FLHA for door installation

By SiteSortedBuilt 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 door 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 lead paint dust and fumes, lifting and carrying heavy loads, saw cuts and kickback and wood and MDF dust.

Job steps, hazards and controls

#	Job step	Hazards	Risk before	Controls	Risk after
1	Set up a work area away from occupants and walkways	Working in an occupied home or building Slips and trips	Medium	Plan noisy, dusty or risky work for when the building is empty. Elimination Close off the work area with barriers, plastic sheeting or locked doors, and put up signs. Engineering (guarding) Keep fire exits and paths clear at all times. Administrative Tell occupants before you turn off power, water or gas, and before noisy or dusty work. Administrative Lock away tools, chemicals and materials each day, out of reach of children. Administrative Clean up dust and debris at the end of each day. Administrative 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 Wear safety boots with good grip, laced up. PPE	Low
2	Remove old doors and frames, checking old paint for lead	Lead paint dust and fumes Lifting and carrying heavy loads	High	Test old paint for lead before you sand, scrape, cut or heat it. Elimination Use wet scraping, chemical strippers or shrouded tools with extraction instead of dry sanding. Never burn off lead paint with an open flame. Substitution Seal off the work area with plastic sheeting and keep residents, children and pets out. Engineering (guarding) Clean up with a HEPA vacuum and wet wipes. Never dry sweep. Engineering Wash hands and face before eating, drinking or smoking. Change out of dusty clothes before going home. Administrative Wear a fit-tested respirator with P100 filters, disposable coveralls and gloves. PPE 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 4 for the full controls Administrative	Medium
3	Trim doors to size and rout hinges with dust extraction	Saw cuts and kickback Wood and MDF dust Injury from power tools Loud noise	High	Keep blade guards fitted and working, and use the riving knife on table saws. Engineering Use push sticks and clamps, and support long pieces so they do not pinch the blade. Engineering Use a sharp, undamaged blade made for the material. Administrative Stand to one side of the blade line, out of the kickback path. Administrative Buy pre-cut or pre-finished timber where you can. Substitution Cut outdoors or in a well-ventilated area away from others. Engineering (guarding) Use saws and sanders with dust collection connected to a HEPA vacuum. Engineering Clean up with a vacuum, not a broom or compressed air. 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 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	Medium
4	Hang the door with help, as solid and fire doors are heavy	Lifting and carrying heavy loads Repetitive work and awkward postures	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 Use tools that cut the effort: powered screwdrivers, long-handled tools and extension poles for overhead work. Substitution Set work up at waist height on benches or trestles where you can. Engineering Use light tools with good grips, and keep blades and bits sharp. Engineering Rotate tasks and take short breaks every hour on repetitive work. Administrative Warm up before heavy physical work and report aches and pains early. Administrative Wear knee pads for kneeling work and gloves for grip. PPE	Medium
5	Fit locks and closers, test operation and clean up	Injury from power tools Poor housekeeping and waste	Medium	No loose clothing, jewellery or long hair near spinning parts. Administrative Wear safety glasses and hearing protection. Do not wear loose gloves on drills or other rotating tools. PPE Injury from power tools: see step 3 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 door installation

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

Step 3Wood and MDF dustSawing and sanding timber, MDF and treated wood makes fine dust that causes asthma, skin problems and some cancers.

Step 2Lead paint dust and fumesPaint from before 1960 almost always contains lead, and paint up to 1990 may. Sanding, scraping or heating it releases dust or fumes that poison workers and families, especially children.

Step 1Working in an occupied home or buildingResidents, staff or children wander into the work area and get hurt, or the work blocks exits or cuts off power or water while people are inside.

Step 3Saw cuts and kickbackCircular saws, mitre saws and table saws cut fingers and hands or throw material back at the user.

Step 3, 5Injury from power toolsDrills, saws, routers and sanders kick back, catch clothing or throw debris, causing cuts, broken bones and eye injuries.

Step 4Repetitive work and awkward posturesDoing the same movement for hours, kneeling or working overhead causes long-term damage to joints, muscles and tendons.

Highest risk on door installation: High before controls (B), down to Medium after controls (A), on the Canada 5 by 5 risk matrix (possible and serious injury 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.
