FLHA for bathroom demolition

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 bathroom demolition 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, disturbing asbestos, electric shock from live wiring and glass handling and breakage.

Job steps, hazards and controls

#	Job step	Hazards	Risk before	Controls	Risk after
1	Check wall and floor sheets for asbestos; older wet areas often have it	Disturbing asbestos	Critical	Get an asbestos survey before work on buildings built before 1990. Elimination Seal off the work area and keep everyone else out. Engineering (guarding) If asbestos must be disturbed, keep it wet, use hand tools not power tools, and clean up with a HEPA vacuum. Engineering Follow your province's asbestos rules, including notification and trained or certified workers where required. Administrative In BC, a qualified person must inspect and write a hazardous materials report before demolition or renovation, and asbestos abatement must be done by a WorkSafeBC licensed contractor (since 1 January 2024). Administrative Stop work straight away if you find suspect asbestos. Do not touch it and tell your supervisor. Administrative Wear a fit-tested respirator suited to the work, and disposable coveralls. PPE	Medium
2	Isolate water and power to the room	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	Remove fixtures and glass shower screens carefully	Glass handling and breakage Lifting and carrying heavy loads Sewage and wastewater	High	Use suction lifters, glass trolleys or a glazing robot for large panes. Engineering Store glass upright on racks and secure it. Never lay it flat or lean it loosely. Engineering Use two or more people for large panes, and clear the carry route first. Administrative Mark new glass with tape or stickers so nobody walks into it. Administrative Clean up broken glass straight away into a marked container. 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 Lifting and carrying heavy loads: see step 6 for the full controls Administrative Flush and drain the line before opening it, and plan the job to avoid contact. Elimination Use drain cameras, jetters and long-handled tools to keep hands out. Engineering Cover cuts with waterproof dressings. Never eat, drink or smoke before washing. Administrative Wash hands well and clean tools and boots after the job. Administrative Keep vaccinations such as tetanus and hepatitis A up to date, on medical advice. Administrative	Medium
4	Break off tiles and screed with dust control	Silica dust from concrete, brick, stone and tiles Loud noise Hand-arm and whole-body vibration Eye injuries	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 Use tool guards and screens to stop flying particles. Engineering Use dust extraction and water to keep dust out of the air. Engineering Keep others out of the area when cutting, grinding or chipping. Administrative Keep an eye wash station or eye wash bottles on site. Administrative	Medium
5	Check for mould and rot once linings are off	Mould and droppings	Medium	Fix the water leak and dry the area before removing mould. Elimination Seal off the area with plastic sheeting and keep occupants out. Engineering (guarding) Clean up with a HEPA vacuum and wet wipes. Never dry sweep. Engineering Bag mouldy material on site and remove it promptly. Administrative Wash hands and face before eating and at the end of each shift. Administrative Wear an N95 (or better) respirator, gloves, goggles and disposable coveralls. PPE	Low
6	Bag and remove waste, then vacuum	Lifting and carrying heavy loads Poor housekeeping and waste	High	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 Rotate tasks and take breaks on long lifting jobs. Administrative Wear gloves for grip and safety boots to protect your feet. PPE 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 bathroom demolition

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

Step 5Mould and droppingsWater-damaged buildings, bird and rat droppings and dead animals hold mould and germs that cause breathing problems and infections.

Step 3Sewage and wastewaterContact with sewage spreads germs that cause stomach illness, hepatitis and skin infections.

Step 3Glass handling and breakageGlass panes break while being moved or fitted, causing deep cuts, or heavy panels fall and crush.

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

Step 4Hand-arm and whole-body vibrationLong periods on jackhammers, grinders, compactors or riding plant cause white finger, numbness and back damage.

Step 1Disturbing asbestosBuildings built before 1990 may contain asbestos. Drilling, cutting or breaking it releases fibres that cause cancer years later.

Highest risk on bathroom demolition: Critical before controls (B), down to Medium after controls (A), on the Canada 5 by 5 risk matrix (likely and fatality becomes unlikely and serious 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.
