Hot Weather Guidelines

  • When temperatures reach over 90 degrees, the risk of heat-related illnesses can increase dramatically, particularly for those who are more sensitive to heat. Prolonged exposure to excessive temperatures may cause serious conditions like heat exhaustion or heat stroke and can even be fatal.

    Recommended precautions to prevent heat related illnesses:

    1. Drink plenty of water; don’t wait until you are thirsty.
    2. Avoid unnecessary sun exposure; wear a hat, preferably with a wide brim, when in the sun and use sunscreen.
    3. Avoid unnecessary exertion if you are outside or in non-air conditioned buildings. If you are working outdoors, take frequent rest and refreshment breaks in a shaded area.
