Concerns are growing for the safety of people who work outdoors as temperatures keep getting hotter.

Temperatures have already broken records. The last time New Jersey hit the 100-degree mark was this time last year, which is around when a 49-year-old construction worker died in Madison because of the heat.

According to the U.S. Labor Department, heat has killed more than 400 workers over the past decade.

Numbers like that are what fuel organizations like Make the Road New Jersey to get a heat standard implemented in the Garden State. This includes small steps, like making sure employees are taking water breaks and that water is available and free at job sites.

Nedia Morsy, the director of Make the Road New Jersey, is trying to get legislation passed in New Jersey.

"There have been heat-related deaths and that’s something we’re trying to avoid. We’ve heard reports where in the event of heat-related illnesses where employees were asked to go back on the floor and then later passed from heatstroke," Morsy said.

News 12 spoke with Dr. Cory Smith, a board-certified emergency room doctor and medical director for 24/7 Care at Teladoc Health, about symptoms of a heat-related episode and how to avoid one.

"When you see people that are complaining of headache, feeling fatigue, feeling dizzy, their heart rate is elevated, they’re feeling exhausted and they’re not sweating - that’s a big indicator that that individual is in trouble. We want to make that we’re drinking, [wearing] light clothing, loose clothing - making sure that if we can, we can sip slowly throughout the day,” Smith said. “If you’re thirsty, it’s too late. With that light clothing or that light cloth wet that and put it on us and that would help us dissipate heat.”

Make the Road New Jersey says it will be canvassing work sites this summer, so workers know their rights.
