I've had old screw gates vibrate open when attached to the saw, just use 3'way know

[Gary Prentice]

Old though is the operative word. Wear and tear through usage causes or caused loose gates, which would be relegated to 'not for climbing' uses or binning. As part of the inspection regime they were safe or should have been.

 

Instead it was decided the three ways were safer despite the brand new, previously unused and factory fresh krabs opening in certain configurations.

 

I'd be interested if anyone could shed any light on why the industry thought three ways were a step forward and what was wrong with the screwgates. Personally I suspect that operator error was the greatest cause of accidents (failure to lock the gates)

It was the HSE that decided. They said that 3wl should be used for main line attachment particularly where repeated opening was going on.

I assume that was under guidence/consultation with the industry? It still seems strange to change to something that they acknowledge isn't really safe either. I'd be interested to find out a bit more as to the reasoning behind it. Was there an unacceptable number of accidents due to them, has that number declined, does the rope access industry use the same now and so on.

 

It intrigues me what was behind it, that's all.

The HSE listens to industry but evrything they do comes back to their mandate to protect people.

 

The two and then three action gates were seen as an improvement over screw gates for personell main line attachement. From memeory one of the main issues cited was repeated opening and closing could lead to a gate not bieng properly secured. The self locking action of the three way gate was seen as a better option.

 

Clearly three action gates are becoming ubiquitous but initially they were the HSE's "preferred" option for main line attachment and there is no real compunction to use them elsewhere if you have viable alternative

Thanks Andy, that's also pretty much the answer I got at college today.

Nice to see that the institutes of learning know what they are talking about.

I still use a few screwgates for rigging.

It's nice to know its impossible for them to come undone in a single operation.

 

The biggest problem we've had is getting the buggers undone sometimes!
