    Managing Heat Stress - Part 2.

    In this episode host Mark Reggers and guest Dr Ross Di Corleto, Principal Consultant and Director of Monitor Consulting Services continue where they left off and resume their discussion on the subject matter of heat stress & strain in the workplace.

    Heat stress and heat strain are two different terms that are often incorrectly interchanged, using one phrase for the other. Heat stress refers to the net heat load to which a worker is exposed through physical exertion, environmental factors, and clothing worn. Heat strain is the body’s physiological response to heat stress, resulting in sweating, increased heart rate and elevated core temperature. Heat stress leads to heat strain which can give rise to heat-related illnesses or death if not managed correctly.

    In this episode, part 2 of 2, Mark & Ross discuss the following:

    • Using the hierarchy of control, what are the various measures that may be used when it comes to heat stress in the workplace.
    • Are all control measures appropriate?
    • When managing heat stress what do you need to look for?
    • How does the task itself impact on heat stress?
    • What are your thoughts on the work/rest regime control approach?
    • Are there any controls you believe are underutilised or could be better adopted?
    • When it comes to work/rest regimes, how important is the rest area environment?
    • Where does training sit in the overall control process?
    • We know that PPE is the last resort but what is available?
    • What clothing is appropriate for day to day work wear?
    • Is it possible to have a single temperature stop-work number?
    • Where can workplaces get more information on assessing and managing hot environments?

    There are many methods to manage heat stress, it is not just about the exposure and hydration. In the workplace, risks need to be assessed and prioritised, ensuring obligations are met and associated health and safety risks effectively managed. It’s important to understand that much of the impact of heat happens earlier than when we start to see the clinical symptoms of cramps and exhaustion. Once it reaches the heat illness stage we have left it too long, we need to catch it a lot earlier than that point. Working in hot and or humid environments can be uncomfortable, but more importantly, can lead to heat-related illnesses, which can be fatal. Tune in as we take an in-depth look at heat stress and the assessment and management of these working environments to ensure worker safety.
