America has seen record-setting heat over the past few summers, putting tens of millions of people, as well as the public safety professionals who care for them, at risk of heat emergencies. As the mercury rises, conditions become dangerous for anyone working outdoors or living in a residence without air conditioning.

As you prepare for a heatwave in your community, here are a few things to keep in mind.

Personal safety in high-heat conditions

  • Physical training: Schedule outdoor PT early in the morning or late in the afternoon. If you can’t beat the heat outdoors, workout indoors or take a couple of days off for more sleep – you probably need it.
  • Hydration: Thirst is the best indicator to take a drink of water. Take a drink when you are thirsty. Pale or clear urine is another useful indicator of adequate hydration. If you are anticipating high-exertion, outdoor activity, pre-hydration may be useful, but not to the point of feeling full or bloated. Bring extra water in your vehicle in case you are unable to get back to the station.
  • Electrolyte replacement: Sports drinks are useful for replacing electrolytes during and after long durations of aerobic exercise, but they often contain empty sugar calories you may not need. Quench your thirst with water and replace electrolytes with a well-balanced diet before turning to sports or energy drinks.
  • Manage the scene: As conditions allow, move suspects or bystanders you are interacting with into the shade, air-conditioned vehicles, or buildings.
  • Enhance cooling: When the ambient air temperature is in the high 90s or 100s, passive heat loss is ineffective, so enhance cooling with misting fans, ice packs, cooling towels, or immersion.
  • Watch your partner: Your human or K-9 partner is also at risk when the temperatures climb. Early signs of dehydration, heat exhaustion and heat stroke include lethargy, confusion and other personality changes. If your partner seems “off,” take a water break out of the sun and humidity, and consider additional assessment of their pulse rate, respiratory rate, mental status and recent water consumption.

Heat safety for your community

  • Check on vulnerable populations: The elderly and people experiencing homelessness are at increased risk during high-heat and -humidity conditions. Some medications, as well as the aging process, compromise an older person’s ability to thermoregulate. The St. Charles County Ambulance District used a Costco grant to give seniors cold water and heat safety tips.
  • Provide community education: Use department social channels, media outreach and face-to-face visits to discuss heat emergency signs and symptoms, prevention and emergency care. Consider partnering with your public health department to deliver formal or informal education programs to outdoor employers, such as construction and landscaping businesses, and youth sports camps.
  • Open cooling centers: A cooling center is a community building, school, or business that opens its doors and shares its air conditioning during extreme heat events to people who lack air conditioning in their home. An ambulance crew may be formally assigned to the cooling center, but it is also an opportunity for informal visits from community police officers or for firefighters to conduct community risk reduction programs. Relationship building and education are always valuable.

Worsening impact of climate change on public safety


Public safety personnel will continue to feel the impact of more frequent and more severe weather events on the calls they respond to, the equipment they need to replace or purchase, and the costs and complexity of building severe-weather hardened stations and communication centers.

Here are examples of initiatives to reduce the impacts of climate change:
