183. Equivalent safety precautions: Section 182 does not apply when it is foreseeable that the effects of installing a protector or a protective device on a machine will make the operations for which it was designed reasonably impractical, such as a snow blower, a railway switch or a medical appliance intended to act directly on a patient.
In this case, the employer shall take precautions that ensure the equivalent safety of workers, namely with respect to the organization of the work, worker training, the machine’s operating conditions and operating modes, and individual protective means and equipment that take into account the absence of a protector or of a protective device.
