Why do the firefighters tear open walls even though it doesnt seem like there was fire in a room?
• Fire often travels up inside of walls and can go undetected for a long time. Fires that are left undetected can re-ignite several hours later and cause extensive damage to a structure. Thermal imaging cameras are used to help firefighters detect heat inside of walls using infrared technology which helps to eliminate the need to cut so many holes.
