Does scaffolding need to be attached to the building?
In general,
most scaffolds need to be tied to an existing permanent structure
. There are exceptions where there is a necessity for a scaffold to be designed without any ties. … Most scaffolds, however, require some form of tying arrangement, whether that's a wall, a column or exposed steelwork.
Do scaffolds have to be tagged?
There are currently no specific requirements that warning tags must be placed on all scaffolds
while they are being erected. … GREEN Green “OK” tags should be hung on scaffolds that have been inspected and are safe to use. A green “OK” tag is to be attached to scaffold at each access point after the initial inspection.
How often does scaffolding need to be inspected?
A scaffold used for construction should be inspected
before it is used for the first time and then every 7 days
