apparel to protect the worker from the hazard; or providing adequate barriers". See Section 84 for more information.

Example of protection against steam.

Lifting Devices –
Regulation 851, Sections 51 - 66; CSA Standard B167-96 & Z150-98

Inspect your lifting device before use – looking for defects, signs of extreme use etc. Ensure that any equipment being used is certified (as recommended by the manufacturer or at least once a year by a competent person) and that ALL people using the equipment be trained with their training records kept and filed. Also, please provide a list of all lifting devices to the Office of Risk Management, Environmental Health & Safety. For more information, please see the Safety Sheet and Sections 51 - 66.

Storage of Compressed Gas –
Regulation 851, Section 49

Compressed gases exist in several day-to-day forms; including many household products. Storage, transportation and use are key elements regarding industrial-sized compressed gas cylinders. When handling compressed gas cylinders (when in use and while transporting), ensure that they are properly secured so they will not fall down and/or become damaged. See section 49 for more information.


Guardrails –
Regulation 851, Section 13

There are certain instances where guardrails are required by law; the legislation states, for example, that a guard is required for an open walkway, mezzanine or platform; and around a machine that may endanger the safety of a worker. See section 13 for more information.


Grinders –
Regulation 851, Sections 29 & 30

For grinding machines used by workers, ensure that they are properly guarded and are only used by competent persons wearing the appropriate personal protective equipment (for more information, see the Safety Sheet on Grinders and Sections 29 & 30 of Regulation 851).

A Competent Person is a person who (i) is qualified because of knowledge, training and experience to organize the work and its performance; (ii) is familiar with this Act and the regulations that apply to the work and (iii) has knowledge of any potential or actual danger to health & safety in the workplace
