For those of you who have been in the fire service for more than 15 years, like I have, you most likely remember a time when a thermal imaging camera (TIC) was considered a luxury tool.
Many fire departments couldn’t afford the technology, and those that could purchase a TIC didn’t fully understand how to effectively use the tool. Today, the use of thermal imaging technology is readily accepted in the fire service as a lifesaving tool that protects firefighters from unseen dangers. I’m grateful for this opportunity to share my TIC knowledge with you each month by exploring a variety of TIC topics from firefighter disorientation to search and rescue to overhaul and much more. Together, we will explore the benefits a TIC can bring to a firefighting crew at the fire scene.
My responsibility as a trainer is to arm firefighters with an in-depth understanding of thermal imaging technology and its benefits to the fire service. My training is designed to teach firefighters how to interpret what this life-saving tool is telling them so they stay safe at a fire scene. I encourage you to share with me your experiences using a TIC and any questions you have about this technology. The more we share with each other our experiences using this technology, the safer we will be when responding to a call.

BASIC TERMS
Let’s go back to the basics of thermal imaging and examine infrared (IR) energy and solar loading. Emissivity (E) is a measure of a material’s ability to absorb and emit IR energy. Conversely, reflectance (R) is a measure of a material’s ability to reflect IR energy. Good reflectors are not good emitters and vice versa. Good reflectors appear to be the same temperature as their surroundings.
Emissivity and reflectance values range from zero to one, but in general, we only refer to a material’s emissivity value. High emissivity values (i.e., close to 1) indicate that a material emits IR much more than it reflects it. (See box for some examples.) Railroad tracks, for example (photo 1), that are active will have a low emissivity value as they would be shiny and therefore not retain much heat from the sun.

All departments keep some type of data. The most commonly referred to data are the number of runs and response times. But there are a lot more data we should be capturing and sharing to help sell our communities on the need to be funded so we not only survive but thrive.
I recently had the privilege of attending a presentation titled “Counting Calls” by Dr. Lori Moore-Merrell, assistant to the president of the International Association of Fire Fighters (IAFF) in charge of data, research, and technical assistance. The presentation was about data and how we need to capture and use more data to show our value to the community. The topic might not seem as engaging as firefighting tactics or lights and sirens. But, acknowledging that documenting our activities is not how most of us prefer to spend our time, her presentation made data collection a most compelling task we must embrace.
TOTAL VALUE
The basic premise is that we need to show our total value in a quantitative manner. Quantitative data will almost always win out over subjective and emotional debates when it comes to justifying funding. This applies to funding for stations, apparatus, equipment, staffing (career and volunteer), and support (such as annual physicals) for fire department members. It has been said many times, true, that the side with the best data usually wins. A key point in Merrell’s presentation was that we must quantify other activities in addition to call response. In addition to number of calls, many departments also track dollars lost because of fire, dollars saved because of suppression, number of smoke detectors installed, and other “low-hanging-fruit” types of activities.
However, we must tell a more complete story of what we do and, maybe more importantly, what we can’t do—i.e., our limitations because of a lack of funding for our service needs. For example, a volunteer fire department needs quantifiable data on the amount of time it averages to assemble an effective firefighting force to suppress a fire—think two in, two out. The community needs to know if its department might not be able to safely implement an interior search and rescue for extended minutes because of a lack of staffing. Department leaders must be up front and say that they can only protect exposures and conduct defensive operations with limited staffing. For career departments, there must be clear and accurate data that show how many calls a company misses during a year because it is on other calls. This is referred to as “system capacity.” I retired from a department that, like many departments, can easily run out of resources during a thunderstorm. The community should also be reminded that response times apply to emergency medical service calls, especially CPR, as well as fire calls.
TRUE DATA
Data collection and reporting must be “true.” Unfortunately, there is inconsistency in reporting “true” response times. Some departments track response times as the time the apparatus leaves the station until it arrives on the scene. However, “true” response time is the time the call is received, not dispatched (as this ignores call processing time), until action is taken on th
