S-3.1, r. 10 - Regulation respecting safety in Alpine ski centres

Full text
7.01. Where tractor vehicles are used on an Alpine ski slope for purposes other than for grooming its surface, the operator shall comply with one of the following instructions:
(1)  he shall close the slope by posting pictograph 241 in Schedule 1 at the beginning of the slope and at each of its access points located at the same level as or uphill from the work area and by prohibiting access thereto by physical means at each of those places; or
(2)  he shall post pictograph 273 in Schedule 1 uphill from each fault in the relief and from each curve from which the tractor vehicle located downhill is not visible far enough in advance so that the skier may have the manoeuvering space required to avoid it. Pictograph 273 shall be posted at the centre of the slope and shall be removed as soon as the tractor vehicle has passed.
Instead of posting pictograph 273, the operator may ask an employee to stand at the appropriate place.
This section does not apply where tractor vehicles are used at the request of a first-aider on an Alpine ski slope to assist a person.
O.C. 1572-95, s. 2.
