However, where the employer can demonstrate that it is not possible to place an outrigger beam perpendicular to the face of the building or structure because of obstructions that cannot be moved, the outrigger beam may be placed at some other angle, provided opposing angle tiebacks are used. This provision does not preclude the use of systems which are designed to function both as suspension scaffolds and emergency systems.

Each platform must be planked and decked as fully as possible with the space between the platform and uprights not more than 1 inch (2.5 cm) wide. When Scaffolding is Needed The very short answer is: when a risk assessment outlines it is necessary! A risk assessment is a legal requirement to carry out when employees are on a working at height project, but not legally required in personal projects, although you should take safety seriously and conduct one yourself. Each suspension rope, including connecting hardware, used on adjustable suspension scaffolds shall be capable of supporting, without failure, at least 6 times the maximum intended load applied or transmitted to that rope with the scaffold operating at either the rated load of the hoist, or 2 (minimum) times the stall load of the hoist, whichever is greater.
