FLHA for mobile scaffold

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 mobile scaffold 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 falling from height, scaffold collapse or fall from scaffold, falling tools and materials and lifting and carrying heavy loads.

Job steps, hazards and controls

#	Job step	Hazards	Risk before	Controls	Risk after
1	Check all parts and the ground, and look up for power lines	Contact with overhead power lines Scaffold collapse or fall from scaffold	Critical	Ask the utility to de-energize, move or insulate the lines before work starts. Elimination Use non-conductive (fibreglass) ladders near any power lines. Substitution Mark the safe distance with flags, tape or goal posts and keep all equipment and people outside it. Engineering (guarding) Keep to the provincial limits of approach and contact the utility before working near lines. Administrative Use a dedicated spotter whenever equipment moves or raises anything near lines. Administrative Treat all lines as live. If equipment touches a line, stay in the cab and keep everyone well away. Administrative Scaffold is built, altered and taken down only by trained workers supervised by a competent worker, on a firm base with sole boards and ties. Engineering Fit guardrails, mid rails and toe boards on every working platform. Engineering Scaffold collapse or fall from scaffold: see step 4 for the full controls Administrative	Medium
2	Build to the instructions with outriggers and guardrails	Scaffold collapse or fall from scaffold Falling from height	Critical	Use mobile scaffolds only on firm, level ground with castors locked and outriggers fitted. Never move one with anyone on it. Engineering A competent worker inspects the scaffold before use each shift, after any change and after bad weather, and tags every access point: green safe, yellow caution, red do not use. Administrative Scaffold collapse or fall from scaffold: see step 4 for the full controls Administrative Do the work from the ground where you can, for example pre-assemble on the ground or use extension poles. Elimination Install guardrails or edge protection on all open edges before work starts. Engineering (guarding) Use a scaffold, mobile work platform or aerial work platform instead of working off a ladder. Engineering Where edge protection is not practical, use a fall restraint or fall arrest system on a rated anchor point. Engineering Fall protection plan in place where required. Workers trained in fall protection (Working at Heights training in Ontario). Administrative Have a rescue plan so a worker hanging in a harness can be brought down within minutes. Administrative Wear a full body harness with a shock-absorbing lanyard, clipped on at all times when using fall arrest. PPE	Medium
3	Lock the wheels before climbing, climb only on the inside	Scaffold collapse or fall from scaffold Falling from height	Critical	Do not overload platforms. Know the rated load and keep material stacks over the frames. Administrative Never remove ties, braces, guardrails or boards. Only the scaffolder alters the scaffold. Administrative Scaffold collapse or fall from scaffold: see step 4 for the full controls Administrative Falling from height: see step 2 for the full controls Administrative	Medium
4	Never move it with anyone or anything on it	Scaffold collapse or fall from scaffold Falling tools and materials	Critical	Scaffold is built, altered and taken down only by trained workers supervised by a competent worker, on a firm base with sole boards and ties.

Administrative Do not overload platforms. Know the rated load and keep material stacks over the frames. Administrative Never remove ties, braces, guardrails or boards. Only the scaffolder alters the scaffold. Administrative Wear a hard hat and safety boots on and around the scaffold. PPE Barricade and sign the drop zone under overhead work so nobody walks beneath. Engineering (guarding) Fit toe boards, kick plates and mesh screens on scaffolds and edges. Engineering Use catch fans, debris netting or covered walkways where people pass below. Engineering Tether hand tools when working at height. Engineering Keep platforms tidy. Do not stack materials near edges or above toe board height. Administrative Lower materials with a hoist, chute or rope. Never throw or drop anything down. Administrative Wear a hard hat anywhere objects could fall. PPE	Medium
5	Dismantle in reverse order and store parts	Lifting and carrying heavy loads	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	Medium

Hazards to watch on mobile scaffold

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

Step 1, 2, 3, 4Scaffold collapse or fall from scaffoldA scaffold that is badly built, overloaded or altered collapses or tips, or a worker falls from an unguarded platform.

Step 1Contact with overhead power linesA ladder, aerial work platform, crane, dump truck or long length of material touches or gets close to an overhead line and electrocutes people.

Step 2, 3Falling from heightA worker falls from an edge, platform or opening and is badly hurt or killed. Fall protection is needed from 3 metres, and at any height over machinery, water or other hazards.

Step 4Falling tools and materialsTools, materials or debris fall from above and hit someone working or walking below.

Step 5Lifting and carrying heavy loadsLifting, carrying, pushing or twisting with heavy or awkward loads strains the back, shoulders or knees.

Highest risk on mobile scaffold: 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):

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 an aerial work platform (scissor lift or boom lift)?
Was the building built before 1990?

Licences and legal requirements in Canada

Equipment on this job that needs a licence, ticket or training:

Rolling scaffold: Provincial scaffold training

Employers must identify hazards before work starts and control them, and workers must be told about them. A field level hazard assessment is done on site, at the start of each shift or task, and reviewed again when conditions change.

Rules that apply: Provincial OHS regulation, scaffolds; Provincial OHS regulation, fall protection.

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.
