Hi
My enquiry is with regard to lighting in a confined space.
Can you have 110 volt cable trailing through the access/egress entry point, if a risk assessment shows that the risks of cutting or damaging the cable is minimal or does the lighting have to be 25volt?

Steve,
you put anything you like in a confined space as long as the risk assessment shows that you have reduced the risk to acceptable levels.
Putting 110v lighting cable in through a side access is ok providing you prevent damage and that the lighting is either ex rated or you have mitigated the risk of explosion in another way. You might want to consider armoured 110v cable if you feel the risk of damage remains.
It would be worth checking with the client as some of them have quirky rules about managing confined spaces and no matter what systems you put in place they insist on certain equipment.
You will of course control this on your permit to work?

The issue is generally one of bulb breakage as most cables can be protected. Ideally you should look at the 110v fluorescents that are available, they are also available with an emergency lighting pack so that there is still light when the power goes off- a common occurrence on sites!!! I personally detest bulbs on Fairy, sorry festoon, lights as they get broken and can expose live conductors. 110volt is not safe it is safer. Some time ago a welder was killed in such a situation when a bulb was broken and the conductors touched the tank side. In the right circumstances it can kill so I would go 25volt or lower if you must have bulbs.
