Step 3: Evaluate risks and decide whether existing precautions are adequate or should more be done

Think before you start

Is it necessary to work in the heat? Can the job be redesigned? Can the environment, PPE and/or work rate be changed?

Planning and training

Planning and training may help employees understand thermal comfort and what their adaptive options may be should their comfort levels change.

Consult with employees

Ask them, their Union or other workplace representatives if they think more could and should be done. They are the experts at their jobs, and their views are essential in evaluating and mitigating the risks

Conduct a risk assessment

Conduct a risk assessment and interpret the results.

Draw up an action list

How can you reduce the risk of thermal discomfort? A possible order for problem solving may include:

Consider other options:
- wait for the thermal conditions to improve e.g. can any jobs be put off or rescheduled?;
- reduce metabolic rate by introducing lifting aids;
- change uniform to suit the working environment;
- provide heaters, coolers or air conditioning.
Prevent access to the hazard – eg only acclimatised workers.
Organise work to reduce exposure – eg work-rest schedules, job rotation, team rotation, more workers on job.
Issue appropriate PPE.
Provide welfare facilities – eg first aid and emergency procedures if they are deemed necessary.
