2.10.12. Safety harness:(1) A safety harness must comply with CAN/CSA Standard Z259.10-M90 Full Body Harnesses and be used with one of the following systems:(a) an energy absorber to which a lanyard not allowing a free fall of more than 1.2 m is fastened;
(b) a self retracting lanyard that includes an energy absorber or that is fastened thereto.
Energy absorbers must comply with CAN/CSA Standard Z259.11-M92 Shock Absorbers for Personal Fall Arrest Systems.
Lanyards must comply with CAN/CSA Standard Z259.1-95 Safety Belts and Lanyards.
Self retracting lanyards must comply with CSA Standard Z259.2-M1979 Fall-Arresting Devices, Personnel Lowering Devices, and Life Lines.
(2) The fastening point of a self retracting lanyard must be anchored to an element having a breaking strength of at least 18 kN;
(3) The fastening point of the lanyard must be fastened in one of the following manners:(a) anchored to an element having a breaking strength of at least 18 kN;
(b) attached to a rope grab in compliance with CSA Standard Z259.2-M1979 Fall-Arresting Devices, Personnel Lowering Devices, and Life Lines, fastened to a vertical life line or anchored to an element having a breaking strength of at least 18 kN;
(c) attached to a horizontal life line and anchorage system designed by a professional engineer as attested to by a plan or certificate available on the construction site;
(d) attached to a horizontal life line in compliance with the following minimum standards:i. the life line shall be a steel cable of a minimum diameter of 12 mm slackened to a minimum angle of 1 vertical to 12 horizontal, or 5° from horizontal;
ii. the span of the life line between the anchors shall not exceed 12 m;
iii. the life line shall be fastened to anchors having a breaking strength of at least 90 kN;
iv. the life line shall not be used by more than two workers at a time.
Notwithstanding the foregoing, for a worker using a flying scaffold held by 4 hoisting cables, the fastening point of the lanyard must be(a) anchored to an element of the platform with a breaking strength of at least 18 kN; or
(b) secured to a metallic cable at least 8 mm in diameter, fastened at each end and in the centre of the platform.
(4) Where there is a duckbilled snap hook on the end of the lanyard, that hook shall be fitted with a self-locking safety catch. Such safety catch is not compulsory in the case of workers assigned to the assembly of the latticework of reinforcing rods supporting a wall or pillar, if those workers use positioning equipment. In such a case, at least one of the measures provided for in subparagraphs 3 and 4 of the second paragraph of section 2.9.1 must be taken.
In this section, “positioning equipment” means a lanyard consisting of metal rings that is less than 400 mm long and equipped at one end with a duckbilled snap hook and fastened, at the other end, to a safety belt or to the safety harness worn by a worker.
(5) A vertical life line must comply with CSA Standard Z259.2-M1979 Fall-Arresting Devices, Personnel Lowering Devices, and Life Lines and must(a) be used by only one person;
(b) be shorter than 90 m;
(c) be fastened to an individual anchor having a breaking strength of at least 18 kN or attached to a horizontal life line in accordance with subparagraph c or d of subsection 3;
(d) never be brought into contact with a sharp edge.
(6) Where a worker assigned to the erection or checking of power line towers wears a safety harness, that harness must comply with CAN/CSA Standard Z259.10-M90 Full Body Harnesses and be used with one of the following systems:(a) an energy absorber to which are fastened two lanyards including one that must be attached at all times;
(b) an energy absorber to which is fastened one lanyard attached by a rope grab to a vertical life line;
(c) a self retracting lanyard equipped with an energy absorber or fastened thereto.
