In this week’s First Responders Spotlight, we head to a fire station that helped a couple stay together in the final years they had left, RochesterFirst.com reported.

Henrietta Fire District managed to provide a level of security and peace for John and Jodi Guiancursios, husband and wife, when emergencies arose, the report said.    

John Guiancursios was in failing health in the final years of his life, getting weaker and suffering from dementia, the report said.

Not wanting to live in a nursing home, John was able to stay in his Henrietta home, right across the street from the Erie Station Fire Department, part of the Henrietta Fire District. John would often collapse and have emergencies and Jodi would call the fire team for help, according to the report.

The fire department helped the Guiancursios as much as 20 times, the report said.

While John passed at 87, what these firefighters did for him and Jodi remains. The fire team wants to let everyone know they don’t just fight fires.

Thermal Imaging Manfred Kihn

In my article “What Am I Looking At?” (August 2022), I reflected on the use of grayscale imagery with white-hot polarity (white—hot, black—cold, everything else—shades of gray) while using your thermal imager (TI). This month, I want to expand on this more by talking about colorization and temperature measurement.

All TIs will produce colorization. This is a standard feature at different temperature levels based on their respective manufacturer specifications. National Fire Protection Association (NFPA) 1801, Standard on Thermal Imagers for the Fire Service–2021 Edition, stipulates that only the colors of yellow, orange, and red can be used. For example, this manufacturer inserts colorization at this temperature range: Yellow 500-800°F (260-426°C), Orange 800-1,000°F (426-537°C), Red 1,000+°F (537°+C).

What the NFPA does not stipulate is what temperature this colorization should appear. Therefore, all manufacturer specifications can vary, so make sure you understand this before use.

What does colorization do for you?

As the temperature progresses within the structure, your TI will produce colorization indicating concerns: extreme ceiling temperatures, advancing fire progression, the location of the fire, and so on. Each color palette will give you a certain temperature range. Remember, this colorization is only temporary, because as soon as you get water on the fire, the red goes away, and your TI is back to showing grayscale imagery. Some TI technology have user selectable modes, which insert distinct color palettes based on various applications you require, so make sure you understand which application your TI should be set on.
