FLHA for wall framing

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

Provincial OHS law requires hazards to be assessed and controlled before work starts. A field level hazard assessment (FLHA) for wall framing 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, falling through a floor opening or void, saw cuts and kickback and wood and MDF dust.

Pre-start checklist for wall framing

Tick these off before work starts. They come from the hazards, permits and equipment in this job.

The safe sequence of work

  1. Set up a clean, level cutting area away from walkways
  2. Cut studs and plates with guards working, keeping hands clear of the blade
  3. Nail frames together on the deck, using sequential trigger on nail guns
  4. Stand frames with enough people and brace them straight away
  5. Guard slab or floor edges and openings near the work
  6. Clean up offcuts and nails at the end of each day

Hazards to watch on wall framing

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

Step 3Compressed airAn air hose whips when a fitting fails, or air blown at skin or eyes drives dirt in and causes injury.
Step 2Wood and MDF dustSawing and sanding timber, MDF and treated wood makes fine dust that causes asthma, skin problems and some cancers.
Step 3Nail gun injuriesA nail gun fires by accident, or a nail goes through the timber or ricochets and hits the user or someone nearby.
Step 4Strong wind and stormsWind blows sheets, panels and people off roofs and scaffolds, and storms and lightning make work at height and lifting unsafe.
Step 4Structural collapse during alterationsRemoving a wall, beam, post or bracing makes part of the building fall on workers.
Step 5Falling through a floor opening or voidA worker steps into an open hole, stairwell, lift shaft or penetration and falls to the level below.
Almost certainLikelyPossibleUnlikelyRareHow bad it could be: First aid only to FatalityBA
Highest risk on wall framing: 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.
