Extreme heat

The Houston area has very hot summers, and sometimes spring and fall temperatures also reach dangerous levels.  Knowing heat safety and how to recognize heat-related illnesses can help save you or someone else.

An Excessive Heat Warning is issued within 12 hours of the onset of extremely dangerous heat conditions. The general rule of thumb for this Warning is when the maximum heat index temperature is expected to be 105° or higher for at least two days and night time air temperatures will not drop below 75°; however, these criteria vary across the country, especially for areas not used to extreme heat conditions. If you don't take precautions immediately when conditions are extreme, you may become seriously ill.

A Heat Advisory is issued within 12 hours of the onset of extremely dangerous heat conditions. The general rule of thumb for this Advisory is when the maximum heat index temperature is expected to be 100° or higher for at least 2 days, and nighttime air temperatures will not drop below 75°; however, these criteria vary across the country, especially for areas that are not used to dangerous heat conditions. Take precautions to avoid heat illness. If you don't take precautions, you may become seriously ill.

How to Prepare

Recognizing Heat-Related Illnesses

During extremely hot and humid weather, your body's ability to cool itself is challenged. If the body cannot cool itself properly or dehydration occurs, body temperature can rise further, which may cause a heat-related illness.

Heat Exhaustion

Heat exhaustion is characterized by heavy sweating, weakness, dizziness, nausea, and headaches. If you experience these symptoms, immediately move to a cooler area, hydrate, and rest. Avoiding strenuous activities is crucial until symptoms subside.

Heat Stroke

Heat stroke is a severe condition that demands immediate medical attention. Symptoms include a body temperature spike, confusion, loss of consciousness, and rapid pulse. If you suspect heat stroke, call 911 without delay.

Staying Hydrated

Proper hydration is important in high temperatures:

  • Drink water regularly, even if you're not thirsty.
  • Minimize caffeine, alcohol, and sugary beverage consumption, as they contribute to dehydration.
  • Monitor your urine, you should go regularly and the color should be pale yellow.
Dress for Success

Wearing heat-appropriate attire helps regulate your body temperature:

  • Opt for lightweight, loose-fitting clothing.
  • Choose light colors to reflect sunlight.
  • Consider natural fibers like linen for their breathability but be aware of sun exposure, as you can get sunburns through clothing!

Athletic Heat Safety

For our athletes, safety comes first:

  • Coaches closely monitor weather conditions and may adjust practice schedules to avoid extreme heat.
  • Athletes should hydrate before, during, and after activities.
  • Frequent breaks are integrated to prevent overheating.
Heat Safety at Campus Events

Events should be enjoyable and safe for everyone:

  • Outdoor events feature shaded areas and water stations.
  • Attendees are encouraged to wear protective gear, including hats and sunglasses.
  • Event organizers track weather forecasts and change plans when needed.

Fire weather safety

In drought-like conditions, fires can be ignited easily and spread quickly: be fire smart!

  • Limit the use of open flames including fire pits, grilles, torches, and candles.
    Note: The City of Houston Fire Code prohibits open flame in and around the Colleges. No smoke or vapor producing devices is allowed in and around colleges. Candles, incense, flammables and flammable liquids, and any type of incendiaries are prohibited.
  • Smoking is always limited to designated smoking areas, consider curtailing your use of cigarettes during Red Flag warnings as wind can carry embers.
  • Know where fire extinguishers are and how to use them.
  • Practice extra safety with tools like welders, torches, and grinders. Flames and sparks from these tools can ignite dry material and wind can spread fires very quickly.
  • Parking is only allowed in designated areas, but on Red Flag Warning days it is even more important as car exhaust systems can easily ignite dry brush.
Employee Well-being

Our employees' health is a priority:

  • Those working outdoors should have access to shaded rest spots and should take regular breaks.
  • Adequate water is available to employees exposed to heat.
  • Training programs teach recognition and prevention of heat-related illnesses.
