Some contractors skip the risk assessment entirely because they don't understand the need.

Others complete it as a formality, a box to check before the real work starts. The form gets filled out and signed, but no one walks the scope, challenges the hazards, or confirms the controls exist. Either way, the result is the same.

When management sees the risk assessment as administrative burden instead of a planning tool, hazards slip through to the work front. Workers get hurt. Projects get delayed. Costs spike.

The need starts with the law. Alberta's OHS Code (Part 2, Section 7) requires employers to assess a work site and identify existing and potential hazards before work begins. Saskatchewan's OHS Regulations (Section 3-11) and Manitoba's Workplace Safety and Health Act (Section 7.4(5)) also require employers to identify existing and potential hazards and the measures to control them, often under the name hazard assessment. The risk assessment is where a project decides which hazards it will control, and how, before anyone is exposed. Skipping it breaks the law and leaves injuries, damaged equipment, and lost schedule to chance.

Understanding what risk assessments and JHAs accomplish starts with separating the three levels where they happen.

Three Levels, One System

The project-level risk assessment is completed by management and Safety before mobilization. It covers the full scope of work, identifies high-risk activities, and sets the controls, procedures, and resources crews will work under. It also determines which tasks require a Job Hazard Analysis. Safety records the identified risks, controls, and owners in the project risk register and keeps it current for the duration of the job. The findings feed directly into the Site Safety Execution Plan and its supporting plans, such as the Emergency Response Plan, Confined Space Entry Plan, and Fall Protection Plan.

The Job Hazard Analysis (JHA) is developed for each task the project assessment flags. It breaks the task into steps and sets out the hazards and controls for each one, before the work is scheduled. Supervisors develop it with input from the crews doing the work, and Safety reviews it.

The Field Level Risk Assessment (FLRA) is completed by the crew at the work front before a task starts, and again when conditions change. Where a JHA applies, the crew reviews it as part of the FLRA and confirms its controls still fit the conditions that day. The supervisor reviews the FLRA and signs off before work proceeds.

Each level covers what the others can't. The project assessment sets the plan. A JHA turns that plan into step-by-step controls for the highest-risk tasks, and the FLRA checks both against the conditions crews face each day. When the project level is skipped, no one decides which tasks need a JHA, and crews are left solving planning problems at the work front.

Consider a confined space entry that no one flagged before mobilization. There's no Confined Space Entry Plan, the Emergency Response Plan doesn't cover a rescue from that space, and no rescue equipment or trained standby team is on site. The crew can complete a thorough FLRA on the day and still have no way to get a worker out if the atmosphere changes. An FLRA confirms that controls exist at the work front. It can't produce a rescue plan, procure equipment, or train a rescue team once the crew is standing at the entry point.

The Canadian Armed Forces has a saying: the first casualty on any battlefield is the plan. Conditions change once work starts, which is why the FLRA exists. When there's no plan at all, crews have nothing to adjust and have to work out every hazard from scratch at the work front. The CAF addresses this through battle procedure, a structured sequence that takes leaders from assessing the task to confirming their people understand the plan before anyone moves. The project-level assessment, JHAs, and FLRAs follow the same discipline.

FLRAs Catch What Crews Would Otherwise Miss

The human brain filters information constantly. It focuses on what matches the current task and ignores everything else. That's how attention works under pressure, and it affects experienced workers as much as new ones.

The cost shows up in Western Canadian data. From 2021 to 2025, WorkSafeBC accepted about 38,000 construction claims, including more than 7,400 serious injuries, 174 of them fatal. Over the past decade, B.C. construction cut its serious injury rate by 32%, an improvement WorkSafeBC links to more effective hazard identification that actively involves workers.

Research puts a number on it. Through 4,800 hours of worker observation, Dr. Matthew Hallowell found that workers identified only about 45% of hazards in the field without systematic tools. Experience doesn't fix this. Even seasoned crews miss what their brains aren't primed to see.

The FLRA forces the pause at the work front. It gives the crew a structure to catch gravity hazards, energy sources, and environmental factors in the conditions they face that day, before anyone gets exposed.

OSHA confirms that failure to identify or recognize present hazards ranks as a root cause of workplace injuries and incidents.

FLRAs Turn Supervisors Into Leaders

Frontline supervisors hold the entire safety program together. They directly oversee the crew, and the FLRA is where that responsibility shows up every shift.

The crew completes the FLRA. The supervisor reviews it, challenges weak or missing hazard identification, confirms the controls are actually in place, and signs off. That review is where a supervisor demonstrates competence, shows the crew what matters, and intervenes before conditions deteriorate.

Research confirms this. Frontline supervisors play a significant role in mediating workers' behavior, making their accountability vital for elevating site safety. They're the central link between management, safety personnel, and field workers, and the point where programs either hold or break.

A reviewed and signed FLRA gives the supervisor a framework to lead through hazard recognition. It sets out what needs control, who owns each control, and the standard that applies before work begins. That's leadership under load, with safety built into how the crew is run.

Every Level Protects Workers, Equipment, and Profitability

Every incident that doesn't happen means a worker goes home uninjured, equipment stays in service, and the project's schedule, budget, and reputation stay intact.

Canadian research shows the financial side too. An Institute for Work & Health study of Ontario employers found that construction companies with strong safety performance earned an average 34% return on their health and safety investment.

Used properly, risk assessments and JHAs protect workers from injury, equipment from damage, and production from the disruptions that stall schedules. When a crew stops work because someone got hurt, companies lose more than that worker's time. The whole crew loses momentum, and the company takes on investigations, regulatory scrutiny, and insurance claims.

The time invested at each level, whether a project-level risk assessment before mobilization, a JHA for a high-risk task, or an FLRA at the work front, prevents far more costly consequences: injured workers, damaged equipment and property, incident investigations, legal exposure, and schedule delays.

Documented Controls Create Accountability Before Problems Emerge

The project-level risk assessment documents what an organization knew before work started and what controls it put in place. That record matters when regulators show up, when lawyers ask questions, and when crews need to understand why certain controls exist.

JHAs record how each high-risk task will be done, step by step, and which controls apply at each stage. Signed FLRAs add the daily record. They show what each crew identified at the work front, which controls were confirmed, and which supervisor signed off.

The bigger value is operational clarity. When all three levels are done properly, everyone knows what hazards exist, what controls apply, and who owns each piece. Expectations are clear, and there's little room to argue later that a hazard wasn't foreseeable. Work moves forward with hazards identified and controls in place, and that accountability is set before work starts, when it can still prevent harm.

The System Supports Proactive Safety Management

Risk assessments, audits, and inspections have been standard practice for decades. Some organizations still complete them as a formality instead of using them to plan and control the work.

Proactive safety management means reducing risk to as low as reasonably practicable (ALARP), eliminating or controlling hazards until any further reduction would take time, cost, or effort grossly out of proportion to the benefit. Used properly, these tools move organizations from responding to incidents toward controlling hazards before work starts. The focus shifts from what went wrong to what could go wrong, and leaders get the information they need to intervene early.

When crews complete FLRAs consistently and supervisors review them properly, the records show which hazards keep showing up and which controls aren't holding. Safety feeds that information back into the risk register and updates the affected JHAs, so management can adjust procedures, equipment, or planning before the next crew faces the same hazard. Over time, all three levels build knowledge that protects future crews.

Three Levels, Done Right

The system works when all three levels are done properly. Management and Safety complete the project-level assessment before mobilization, so crews start the job with major hazards planned for, controls in place, and high-risk tasks flagged for a JHA.

For those tasks, the JHA sets out each step and its controls before the work is scheduled. At the work front, crews review the JHA where one applies and complete an FLRA before each task and again when conditions change. That catches what planning couldn't see, along with the hazards the brain would otherwise filter out.

Supervisors hold the levels together. They develop the JHAs, review and sign off the FLRAs, and confirm the controls are real. What crews find goes into the risk register and the JHAs for the people planning the work.

Contractors who skip the project-level assessment leave all of that work to the crew at the work front, with less time, less information, and more pressure.

The hazards are there either way. Organizations decide whether they get found in planning, in the JHA, at the work front during the FLRA, or in an incident investigation afterward.

On your current project, how many of the hazards crews flag in their FLRAs should have been caught in the project-level assessment or a JHA?

A thorough FLRA can't rescue a worker from a confined space that no one planned for.

If that entry wasn't flagged before mobilization, there's no Confined Space Entry Plan, no rescue equipment on site, and no trained standby team. The crew can do everything right at the work front that day and still have no way to get someone out if the atmosphere changes.

That's the risk when the project-level assessment is skipped or treated as a formality. Planning problems get handed to the crew, who have less time, less information, and more pressure than anyone in the planning meeting had.

Each level has its own job. The project-level risk assessment sets the plan and flags high-risk tasks for a Job Hazard Analysis, which breaks each task into steps with controls. The FLRA then checks both against the conditions crews face that day.

I wrote a longer piece on why each level matters. It covers the legal requirements in Alberta, Saskatchewan, and Manitoba and the supervisor's role in reviewing FLRAs. Link in the comments.
