177. Choosing means of protection: A machine must be designed and manufactured in such a way as to render its danger zones inaccessible. If this is not possible, the resulting risks must be eliminated or reduced to the lowest possible level by installing at least one of the following means of protection, as the case may be:

(1)  where access to the danger zone is not required during normal operation of the machine,

(a)  a fixed guard;

(b)  a movable interlocking guard with or without a locking device;

(c)  sensitive protective equipment;

(d)  a self-closing guard;

(2)  where access to the danger zone is required during normal operation of the machine:

(a)  a movable interlocking guard with or without a locking device;

(b)  sensitive protective equipment;

(c)  a self-closing guard;

(d)  a two-hand control device;

(e)  a guard with a start function;

(f)  a manually adjustable guard.

Notwithstanding subparagraphs 1 and 2 of the first paragraph, access to a machine’s movable energy transmission elements must be protected by a fixed guard or a movable interlocking guard with or without a locking device.

Appropriate means of protection must be selected using recognized principles and methods to assess and reduce risk, such as those set out in CSA Z432, Safeguarding of Machinery, and ISO 12100, Safety of machinery — General principles for design — Risk assessment and risk reduction, and in accordance with the conditions of sections 181 to 185, where applicable.
