Staple gun sales will rise......

 the main one that affects you lot is that all cables in all environments that are mounted in a escape routes now have to have metal fixings, 

 

So what type of metal fixing are we all using for one eight core cable?

Staples are fine. The reg only requires metal supports/fixings for  "premature" failure.

Sorry for links it takes to long to link pictures

Here are some examples for when you use plastic trunking, you may have see or used the second type before for your fire alarm cable drops.

what is the time it has to last?

 

also what if fixing to wood, does it define that?

Wiring systems in escape routes – The following amendment is in response to the deaths of firefighters attempting to rescue people who have become entangled in collapsed wiring systems:

• Wiring systems in escape routes shall be supported such that they will not be liable to premature collapse in the event of a fire.

This means that wiring systems will have to be supported by metal fixings and cable ties or held in metal containment. Alternatively, conductors may be retained inside non-metallic containment with metal clips or cleats

Time is just premature as there would be no way of stating a time with all differing building materials and fixings.

Fixing to wood is fine because by the time the wood is alight and in danger of failure you would be past the premature stage and hopefully not using it as an escape route anymore.

The brigade might be though. I'd say if an escape route was useable then plastic support would still be intact.
