5 WHAT IS A CODE OF PRACTICE? WSCC codes of practice provide practical guidance to achieve the safety standard requirements of the Northwest Territories and Nunavut Safety Acts and related regulations. As per subsection 18(3) of the Northwest Territories and Nunavut Safety Acts, For the purpose of providing practical guidance with respect to the requirements of any provision of this Act or the regulations, the Chief Safety Officer may approve and issue such codes of practice as he or she considers are suitable for that purpose. WSCC codes of practice apply to all workplaces in the Northwest Territories and Nunavut. Codes of practice are approved by the Northwest Territories and Nunavut s Chief Safety Officer for use by all occupational health and safety (OHS) stakeholders. Codes of practice come into effect in each territory on the day they are published in the Northwest Territories Gazette and Nunavut Gazette, respectively. Codes of practice do not have the same legal force as the Safety Acts and related regulations. A person or employer cannot be prosecuted for failing to comply with a code of practice. However, in legal proceedings under the Safety Acts and related regulations, failure to observe a code of practice may be a consideration when determining whether a worker or employer complies with the Safety Acts and related regulations. Employers and workers should follow WSCC codes of practice unless there is an alternative course of action that achieves the same or better occupational health and safety outcomes. A Code of Practice Provides practical guidelines. Needs to be adapted to the work site. May be used as evidence. Should be followed unless there s a better way. 1

6 INTRODUCTION The Personal Protective Equipment Fall Protection code of practice provides basic guidelines to ensure worker safety in the workplace through the use of personal protective equipment (PPE) in the form of fall protection. The General Safety Regulations require the use of fall protection PPE when working at an elevation of 3 m (10 ft.) or more. The code of practice provides clarity about regulatory requirements, applicable CSA standards and overall information about fall protection. Definition Personal Protective Equipment means clothing, a device or other article required to be worn or used by a worker to prevent injury. Falls are the number one cause of accidental death in construction. A worker does not have to fall far to be injured or killed. If a worker is at risk of falling any distance, fall protection measures need to be in place. PPE is equipment worn by workers to minimize exposure to specific occupational hazards. PPE cannot eliminate a hazard, but can reduce the risk of injury. Fall protection PPE including but not limited to travel-restraint systems, fall-restricting systems, fall-arrest systems or safety nets, decrease the risk of injury to workers. 2

7 PPE AND HAZARD CONTROL Decisions about PPE form part of the hazard assessment process, the standard work site approach to dealing with potential hazards. There are five basics ways to control hazards. These controls form a hierarchy. Elimination is always the first control to consider. After that, proceed down the hierarchy until the control of last resort, PPE. The five basic ways to control hazards and examples: 1. Elimination (remove from the work site) 2. Substitution (use a less harmful chemical) 3. Engineering (isolate equipment/set guards) 4. Administration (provide training/maintenance) 5. Personal Protective Equipment (provide gloves/goggles) The use of PPE does not prevent accidents or eliminate hazards. Make every effort to control all hazards at the source. Training is also important. PPE cannot achieve its fullprotection potential without worker knowledge and cooperation. Several controls may have to be put in place. Certain hazards may require multiple PPE solutions. For example, working with chlorine requires respiratory and eye protection because chlorine irritates both the respiratory system and the mucous membranes of the eyes. Wearing PPE should not add to the hazard or create a new hazard. For instance, proper glove selection can prevent skin damage, but gloves worn while working with moving equipment can create an entanglement hazard. Using different types of protection at the same time, i.e. hard hat, ear muffs and goggles, should not increase the risk to the worker. PPE design criteria cannot cover all eventualities. Do not use PPE when its use creates hazards greater than those for which it is designed. Take uncertainties into account when evaluating potential hazards.

8 REGULATORY REQUIREMENTS The Northwest Territories and Nunavut General Safety Regulations identify when to use PPE fall protection. Northwest Territories and Nunavut GENERAL SAFETY REGULATIONS Safety-belts, Body Harnesses, Lanyards and Lifelines 57. (1) A worker shall wear a lanyard, lifeline and safety-belt or body harness where that worker is working (a) at an elevation of 3 m (10 ft.) or more above grade or flood level, (b) over a pit, a shaft, or operating machinery, or (c) where a fall could result in his or her drowning, and where it is impracticable to provide adequate work platforms or guarding. (2) An employer shall provide a separate lanyard, lifeline and safety-belt or body harness to each worker to whom the conditions specified in subsection (1) apply. (3) Subsection (1) does not apply (a) to structural steel erectors or similar tradespersons who are experienced at working at heights and where the use of a safety-belt, body harness, lanyard or lifeline may produce an additional hazard; or (b) where a protection approved by the Chief Safety Officer or a safety net has been provided. 58. An employer shall ensure that (a) safety-belts, body harnesses and lanyards used by a worker comply with the following standards, as amended from time to time, of the Canadian Standards Association: (i) CAN/CSA-Z , Safety Belts and Lanyards; (ii) Z259.2-M1979, Fall-Arresting Devices, Personnel Lowering Devices, and Life Lines; (iii) CAN/CSA-Z M90, Full Body Harness; (iv) CAN/CSA-Z M92, Shock Absorbers for Personal Fall Arrest Systems; (b) a lifeline or lanyard is protected by padding where it passes over sharp edges; (c) a lifeline is (i) free of knots of splices except at its terminals, (ii) not attached to the same anchor points as the suspension lines of a work platform, and (iii) attached to a fixed anchor capable of supporting twice the shock load that may be applied; (d) a safety-belt, body harness, lanyard or lifeline is assembled and used in a manner that will limit the free fall of a worker to 1.25 m (4.1 ft.); (e) metal parts of, or hardware attached to, a safety-belt, body harness, lanyard or lifeline are of drawn, rolled or forged metal with a load arresting capacity of not less than 17.8 kn (4,000 lbf); 4

A worker shall ensure that (a) subject to this section, where he or she is using tools that may sever, abrade or burn a lifeline, he or she uses wire rope or wire corded fibre rope; (b) where he or she is working near energized electrical circuits where a conductive lifeline cannot be used, he or she uses two non-conductive lifelines; and (c) where he or she is working on a communications or power transmission tower he or she (i) uses a lanyard and safety-belt or body harness, and (ii) is secured to the tower when working or resting. Refer to all current CSA Z259 Standards for Personal Fall Protection Equipment. CSA STANDARDS The Canadian Standards Association (CSA) develops standards to address needs such as enhancing health and safety. To view CSA standards online see CSA Group test and certify products to Canadian standards and issue the CSA Mark for qualified products. In the Northwest Territories and Nunavut General Safety Regulations, a CSA reference is written as follows: 58. An employer shall ensure that (a) safety-belts, body harnesses and lanyards used by a worker comply with the following standards, as amended from time to time, of the Canadian Standards Association: (i) CAN/CSA-Z , Safety Belts and Lanyards; 5

10 CAN/CSA-Z CAN/CSA Stands for Canada and the Canadian Standards Association. Z259.1 Lettering between CAN/CSA and the last two digits represent the internal CSA coding of the relevant standard. -95 The last two digits indicate the year issued. Standards are updated due to technological and research developments on the subject. When updates to standards occur, the end of the CSA reference changes. The current standard is CAN/CSA-Z This shows that the standard was amended in According to the Northwest Territories and Nunavut regulations, the most recent standard applies.

11 HOW LONG DOES IT TAKE TO FALL? Many workers believe that they have time to regain their balance before they fall this is not always true. The following table indicates how far you can fall in just a few seconds: You may not have time to grab hold of something safe, but you can still prevent a tragedy. Properly maintained and worn, a safety belt or full body harness attached to a secure anchor could save your life. FALL RESTRAINT OR FALL ARREST? Fall restraint systems prevent you from falling. Examples include: Work-positioning systems using either safety belts or full body harnesses that attach you to an anchor and leave both your hands free to work Travel-restriction systems of guardrails or personal fall protection equipment used to prevent you from travelling to an edge from where you may fall Fall arrest systems protect you after you fall by stopping the fall before you hit the surface below. Examples include: Full body harnesses connected by lanyards or lifelines to secure anchors Safety nets In choosing a fall protection system, you should first consider installing guardrails or barriers. They provide a high degree of protection once installed properly. However, installing guardrails or barriers at a work site is not always practical that is when you may need personal fall protection equipment. 7

12 WRITTEN FALL PROTECTION PLAN A written fall protection plan is required prior to using a personal fall protection system for work with a potential fall hazard of 7.5m (25 ft.) or more. The written plan should identify: Potential fall hazards on the job Types of fall protection systems to be used Instructions to workers on how to safely use the equipment, and Instructions on how to rescue a worker who has fallen and can t initiate self-rescue SAFETY BELTS When to use a safety belt You must never wear a safety belt in a fall arrest situation. If you fall into a safety belt, you could still suffer severe back and abdominal injuries. Restrict the use of safety belts to fall restraint systems only. If there s a chance you could fall, install guardrails or wear a full body harness in a properly configured personal fall protection system. Inspecting your safety belt Inspect your safety belt before each use. Check the buckle, the webbing, the D-rings, and the manufacturer s label for additional user information. If the belt is damaged or worn, do not wear it. Note: A safety belt that meets the CSA Standard Z259.1 is acceptable to the WSCC. Buckle Make sure the buckle s tongue overlaps the buckle frame, moves freely, and is not bent or worn down. Check the roller to make sure it turns freely on the buckle frame. 8

13 Webbing Look for frayed, cracked, cut, burned or otherwise damaged webbing. D-rings Check to see whether D-rings are bent, cracked, nicked, or gouged. Do not use safety belts that show signs of damage. Manufacturer s label Inspect the manufacturer s label on belt. The manufacturer s label on a CSA-approved safety belt will contain the following information: Manufacturer or vendor identification Belt s waist size Material the belt is made of Date the belt was manufactured Model number Warning not to be used for fall arresting the Putting on a safety belt Before putting the belt on, make sure you have the right size. Fasten the belt snugly around your waist. Wear it high on your waist, not low around the hips or pelvic area. Position the belt buckle at the front of your body, and make sure the belt tail is secure in the belt loop and not hanging out loosely. 9

14 FULL BODY HARNESSES When to use a full body harness When using personal fall protection equipment, wear a full body harness if you are at risk of falling. A full body harness consists of straps passed over the shoulders, across the chest, and around the legs. In a fall, a full body harness protects you more than a safety belt, because it distributes the force of impact over a greater area of your body. Using the right full body harness A full body harness designed to arrest falls should have A back-mounted D-ring located between the shoulder blades The letter A stenciled on each shoulder strap below the D-ring An arrow stenciled above each letter A pointing up at the D-ring The arrows on the shoulder straps point to the only D-ring on the harness designed to safety arrest a fall. This is a full body harness worn to arrest falls. Note that the D-ring is located between the shoulder blades. Inspecting your full body harness Inspect your harness before each use. Check the buckles, the webbing, the D-rings, and the manufacturer s label for additional user information. If the harness is damaged or worn, do not wear it. 10

15 Buckles Many full body harnesses have interlocking buckles called friction buckles. Look for bent, cracked, or nicked buckles. Test the buckles to make sure the coupling is secure. Webbing Look for frayed, cracked, cut, burned, or damaged webbing, and loose or broken stitching. D-rings Look for bent, cracked, nicked, or gouged rings. Manufacturer s label Inspect the manufacturer s label on the harness. The manufacturer s label on a CSAapproved full body harness will contain the following information: Manufacturer or vendor identification Size of the harness Date the harness was manufactured Model number Some harnesses are designed to serve more than one purpose. Check the manufacturer s label for the harness s classification. Group A Fall arresting Group D Controlled descent Group E Confined entry (raising and lowering) Group L Ladder climbing Group P Work positioning Note: A full body harness that meets the CSA Standard Z is acceptable to the WSCC. Putting on a full body harness Adjust all hardware and straps so the harness fits snugly, but still lets you move freely. Tuck in all loose straps so they don t snag or cause you to trip. Hook on to the harness D-ring (marked A ) designed to arrest falls. 11

16 LANYARDS AND ANCHORS A lanyard is a flexible line of webbing or a synthetic or wire rope used to secure a safety belt or full body harness to a lifeline or anchor. Using the right lanyard A lanyard that meets the requirements of CSA Z259.1 is acceptable to the WSCC. Keep lanyards as short as possible to reduce the distance you could fall. Try to arrange the lanyard to limit a free fall to no more than 1.2 m (4 ft.) in a fall arrest situation. When using a wire rope lanyard for fall arrest, a personal shock absorber must be incorporated as part of your personal fall protection system in order to keep the arrest force at a safe level. Inspecting your lanyard Inspect the lanyard before each use. Check the rope or webbing, the snap hooks, and the manufacturer s label for additional user information. Rope or webbing Inspect along the length of the lanyard and the eye splices. If you have a three-strand rope lanyard, carefully twist the rope open to look for worn, broken, or cut fibres. Do not overtwist, or you could permanently deform the rope. Web lanyards should be discarded if the webbing has cuts or holes, is worn or frayed, or if the load-bearing stitches are damaged. If you find any signs of deterioration, burns, or broken or damaged strands, or if you have any reason to suspect the lanyard, do not use it. 12

17 Snap hooks CSA Standard Z259.1 requires snap hooks to be self-locking to prevent accidental roll-out. Roll-out can occur when small D-rings, or other attachment hardware, cause the snap-hook gate to push open in a twisting action thus separating the two components. Manufacturer s label The manufacturer s label on a CSAapproved lanyard will contain the following information: Manufacturer or vendor identification Length and diameter (if applicable) of the lanyard Material the lanyard is made of Date the lanyard was manufactured Model number Warning any unit which has seen fall arrest service should not be used after such service Personal shock absorbers A shock absorber slows and cushions the fall, reducing the force of stopping the fall. Personal shock absorbers are often made of tear webbing. In a fall, specific stitch patterns in the webbing absorb the force of impact and progressively tear apart. Warning: The shock absorber may increase the length of the lanyard by as much as 1.2 m (4 ft.) during a fall. Refer to the label on the shock-absorbing unit to determine the maximum elongation. Allow for this extra fall distance when you include a shock absorber in your personal fall protection system. Note: A personal shock absorber that meets CSA Standards Z is acceptable to the WSCC. 13

18 Carabiners A carabiner is an oblong-shaped connecting device used to attach different components of a personal fall protection system. A carabiner meeting the requirements of CSA Z is acceptable to the WSCC. A carabiner should: Have gates that are both self-closing and selflocking Have a breaking strength of at least 22 kn (5,000 lb.) Have the manufacturer s identity and load capacity clearly marked on it Inspect your carabiner before each use. Make sure it is free of damage, deformities, or excessive wear. Anchors An anchor what you connect your lanyard or lifeline to is a key element of any personal fall protection system. An anchor may consist of a load-rated strap or sling wrapped around a substantial structural member on a building. An anchor may also be a manufactured component that permanently or temporarily attaches to a structure. Selecting an anchor The selection of a suitable anchor depends on whether you want to restrain or arrest a fall. If you want to prevent or restrain yourself from falling, your anchor must be capable of supporting at least 3.5 kn (800 lb.) or, alternatively, the equivalent of four times the weight of the worker. If you want to arrest a fall, your anchor must be capable of supporting at least 22 kn (5,000 lb.). Alternatively, when the potential arrest forces are known, an anchor that is capable of supporting the equivalent of two times the maximum arrest force generated by a falling worker is acceptable. For example, the manufacturer will specify the maximum arrest force on personal energy-absorbing devices in the fall arrest system. Note: the anchor values above do not apply to horizontal lifeline systems, as the potential forces imposed on the anchors of a horizontal lifeline can be much greater than those for personal fall restraint and arrest systems. See pages 17 and 18 for information on acceptable horizontal life systems. 14

19 LIFELINES A lifeline is a length of synthetic fibre or steel wire rope attached to an independent point of anchorage. A lifeline is typically used in conjunction with a fall arrest device, such as a rope grab. Vertical Lifelines Using the right vertical lifeline The rope used as a vertical lifeline in a personal fall arrest system requires a minimum breaking strength of 26.7 kn (6,000 lb.). The reason for a breaking strength greater than that of the anchor is to allow for eye splices and knots tied in the rope at the anchor end. Splices and knots will weaken a rope; so, additional capacity of the lifeline is required. The following is good industry practice for the safe use of a vertical lifeline: No knots or splices in the lifeline except at the termination points Attach each lifeline to an independent point of anchorage Only one worker connected to a vertical lifeline The lifeline should extend to within 1.2 m (4 ft.) of the ground or safe lower landing, and If the suspended length of a lifeline exceeds 91 m (300 ft.), lanyard length, and the effects of wind, rope construction, and strength must be taken into account Inspecting a vertical line Exposure to sunlight causes most synthetic fibre ropes to deteriorate over time. Before each use, carefully inspect your lifeline to make sure it is in good condition. Look for signs of chafing or abrasion, cuts in the yarns or strands, or any visible deformities that would weaken the rope or interfere with the free movement of the rope grab. If you have any doubts about the condition of the lifeline, do not use it. 15

20 Rope Grabs A rope grab is a device that travels along a lifeline and will lock onto it in the event of a fall. Rope used with all rope grabs must be the diameter specified by the manufacturer. Ensure the rope grab is installed on the rope in the correct orientation so the top of the device is installed pointing toward the anchor. The two most common types of mechanical rope grabs are automatic and manual. An automatic (or mobile) rope grab moves freely along the lifeline with you. If you fall, it locks automatically and stops you after a short distance. If you are using an automatic rope grab, it is recommended that you limit your lanyard to 0.6 m (2 ft.) in length. An automatic rope grab meeting the requirements of CSA Standard Z is acceptable to the WSCC. A manual rope grab does not move freely with you. It is always in a locked position on the lifeline and must be re-positioned by hand. Manual rope grabs are best suited for use in fall restraint systems. The Canadian Standards Association (CSA) considers manual rope grabs to be rope adjusting implements. They are not covered by a CSA Standard, but are acceptable for use when operated in accordance with the manufacturer s instructions. 16

21 Swing-fall hazard Be careful not to tie off to an anchor in such a way that if you fall, you ll swing into an obstruction. This is called a swing-fall hazard. A swing fall can be as harmful as falling to the ground. Retractable lifelines A retractable lifeline is a specific type of vertical lifeline that works somewhat like the seat-belt of a car. The lifeline is coiled inside a protective housing. As you move up or down, the lifeline extends or retracts. The line is under constant tension and leaves no slack. The moment you fall, the lifeline locks and stops your fall after a short distance. Many retractable lifelines have fall indicators on their protective housings. Do not use the lifeline if the indicator shows that a fall has occurred. After a fall, the manufacturer or the manufacturer s authorized agent must inspect the lifeline and approve it for continued use. Always use a retractable lifeline block in the vertical position, unless specifically allowed for by the manufacturer. Horizontal lifelines A horizontal lifeline consists of a synthetic or wire rope, or fixed rail, rigged between two substantial anchor points. These lifeline systems allow the worker to move horizontally along the work surface while being connected to the lifeline. Horizontal lifelines and their anchors may be subject to extreme force in the event of a fall. Therefore, all permanently installed horizontal lifeline systems must be certified by a professional engineer. Temporary horizontal lifeline systems are acceptable if they are: 1. Manufactured for commercial distribution, and installed and used according to the written instructions provided 2. Installed and used according to the written instructions of a professional engineer, or 3. Installed and used according to each of the following requirements: 17

22 The horizontal lifeline is a minimum 12 mm (½ in.) diameter wire rope having a breaking strength specified by the manufacturer of at least 89 kn (20,000 lb.) The horizontal lifeline is free of splices except at the terminations Connecting hardware, such as shackles and turnbuckles, has an ultimate load capacity of at least 71 kn (16,000 lb.) The span is at least 6 m (20 ft.) and not more than 18 m (60 ft.) End anchors have an ultimate load capacity of at least 71 kn (16,000 lb.) The horizontal lifeline has an unloaded sag of approximately the span length divided by 60 The elevation of the line at any point is at least 1 m (39 in.) above the working surface The free fall distance is limited to 1.2 m (4 ft.) A minimum of 3.5 m (12 ft.) of unobstructed clearance is available below the working surface No more than three (3) workers are secured to the horizontal lifeline The horizontal lifeline is positioned so it does not impede the safe movement of workers AFTER A FALL After a fall, immediately remove from service all equipment used to arrest the fall. You cannot use the equipment again until it s been inspected and approved by the manufacturer or other approved agent, or by a professional engineer. 18
