FLHA for metal roof sheeting installation

Provincial OHS law requires hazards to be assessed and controlled before work starts. A field level hazard assessment (FLHA) for metal roof sheeting 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 falling from a roof edge, falling from height, scaffold collapse or fall from scaffold and being hit by heavy equipment.

Job steps, hazards and controls

#Job stepHazardsRisk beforeControlsRisk after
1Install scaffold edge protection and safety mesh before any sheets go up
  • Falling from a roof edge
  • Falling from height
  • Scaffold collapse or fall from scaffold
Critical
  • Do what you can from the ground or from a scaffold at the gutter line, for example pre-assemble parts on the ground. Elimination
  • Install edge protection or guardrails on all open roof edges before work starts. Engineering (guarding)
  • Use a perimeter scaffold with handrails and toe boards along the eaves where practical. Engineering
  • Where guardrails cannot be fitted, use fall restraint on certified roof anchors so workers cannot reach the edge. Engineering
  • Use one safe, controlled access point and keep others off the roof. 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
  • 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
  • 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

Medium
2Check wind speed and stop lifting or laying sheets in strong wind

  • 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)

Hazards to watch on metal roof sheeting installation

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

Step 6Burns from hot surfacesTouching hot pipes, tools, bitumen, solder or freshly welded metal burns the skin.
Step 3Crane and lifting failureA load falls or swings, or the crane tips, crushing workers under or near the lift.
Step 5Angle grinder injuriesThe disc shatters, binds or kicks back, causing deep cuts to legs and hands or eye injuries.
Step 1Scaffold 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 6Sun exposure (UV)Long hours in the sun cause sunburn, eye damage and skin cancer.
Step 3Contact 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.
Almost certainLikelyPossibleUnlikelyRareHow bad it could be: First aid only to FatalityBA
Highest risk on metal roof sheeting 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 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?
  • 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?
  • Was the building built before 1990, and will you sand, scrape, cut, heat or strip paint?

Licences and legal requirements in Canada

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

  • Frame scaffold: Provincial scaffold erector training
  • Telehandler: Provincial lift truck or telehandler operator training
  • Mobile crane: Provincial crane operator certification, qualified rigger

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, fall protection; Provincial OHS regulation, scaffolds; Provincial OHS regulation, cranes and hoisting.

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.

Questions

Do I need an FLHA for metal roof sheeting installation?

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

Who signs the FLHA?

The supervisor and every worker take part in the assessment and sign on before work starts, then sign off at the end of the shift. Review it and re-sign whenever the task or conditions change.

How long do I keep it?

Keep completed hazard assessments for at least 3 years (COR auditors sample the last 12 months). Review this FLHA and re-sign whenever the task, crew or conditions change.

What PPE is needed for metal roof sheeting installation?

Usually CSA green triangle safety boots (CSA Z195), Full body harness (fall arrest), Cut-resistant gloves, Safety glasses (CSA Z94.3), Hearing protection, Sun protection (sunscreen, hat, long sleeves), Hard hat (CSA Z94.1), High-visibility vest (CSA Z96), Work gloves, Face shield, Welding gloves, Coveralls, Safety goggles. The site rules may add more, so check with the general contractor.
