FLHA for brick fence construction

By SiteSortedBuilt 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 brick fence construction 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 silica dust from concrete, brick, stone and tiles, hitting underground services, trench or excavation collapse and being hit by heavy equipment.

Hazards to watch on brick fence construction

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

Step 2Trench or excavation collapseThe trench walls cave in and bury or crush a worker. Trenches deeper than 1.2 metres (1.5 metres in Alberta and Manitoba) need support or sloping.
Step 5Sun exposure (UV)Long hours in the sun cause sunburn, eye damage and skin cancer.
Step 2Wet concrete and cement burnsWet concrete, mortar and cement burn skin and eyes. Burns can be deep and are often not felt until later.
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 1Hitting underground servicesDigging, drilling or driving pegs hits a buried power cable, gas pipe or water main, causing electrocution, explosion or flooding.
Almost certainLikelyPossibleUnlikelyRareHow bad it could be: First aid only to FatalityBA
Highest risk on brick fence construction: Critical before controls (B), down to Medium after controls (A), on the Canada 5 by 5 risk matrix (likely and fatality becomes unlikely and lost time 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, excavations and trenches; Provincial OHS regulation, silica exposure limits.

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.
