Severe weather events like thunderstorms and tornadoes can cause power outages, flooding, and electrical surges that threaten medical devices. If you rely on life-sustaining equipment such as oxygen concentrators, ventilators, or insulin pumps, it’s crucial to prepare for unexpected emergencies. The U.S. Food and Drug Administration (FDA) provides essential guidelines to help you keep your medical devices safe during storms.

Medical Device Safety Tips for Thunderstorms and Tornadoes

Before the Storm: Essential Preparation

• Have a backup power source – Many medical devices require electricity, so ensure you have battery backups or a portable generator ready. Contact the device manufacturer to confirm the best alternative power options.
• Surge protection is key – Lightning strikes can cause power surges that damage medical equipment. Use surge protectors or unplug devices before the storm.
• Create an emergency medical kit – Include extra batteries, medical supplies, and waterproof storage for prescriptions. If you rely on refrigerated medications, prepare an insulated cooler with ice packs.
• Inform your power company – If you use electric-powered medical equipment, notify your electric company in advance. Some areas offer priority power restoration for individuals with medical needs.

During the Storm: Staying Safe with Medical Devices

• Move devices to a safe space – Strong winds and tornado debris can damage equipment. Store portable medical devices in a secure, enclosed area.
• Use generators safely – If you need a generator during a power outage, operate it outside and away from windows to prevent carbon monoxide poisoning.
• Check battery levels – Monitor the battery life of your oxygen concentrator, CPAP machine, or glucose meter to avoid unexpected shutdowns.

After the Storm: Assessing Damage to Medical Equipment

• Inspect devices for water damage – Flooding from storms can contaminate medical equipment. Do not use wet devices until approved by a healthcare provider or manufacturer.
• Verify device settings – Some medical devices reset after a power outage. Double-check that ventilators, insulin pumps, and oxygen machines are functioning correctly.
• Monitor water safety – If your medical device requires water (e.g., home dialysis, CPAP machine), use only clean, uncontaminated water.

Special Considerations for Blood Glucose Meters & Insulin Pumps

• Keep test strips dry – Humidity and flooding can affect the accuracy of blood glucose meters. Store test strips in their original sealed container.
• Watch for temperature damage – If insulin is exposed to extreme heat, it may lose effectiveness. Store it in a cool, dry place post-storm.

Thunderstorms and tornadoes can strike unexpectedly, but advance preparation can keep your medical devices functional and safe. By securing backup power, protecting against flooding, and maintaining emergency supplies, you can ensure continued medical care even during extreme weather.
