Weatherproofing of roof
105(1)An employer and a contractor shall each ensure that a warning line is
(a) not less than 2 m from the unguarded edge,
(b) has a minimum diameter of 10 mm,
(c) is suspended at a height of not less than 750 mm and not more than 900 mm,
(d) is supported by corner and intermediate posts sufficient to keep the line taut, and
(e) has readily visible markers placed every 1.5 m along the length of the line.
105(2)Despite paragraph (1)(a), a warning line may be 1 m from an unguarded edge at the dump point for snow removal or when an employee is engaged in weatherproofing, provided adequate precautions are taken to ensure the safety of the employee.
105(3)An employer shall ensure that an employee who is working in the control zone uses another method of fall-protection in addition to the warning line.
105(4)When employees are engaged in weatherproofing, a safety monitor may be used as the means of fall-protection for employees working in the control zone.
105(5)The safety monitor referred to in subsection (4) shall ensure that tasks being performed in the control zone are performed in accordance with the fall-protection code of practice and in a manner that minimizes the potential for an employee to fall.
105(6)A safety monitor referred in subsection (4) shall
(a) be experienced in the work overseen and trained in the role of safety monitor,
(b) be present at all times when an employee is in the control zone,
(c) have complete authority over the work as it relates to the prevention of falls,
(d) be located so as to have a clear view of the work being performed by the employee,
(e) be able to communicate with the employees being protected without needing to yell,
(f) be instantly distinguishable from other workers,
(g) engage in no other duties while acting as the safety monitor, and
(h) monitor a maximum of eight workers.
105(7)An employer shall ensure that no employee enters the control zone unless the employee is required to do so by reason of the employee’s work duties.
105(8)The owner of a place of employment, employer and contractor shall each ensure a travel restraint system
(a) is rigged to prevent the employee from reaching an unguarded edge,
(b) is, subject to paragraph (c), attached to an anchor point capable of supporting two times the maximum load likely to be applied to it, or
(c) when it is used on a roof with a slope greater than 3 in 12, is attached to an anchor point that is capable of withstanding a 22 kN force or, if used under the direction of a competent person, four times the maximum load that may be generated in the fall-arresting system.

Weatherproofing of roof
105(1)In this section and sections 106 and 106.1
“fall-restraint system” means a mechanism
(a) that restricts the movement of an employee so that the employee is prevented from falling from the work surface, and
(b) that meets the requirements of subsection (6);
“unguarded edge” means an edge of a roof that is not guarded by a guardrail;
“warning line” means a warning line that meets the requirements of subsection (5);
“weatherproofing” means the application of tar, gravel, insulation, shingles or membrane material to a roof but does not include the installation of decking material or the stripping of materials from the roof.
105(2)Where an employee is engaged in the weatherproofing of a roof that
(a) is 3 m or more above the ground or other safe working level,
(b) has a slope of 4 in 12 or less, and
(c) has an unguarded edge,
and the employee is not using an individual fall-arresting system or a fall-restraint system, an employer shall ensure that a warning line is installed and maintained 1 m from the unguarded edge.
105(3)Where a warning line is installed under subsection (2), an employer shall ensure
(a) that an employee who is working between the warning line and the unguarded edge has been fully instructed in work procedures and hazards, and
(b) that a competent person monitors all employees who are working between the warning line and the unguarded edge.
105(4)An employer shall ensure that no employee enters the area 1 m or less from the unguarded edge of a roof described in subsection (2) unless the employee is required to do so by reason of the employee’s work duties.
105(5)A warning line shall
(a) have a minimum diameter of 13 mm,
(b) be suspended at a height of not more than 900 mm and not less than 750 mm,
(c) be supported by corner and intermediate posts sufficient to keep the line taut, and
(d) have readily visible markers placed every 1.5 m along the length of the line.
105(6)A fall-restraint system shall
(a) be rigged to allow the movement of employees only as far as the edge of the roof,
(b) be attached to a secure anchor capable of supporting the loads that may be applied to it, and

(a) where an employee is engaged in the installation or removal of a guardrail, an individual fall-arresting system or a fall-restraint system, if the employee has been fully instructed in work procedures and hazards, or
(b) where an employee is engaged in the weatherproofing of a roof that has a total area of less than 23 m2 or of a roof of a canopy or a walkway, and it is not practicable to use a guardrail, an individual fall-arresting system, a fall-restraint system or a warning line.
