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-based Quaise Energy, a producer of utility-scale geothermal power, raised $134 million in a Series B round to advance its “superhot” geothermal power plant.

Climate-focused San Francisco-based investment firm Prelude Ventures led the round, with participation from JERA Co., Japan’s largest power generation company, and Idemitsu Kosan, one of Japan’s largest energy companies. Nearly all existing investors, including cleantech-focused investment firm Safar Partners, participated in the round.

“We have backed Quaise since the beginning because we believed accessing superhot rock would unlock geothermal energy at a scale the world has never seen,” Mark Cupta, managing director at Prelude Ventures, said in a press release.

The startup expects more equity and debt deals to close “imminently.” Quaise has raised $230 million since its founding in 2018.

Quaise says some of the fresh funding will go toward building the world’s first commercial-scale “superhot” geothermal power plant —Project Obsidian in central Oregon. In addition, Quaise is earmarking money for continued development and commercialization of its millimeter-wave drilling system toward depths exceeding 5 kilometers (about 16,400 feet).

Quaise uses a millimeter-wave drilling system developed at the Massachusetts Institute of Technology to remove rock at depths and temperatures that aren’t economically feasible with conventional drilling. With this technology, Quaise can reach rock at temperatures of around 570 degrees to 930 degrees in most places worldwide, enabling construction of geothermal systems that rival fossil fuels and nuclear energy in power density and that rival renewables in cost.

“Our ambition is to power civilization with Earth's most compelling energy source. This round takes us from field-proven technology to first commercial revenues,” Carlos Araque, co-founder, president and CEO of Quaise, added in the release.

Quaise has demonstrated the capability of its millimeter-wave drilling system at its Central Texas test site, drilling more than about 330 feet through granite in 2025—the first time the technology penetrated basement rock at full scale in the field. The company is approaching a depth of about 3,300 feet at the same site.

Construction of Project Obsidian is underway at Oregon’s Deschutes National Forest. The project, which has the potential to generate gigawatt-scale power, is slated to deliver electricity to the Pacific Northwest grid by 2030.
