Although personal fall arrest systems pfas are the most widely used form of fall protection in residential construction they might not be suitable when workers begin installing roof truss sections because there may not be a stable place to attach an anchor.
Safety plan roof trusses.
Depending on the building layout and the tasks involved lifts e g aerial scissor may be options for setting.
Placing trusses onto housing frames using powered mobile plant such as a vehicle loading crane may also be required.
Exterior bracket scaffolds can also be used for installing roof trusses and other rooftop construction activities.
Roof trusses are the highest part of a house frame so residential construction workers.
The guardrail system on the scaffold can provide fall protection.
The erection of roof trusses may place employees at risk of falling from a height that is greater than 2m.
By assembling a truss section on the ground employers can greatly reduce the risk of falls for workers.
Tying off to trusses in the early stages of construction can easily cause a greater hazard given that a fall may pull the truss or trusses down with the fall.
1 truss construction usually occurs high above the ground and 2 trusses are not stable until they are properly restrained and braced.
Trusses are very unstable prior to being properly braced or sheathed.
This is particularly true if the worker is depending on the tie off to the trusses to protect him her from a fall.
When properly constructed and used.
