WITH ACCURATE SOLUTIONS 2026
▶ Truck-mounted and rough terrain cranes are both forms of a mobile
crane, and both use which of the following to increase their stability?
Answer: outriggers
▶ Rated load capacities, recommended operating speeds, and special
hazard warnings or instructions must be: Answer: Conspicuously posted
on the crane, where the crane operator can see them while he is at his
control station
▶ The four lifting principles that govern a crane's mobility and safety during
lifting operations are: Answer: Center of gravity, leverage, stability and
structural integrity
▶ Employees working in the vicinity of a crane must take care to avoid
what kind of accident? Answer: "Struck by"
▶ Personnel hoisting platforms must be designed by: Answer: A qualified
engineer, or another competent specialist qualified in structural design
▶ True or False: Only personnel instructed in the requirements of the
standard and the task to be performed - along with their tools, equipment
and materials needed for the job - are allowed on the platform. Answer:
True
▶ If the hoist tower is not enclosed, the hoist platform or car must be totally
enclosed on all sides for the full height between the floor and: Answer: The
overhead protective covering
▶ The greatest hazards posed by hand tools result from: Answer: misuse
and improper maintenance
, ▶ Power tools should never be carried by the cord or hose or be yanked
from a receptacle by the cord or hose; and cords and hoses should be kept
away from: Answer: Heat, oil, sharp edges
▶ Sharp, abrasive, pinching, or otherwise hazardous moving parts of
power tools: Answer: Must have protective guard to prevent contact with
workers
▶ Before an abrasive wheel is mounted, it should be inspected closely and:
Answer: Sound- or ring-tested to ensure that it is free from cracks or
defects
▶ Neither the operator nor anyone else should ever stand directly in front
of the wheel of an abrasive power tool as it accelerates to full operating
speed. Why? Answer: Because there is always the chance that the wheel
wasn't sound and could disintegrate or explode
▶ Pneumatic tools are powered by: Answer: Compressed air
▶ Powder-actuated tools are extremely dangerous, with a "firing"
mechanism similar to that of: Answer: A loaded gun
▶ If a powder-actuated tool misfires, the employee should: Answer: Wait
at least 30 seconds, then try firing again
▶ All jacks - lever and ratchet jacks, screw jacks, and hydraulic jacks -
must have a device that stops them from: Answer: Jacking up too high (a
stop indicator)
▶ OSHA defines a trench as: Answer: A narrow excavation made below
the surface of the ground in which the depth is greater than the width - with
the width not to exceed 15 feet
▶ True or False: There is usually some form of warning before a cave-in.
Answer: False
▶ OSHA requires that all excavations in which employees could potentially
be exposed to cave-ins be protected by one or more of the following three
methods: Answer: Sloping, benching, shoring, shielding
