Summer events bring big crowds, great energy, and memorable experiences. High temperatures can also create real health and safety risks. Heat-related illnesses can develop quickly, but they're also highly preventable with the right planning and preparation. By putting proactive safety measures in place and adjusting activities as weather conditions change, event venues can significantly reduce the risk of a serious heat-related emergency.

Here are five essential strategies to keep people safe.

1. Develop a Heat Safety Plan Before Temperatures Rise

Every venue should have a written heat illness prevention and emergency response plan. At minimum, it should define:

• When events will be modified or canceled based on weather conditions
• Who is responsible for monitoring heat conditions
• Who has the authority to decide on canceling or modifying the event
• Emergency procedures for suspected heat illness
• Staff training requirements

Being intentional and proactive is one of the most effective ways to prevent serious heat-related illness before it starts.

2. Schedule Wisely, and Prioritize Hydration and Cooling

Move strenuous activities, performances, and setup or teardown work to cooler parts of the day when possible.

Put free drinking-water stations throughout the venue, especially near high-activity areas, and encourage regular hydration. Make sure attendees know how to find water and how to get medical help if they need it.

Use shaded seating, air-conditioned or cooled indoor areas, fans where appropriate, and clearly marked cooling and rest zones.

3. Train Staff to Recognize and Respond to Heat Illness

Staff should know the symptoms of heat exhaustion and heat stroke, and have a clear process for getting medical help fast.

Early signs of heat exhaustion include:

• Heavy sweating
• Muscle cramps
• Dizziness
• Headache
• Nausea
• Weakness

Heat stroke is a medical emergency. Warning signs include confusion or altered mental status, collapse with or without loss of consciousness, and hot skin.

If heat stroke is suspected, call 911 immediately and begin rapid cooling while you wait for emergency medical personnel to arrive.

4. Protect Workers and Contractors

Event venues typically focus on the guest experience, but event staff carry some of the highest heat risk. Parking attendants, security guards, food vendors, and setup crews are often exposed to extreme heat for hours at a time. Give staff and contractors real breaks, cooling areas, and hydration, and make sure everyone is trained to help themselves and each other. OSHA and many states have specific rules around heat safety for employees, so it's worth checking what applies to your venue.

Workers who aren't used to the heat face the highest risk. Giving new or returning employees time to acclimate lets the body adjust to hot weather gradually, which meaningfully lowers the risk of heat illness.

5. Monitor Conditions Continuously, and Be Ready to Adjust

Venues should track temperature, humidity, and heat index before and during both outdoor and indoor activities. High humidity makes heat far more dangerous, because it limits the body's ability to cool itself through sweat.

If conditions turn dangerous, be ready to move activities to a cooler part of the day or cancel them outright. Limiting alcohol consumption can help too, since alcohol speeds up dehydration.

Your venue's heat plan should spell out exactly who has the authority to change or stop an event once conditions become unsafe.

Prevention Is the Real Strategy

Knowing how to respond to a heat illness emergency matters. Preventing one in the first place matters more. With a clear heat safety plan, smart scheduling, proper hydration, trained and protected staff, and ongoing weather monitoring, venues can create a safer experience for everyone who walks through the gates.
