Ignitable Liquids vs. A Liquid that will readily ignite when exposed to an ignition source. Leaves traces of Ignitable Liquid Residue (ILR) Example: Gasoline Accelerants Material that is used to increase the rate of combustion for materials that do not readily burn. Does not leave traces of ILR. Example: Propane gas Copyright 2014 Fire K9.org

Is estimated to be 100,000 times keener than a human. Can detect as little as one micro liter (1000 th of a drop) of an ignitable liquid. Can detect odors 20-40 feet underground. Canine olfactory bulbs weigh about 60 grams (four times as much as a human.) Can distinguish odor “layering.”

Source= Wet Nose. Mucous & cilia trap odor molecules and dissolve them. Scent receptors send a signal along tiny nerves (axons) and olfactory nerves that sends a message from olfactory bulb to the brain, interpreting smells. When nostrils are flared to sniff, shape of the nostril opening changes and redirects air to upper part of the nose to sensory cells. Canines can detect which nostril has strongest concentration of scent. The average dog produces about one pint of mucous per day. Copyright 2014 Fire K9.org

MechanicalCanines Difficulty detecting tiny amounts of ILR - differs by mfg (Parts per billion.) Need to be calibrated before use according to mfg specifications. Storage or on-scene temperature variations can cause false readings. Short life span (1-2 years) – sensors degrade in time whether used or not. Constantly needs to be exposed to fresh air/zero reading to burn off contaminants between probes. Fresh batteries always needed. Can detect 1-5 micro liters. No calibration issues – Canines rarely have an “off” day. Temperatures don’t cause false alerts. 7-10 year working life span depending on canine. Not applicable. Never need batteries!
