At what height does a scaffold need guard rails?
If an employee is working on a scaffold, the height requirement for fall protection is 10 feet, and this protection usually is provided by a guardrail. The OSHA standard requires employers to protect each employee on a scaffold more than 10 feet (3.1 m) above a lower level from falling to that lower level.
How high can you build a rolling scaffold?
Scaffold tower can be erected in all shapes and sizes. The standard dimensions are 5 foot and 7 foot long. Reaching 5 foot high all the way up to 30 feet tall.
At what height does a scaffold need to be engineered?
Construction scaffolding safety is paramount. OSHA further states that scaffolds more than 125 feet in height above the base must be designed by a professional registered engineer.
What is the maximum height of a mobile tower?
around 10-12m
A mobile access tower (or ‘zip up’ tower) provides a free standing, stable working platform up to a maximum height of around 10-12m.
Does mobile scaffolding need to be tagged?
Must I use a tag system on a scaffold? Although tag systems are not a legal requirement, the law does require inspection of scaffolding from which a person might fall 2 metres or more and the issue of a report by a competent person, on completion and at least weekly thereafter.
When dismantling a scaffold All work should be conducted?
When dismantling a scaffold, all work should be conducted: From the top down. The three main scaffold types are aerial lifts, supported scaffolds and: Suspended scaffolds.
Can a person ride on a rolling scaffold?

What is the 3 to 1 rule in scaffolding?
The 3 to 1 rule. The total working height of a freestanding scaffolding tower should be three (3) times the distance of the narrowest side of the base (if this is a measurement of outriggers, they must be set symmetrically about the tower). Always check for overhead power lines before moving any scaffolds.
Do I need a scaffolding Licence?
If your builder or scaffolder needs to put up scaffolding within the boundary of your property there is no need for a licence. However, if any part of the scaffolding needs to go on the pavement or the road outside your property your builder or scaffolder must get a licence from your local council.

Does a scaffold have to be tagged?
Presently, there is no requirement that warning tags be placed on all scaffolds while they are being erected. Although there are instances where such tags are appropriate and a citation under 29 CFR 1926.200(h)(1) could be issued, there are also many instances where such would not be appropriate.
Is there a rule of thumb for outrigger support?
No rules of thumb, no wing and a prayer, no best guess, just a calculation to determine the size of cribbing/blocking required. A key thing to remember is that as a crane works and rotates over the various corners and quadrants, the load will shift and at any one time a greater load will be placed on one outrigger than on the others.
When do outriggers and stabilizers need to be used?
When the load to be handled and the operating radius require the use of outriggers or stabilizers, or at any time when outriggers or stabilizers are used, all of the following requirements must be met (except as otherwise indicated):
When to use outriggers on a crane truck?

How tall do you have to be to put outriggers on a scaffold?
This would mean that if you are on a 5′ wide scaffold tower and your platform height is 20′ or higher, you would then have to install outriggers on the scaffold or secure the scaffold to the structure to prevent the scaffold from possibly tipping.
