Q

Standards carry what fraction of the duty live load, per platform, per bay?

Study These Flashcards
A

25% = One fourth.

24
Q

What must be done to all access on any incomplete scaffold you intend to leave overnight or unattended? List two (2) risk controls.

Study These Flashcards
A
  1. Access should be removed, isolated or barricaded off
  2. Scaffold incomplete sign
25
On completion of a hung scaffold that has been inspected and deemed safe to use, what documentation is required?
Handover certificate.
26
What are five (5) pieces of information you would find on a hung scaffold data plate?
Any five of the following: • Type • Model • Working load limit (WLL) • Serial number • Manufacturer's name • Manufacturer's identification • Detail of the FSWR required • Reeving requirements • Power supply requirements
27
To avoid overloading the hoist rope needles and suspension rig on a suspended scaffold, what device can be used?
A load limiting device
28
Why is it critical to use a wire rope specified by the manufacturer for a scaffolding hoist?
It can fail completely and the platform could fall. ## Footnote The wire rope can be seriously damaged. The sheaves may destroy and/or damage/break the rope.
29
What is the minimum working load limit for trolleys supporting a scaffold?
500kg
30
Where is the best place to attach the cradle's working load limit?
On the inside
31
What is a swing stage cradle's minimum width at any given point?
450mm
32
What are the dimensions of a work cage?
Minimum width: not less than 700mm Maximum width: not more than 1500mm
33
What type of material should be used as counterweights for a needle?
Durable material where the weight remains constant under working conditions. ## Footnote As approved by the manufacturer.
34
What information do counterweights permanently display?
The mass of the counterweight in kilograms
35
How should counterweights be attached to a needle?
In such a manner that they cannot be displaced or removed without the use of the tool.
36
What are two considerations when selecting a fall arrest harness?
Anchorage point strength Maximum fall distance Sharp edges
37
When using a shackle on a suspension rope, what maximum rope tension is permitted?
80% of the working load limit
38
When using a choked sling on a suspension rope, what maximum rope tension is permitted?
40% of working load limit
39
What measures can be taken to stop a shackle pin from unwinding accidentally?
The pins should be moused or lashed ## Footnote Use a locking device
40
Explain why you would use spacer ties and spreader bars on suspended scaffold needles or trolleys.
To prevent movement ## Footnote To prevent the rope from disconnecting and the cradle falling
41
At least three full turns of rope should remain on the hoist drum at all times. List two (2) reasons why this is necessary?
To reduce tension on the anchorage point on the drum ## Footnote Prevent damage at the anchor point
42
Why is it necessary for the drum flange to extend two (2) rope diameters past the built-up rope?
To prevent the rope jumping over the drum flange.
43
What is the minimum length of remaining rope that must be available when a climbing type scaffold is at its lowest position?
One (1) metre
44
When altering or erecting suspended scaffolds and suspension rigs what documentation should be consulted?
Design specs
45
How would you prevent damage to a scaffolding hoist mechanism when loading or unloading materials to and from the platform?
By using a purpose-made cover.
46
Why would you attach a tie from the hoist-tower to an adjoining structure?
To maintain the tower in a fixed position.
47
What must be set up if there is a possibility that debris may fall from above the cradle?
Suitable overhead protection.
48
Who would be responsible for evaluating the intended loadings on a supporting structure for a suspended scaffold?
A competent person such as an engineer.
49
Write the horizontal clearances that are required between the moving platform of cantilevered hoist and any landing or floor.
Minimum: 25mm ## Footnote Maximum: 150mm
50
What needs to be provided when there is a clearance of more than 100mm between the hoist platform and the landing platform?
A fold down flap or bridging gap.
51
A landing gate for a cantilevered hoist must be a minimum height of?
1.8 metres.
52
When installing a cantilevered hoist what is the maximum distance allowed between the ties/braces?
As per Manufacturer's specifications.
53
Why are there landing gates installed for a cantilevered hoist?
To prevent people, tools and equipment entering the path of the hoist.
54
What is the only grade of ladder that can be used when accessing a hung scaffold platform
A single industrial ladder
55
When extending a portable access ladder above a landing minimum height it should be extended?
900mm
56
What are 2 things you need to consider when installing access ladders on hung scaffolding.
1. Angle of the ladder 2. Extension above the ladder
