PPE can make a hot task more demanding. The response should be a planned review of the work and equipment, rather than removing protection while exposure continues.
Raise discomfort early
Tell the supervisor if heat is making the task difficult. Review the work rate, duration and cooling arrangements before the situation worsens. HSE’s heat-stress guidance explains why air temperature alone does not describe the risk.
Use task-appropriate equipment
Ask whether an alternative approved model offers a better fit or useful comfort features. Ventilation is only suitable when it is compatible with the hazard. A fabric face covering is not a substitute for respiratory protection specified for a workplace exposure.
Make breaks part of the plan
Provide suitable breaks in a safe, cooler area and access to drinking water. Follow the workplace procedure for leaving the exposure area and removing equipment. Do not alter a respirator, cut clothing or make unofficial changes to PPE to cool down.
Check the full combination
Try the equipment together: glasses, respirator, helmet and clothing can affect one another. Record the models that work for each wearer and use the manufacturer’s care and replacement instructions.
