1. What is the minimum safe distance to keep from overhead power
lines when operating heavy equipment?
10 feet
This distance is specified by OSHA to prevent accidental contact and
electrocution hazards.
2. What is the primary purpose of a pre-operation inspection?
Identify and correct safety or mechanical issues before use
A pre-check ensures the equipment is safe and functional, preventing
breakdowns or accidents.
,3. When lifting a load with a crane, where should the operator position
the boom for maximum stability?
Directly over the load
Keeping the boom centered reduces side loading and risk of tipping.
4. What does the term "rated capacity" mean in heavy equipment
operation?
The maximum load the machine can safely lift under specific
conditions
Rated capacity is determined by the manufacturer and ensures
structural and operational safety.
5. What is the first step before starting any earthmoving operation?
Survey and mark the work area
Marking identifies hazards, underground utilities, and boundaries
before digging begins.
6. When operating a backhoe, what should be done before traveling with
the bucket raised?
Lower the bucket close to the ground
This lowers the center of gravity and improves stability while
moving.
7. Why is counterweight important on cranes?
It balances the load and prevents tipping
Counterweights offset the lifting force, ensuring the crane remains
stable.
,8. What is the main danger of overloading an excavator bucket?
Instability and potential tipping
Exceeding bucket capacity shifts the center of gravity dangerously.
9. What type of fire extinguisher should be kept on heavy equipment?
Class ABC extinguisher
It covers combustible solids, liquids, and electrical fires common on
machines.
10. What is the correct procedure when approaching a blind corner
with heavy machinery?
Sound the horn and proceed slowly
Warning others reduces collision risk in areas with obstructed
visibility.
11. What is the correct tire inflation pressure important for?
Machine stability and load handling
Improper tire pressure can cause uneven weight distribution and
unsafe handling.
12. When working near a trench, how far back should heavy
equipment remain from the edge?
At least the depth of the trench
This prevents soil collapse from equipment weight.
, 13. Why is it dangerous to swing a crane load over workers?
Risk of injury or death from falling objects
Loads can shift or fall unexpectedly, creating a lethal hazard.
14. What is “creep speed” in heavy equipment?
A slow, controlled movement for precise work
Creep speed allows better control when positioning or aligning loads.
15. How often should heavy equipment be refueled?
At the end of each shift
Refueling after use prevents condensation in the tank and ensures
readiness.
16. What is the main advantage of using a spotter?
Improved safety through better visibility
Spotters can see blind spots and guide operators around hazards.
17. What is the proper action if hydraulic hoses are leaking?
Stop operation and repair before use
Leaking hoses can cause loss of control and are a fire hazard.
18. What should be done before lifting a suspended load?
Check load balance and secure rigging
Improper rigging can cause swinging or falling loads.
19. What is the main hazard when traveling with a load uphill?
Tipping backward
The load shifts weight to the rear, reducing stability.
