3.4 Preparations on site
The cleaning date should be co-ordinated with the maintenance personnel (possibly process
electrician) in charge of the escalator.
The safety manager should also be informed if necessary.
Have the escalator switched off by the relevant specialists and secured
against being switched on by accident!
Remove escalator key!
The operator must plug in the mains cable for the machine, or a suitable socket must be
shown to him.
The operator must furthermore obtain instruction on manual control of the escalator or else
ensure that some person familiar with the workings of the escalator is available near by at all
times.
3.5 Safety measures on site
All unauthorised persons must be prevented from approaching the entrances at both ends of
the escalator by means of safety measures (e.g. red-and-white barrier chains).
