FLHA for EV charger installation

By Safety PaperworkBuilt from provincial OHS law and CCOHS guidance · How we write and check theseUpdated November 9, 2026

Provincial OHS law requires hazards to be assessed and controlled before work starts. A field level hazard assessment (FLHA) for EV charger installation is done on site at the start of the shift and again whenever conditions change.

It lists the tasks, hazards and controls, and every worker signs on before starting and signs off at the end of the shift. The main hazards are silica dust from concrete, brick, stone and tiles, hitting underground services, electric shock from live wiring and road traffic.

Job steps, hazards and controls

#	Job step	Hazards	Risk before	Controls	Risk after
1	Check the supply capacity and plan the cable route away from gas and water lines	Gas and fuel lines Hitting underground services	Critical	Isolate and purge the line before work, with the owner's approval. Elimination Lock off and tag the isolation valve. Engineering (guarding) Check for leaks with a gas detector before and during work, and ventilate the area. Engineering Only licensed gas fitters work on gas lines. Administrative Remove ignition sources: no smoking, no hot work and no sparking tools near the line. Administrative Know where the shut-off valve is and what to do if a leak happens. Administrative Wear safety glasses and gloves, and keep a fire extinguisher close by. PPE Keep machine buckets well clear of marked services and use a spotter. Engineering (guarding) Scan the area with a cable locator before digging and mark services on the ground. Engineering Hand expose or hydrovac services before machine digging inside the locate tolerance zone. Engineering Click Before You Dig: lodge a locate request with your provincial one-call service and wait for the locates. Administrative Follow your province's ground disturbance rules and keep locate sheets on site. Administrative Keep plans or locate tickets on site and check them again if the work area grows. Administrative If you hit a service, stop, get everyone clear, and call the owner and emergency services. Administrative Wear safety boots, gloves and hi-vis when digging. PPE	Medium
2	Isolate at the electrical panel, apply lockout and tags and test to prove dead	Electric shock from live wiring Stored energy	Critical	Isolate the power before any work. Do not work live. Elimination Lock out and tag the isolation point with your own personal lock and danger tag. Engineering (guarding) Test before you touch: prove dead at the point of work with a tested voltage tester. Engineering Only licensed electricians do electrical work, to the Canadian Electrical Code and provincial rules. Administrative Check for back feeds from solar, batteries and generators that can keep a circuit live after the main switch is off. Administrative If energized work cannot be avoided, use a permit, a safety observer and insulated tools, following CSA Z462. Administrative Wear insulated gloves, arc-rated clothing and a face shield when testing or working near live parts. PPE Release or block all stored energy before work: release the pressure in pipes, tanks and hoses, bleed hydraulics, release springs, lower loads. Elimination Lock out and tag all energy sources with personal locks. Engineering (guarding) Put mechanical blocks or props under raised parts like buckets, tipper bodies and doors. Engineering Test that the system is dead and nothing can move before you start. Administrative Follow the maker's procedure, for example for garage door and roller door springs. Administrative Wear safety glasses and gloves. PPE	Medium
3	Drill through brick or concrete with dust extraction	Silica dust from concrete, brick, stone and tiles Loud noise Hand-arm and whole-body vibration Injury from power tools	Critical	Order materials cut to size, or use low-dust methods such as score and snap or a block splitter. Substitution Cut outdoors or in a separate area, with other people well away and upwind. Engineering (guarding) Use water on the blade or on-tool dust extraction connected to a HEPA vacuum. Engineering Clean up with a vacuum or wet methods. Never dry sweep or use compressed air. Administrative Have a silica exposure control plan where your province requires one. Administrative Use quieter tools and methods, such as cut-to-size materials, low-noise machines and battery tools. Substitution Keep noisy equipment away from work areas, and use screens or distance between the noise and people. Engineering (guarding) Keep tools maintained and use mufflers on compressors and generators. Engineering Limit time on noisy tools and rotate workers. Administrative Use low-vibration tools and methods, such as a breaker on an excavator instead of a hand jackhammer. Substitution Keep tools sharp and well maintained, and use anti-vibration handles and seats. Engineering Limit trigger time on high-vibration tools and rotate workers. Administrative Keep hands warm and dry, and take regular breaks. Administrative Keep all guards fitted and working. Never tie back or remove a guard. Engineering Clamp or secure the work piece. Do not hold it by hand. Engineering Only trained, competent people use power tools, following the maker's instructions. Administrative Check tools before use. Unplug or remove the battery before changing blades or bits. Administrative	Medium
4	Run the cable and mount the charger, keeping cables out of walkways	Slips and trips Lifting and carrying heavy loads Road traffic	Critical	Plan walkways and keep them clear of materials, hoses and leads. Elimination Run leads and hoses overhead on hooks or stands, or along walls, not across walkways. Engineering Fill or cover holes, and lay boards or mats on muddy access paths. Engineering Clean up offcuts, packaging and spills as you go, not at the end of the day. Administrative Keep work areas, stairs and access paths well lit. Administrative Plan to avoid carrying: have materials delivered, and old items picked up, as close as possible to where they are used. Elimination Use lighter or smaller loads: order smaller bags and shorter lengths, and drain or break down old items before moving them. Substitution Use trolleys, pallet jacks, hoists, vacuum lifters or equipment instead of carrying by hand. Engineering Use a two-person lift for anything heavy, long or awkward. Plan the route first and clear it. Administrative Keep the load close, back straight and no twisting. Turn with your feet. Administrative Do the work at low-traffic times, or close the road or lane with approval. Elimination Put solid barriers between the work and traffic where speeds are high, not just cones. Engineering (guarding) Use a truck-mounted attenuator or buffer vehicle on high speed roads. Engineering Set up signs and cones to your provincial traffic control manual, with trained traffic control persons. Administrative Get a road occupancy permit from the municipality or road authority before you start. Administrative	Medium
5	Terminate at the electrical panel and charger, fitting the right GFCI protection	Electric shock from live wiring Electric shock from cords and power tools	Critical	Electric shock from live wiring: see step 2 for the full controls Administrative Use battery-powered tools where you can. Substitution Use GFCI protection on all temporary power and portable tools. Engineering Keep cords off the ground and out of water, using stands or hooks. Engineering Check cords, plugs and tools before every use. Tag out and remove anything damaged. Administrative Do not use tools in rain or wet areas unless they are rated for it. Administrative Wear safety boots and dry gloves. PPE	Medium
6	Test, commission the charger with the client and clean up	Electric shock from live wiring Poor housekeeping and waste	Critical	Electric shock from live wiring: see step 2 for the full controls Administrative Order materials to size and send packaging back where you can. Elimination Put waste bins and chutes close to the work. Engineering Clean as you go, and do a full clean up at the end of each day. Administrative Keep exits, stairs and walkways clear at all times. Administrative Stack materials neatly on level ground, away from edges. Administrative Wear gloves when handling waste. PPE	Medium

Hazards to watch on EV charger installation

The hazards most specific to this job, and the step where each one comes up.

Step 4Road trafficPassing cars and trucks hit workers or plant working on or next to a road.

Step 5Electric shock from cords and power toolsDamaged cords, plugs or tools, or water near power, give the user an electric shock.

Step 2Stored energyEnergy left in springs, hydraulics, compressed gas, raised loads or capacitors releases suddenly and crushes or injures workers.

Step 1Gas and fuel linesDamaging or opening a gas or fuel line causes a leak, fire or explosion.

Step 3Hand-arm and whole-body vibrationLong periods on jackhammers, grinders, compactors or riding plant cause white finger, numbness and back damage.

Step 1Hitting underground servicesDigging, drilling or driving pegs hits a buried power cable, gas pipe or water main, causing electrocution, explosion or flooding.

Highest risk on EV charger installation: Critical before controls (B), down to Medium after controls (A), on the Canada 5 by 5 risk matrix (likely and fatality becomes unlikely and lost time injury).

What changes on your site

This example covers the job itself. Your site may add more. Add controls for any of these that apply (the builder asks you these as yes or no questions):

Could anyone fall 3 metres or more, or fall any distance into machinery, water, a hazardous substance or through an opening?
Will anyone use a ladder or stepladder?
Will anyone work on a roof?
Is there a fragile roof, skylight or clear roof sheet?
Will you use a scaffold or mobile tower?

Why FLHAs get rejected

Prime contractors and COR auditors send documents back for these reasons. This example avoids them, but check yours too.

End of shift boxes already say "None" when the form was signed at the start of the shift.
One FLHA reused for days or weeks, or a "review by" date a month away, when the work and conditions change daily.
No time of assessment and no record of any revision, which Alberta s.7(3) requires.
Workers signed that they "read" it, but nothing shows they took part, which Alberta s.8(1) requires.
Work at height with no fall protection plan where the province requires one, or no written rescue procedure for workers using fall arrest.
Permits or locates required on site but no permit or ticket numbers recorded.
No re-assessment entry after an obvious change such as weather, a new task or a new crew member.
