In Japan, fire dogs perform fire prevention and extinguishing services. There are 269 firefighters and two fire dogs in Shang Yue. The olfactory function of fire dogs is ten thousand times stronger than that of human beings. Trained fire dogs can jump over obstacles, identify items, guard items and arrest arsonists. They can also be used to detect the leakage of combustible gas, find people lost in high mountains, search for earthquake victims and rescue drowning people, so they are favored.
With the support of American Farmers Association, American Farm Fire and Accident Company began to train police dogs to detect arsonists. Trainers have found that trained police dogs can detect many combustible substances that are burning or unburned, even those covered with water, ice or garbage. At present, firefighters in more than 20 States in the United States have used police dogs to find evidence of arson, which is often recognized by the court, making it impossible for criminals to be exonerated when they are prosecuted. In order to reduce the huge losses caused by arson to farmers, the farmers' association will continue to support this work and let more fire brigades in the United States get such police dogs.
The British fire department began to use this method after successfully using police dogs to find arsonists in the United States. At present, the legality of evidence found by police dogs has been affirmed by law. There are many arson cases in Britain. In order to intensify the crackdown on arson, the British fire department began to adopt the American approach-training police dogs to find arsonists. They trained police dogs to sniff out flammable substances such as gasoline and paraffin. After about 200 trainings in half a year, these police dogs can accurately smell the arson in the fire and lead the staff to find the arsonist. In order to prevent dogs' paws from being injured by hot flames and sharp objects in the fire, British firefighters made special boots out of hard leather and nylon and put them on before entering the fire. At present, only the London Fire Department is equipped with such police dogs. Moreover, following the success of training police dogs to detect arsonists, the British police began to train police dogs to smell explosives and achieved success.
The British Fire Academy has also set up a dog training program. The Fire College is the only licensing institution for fire dogs in the UK. Fire dogs are tested once a year before they can renew their licenses. If the fire is too fierce and all the evidence on the scene is burned to ashes, the fire department will dispatch trained fire dogs. Domestic fire dogs have a more than 200 times more sensitive sense of smell than the most advanced electronic instruments, which can save a lot of time. Checking a four-bedroom house takes about 3-4 hours for electronic instruments and only 15 for fire dogs. Knowlton, a professor at South Bank University in London, recently confirmed that an excellent fire dog can even distinguish a billionth liter of gasoline fog. At present, the minimum evidence limit of the British court's judgment on arson is one millionth of a liter of combustible material. Even if combustible materials are mixed with other liquids, or combustible materials are burned with other articles with strong smell, they cannot escape the sensitive nose of fire dogs. The location determined by the fire dog, 30cm from Fiona Fang, will be the focus of evidence collection. /history/photo/2010-111258476.html This is a picture.
