182. Guard with a start function: A guard with a start function may be used as a means of protection when the cycle time of the machine is short and

(1)  the guard with a start function is designed and installed in accordance with the trade practice applicable to interlocking guards such as ISO Standard 14119 Safety of machinery — Interlocking devices associated with guards — Principles for design and selection;

(2)  the maximum opening time of the guard is preset to a low value, for example, equal to the cycle time, and, when that time is exceeded, the function presenting a risk for worker health and safety cannot be initiated by the closing of the guard with a start function and the cycle must be initiated only by voluntary actuation of a start control;

(3)  the dimensions or shape of the machine do not allow a person, or part of a person’s body, to stay in the danger zone or between the danger zone and the guard while the guard is closed;

(4)  all other guards for the danger zone are interlocking guards;

(5)  the interlocking guard associated with the guard with a start function is designed in a manner that its failure cannot lead to an unintended or unexpected start-up of the machine, in particular through the duplication of position sensors or the use of automatic monitoring;

(6)  the guard is securely held open, for example, by a spring or counterweight, in a manner that it can be closed only by a voluntary action by the worker;

(7)  the guard with a start function and the associated control system must comply with higher safety-related performance than under normal conditions.
