Toolbox: Field Level hazard Assessment (FLHA)

Spotting hazards isn’t always easy. Routine, repetition and familiarity can leave hazards ignored or overlooked. The purpose of this Procedure is to outline a process that encourages all workers to identify, assess and control hazards that have the potential to cause loss to people, property, materials or the environment – Field Level Hazard Assessment (FLHA)


FLHA is a systematic process conducted on a day- to- day, shift-to-shift basis, immediately prior to starting a job and when the job changes to identify and control hazards. For each job the following steps shall be followed:


  1. Identify main hazards of the job the purpose is to identify hazards to see how they relate to the job. Consider hazards that relate to the health and safety of workers, to equipment and to the environment.


  1. Assess the Hazards the assessment shall deal with the work that is to be completed that day, and focus on current conditions.


  1. Control Hazards list and describe the control measures that are put in place for the hazard.


  1. Begin or resume work when the hazards are adequately controlled


An FLHA form must be completed:

    • for all “hands on” work
    • immediately prior to starting a new job or new shift
    • when a new worker joins the crew
    • when the work changes, e.g. plans are modified, job scope changes, substitute equipment is provided, etc.
    • whenever work site conditions change that can affect the activity, e.g. weather, availability of tools, etc.
    • whenever the work task or equipment changes
    • whenever a change in another person’s activity on the work site could pose a hazard


Supervisors are responsible to conduct reviews, sign each FLHA and make recommendations for FLHA process improvements.
