Prussik Cord

www.vententersearch.com

Aaron Drake from Greenville (NC) Fire sent in a picture of something they have added to the tip of the aerial to help with ladder placement. A simple set of prussik cords were placed on the aerial by Jacob Valevich. The cords have a large knot tied in the end to give the end of the cord some weight. A monkey’s fist knot would work well in this application, and provide for a more finished look. The idea is that when you see the cords hit the wall, you can verify that the ladder is extended over the roof. Then, lowering the ladder until the cords just hit the roof ensures the proper clearance, allowing for ladder bounce and still providing an easy step onto the roof. While this idea may not be needed for a full time aerial operator, it may be good for relief drivers or someone simply training on aerial placement.

Valuable Time

Flip Fierro from City of Raleigh (NC) Ladder 1 sent in a door he found that proves a very valuable forcible entry lesson. Forcing the door may be much simpler than you think. At first glance this door appears that it has two drop bars installed, as indicated by the carriage bolt heads. But as you can see from the photo below, the supplemental drop bar has been removed.

If you look close the photo below you can even see that the door has a significant bow in it where the drop bars used to be in place. This should be a good clue that the door needs to be further evaluated prior to selecting a forcible entry technique. Simply “gapping” the door with the irons (near the suspected supplemental lock) would verify whether or not the bars are installed. It would only take a second. Valuable time could certainly be lost trying to defeat a supplemental lock that in not in service.
