Think about it logically
You have to state the obvious , manager.... site supervisor........
author,,,,,,,,,, your position .... date
outline the hs objectives
what the activity entails
the locationany restrictions
access
environment
how you are going to safeguard the public etc
emergancy measures
how many operatives/ what training
ppe
equipment
materials and handling info
Then write down every type of movement you make
1 arrive at building and report to site manager.
2 recieve site induction
3 place out safety cones and barrier tape
switch on water delivery system
5 roll out hose and switch on electrical supply to pump all etc
Skip a few it should become obvious by now what more you need
13 lift pole to a comfy position......blah blah
15 wash window using an up and down motion using your body etc
16 clean all windows on that level etc
28 pack away blah blah
See what i mean you really have to spell it out
