I couldn't see this posted anywhere else but apologoes if it has. I've just been forwarded this
HSE - Services - Education ? Information sources / Guidance - Laptop computer charging trolleys safety alert
I've only skimmed it but it looks like interesting reading.
Have just checked and our Lapsafe trolleys are manufactured to CE mark standards.
Plus staff remove the cable from the Trolley rather than the socket so reducing the risk.
How does that work?Plus staff remove the cable from the Trolley rather than the socket so reducing the risk.
Our lapsafe trolleys use a standard kettle lead same as a desktop PC. So staff just remove this rather than direct from the wall.
It's only used by our techs but we remove the lead direct from the trolley. We do tend to turn the power switch to off before pulling it out mind!
Interesting read though, cheers
In the advice it says we should use "blue coloured euro-connectors to BS EN 60309" anyone got a picture or link to what these are?
My guess would be these.
Well they are going to make it really portable to take around school!, Do I now have to have to change the wall sockets everywhere I need the trolley to be? If I do arn't I hoing to be Mr Popular!
How will a different plug archive anything?
What is the risk?
A HSE investigation into an electric shock incident involving a laptop charging trolley found that when a 3-pin plug supplying the trolley was removed from the supply socket there was sufficient stored electric charge on the pins of the plug to give the user an electric shock.Think that explains it.i.3-pin plugs should be replaced with blue coloured euro-connectors to BS EN 60309 (This ensures that the plug pins remain out of immediate contact on insertion and removal)
I've pulled plugs out in such a way that my finger/s end up hitting the tips and i've also done this on Microphone based plugs which are very similar if not the same expect for the number of pins.....
Changing to CEE form plugs isn't going to be simple, and will only provide a small increase in safety. As they are unfused, you would need either a local fused spur to feed it, or a spur wired back to the local breaker board.
I will concede that you are slightly less likely to touch the pins of the plug, but:-
The flaps bite hard.
You can easily open the flap and stick things into the live socket.
It is still easy to touch the pins.
If you really need to change, I would suggest you look at the Powercon system from Neutrik. Fully sleeved in all configurations.
This isn't something that your run-of-the-mill sparky will have come across! Would still need fusing in some way.
Hi, if you read the document thoroughly, it states that you only need the 'comando' type adaptors if you don't have a CE marked trolley.
We have a LapSafe(R) so luckily no worries, just checked their website and they have a thing on the HSE alert on there.
