I'm a firefighter on a small naval installation. To the best of my knowledge we only have about 3 buildings on the entire installation with elevators, and the highest only go as high as 6 stories high. We don't get alot of elevator calls but when we do were excited to managed the situation like the professional we are with only limited about of training. This is a good learning tool for me and I will used it as visual aid to share with the rest of guys. Thanks alot for the education.
