Some fire departments use doggos in order to find out the cause of the fire. A recent study shared that doggos can actually detect traces of gasoline even if it is only one billionth of a teaspoon.
– Two doggos were trained to smell accelerants.
– One of them was trained to particularly smell gasoline.
– The two dogs were able to detect a billionth of a teaspoon of gasoline.
The University of Alberta chemists came up with this study in order to boost the possibility of training more doggos to be part of fire departments or police departments handling arson cases. The lead author of the study, Robin Abel, said that, “During an arson investigation, a dog may be used to identify debris that contains traces of ignitable liquids — which could support a hypothesis that a fire was the result of arson.” The chemists used two teams of dog-and-handler for their study. One dog was trained on a number of ignitable liquids while the other dog was trained to sniff only gasoline.
The first dog performed well in detecting all types of accelerants while the second dog could not detect the other accelerants at extremely low volume. Both did well in detecting only a billionth of a teaspoon of gasoline. James Harynuk, associate professor of chemistry and Abel’s supervisor, said, “Their noses are incredibly sensitive.”
