cec, hard wiring of e-stop

[burzum]

where, if at all, in the CEC does it say that all emergency stop buttons must be hard wired. Most of my colleagues believe this is a requirement but aren't sure where to find any such rule. Please help.

It does not say anywhere in the CEC that it has to be hard wired.

Where you will find this requirement is usually during the assessment of the "Pre-Start Health & Safety Review"

The drawings would have to be submitted to the Ministry of Labour for full compliance.


“Pre-Start Health and Safety Reviews”

A Pre-Start Health and Safety Review is required if, in a factory other than a logging operation, a provision from the
regulation and the circumstances described exist,
(a) When a new apparatus, structure or protective element is to be constructed, added or installed or a
new process is to be used; or
(b) When 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 than new or modified measures are used.
3. A combination of new, existing or modified engineering controls and other new or
modified measures is used.
For the following circumstances:
I. Flammable liquids are located or dispensed in a building, room or area;
II. A process involves a risk of ignition or explosion that creates a condition of imminent hazard to a
person’s health or safety; and
III. The use of a dust collector involves a risk of ignition or explosion that creates a condition of imminent
hazard to a person’s health or safety.
If a Pre-Start Health and Safety Review is required, the owner, lessee or employer shall ensure the following:
(a) The apparatus, structure, or protective element is not operated or used, unless the review has been
conducted, and
(b) All measures identified in the review as being required for compliance with the relevant provisions of this
Regulation listed in Table 1 have been taken, and
(c) If some or all of the measures specified in (b) are not taken, the owner, lessee or employer shall provide
written notice to the joint health and safety committee or the health and safety representative, if any, of
what measures have been taken to comply with the relevant provisions of Regulation 851 that are listed in
Table 1.
A Pre-Start Health and Safety Review includes the preparation of a written report that is made to the owner, lessee or
employer and contains,
The details of the measures to be taken for compliance, and
(a) If testing is required before the apparatus or structure can be operated or used or before the process can
be used, details of measures to protect the health and safety of workers that are to be taken before the
testing is carried out.
A Pre-Start Health and Safety Review shall have the following:
(a) Date and signature, and
(b) The report bears a professional engineer seal.


All reports of Pre-Start Health and Safety reviews conducted under this Regulation shall,
(a) Be kept readily accessible in the workplace together with any supporting documents, and
(b) Be provided to the joint health and safety committee or the health and safety representative, if any, before
the apparatus, structure or protective element is operated or used or the process is used.
Drawings may still be available with classifications done by the Ontario's Ministry of Labour. In lieu of drawings
stamped by the Ministry engineers, classifications on drawings stamped by a Professional Engineer, operating under a
Certificate of Authorization issued by the Association of Professional Engineers of Ontario and based on having
submitted a Certificate of Insurance, or a Professional Engineer employed by the owner, are acceptable in accordance
with the above process. These drawings must be available at the job site. Decisions from Ministry engineers will be used
where there are disputes about a particular classification.
The electrical inspector concerned reviews the installation drawings for wiring methods in each classified area of the
plant and any safety devices such as dust collectors, ventilating equipment, etc., which might impact on the installation
methods with reference to the stamped drawings.
The electrical inspector ensures the wiring and equipment installed conforms with the requirements of each area.
How to Contact an Engineer to Perform Area Classification?
The Consulting Engineers of Ontario (CEO) will provide the necessary service and will refer qualified engineers to
perform Area Classifications. They can be reached by calling the:
general telephone number - (416) 620-1400,
fax number - (416) 620-5803, or
Email - [email protected]
The CEO's standard approach is to refer up to three consulting engineers (if available) who have the required
qualifications and experience and are situated in an appropriate geographic location.
