TRADES GUIDELINES - ELECTRICAL It must be pointed out that every company or sub-contractor on the residential site is classified as an “employer” under the WSH Act – and have the same legal duties and responsibilities. In a nutshell, employers must ensure the safety and health of their workers and ensure that their actions (or lack of action) do not cause anyone else harm. By law, each employer must abide by the WSH Act, Regulations. Systems should be in place to: • Share required information necessary to Identify; Communicate and Control hazards • Ensure workers are supervised by a competent person (knowledge, training or experience) • Ensure workers are competent to perform the tasks assigned (instruction and training) • Ensure tools and equipment are maintained properly • Ensure PPE is provided and worn * Note: Adherence to the Electricians Licence Act may also be a requirement Further, each Employer is responsible to ensure plans are in place and their workers are aware of the following minimum emergency procedures: • Providing first aid to the injured • Providing transportation to medical aid for the injured • Conducting initial attack fire fighting; and • Promptly contacting outside agencies for assistance You should ensure Site Orientations are conducted and information is posted on site to cover the above, along with any other site specific hazards and controls – PPE Requirements; Communication Device; Emergency Phone Numbers; Muster Point; First Aid Kit; MSDS Sheets; Safe Work Practices. MAIN HAZARDS: The main hazards associated with Electrical Service Installation; Rough-in and Finish Work are: Electrocution; Slips and Trips; Falls; Knee and Back Injury; Cuts and Slivers; Struck by Objects (injuries to Eyes and Hands); and Chemicals. ELECTRICAL INSTALLATION & TEMPORARY POWER – SAFE WORK PRACTICES • Workers must be wearing the proper Personal Protective Equipment (PPE) such as a hardhat, safety footwear, hand protection, safety eyewear, hearing protection, and fall protection as required. • When digging a trench, refer and following the Safe Work Practices for Excavation & Trenching and ensure all utilities are located – contact “Call Before You Dig”. • Ensure the trench being used for service is adequately sloped (1:1 for previously excavated soil) and the spoil pile must be placed at least one meter away from the edge. • Wear hearing protection when drilling or cutting. • Refer to MSDS sheets for the safe handling requirements and appropriate personal protective equipment when caulking, solvent or glue. • Always remember to wash your hands after using caulking, solvents or glue before eating or smoking. • Clean up and pick up after yourself as you go; good housekeeping practices on the job site must be maintained. If bins are supplied – use them. If no bins, have piles designated for waste. • Check condition of temporary power box to ensure: panel cover is in place; GFCI receptacles; ground rod is secured and connected to the panel. • Clearly identify and protect temporary panels and cables from traffic, equipment, pinch points and other hazards. • Only use extension cords that have ground pins and are free of cracks, cuts or burn marks. • Do not modify or alter tools and do not use a tool for anything other than its intended purpose. • Ensure tools are in safe working order. Attach a “do not use” tag to damaged tools and notify your foreman. • If using a generator, place outside to keep exhaust from building up inside the house and to reduce noise levels. • Workers must receive WHMIS training and MSDS’s (Material Safety Data Sheet) must be on site. ELECTRICAL ROUGH-IN – SAFE WORK PRACTICE • Workers must be wearing the proper Personal Protective Equipment (PPE) such as a hardhat, safety footwear, safety eyewear, hearing protection, and fall protection as required. • Hang wire spools where they will not interfere with access to the work area and are easily rolled out. • Avoid awkward postures or pulling cable from above your head. Use work platforms or ladders to feed cable though joists. Stand on the floor when pulling cable. © 2007 Construction Safety Association of Manitoba July 2007 35 TRADES GUIDELINES - ELECTRICAL • • • • Keep hand tools in good condition. Sharp cutters make work quicker and are easier on the wrist. Ladders should be used for short-term work only. # 1 Rule: Never lean out while on a ladder – move the ladder Always open a step-ladder fully and lock the spreader arms. Clean up and pick up after yourself as you go; good housekeeping practices on the job site must be maintained. If bins are supplied – use them. If no bins, have piles designated for waste. • Prior to leaving a work site electrical panel covers must be in place. ELECTRICAL FINISHING WORK – SAFE WORK PRACTICE • Workers must be wearing the proper Personal Protective Equipment (PPE) such as a hardhat, safety footwear, safety eyewear, hearing protection, and fall protection as required. • Turn off power to all fixtures and switches. Ensure the circuits you are working on are properly Locked and Tagged out. • Prepare fixture on the ground to reduce time needed to work at heights and reduce overhead work or awkward postures. • Keep hand tools in good condition. Sharp cutters and wire strippers make work quicker and are easier on your hands and wrist. • Consider using small scaffolds or other appropriate work platforms instead of a ladder. • Ladders should be used for short-term work only. # 1 Rule: Never lean out while on a ladder – move the ladder • Always open a step-ladder fully and lock the spreader arms. • Clean up and pick up after yourself as you go; good housekeeping practices on the job site must be maintained. If bins are supplied – use them. If no bins, have piles designated for waste. • If finishing work is not completed at the end of a shift all panel covers must be re-installed and any exposed electrical work is locked and tagged out. GENERAL SAFETY INFORMATION 1. PPE (Personal Protective Equipment) PPE may be used as a method to help reduce identified hazards – as a “last line of defence”. Every effort to eliminate or reduce the hazard should follow this order: • At the Source (Elimination or Substitution) • Along the Path to the Worker (Modifications to Work or Process) • At the Worker (PPE) The WSH Act states that Safety Headwear and Safety Footwear must be made “readily available” for all personnel on a construction site (including new construction; renovations and any alterations or modifications to a structure, building or street) – and worn if a danger to an injury is present. Safety Headwear and Safety Footwear are mandatory PPE that must be “immediately available” or worn by any person on a construction site Required PPE to be worn or made “readily available” at residential construction sites include: Head Protection: Where a danger of injury to a worker’s head exists or may exist. overhead work is being done or where material is being hoisted overhead. Foot Protection: Where danger of injury to a worker’s foot exists or may exist. housekeeping is poor, material delivery, uneven terrain. E.g. where E.g. where Fall Protection: If working at heights over 10 feet, or less, if a worker may fall onto a hazard, fall protection is required. Generally your options will be guardrails; travel restraint or fall arrest systems. See special note on Residential Fall Protection above. Other PPE that may be required include: Eye Protection: Where danger of injury or irritation to a worker’s eye exists. E.g. during use of power or pneumatic tools (skill saws, quick-cut saws, sweeping, sawdust, etc.). 36 © 2007 Construction Safety Association of Manitoba July 2007 TRADES GUIDELINES - ELECTRICAL Respiratory Protective Equipment: When working with or around airborne contaminants that may be an inhalation hazard or if the airborne contaminant exceeds applicable Occupational Exposure Limits, respiratory protection is required. E.g. dusts or chemicals; mixing cement or stucco, sanding, etc. Hearing Protection: When noise levels in exceed 80 dBA, a hearing conservation program must be implemented. Ear muffs or Ear plugs should be worn when working with or around loud tools or equipment. E.g. skill saws, cutting, pneumatic tools. Limb and Body Protection: Where danger of injury to a worker’s hands, arms or legs, or trunk of the body exists suitable clothing and equipment must be worn – E.g. dust, material handling, kneeling, sun, etc. 2. Lifting Activities Caution and appropriate controls must be used during any lifting activity – to protect the load and the workers. Lifting on work sites is done either mechanically or manually. Whenever possible, lift and place heavy or awkward items using mechanical lifting devices. Mechanical Lifting: Equipment or machinery must be of sufficient size to safely lift anticipated loads. Equipment or machinery must be properly maintained. Workers must be competent in the operation of the equipment, including certification if cranes or forklifts are used. Manual Lifting: Proper lifting techniques should be employed (i.e. keep objects as close to the body as possible, lift with legs, not back). Know your limits, and ask a co-worker to help lift objects too heavy or awkward for one person, do not be afraid to ask for help. Eliminate potential tripping or slipping hazards before beginning to lift. 3. Access to the Work Area Proper access to the work area must be available at all times – this will normally be ladders, ramps or stairs during electrical activities. Ladders: Ladders should be used for short-term work only. Never lean out while on a ladder – move the ladder. Ladders used to access work areas should be grade 1. They must be secured from movement (normally tied off) and extend a minimum three feet above work level. The ladder should be positioned to maintain a 4:1 slope. Always maintain three-points of contact when climbing or descending a ladder. Ramps: Ramps should be constructed of at least two – 2 x 10 planks. They must be secured from movement and have a slope no greater than one vertical to three horizontal. Cross cleats must be provided at regular intervals to exceeding 1 ½ feet – and must be keep clear of snow, ice and mud accumulations. Stairs: Temporary stairs should be constructed to support any likely loads. They must be secured from movement; be uniform in width, length and height; with a slope not exceeding 50 degrees from horizontal. Open sides must have a handrail equivalent in strength to the top rail of a guardrail. 4. Trucking Operations and Mobile Equipment Trucking operations and mobile equipment are used to haul material or equipment to and from work sites. During homebuilding, the site can get very busy with backhoes, loaders, dump trucks, cement trucks and delivery vehicles. Protection of workers and/or the public is required in the working area. Traffic Control techniques should be implemented. Other general precautions should include: • Minimize the need for equipment backing up. If required, ensure vehicles and equipment have back-up alarms and workers wear high visibility vests. Ensure standard signalling procedures are known and followed by everyone involved (including drivers of delivery vehicles and spotter). • Be aware of the operators ‘blind spots’ – always maintain eye contact with the operator if you must approach equipment. • Never stand under a suspended load or raised forks, buckets or blades. • When receiving a load, use taglines to keep a safe distance between you and the load.

All equipment must be capable of performing the task for which it is to be used and must be properly maintained. 5. General Housekeeping is a major cause of residential incidents – scrap shingles and asphalt pebbles are often a cause of slips, trips and falls. It’s very important to keep your job site clean – clean up as you go. Use a bin or create dedicated scrap piles as soon as possible. From a safety standpoint, cables and cords should be kept clear of workspaces to prevent tripping hazards. It’s recommended for fire extinguishers to be readily available for trades working with open flames. There must be adequate lighting when performing work at all times. Prior to beginning work, a toolbox talk can be very beneficial. When safety discussions are held, the chances are higher that a safe job will result. To assist the general public in “awareness” of the potential and actual hazards – the first and simplest method is to Post a Sign and if the hazards warrant, you may need secure the site (i.e. fencing and warning tape) or the actual hazard (i.e. floor openings or access ramps / ladders).
