Having found the perfect spot to hang your...

picture, you begin to fix it to the wall
Never drill holes or fix nails in walls or
partitions without knowing what is hidden
behind them. Walls and partitions hide
electrical cables and gas and water pipes.
Drilling through a live cable is extremely dangerous, and could cause
electric shocks, burns or even fire. A cable-and-metal detector will
help find any cables and metal pipes.
In modern electrical installations, cables are normally run in a straight
line, either horizontally or vertically, to an accessory such as a switch
or socket. Cables may also run within I5 centimetres (cm) from the
top of the wall or partition or within I5 cm of an angle formed by two
walls or partitions.
