If you are working with and on ladders please take the time to do this properly and follow the safety guidelines from the manufacturer or your work safety authority.
There is a lot of information available on the internet such as this useful guide
“10 Steps to ladder safety“ or “Ladders – Safework NSW“
Remember
Make sure your ladder is stable and set up properly, don’t overstretch – take the time to move the ladder and most of all work safely.
