FLHA for fence installation

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 fence 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 hitting underground services, disturbing asbestos, falling through a floor opening or void and being hit by heavy equipment.

Pre-start checklist for fence installation

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

The safe sequence of work

  1. Get utility locates and agree the boundary with neighbours
  2. Check old fencing for asbestos before removal
  3. Dig post holes and cover open holes
  4. Set posts in concrete
  5. Fix rails and sheets, watching sharp edges
  6. Clean up

Hazards to watch on fence installation

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

Step 6Sun exposure (UV)Long hours in the sun cause sunburn, eye damage and skin cancer.
Step 4Wet concrete and cement burnsWet concrete, mortar and cement burn skin and eyes. Burns can be deep and are often not felt until later.
Step 1Hitting underground servicesDigging, drilling or driving pegs hits a buried power cable, gas pipe or water main, causing electrocution, explosion or flooding.
Step 3Falling through a floor opening or voidA worker steps into an open hole, stairwell, lift shaft or penetration and falls to the level below.
Step 2Disturbing asbestosBuildings built before 1990 may contain asbestos. Drilling, cutting or breaking it releases fibres that cause cancer years later.
Step 3Being hit by heavy equipmentExcavators, loaders, telehandlers and trucks run over or crush workers, especially when reversing or slewing.
Almost certainLikelyPossibleUnlikelyRareHow bad it could be: First aid only to FatalityBA
Highest risk on fence installation: Critical before controls (B), down to Medium after controls (A), on the Canada 5 by 5 risk matrix (possible 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?

Licences and legal requirements in Canada

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

  • Excavator: Provincial operator 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, asbestos; 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.
