The only persons allowed to lift floor tiles in the computer
halls are the technical staff and any other staff specifically
authorised by the Head of Division or his Safety Representative.
These people will be aware of the risks of injury and also the
position of fire alarm sensors. Any area of floor with the tiles
removed must be guarded by a suitable barrier.
These areas must be kept tidy in order to prevent
any loose cables from equipment presenting a tripping hazard.
The Central Services area in the South Computer Hall is a Restricted Area.
No-one other than computing staff directly involved with the operation of
equipment in this area is allowed entry.
Power to the various areas and workshops within
the Computer Halls is supplied and
controlled by the wall mounted Power Distribution Units. (PDU's.)
ONLY technical staff and specific authorised staff are permitted to operate
the Power ON switch on any of these units. The Emergency Stop button may be
operated by anyone in an emergency situation.
