Just as a small note there Guys,
If you are erecting a tall extension ladder, just make sure that the first person that climbs the thing ties it off to something, whatever it is!.
This may seem like a given statement, but there was a Fire Brigade in the North Island of NZ that "lost" a 30metre ladder and a FF when he turned the branch of the High Pressure Hose Reel that he was holding to one side and it was a situation of what goes up, must come down.
The Hose Reel was running at 3MPa, this would have been a very quick accident. [Linked Image]
