Summer and fall in Houston are full of daily high-temperature records. In 2023, over 2,300 heat-related deaths occurred within the US, and with forecasts predicting even higher temperatures throughout the rest of the summer, the concern for heat-wave-related illness should be top of mind.

Construction workers, for example, are 13 percent more likely than those in the general population to suffer fatalities caused by heat-related illnesses. As the summer heat continues, safety must be a top priority for anyone working outdoors.

Prioritizing worker safety is paramount in our area where we experience an extended summer. The following tips will help business leaders and managers prioritize the health and well-being of workers.

Education

Developing a plan is the first step in creating a culture that prioritizes heat safety. To mitigate employee risk, regular education throughout the year should occur to help workers identify the signs of heat illness. In especially hot months, regular communication and monitoring throughout the day is paramount.

Environmental monitoring tools like the OSHA-NIOSH heat safety app should be a part of heat safety plans. The app helps leaders monitor temperature, humidity, and heat index on individual job sites. Additionally, wearable monitors that track vitals like heart rate can be invaluable for identifying signs of heat illness. However, these tools require thorough education to ensure effective use.

Flex Schedules

Working early in the day is an important and popular strategy in the summer months. It is impossible to avoid the heat completely, so providing cool areas, such as cool job site trailers for resting at breaks or meals can help keep employees from overheating. Additionally, Portacool units effectively cool the surrounding area by up to 30 degrees. These mobile devices can be used both indoors and outdoors, working by pulling hot air through a medium that causes water to evaporate. A fan then disperses the cooler air, creating a more comfortable environment for workers.

Heat acclimatization is crucial, especially for new outdoor crew members. Safety professionals should gradually increase their exposure to the elements to keep them healthy. It's also important to ease workers back into increased heat exposure after an extended absence.

Hydration

Proper hydration is essential for heat safety. Employees should be encouraged to take water breaks and drink electrolytes, with supervisors regularly reminding them to do so. Items like electrolyte ice pops can help maintain a healthy workforce on especially hot days. Body cool stations equipped with cold drinks, ice coolers, and cooling towels can effectively cool the body from the inside out. Offering various ways for employees to stay hydrated and cool demonstrates the organization’s commitment to worker well-being.

Heat safety is a critical concern. Preventing heat stress and illness relies heavily on preparedness, education, communication, flexibility, and hydration. Businesses employing outdoor workers must be aware of the dangers posed by heat and humidity, and the importance of recognizing signs of heat stress. Prioritizing heat safety ensures a safe summer and fall in Houston's challenging climate.

Houston's William P. Hobby Airport is generating its own clean energy.

Houston Aiports announced that Hobby's red garage is now home to a "solar canopy" that is producing energy at 100 percent capacity to power daily operations. The photovoltaic (PV) solar system generated more than 1.1 gigawatt-hours of electricity in testing, and is expected to produce up to 1 megawatt-hour now that it's operating at full power.

“This project is proof that sustainability can be practical, visible and directly tied to the passenger experience,” Jim Szczesniak, director of aviation for Houston Airports, said in a news release. “Passengers now park under a structure that shields their cars from the Texas sun while generating clean energy that keeps airport operations running efficiently, lowering overall peak demand electrical costs during the day and our carbon footprint. It’s a win for travelers, the city and the planet.”

The project was completed by Texas A&M Engineering Experiment Station (TEES) and CenterPoint Energy. It's part of Houston Airport's efforts to reduce carbon emissions by 40 percent over its 2019 baseline.

In a separate announcement, the airport system also shared that it recently reached Level 3 in the Airports Council International (ACI) Airport Carbon Accreditation program after reducing emissions by 19 percent in three years. This includes reductions at George Bush Intercontinental Airport (IAH), Hobby and Ellington Airport/Houston Spaceport.

The reductions have come from initiatives such as adding electric vehicles to airport fleets, upgrading airfield lighting with LED bulbs, adding smarter power systems to terminals, and improving IAH's central utility plant with more efficient equipment. Additionally, the expansion to Hobby's West Concourse and renovations at IAH Terminal B incorporate cleaner equipment and technology.

According to Houston Airports, from 2019 to 2023:

  • IAH reduced emissions by 17 percent
  • Hobby reduced emissions by 32 percent
  • Ellington Airport reduced emissions by 4 percent

"I see firsthand how vital it is to link infrastructure with sustainability,” Houston City Council Member Twila Carter, chair of the council’s Resilience Committee, said in the release. “Reducing carbon emissions at our airports isn’t just about cleaner travel — it’s about smarter planning, safer communities and building a Houston that can thrive for generations to come.”
