S-2.1, r. 13 - Regulation respecting occupational health and safety

Section 172 Disposition versions

2023-07-27

172. Definitions: In this Division, unless otherwise indicated by context,

“automatic monitoring” means the principle that ensures that safety functions that rely on a means of protection are maintained if the ability of a component or an element to perform its function is diminished, or if the operating conditions are changed in such a way that hazards are generated. Automatic monitoring either detects a fault immediately or carries out periodic checks so that a fault is detected before the next demand upon the safety function; (autosurveillance)

“control actuator” means an element allowing an operator to control a machine, generally through pressure from the hand or foot, and in particular a push-button, lever, switch, handle, slider, stick, control wheel, pedal, keyboard or touchscreen; (organe de service)

“danger zone” means any zone situated inside or around a machine which poses a risk for the health, safety or physical well-being of workers; (zone dangereuse)

“enabling device” means an additional manually operated device used in conjunction with a start control and which, when continuously actuated, allows a machine to function; (dispositif de validation)

“fixed guard” means a guard affixed in such a manner, for example, by screws, nuts, welding, that it can only be opened or removed by the use of tools or by destruction of the affixing means; (protecteur fixe)

“guard” means a physical barrier designed as part of a machine to protect the machine’s danger zone, such as a housing, a cover, a screen, a door or a cabinet; (protecteur)

“guard with a start function” means an interlocking guard which, once it has reached its closed position, gives a command to initiate the machine function presenting a risk for worker health and safety without the use of a separate start control; (protecteur commandant la mise en marche)

“hold-to-run control device” means a control device which initiates and maintains machine functions only as long as the control actuator is activated; (dispositif de commande nécessitant un actionnement maintenu)

“interchangeable equipment” means equipment intended to be installed on a machine, for which the installation can be done by the operator, in order to change its function or attribute a new function; (équipement interchangeable)

“interchangeable tool” means a tool such as a blade, bit or excavating bucket that may be installed on a machine without altering its function or adding a new function; (outil interchangeable)

“interlocking guard” means a guard associated with an interlocking device to ensure that together with the control system of the machine, the machine functions presenting a risk for worker health and safety that the guard aims to protect from cannot operate until the guard is closed, that the closure of the guard does not by itself start those functions, and that a stop command is given if the guard is opened while such functions are operating; (protecteur avec dispositif de verrouillage)

“interlocking guard with a locking device” means a guard associated with both an interlocking and a locking device to ensure that, together with the control system of the machine, the machine functions presenting a risk for worker health and safety that the guard aims to protect from cannot operate until the guard is closed and locked, that the closure and locking of the guard do not by themselves start those functions, and that the guard remains closed and locked until the risk due to such functions has disappeared; (protecteur avec dispositif d’interverrouillage)

“limited movement device” means a control device, each actuation of which results, via the control system, in only a limited functioning of an element of the machine; (dispositif de commande de marche par à-coups)

“manually adjustable guard” means a guard that is manually adjusted and that remains fixed during an operation; (protecteur réglable manuellement)

“means of protection” means a guard or protective device; (moyen de protection)

“movable guard” means a guard that can be opened without the use of tools; the opening and closing of the guard may be power operated; (protecteur mobile)

“protective device” means a device other than a guard that eliminates or reduces risk, alone or associated with a guard; (dispositif de protection)

“safety function” means a function of a machine whose failure can result in an immediate increase of risk, with respect to a means of protection depending on a control system; (fonction de sécurité)

“safety-related part of the control system” means part of a control system that responds to safety-related input signals and generates safety-related output signals; (partie du système de commande relative à la sécurité)

“self-closing guard” means a movable guard operated by a machine element, by the workpiece or by a part of the machining jig, so that it allows the workpiece or the jig to pass and then automatically returns, for instance by means of gravity, a spring or other external power, to the closed position as soon as the opening is freed; (protecteur à fermeture automatique)

“sensitive protective equipment” means equipment for detecting a person or part of a person’s body which generates a signal to the control system to reduce risk to the persons detected, and in particular

(1)  an electrosensitive device such as an active optoelectronic protective device, including safety light curtains and laser scanners;

(2)  a pressure-sensitive device such as a mat, bar, edge or wire; (équipement de protection sensible)

“two-hand control device” means a control device which requires simultaneous actuation by both the operator’s hands in order to initiate and to maintain machine functions presenting a risk for worker health and safety. (dispositif de commande bimanuelle)

172. In this Division as well as in section 323, “danger zone” means any zone situated inside or around a machine and which poses a risk for the health, safety or physical well-being of workers.

In this Division as well as in sections 239 and 267, “protector” means the part of a machine used specifically to isolate a machine’s danger zone by means of a material barrier, such as a housing, a cover, a screen, a door or a cabinet.
