fall arrest system questions
Hello, I came across a permanently installed fall arrest system. I want to be able to use it. It's a vertical ladder with a rail in the middle, no cage around it. I looked around and found this: http://www.cresto.dk/en/produkter/fasta_inst_sss.html
The ladder shown on that page looks like the ladder I saw, though I didn't take any pictures of it so I'm not sure it's the same. Obviously there's a European standard (BS EN 353-1:2002), so it's probable.
Questions:
1. In Scandinavia, are there any other similar standards in use, with different dimensions perhaps? If I buy an EN 353-1 sliding lock, will it fit the rail I found?
2. Is it possible to detach the lock from the rail at any time? If not, is it generally possible to detach it at the top?
3: Anything I should know about it when using it with a sit harness? I'm not a climber.
Help appreciated,
