Warning line standards

Control zone

Source:Alberta Occupational Health and Safety Code 2009

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.

“Section 3.2.4 Maintenance and arrangement of the work site

3.2.4. Traffic lanes, passages and any work site in general shall:

(i) have no opening at floor or roof level, unless the opening is surrounded by guard-rails or closed by a load resistant cover for any loads to which it may be subjected, but not less than 2.4 kN/m2. If the cover or guard-rails interfere with the carrying out of the work, the cover or the guard-rails may be removed and replaced, for the duration of the work, by installing a continuous barrier or trestles of a minimum height of 0.7 m, at a distance varying between 0.9 m and 1.2 m from the opening, or a warning line complying with the requirements in section 2.9.4.1.”

“Section 33.3

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.

Despite the foregoing, the guardrail may be removed during the time of the work if it prevents the carrying out of a task that could not be reasonably performed otherwise. In such a case, workers must wear a safety harness secured to an anchorage system by a fall arrest connecting device, in accordance with section 347. The work area must then be delimited in particular by a continuous barrier or trestles of a minimum height of 0,7 m, located at a distance varying between 0,9 m and 1,2 m from the place where workers are at risk of falling, or by a warning line complying with the requirements of section 354.1, so as to prevent access thereto by persons not working therein.

Section 33.5

33.5. Warning line instead of a guardrail: Despite section 33.3, during roofing work, a warning line complying with section 354.1 may be installed to replace the use of a guardrail and delimit a work area on a roof with a slope equal to or less than 15° (3/12).

In such a case, another recognized protection mechanism against falls, such as a safety harness secured to an anchorage system by a fall arrest connecting device in accordance with section 347 shall be used outside the area delimited by the warning line.

  1. Machines, machine rooms or service platforms for these machines, which constitute a work station, shall, if they are situated above or below a floor and if they are not serviced by a stairway, be accessible by a service stairway, an access ramp or a fixed ladder.

However, access to such a place by means of a fixed ladder is prohibited when a worker cannot use both hands for holding onto the side rails or rungs of the permanent ladder.

This section does not apply to a vehicle.

Section 22 Service stairs

  1. Any service stairs shall:

(1) have a minimum width of 550 millimetres for stairways built or modified starting on the date this regulation comes into force;

(2) have a slope between at least 20 ° and at most 50 ° with the horizontal, except for stairways installed before January 1, 1973 which may have a slope up to 60 °;

(3) be provided with guardrails securely fastened and supported on the open sides, including landings;

(4) be provided with steps having:

(a) a uniform depth and width in any one flight;

(b) a depth of at least 150 millimetres (nose excluded);

(c) a maximum height of 240 millimetres, except for stairs built before January 1, 1973 for which the stair height may reach 280 millimetres;

(5) have a free space of at least 2 metres above each stair, measured from the nose or the forward part of the stair.

The depth of stairs on circular or spiral service stairs shall measure 230 millimetres from the post or the supports for the inside railing.

Subparagraph 5) of the first paragraph only applies to stairs built, installed or modified starting on the date of the coming into force of this regulation and whose construction, installation or modification does not require a modification of the existing building structure. Stairs that do not have to comply with subparagraph 5) shall have an adequate warning sign.

Section 23 Permanent ladders

  1. Permanent ladders used to replace service stairs shall:

(1) be of safe construction and solidly anchored to withstand a mass of 90 kilograms at the centre of the rungs with a safety factor of 4;

(2) for ladders exceeding 9 metres, have rest platforms equipped with guardrails, at least at 6-metre intervals;

(3) have a space behind the rungs of at least 150 millimetres;

(4) have a free space on each side of at least 375 millimetres and forward of at least 800 millimetres, measured from the centre of a rung;

(5) extend 900 millimetres beyond the top storey;

(6) be provided with guardrails surrounding the floor opening with a removable gate for access to the ladder;

(7) be provided with a fall arrestor in compliance with CSA Standard Z259.2.5 Fall Arresters and Vertical Lifelines, or CSA Standard Z259.2.4 Fall Arresters and Vertical Rigid Rails where there is danger of a fall greater than 6 m.

Subparagraphs 3) and 4) of the first paragraph only applies to permanent ladders built, installed or modified starting on the date of the coming into force of this regulation.

Despite subparagraph 7, permanent ladders installed before 3 January 2019 may, until they are modified, be provided with crinolines, cages or a fall arrestor in compliance with CAN/CSA Standard Z259.2.1-98 Fall Arresters, Vertical Lifelines and Rails, where there is danger of a fall greater than 6 m.

Section 24 Exception

  1. Notwithstanding subparagraph 2) of section 23, the fixed ladders servicing elevated towers, water reservoirs or other elevated constructions to which workers only occasionally have access, may be exempt from rest platforms.”
