National Heat Awareness: Ways to Stay Cool on the Jobsite

Reading Time: 4 minutes

As the spring season winds down and temperatures steadily rise, outdoor working conditions may feel more intense than usual. According to the Occupational Safety and Health Administration (OSHA), every year, thousands become sick while working in extreme heat or humidity, and dozens succumb to the harsh conditions. To spread awareness, OSHA created the Heat Illness Prevention Campaign and recognizes National Heat Awareness Day on the last Friday in May each year.

Signs to watch out for

OSHA reports that people with pre-existing health conditions are at higher risk of being affected by extreme heat conditions, but no one is immune. Personal risk factors also include medications, physical characteristics (i.e., age, pregnancy, and fitness level), and behavioral characteristics (i.e., alcohol or drug use and water intake).  

Here are some signs of distress that can occur in extremely hot conditions:

  • Heavy sweating: This symptom is more likely to go under the radar because — who doesn’t sweat in the heat? But if you’re sweating out water faster than you can replenish it, this could become an early symptom of heat-related exhaustion and illness.
  • Tiredness or weakness: Feeling worn down is another symptom that could be considered typical for a day on the job — but muscle cramps, fatigue, weakness, and dizziness can indicate overheating.
  • Headache or nausea: Headaches and nausea are some serious symptoms of a potential heat stroke where medical attention is needed as soon as possible.
  • Abnormal behavior, slurred speech, seizures, or passing out: If you notice yourself or a fellow worker slurring their speech, behaving in unusual ways, or losing consciousness, get medical help immediately. These are the most severe symptoms of heat stroke and are indicators of a medical emergency.

Prevention

While we can’t control the weather, we can prevent medical emergencies during extreme heat. Here are some practical steps to stay safe on the jobsite:

  • Ease into outdoor work. The Centers for Disease Control (CDC) emphasizes the importance of acclimatization to prevent heat-related illnesses. When the weather gets hot, don’t jump straight into a full workday outside; gradually increasing your exposure to hot temperatures will help your body adjust more safely.
  • Take breaks. Give yourself time in a cool, shady location at frequent intervals for your body to recover before continuing to work in hot, humid environments.
  • Wear clothing and gear that minimizes heat stress. There’s a variety of gear for the jobsite to help prevent symptoms of heat exhaustion before they start. Professionals can beat the heat with a variety of cooling products from Klein Tools at City Electric Supply (CES).

Be aware & prepared

The dangers of extreme heat can sneak up on anyone, especially when working outdoors. Remember to always listen to your body. Drink more water, even if you don’t feel thirsty. Take breaks frequently in a shady area with fans and cooling bands. If you feel light-headed or nauseous, take precautions and call for help. Be aware and stay prepared in the summer heat.
