Section 161 Control zones
The use of a control zone is an approach to fall protection that places special requirements on workers and work being performed on a nearly level working surface within 2 metres of an unguarded edge from which a worker could fall. Control zones can be used on surfaces having a slope of up to 4 degrees measured from the horizontal.
If a worker works within 2 metres of the control zone i.e. within 4 metres of the unguarded edge, a raised warning ling or equally effective means is required. If a worker works within the control zone, then a travel restraint system must be used. A control zone cannot be used if the level working surface on which work is being performed is less than 4 metres wide. In such circumstances, one of the other methods of fall protection required by the OHS Code must be used.
Work away from unguarded edge
Situations may arise where, on a large flat roof for example, work is performed at a significant distance away from an unguarded edge e.g. at a penthouse near the centre of the roof. With the exception of when workers enter or leave the work area at an unguarded edge, workers have no contact with the edge. Upon accessing the roof, workers must proceed directly to their work area. Under such circumstances, a line defining a control zone is unnecessary, as are the remaining requirements for fall protection that would normally apply at the unguarded edge.
Line defining the control zone
If a worker works within 2 metres of the control zone i.e. within 4 metres of the unguarded edge, a raised warning line or equally effective means of alerting the worker to the unguarded edge is required (see Figure 9.25). The raised warning line or other equally effective means such as barricades must be placed at least 2 metres from the edge. The warning method provides a visual and physical reminder of the presence of the hazard.
For compliance purposes, a raised warning line can consist of ropes, wires or chains, and supporting stanchions, and should be
a. flagged or marked with highly visible materials at intervals that do not exceed 2 metres (6.5 feet),
b. rigged and supported so that the lowest point (including sag) is not less than 0.9 metres (34 inches) from the walking or working surface and its highest point is not more than 1.2 metres (45 inches) from the walking or working surface,
c. attached to each stanchion in such a way that pulling on one section of the line between stanchions will not result in slack being taken up in the adjacent section before the stanchion tips over, and
d. the rope, wire or chain must have a minimum tensile strength of 2.2 kN (500 lbs).
An “equally effective method” might be a substantial barrier e.g. pile of materials or supplies, tall parapet, building system pipes and ducts, etc. that is positioned between the worker and the unguarded edge, preventing the worker from getting to the edge. Since this substantial barrier is acting as a guardrail, it must at all time be at least 920 millimetres (36 inches) tall while the protected worker is using it.

DIVISION III.1 PROTECTION AGAINST FALLS
33.1. Cases where workers must be protected: Workers shall be protected against falls in the following cases:
(1) if they are at risk of falling more than 3 m unless they are only using a means of access or exit;
(2) if they are at risk of falling
(a) into a liquid or dangerous substance;
(b) on a moving component;
(c) on equipment or material that constitute a danger;
(d) from a height of 1,5 m or more in a well, a basin, a tank, a reservoir, a vat, a container for the storing or mixing of substances, or where the workers are handling a load.
33.2. Safety measures: Where workers must be protected in accordance with section 33.1 and subject to section 33.3, one or several of the following measures shall be taken by the employer to ensure the safety of workers:
(1) change the work position of workers so that they can work on the ground or on another surface from which they are not at risk of falling;
(2) install guardrails or a system which, by limiting the movements of workers, prevent them from being at risk of falling;
(3) use common protective devices and equipment, such as a safety net in accordance with section 354;
(4) ensure that workers wear safety harnesses secured to an anchorage system by a fall arrest connecting device, in accordance with section 347 when they are working. When workers cannot position themselves without the help of their fall arrest connecting device, ensure that they also use a means of positioning, such as a plank on brackets, a positioning tether or strap, a suspension cable or a platform;
(5) use another means that ensures equivalent safety for workers.
33.3. Installation of guardrails: Guardrails must be placed on open sides of a roof or around any area from which workers may fall:
(1) into a liquid or dangerous substance;
(2) a height of 1,5 m or more in a well, a basin, a tank, a reservoir, a vat, a container for the storing or mixing of substances, or where the workers are handling a load; or
(3) a height greater than 3 m in other cases.
354.1. Characteristics of a warning line: A warning line must be
(1) continuous and installed on all sides of the work area that it delimits;
(2) placed at a distance of 2 m or more from any place where a worker may fall from a height;
(3) made of a rigid strip, a cable or a chain able to withstand a tractive force of at least 2,22 kN;
(4) equipped with flags made of high-visibility materials and placed at intervals of not more than 2 m;
(5) capable of withstanding a load of 100 N applied horizontally at the line’s highest point or vertically at its midpoint between 2 stanchions;
(6) completed at each access point, storage area or hoisting area by a path formed by 2 parallel lines not exceeding 3 m in length. In places where the access path starts at a roof edge, a guardrail must be installed on the side of the roof, in compliance with section 33.3, so as to cover the first 3 m on either side of the access path’s starting point; and
(7) installed so that the line is
(a) located between 0,7 m above the work surface at the line’s lowest point and 1,2 m above that surface at its highest point;
(b) supported by stanchions placed at intervals of not more than 2,5 m; and
(c) attached to each stanchion so that pushing on the line between 2 stanchions does not reduce the height of the line between adjacent stanchions by an equivalent amount.
