Working during heatwaves can give rise to further health challenges and your union wants to make sure that you stay safe.

Most employers should have a high heat plan. Check with your manager or supervisor about your specific location’s heat plan to ensure that your health and safety is looked after. Your worksite Occupational Health & Safety (OH&S) Committee should also be examining the plan to be sure it is appropriate for the type of work done and the exposures you face.

You should take note of who the first aid attendants are in your office. Heat exhaustion and heat stroke can happen to anyone. If you are a first aid attendant, please be extra vigilant. Keep your eyes out for your co-workers who may be vulnerable to heat-related illnesses. Make sure everyone in your office knows who you are and that they can and must come to you if they are feeling unwell from the heat or if they notice a co-worker who is showing signs of distress.

Your OH&S Committee can also provide you with information on how handle the heat when working from home, but common ways to keep cool include closing shades to keep out the sun, dressing appropriately for the temperature, unplugging unneeded devices that generate heat, as well as opening windows in the evenings to cool down your home office when the temperatures are lower.

Staying properly hydrated is also critical. Your body is using more water than you realize, so drink lots of water throughout the day. Don’t just wait until you are feeling thirsty. As much as possible, stay out of the heat or seek shade. If your work requires you to be outside, be sure to wear protective clothing and equipment, such as pop-up shelters. You don’t need to be a hero. Please take care of yourself!

Signs and symptoms of heat cramp and heat exhaustion:

  • Move the person out of the heat and into a shady or air-conditioned place.
  • Lay the person down and elevate the legs and feet slightly.
  • Remove tight or heavy clothing.
  • Have the person drink cool water or other non-alcoholic beverage without caffeine.
  • Cool the person by spraying or sponging with cool water and fanning.
  • Monitor the person carefully.

Contact a doctor if signs or symptoms worsen or if they don’t improve within one hour.

Call 911 or your local emergency number if the person’s condition deteriorates, especially if they experience:

  • Hot, dry, flushed skin with absence of sweating
  • Agitation, confusion
  • Decreased level of consciousness
  • Nausea and vomiting
  • Seizures
