Canines within the USAR environment - By Morné Mommsen
Urban search and rescue (USAR) K9 units and K9 mantrailing/tracking units serve different roles and environments.
USAR K9s specialise in urban and disaster settings, using air scent detection to locate any human scent in complex, hazardous environments. They are trained for agility and navigating debris, providing quick coverage of large areas.
In contrast, K9 mantrailing/ tracking units focus on following the specific scent trail of an individual based on a scent article, using scent discrimination and ground scent tracking across various terrains. These units are often deployed in wilderness search and rescue, criminal investigations and missing person cases.
The primary differences lie in their scent focus, operational environments, training techniques and alert methods.
Primary focusSearch and rescue in urban and disaster environments: USAR K9s are trained to operate in complex, often hazardous environments like collapsed buildings, debris fields and other disaster-stricken areas.
Training and skills• Air scent detection: USAR K9s primarily use air scenting to locate any human scent in their vicinity, without needing a specific scent article. They are trained to detect human scent particles in the air, which is useful in open or confined spaces filled with rubble.
• Agility and navigation: These dogs are skilled at navigating unstable and hazardous terrains. They can climb over debris, enter confined spaces and move through obstacles safely.
• Bark alert: When they find a person, they typically indicate the discovery by barking, which alerts their handler and the rest of the rescue team. The K9s are specifically trained to react to “live” scent and to ignore human remain or the deceased. That is why we don’t make use of a multi-skilled trained canine. Either trained in live scent or trained in HRD but not both disciplines.
Operational environmentDisaster sites: USAR K9s are deployed in environments affected by natural disasters such as earthquakes and hurricanes or man-made disasters such as building collapses and explosions. Quick coverage: They are used to quickly cover large, complex areas to locate survivors who might be trapped or buried.
K9 mantrailing/trackingPrimary focus: Following a specific human scent trail: Mantrailing and tracking K9s are trained to follow the scent trail of a specific individual based on a scent article eg a piece of clothing.
Training and skills• Scent Discrimination: These dogs are highly skilled in scent discrimination, allowing them to focus on the unique scent of the individual they are tracking, ignoring other scents.
• Ground Scent Tracking: Mantrailing and tracking K9s often follow ground scent, which includes skin cells, sweat, and other microscopic particles left by the person on the ground and vegetation.
• Trailing Behaviour: They may follow a trail that has aged, depending on the conditions and can often distinguish the scent of a specific person even in crowded or heavily trafficked areas.
Operational environment• Various terrain: They can work in diverse environments, including urban areas, forests, rural regions and any location where a person might travel.
• Long-distance tracking: These dogs are used for tracking over potentially long distances and periods, such as in search of missing persons, fugitives or lost hikers.
Key differences• Scent focus:- USAR K9s: Use air scenting to locate any human scent in disaster environments.
- Mantrailing/tracking K9s: Follow a specific individual’s scent trail based on a scent article.
• Operational environments- USAR K9s: Operate mainly in disaster and urban search and rescue scenarios, often involving hazardous and unstable environments.
- Mantrailing/tracking K9s: Work in a variety of environments and are often used in wilderness search and rescue, criminal investigations, and missing person cases.
• Training and techniques- USAR K9s: Trained for agility, navigating rubble and quick area searches, with a focus on air scenting.
- Mantrailing/Tracking K9s: Trained for scent discrimination and following ground trails over potentially long distances.
• Alert methods- USAR K9s: Typically use bark alerts to indicate the presence of a human.
- Mantrailing/tracking K9s: Indicate the trail or the person in various ways depending on their training, often by leading the handler directly to the person.
Understanding these distinctions helps in deploying the right type of K9 unit for specific search and rescue missions or law enforcement tasks.
In Urban Search and Rescue (USAR) teams, K9 (canine) units play a crucial role, particularly in reconnaissance operations.
The importance of reconnaissance for USAR K9 handlers and the necessity of specialised training in rubble areasUrban Search and Rescue (USAR) teams play a critical role in responding to disasters, both natural and man-made, where quick and effective action can mean the difference between life and death. Within these teams, K9 units are invaluable assets, providing capabilities that human rescuers cannot match. For USAR K9 handlers, reconnaissance is of paramount importance, enabling them to optimize their search efforts and ensure the safety and efficiency of the operation.
Additionally, training canines specifically for USAR rubble areas is essential to equip them with the specialized skills required for these challenging environments.
The importance of reconnaissance for USAR K9 handlersReconnaissance provides USAR K9 handlers with essential information about the disaster site, allowing them to assess the environment comprehensively. This assessment is crucial for identifying potential hazards such as unstable structures, hazardous materials, and other dangers that could threaten the safety of both the K9 units and the rescue team. By understanding these risks, handlers can plan search strategies that mitigate danger, ensuring that K9s are deployed in the most effective and safest manner possible.
Locating survivors quickly is the primary objective of any USAR operation. Through reconnaissance, handlers can prioritize areas where survivors are most likely to be found, making search efforts more targeted and efficient. This prioritization is vital in disaster scenarios where time is of the essence, as it allows for a rapid
response that can significantly increase the chances of finding survivors alive.
Efficient resource management is another critical aspect of reconnaissance. By gathering detailed information about the site, handlers can manage the deployment of K9 units more effectively, preventing exhaustion and ensuring that the dogs are utilized where they are most needed. Additionally, reconnaissance information facilitates better coordination with other rescue teams, avoiding duplication of efforts and ensuring that all available resources are used to their fullest potential.
The safety and welfare of the K9 units and their handlers are paramount. Reconnaissance helps ensure that K9s are not sent into unnecessarily dangerous areas without adequate precautions. This consideration not only protects the dogs but also ensures that handlers can safely navigate the site while working with their K9 partners. In a high-risk environment, the well-being of both the K9s and their handlers is essential for maintaining the effectiveness of the rescue operation.
The necessity of specialised training in rubble areasTraining canines specifically for USAR rubble areas is crucial due to the unique challenges these environments present. These areas require specialised skills that go beyond standard search and rescue training. One of the primary skills needed is agility and navigation. USAR environments are often characterised by unstable and uneven terrain, necessitating that K9s be proficient in climbing, balancing and manoeuvring through debris. This physical adaptability is essential for locating survivors in complex and hazardous conditions.
Scent work in rubble areas is another critical skill. The scent dynamics in such environments are complex, with human scents potentially being trapped or diffused by the debris. K9s must be trained to effectively locate scents under these challenging conditions. Realistic training scenarios that simulate actual disaster sites help prepare the K9s for the sights, sounds and smells they will encounter, ensuring they remain focused and effective during real operations.
Desensitisation to stress and chaos is another important aspect of training. Exposure to rubble environments during training helps K9s manage the stress associated with high-stakes search and rescue operations. This exposure builds the dogs' confidence and ensures they can perform reliably under pressure. Furthermore, repeated training in these conditions enhances the coordination and communication between handlers and their K9s, fostering a seamless partnership crucial for effective search and rescue operations.
Reconnaissance is essential for USAR K9 handlers to plan and execute search operations effectively and safely. It enables handlers to assess hazards, optimise search efforts, manage resources efficiently and ensure the safety of both the K9s and the rescue team. Additionally, training canines specifically for USAR rubble areas equips them with the necessary skills to navigate and operate in these challenging environments. This specialised training ensures that K9s can perform their tasks efficiently, ultimately enhancing the overall success of USAR missions.
In summary, using multiskilled trained canines for Urban Search and Rescue (USAR) operations is not recommended due to the need for specialised training, performance optimisation, safety concerns and operational consistency. USAR canines require focused training to navigate hazardous environments and perform specific tasks effectively.
Specialising ensures that these dogs can operate safely and efficiently under the unique pressures of disaster scenarios, enhancing the overall success of rescue missions.
