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.

Rice University researchers have uncovered a more energy-efficient and faster way to recycle critical minerals from used lithium-ion batteries.

Traditional methods rely on high heat, long processing times and harsh chemicals to recover a small fraction of critical materials from batteries used in everything from smartphones to electric vehicles. However, the team from Rice's Department of Materials Science and Nanoengineering developed a process that uses a water-based solution containing amino chlorides to extract more metals in less time

The team published the findings in a recent edition of the scientific journal Small.

Simon King, a sophomore studying chemical and biomolecular engineering who completed this work as a summer research fellow at the Rice Advanced Materials Institute, served as first author of the study. He worked with corresponding authors Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering, and Sohini Bhattacharyya, a research scientist in Ajayan’s lab.

By using a hydroxylammonium chloride (HACI) solution, the team achieved roughly 65 percent extraction of key battery metals in just one minute at room temperature, according to the study. The efficiencies grew to roughly 75 percent for several metals under longer processing times.

“We were surprised by just how fast the reaction occurs, especially without the involvement of high temperatures,” King said in a news release. “Within the first minute, we’re already seeing the majority of the metal extraction take place.”

By not requiring high temperatures or long reaction times, Rice predicts the process could have a major impact on cost and the environmental impact of lithium battery recycling. Additionally, the water-based HACI solution makes waste handling easier and lowers certain environmental risks.

In addition to extracting the materials, the team went on to demonstrate that the recovered metals could be recycled and reprocessed into new battery materials.

“A big advantage of this system is that it works under relatively mild conditions,” Ajayan added in the release. “That opens the door to more sustainable and scalable recycling technologies.”
