Basic Rigging (BOOM VOC)
At what frequency must static line / safety harness anchorage be inspected by a competent
person? - ANS-Before and after every use
\Can flexible steel rope be safely used on a fibre rope tackle box? - ANS-No, the two are
incompatible.
\Do you expect that a Permit would be required for lifting personnel in a Workbox? - ANS-Yes,
every time a workbox is used
\Give 6 examples of what types of hazards you would look for when planning a lift? -
ANS-Ground conditions, other work crews, wind, lightning, underground services, surrounding
structures, power lines
\How can our pre-lift planning help us protect others from our activities? - ANS-Identify
interfaces, access points and other work crews in the area
\How much wear is allowed on chains & sling is allowed for them to remain in service? -
ANS-10%
\How should we warn personnel in the area that a load is being moved? - ANS-By signals
(hand, Horn, Radio, Call, etc)
\How should you control a load in a pick and carry situation? - ANS-Tie the load back to the
crane
\How would you identify hazards in the workplace during the pre planning for a lift? - ANS-By
using the pre-lift assessment and pre-lift discussions with the crew
\If a 10mm T-Grade chain has a WLL of 3.2 tonnes in a straight tension, what could two of these
slings lift when set at 90 degrees & attached by shackle to the load ? - ANS-4.5T
\If a sling has been repaired can it be put back into service? - ANS-No must be approved and
tested prior to use
\If you are presented with a bolt, nut and washer for steel erection, how would you determine
that they were the appropriate grade for use? - ANS-The bolt will have 8.8 & 3 radial marks,
nuts can be identified by 3 arcs embossed or indented on the non bearing faces and washers
will be either flat round with protruding ribs or square tapered with either a 5 or 8 degrees.
\If you are standing on a scaffold with a suspended load above the scaffold what do you do? -
ANS-Either move the load away or move myself
\If you had to escort the crane on foot where would you walk? - ANS-Forward of and to the side
of the crane out of its path and in full view of the crane operator
\In slinging a load, what action would you take to ensure the load was secure before hoisting the
load to the top of the structure? - ANS-Do a test lift
\On a mine site how close to live electrical conductors are you allowed to work? - ANS-Within 10
meters
\State the allowance that is required when two slings are set at an included angle of 90 degrees
and attached directly to a square load? - ANS-20%
\Weight of cubic metre of concrete? - ANS-2400kg
\Weight of cubic metre of steel? - ANS-7800kg
\Weight of cubic metre of water? - ANS-1000kg
