Another great session Thursday evening. Earlier in the night we experimented with critical spacing and came up with some interesting thoughts. We also passed around the FLIR towards the last portion of our training and made some new observations.
We met at the south end of Ave K at the old Sanatorium site in Saskatoon. An interesting mix of terrain. Although the bulk of our session was held in what might be considered typical open prairie, we also spent a considerable portion of our session in dense brush.
Our team started by attempting to determine the critical separation based on a dark coloured ladies shoe. By dropping the shoe down on the ground and gradually walking away from it we established the approximate spacing. So far so good ... Search basics 101! Things gradually got more interesting.
After forming our search line a team member in my group tossed the shoe far into the distance while our backs were turned. We designated a team leader and began to slowly march forward at what would be considered a TYPE 2 search.
We experimented with two different colours of light. Red did not seem to be nearly as effective as the white light. We decided to use white lights on our headlamps along with our flashlights for the search.
It was apparent that the probability of detection significantly increased with light intensity. That would seem logical, but an interesting question came to mind. If the four of us on a search line are all using flashlights with large differing outputs should that influence the critical spacing? In other words, If one of us was carrying an extremely bright light should there be a large gap at that point in the line? If one can achieve the same Probability Of Detection but cover a larger gap because of the intensity of light, is this appropriate? A conversation took place. We ended up deciding that we would all keep the exact same critical spacing for now. I still wonder if this is the most effective thing to do?
Later that night we passed around the FLIR. We started by looking at the range of this unit and it does present a new way of searching. After some simple tests, it was decided that a particular colour motif (the FLIRs thermal representation) of defining temperature worked best on a setting called iron. I am sure opinions will vary as we all process these things differently. It did seem to work well for me though.
After finishing with the range tests, we decided to send a few members into the woods with a five minute head start. What we found was that the tool still needs some refining to figure out the most useful way it could be used in a search. Its worth mentioning that Rebecca pointed out that perhaps by placing the FLIR in advance of a search team it might significantly increase the POD. The unit seems to cover the same area as a four person team based on prior experiments. Its by no means perfect, but with a little more thought I think we may be able to successfully integrate this into our operation and add to our overall efficiency.
As it got later into the night, two teams were tasked with applying hypothermia wraps independently on separate people. We used the FLIR to inspect the completed wraps to look for heat loss. It would seem that this is a very good tool for this purpose. A large difference was noted between the two different groups. A quick scan of each wrap immediately showed issues which could have been quickly remedied.
This night provided many lessons for all of us. The value of regular training continues to refine and influence our methodology.

Reflections on the SARVAC workshop held in Saskatoon
This past weekend I attended the National SARVAC Workshop in Saskatoon. As a new SSAR recruit, I wasn't sure what to expect. The weekend was filled with many engaging opportunities to meet with other volunteer SAR professionals across Canada. I experienced many moments of profound admiration for the organization as the conference evolved.
One of the images etched into my mind was the quiet confident glow of our longtime outgoing National SARVAC president Harry Blackmore. I regret not sitting down and having a conversation with him. His demeanor was reminiscent of a man that has successfully navigated several layers of local, provincial and federal government with unwavering persistence. His leadership has positioned our organization with a sustainable level of support which will serve Canadian citizens far into the foreseeable future.
Scott Wright is now the new president. Scott had many opportunities to speak as he was one of the key people driving the workshop to a successful conclusion. Although I had very limited exposure to him, it was easy to see that he is a friendly knowledgeable person with the natural ability to lead. He created a comfortable environment for all of us to mix and share ideas.
I spent a significant amount of time getting to know the Saskatoon Search and Rescue contingent. I learned some valuable lessons. First, I was issued my first orange SSAR shirt. I couldn't wait to get home and try it on. It turns out that a medium looks like someone shrink-wrapped the material onto my upper body. Not pleasant ... especially when I looked in the mirror. No emergency here ... I simply texted Rebecca and she solved the problem. Lets just say that Sean will be at the next event in a material way.
One of the workshops I attended had a device that could locate a person with the help of a small transmitter worn by an individual. It was a little bigger than a watch. We simulated a search by sending out a member with a 10 minute head start outside the building. Using a hand held Yagi antenna which looked like a radar gun, we proceeded to determine a bearing by listening to the strength of successive tones. The unit works very well. The Winnipeg SAR member that did the demonstration indicated that they have successfully used the system in many places. This might be something to consider as our organization evolves. I think funding may be a challenge for many of these pieces of valuable technology.
The hypothermia demonstration was very interesting. The presenter from Ontario was working with information provided by a hypothermia researcher from Manitoba. One of the many takeaways was to protect the insulated materials that are layered onto the subject with plastic to ensure they don't get soaked. These items lose their heat containing properties when wet! We also identified the phases a person will go through when in a cold water scenario. So many details were shared and hopefully will stay retained.
An RF engineer did the presentation on radios. A very thorough run through of radio technology. The presenter mentioned that he is a member of Casara (Civil Air Search and Rescue). Interesting ... I will have to find some time to do some reading and look them up. About the only thing I know about them is that they fly around in airplanes and search from above. I am sure there are many more details I will learn over the next year.
Adventure Smart ... hmmmm ... whats that? I attended a session describing this very important program. The idea behind it is to attempt to give kids the tools to survive being lost in an unfamiliar environment. The most important ingredient hammers home the message of prevention. (How to not get lost in the first place!) A brilliant dramatic re-creation was shown to demonstrate how kids can be empowered to be a part of their own rescue. I would like to find a link to this video and post it!
The clue awareness session was very entertaining yet educational at the same time. We were shown a video of people passing around a basketball and were asked to count how many times this had been done. I became hyper focused on following the ball. Unfortunately this completely eliminated my peripheral vision. Ugh! We were all asked if we saw the giant gorilla. Yes ... it turns out that in the middle of this short video a large man in a gorilla suit walked slowly through the middle of the frame. Lesson learned! You can look for something specific, but don't let that bias impede your ability to locate other clues. Keep your periphery intact!! I will try to locate the YouTube link and post it. We also watched a Who Dunnit video. This one made me laugh ... it was informative! Again ... I will try to locate these links and post them for reference.
Unfortunately, I didn't get to see the lecture from Environment Canada. I stood in the hall for a while after one of my other sessions for about the last 15 minutes. It looked very well presented. I am going to ask around for a name and see if I can find out who the presenter was. It looked fantastic and will be advantageous to gain this knowledge.
I attended ICS training and we got a little more than we asked for. We covered all of the material and then some! We had a practical conversation about how ICS plays out in the real world. The speaker was open to discuss the challenge of getting many different organizations to work together. A firefighter was present at this session who helped fight the northern fires last summer. A discussion ensued that debated the finer points of ICS. I am taking ICS 100 and 200 soon and I felt this session has given me a solid foundation.
One of the strange things I admire about the SAR group is their unusual predictability. Its Saturday night, we just had an amazing meal, everyone has a full stomach and is a bit sleepy. Shall we go home and fall asleep in front of our favorite TV show? Nope ... how about a hike in the pitch black wilderness to attempt to understand the better aspects of using a FLIR during a night mission. My kind of people!
On a solemn note, there was a point after supper that they played a video of Search and Rescue volunteer professionals that have lost their lives while training or on a mission. It was a very emotional video.
I know that I have only shared a small part of a jam packed weekend. It was a pleasure to spend it with so many outstanding people from across the country.
