Section 193
Disposition versions
193. Emergency stop: Any machine whose operation requires the presence of at least one worker must be equipped with an emergency stop device.
That device stops the machine, considering the machine’s design, in the shortest possible time with no additional risk. In addition, it has the following characteristics:
(1) it is easily visible and within reach of the worker;
(2) a single action activates it;
(3) it is clearly identified;
(4) it triggers or may trigger, as required, certain functions to reduce risk such as a reversal or limitation of motion;
(5) it is available and operational at all times, whatever the machine’s control or operating mode.
The resetting of the emergency stop device after it is used shall not by itself cause the machine to start up.
This section does not apply to a portable power tool or a machine for which an emergency stop device would not reduce the risk.
193. Groups of machines: Any stopping device or switch for a machine belonging to a group of machines that are wired to operate in series, including an emergency shut-off switch, shall in addition be designed to stop serial upstream and downstream machines if their operations constitute a danger for worker safety.
