FLHA for site grading

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 site grading 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, road traffic and being hit by heavy equipment.

1Get utility locates, check for overhead power lines and plan truck movements
  • Hitting underground services
  • Contact with overhead power lines
  • Road traffic
Critical
  • Keep machine buckets well clear of marked services and use a spotter. Engineering (guarding)
  • Scan the area with a cable locator before digging and mark services on the ground. Engineering
  • Hand expose or hydrovac services before machine digging inside the locate tolerance zone. Engineering
  • Click Before You Dig: lodge a locate request with your provincial one-call service and wait for the locates. Administrative
  • Follow your province's ground disturbance rules and keep locate sheets on site. Administrative
  • Keep plans or locate tickets on site and check them again if the work area grows. Administrative

Pre-start checklist for site grading

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, check for overhead power lines and plan truck movements
  2. Set up a spotter and exclusion zones for machines
  3. Cut the site, battering or retaining cut faces
  4. Watch neighbouring fences and footings near the cut
  5. Control dust with water
  6. Load trucks and clean the street

Hazards to watch on site grading

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

Step 1, 6Road trafficPassing cars and trucks hit workers or plant working on or next to a road.
Step 3Trench 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 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 3, 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.
Step 2Being 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 site grading: Critical before controls (B), down to Medium after controls (A), on the Canada 5 by 5 risk matrix (likely and fatality becomes rare and fatality).

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
  • Skid steer: Provincial operator training
  • Dump truck: Provincial driver licence for the vehicle class

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.

Questions

Do I need an FLHA for site grading?

Provincial OHS law requires hazards to be assessed and controlled before work starts. A field level hazard assessment (FLHA) for site grading 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 site grading?

Usually CSA green triangle safety boots (CSA Z195), High-visibility vest (CSA Z96), Hard hat (CSA Z94.1), Hearing protection, N95 respirator, Safety glasses (CSA Z94.3), Respirator fit tested to CSA Z94.4 (P100 for dust, or the type the air test calls for), Work gloves. The site rules may add more, so check with the general contractor.
