The Department of Homeland Security, Science and Technology Directorate (S&T) recognizes that a dog's sense of smell is a million times more sensitive than a human’s. Canines can be trained to detect a wide variety of specific odors, such as explosives, humans, drugs, and even fruits and vegetables. Dogs are trained to alert to the presence of these odors with a learned response such as sitting or lying quietly.

DHS OHA Announces Release of IED and Active Shooter Guidance for First Responders

As part of our mission, the DHS Office of Health Affairs works to ensure that first responders around the nation have the tools, information and resources they need to respond to incidents in their communities. In recent years, improvised explosive device (IED) and active shooter incidents reveal that some traditional practices of first responders need to be realigned and enhanced to improve the survivability of victims and the safety of first responders caring for them. To this end, OHA has drafted and released the “First Responder Guidance for Improving Survivability in Improvised Explosive Device and/or Active Shooter Incidents” to help address this issue.
