Ingresos ordinarios

competent in fall protection equipment application, care, use, maintenance, and limitations. The training shall be conducted by a qualified trainer. Recom-mended Fall Protection training is OSSA Certified (OIL SANDS SAFETY ASSOCIATION) as this training is currently the best industry practice train-ing for oil and gas.

Working at Heights

4.2 Any worker responsible for performing rescue activi-ties must be trained in the proper techniques for the rescue system.

4.3 Training or retraining is necessary when an employer has a reason to believe a worker does not have the necessary understanding and/or skill required.

5.0 Scope of Expectations

5.1 General:

- All workers must ensure that a fall protection system is utilized when work is to be conducted at height’s that are:

o At or greater than 2 meters, or

o At a height less than 2 meters if there is an unusual possibility of injury from a fall - Acceptable fall protection can be provided by

permanent, temporary, or personal CAN/CSA approved fall protection equipment systems.

- Fall protection system is identified as:

o A personal fall arrest system o A travel/fall restraint system

o A safety net o A control zone, or

o Another system approved by a Director of Inspection

Note: An employer’s first choice should require the use of adequate guardrails to protect personnel. The guardrail must meet the design requirements listed in AB OH&S section 315 or, an OH&S approved travel restraint system to prevent a worker from reaching an edge from which the worker could fall.

Working at Heights

5.1.1 When Personal Fall protection Equipment is utilized, personnel must wear a CAN/

CSA approved full body harness. (CSA Standard Z259.10- M90)

5.1.2 When Personal Fall Protection Equipment is used, these systems must be attached properly to engineer approved anchor points with an ultimate load capacity of at least 22.2 kn. (5000 pounds) per person in any direction the load can be applied, or twice the maximum arrest force. Anchor points used for the attachment of personal fall protection equipment must be inde-pendent of any anchorage being used to support, suspend, or lift platforms or loads.

5.1.3 All Personal Fall Protection Equipment must be connected and used in accordance with manufacturer’s specifications and instructions.

5.1.4 Personal fall arrest systems will be rigged to minimize the free fall distance to less than 2 meters or the manufactures specification with a shock absorber and, 1.2 m without a shock absorber when added distance of an extended shock absorber creates a greater risk. The deceleration force will not exceed 8 Kn and the personal fall protection

system must allow for an unobstructed fall.

5.2 Permanent & Temporary Platforms

A written fall protection plan is required as part of the risk assessment/pre-job task analysis for working at heights of 1.2 meters or greater from a permanent work platform or 2 meters and greater from a temporary work area., or if a worker could fall less than 1.2 meters and there is an unusual possibility of injury because of additional hazards.

5.3 Lifts

A fall restraint system is required when conducting work at heights greater than 2 meters from Scissor lifts, vertical aerial platforms, or Boomed Genie lifts if the platform being using is operated on firm, substantially level surface with the entire manufacturer’s guardrails and chains in place and meet Alberta OH&S Sec 315. However, if the manufacturer’s specifications require the use of a fall arrest system when the vertical aerial platform is being used, then the manufacturer’s specifications take precedence and must be followed. An effective written Emergency Response Pro-cedure using task hazard analysis / risk assessment must be developed as part of the Fall Protection Plan as an alternate to mechanical lift equipment failure.

5.4 Boomed Lifts

A worker working from a boomed Arial Platform or Genie lift shall be protected from falling by using a personal fall arrest system consisting of full body harness and shock absorbing lanyard meeting CSA requirements and a manufacturer engineered anchor point. The lanyard if at all possible should be the length to prevent the worker from being ejected from the platform but not restrict their work or compromise the function of the fall arrest system. (CSA Z259.10 M90 & CSA Z259.11-M92)

5.5 Man baskets

Under normal circumstances, a worker working from a man basket shall be protected from falling by using a fall arrest system such as a vertical lifeline and rope grab combination or a self-retracting lifeline. The lifeline shall be secured to an anchor point on the boom of the crane from which the man basket is suspended. In the event that it is impracticable to provide a personal fall arrest system for one or more workers in a man basket, Alberta OH&S section 350 requires that:

Working at Heights

• A separate man basket support be attached between the suspended man basket and the hoist line above the hook assembly and

• each worker within the man basket wears a full body harness with lanyard securely attached to the man basket

• The separate or secondary man basket support, in combination with worker attachment to the man basket, functions as a fall arrest system. To limit a fall distance and the arresting force experienced by a falling worker, the secondary man basket support must be as short as possible • An effective written Emergency Response Pro cedure using task hazard analysis / risk assess

ment must be developed as part of the Fall Protection Plan as an alternate to Man basket
