This month features the fifth and final part of this series. Hopefully, you have found these columns useful, as they consist of different applications or approaches to using thermal imaging as well as tactical techniques.
As with anything that we do in the fire service, proficiency only happens with continuous practice. This month, we will talk about medical assessment, maintenance, outdoor search and rescue, the spot temperature heat indicator, and field of view.
MEDICAL ASSESSMENT
A thermal imager (TI) is a great tool to use on medical runs for a rapid assessment to quickly identify patients with a higher or lower body temperature, which can be an indicator of illness; infection; and heat-related, cold-related, or lack of blood circulation conditions. Consider using a TI at mass-casualty incidents to help determine injuries and for reduced risk, as a TI eliminates the need for physical contact, which reduces the risk of cross-contamination and patient-to-patient infection transmission.
Note that using a TI does not make you a doctor. Follow your regular medical protocols for patient assessment, as thermal imaging data should not be relied on solely. Medical professionals must use clinical judgment to determine patient care. Fire service personnel must receive training on the proper use of TIs for medical assessment.

MAINTENANCE
Maintaining a fire service TI is crucial to ensure its reliability and effectiveness in emergency situations. Following are the key steps and best practices for maintaining a TI.
- Regular exterior cleaning: Use a soft cloth and mild soap solution to clean the TI’s exterior casing. Avoid using harsh chemicals. Isopropyl alcohol works great for removing those stubborn stains. For cleaning the front lens, use a microfiber cloth or lens-cleaning solution to carefully clean the lens. Ensure no debris scratches the lens during cleaning.
- Software updates: Regularly check and update the TI’s software or firmware. Manufacturers often release updates that improve performance or add features.
- Battery maintenance: Keep batteries charged according to manufacturer guidelines. Regularly inspect batteries for signs of wear or swelling and replace them when needed.
- Functional checks: Perform regular operational checks to ensure the TI is functioning properly. Test all features including different modes (if applicable) and temperature ranges. Conduct a visual inspection of the device for any physical damage or signs of wear and tear. Don’t forget the display screen (screws) and any side or carry straps, and check the operation of the charger. All TIs are man-made, battery-operated, and electronic pieces of equipment that can fail if not properly maintained.
Always refer to the user manual provided by the manufacturer for specific maintenance instructions tailored to your TI.
OUTDOOR SEARCH AND RESCUE
Using a TI for outdoor search and rescue operations can be an invaluable tool for fire services, emergency responders, and search and rescue teams. Following are some
