Answer: It warns the operator of overload conditions.

15. What PPE is required for boom truck operators?

Answer:

• Hard hat
• High-visibility vest
• Safety boots and gloves

16. How should an operator respond to mechanical failure?

Answer:

• Stop operations immediately
• Secure the boom and load
• Report the issue for repair

17. What are the common causes of boom truck tip-over?

Answer:

• Exceeding load limits
• Uneven ground positioning
• High wind conditions

18. How should loads be lifted safely?

Answer:

• Lift straight up, avoiding sudden movements
• Keep load within the truck’s center of gravity

19. What is the best way to transport a boom truck safely?

Answer:

• Retract and secure the boom
• Follow road weight limits
• Ensure proper signage if over-dimensional

20. How often should a boom truck be inspected?

Answer: Before each shift and regularly as per manufacturer and OSHA guidelines.

21. What are the risks of operating a boom truck in poor visibility?

Answer:

• Increased risk of collisions
• Difficulty in judging distances

22. How should a boom truck be shut down after use?

Answer:

• Lower and secure the boom
• Turn off the engine
• Engage the parking brake

23. What is the function of a boom angle indicator?

Answer: It shows the angle of the boom to ensure safe lifting operations.

24. What are the best practices for refueling a boom truck?

Answer:

• Turn off the engine
• Avoid open flames
• Use the correct fuel type

25. Why is a spotter important in boom truck operations?

Answer:

• Assists with blind spots
• Helps prevent collisions

26. How can an operator avoid fatigue?

Answer:

• Take regular breaks
• Stay hydrated

27. What is a jib on a boom truck?

Answer: A jib extends the reach of the boom for higher lifts.

28. How should a boom truck be parked on an incline?

Answer:

• Use wheel chocks
• Engage the parking brake

29. What should be done if a load becomes unstable?

Answer:

• Lower it safely
• Re-secure rigging

30. What is the importance of load charts?

Answer: Load charts help operators determine safe lifting capacities.

31. What is a swing radius hazard?

Answer: The area around a rotating boom where people can be struck.

32. What are the risks of lifting loads over workers?

Answer: Falling load hazards can cause serious injuries or fatalities.

33. How do you ensure communication between the operator and ground crew?

Answer: Use radios, hand signals, or spotters.

34. What should you do if a hydraulic line bursts?

Answer:

• Stop operations
• Isolate the system

35. What are the key functions of boom truck controls?

Answer:

• Boom extension/retraction
• Lifting/lowering the load
• Rotating the boom

36. Why is it important to avoid sudden movements?

Answer: It can destabilize the truck and cause load swings.

37. What is the purpose of a counterweight?

Answer: It balances the load to prevent tip-over.

38. What is a boom truck’s rated capacity?

Answer: The maximum weight it can safely lift.

39. How should the truck be prepared for transport?

Answer:

• Secure the boom
• Check tire pressure

40. What is outrigger cribbing?

Answer: Wooden or metal pads placed under outriggers to improve stability.

41. Why is weather monitoring important for boom truck operations?

Answer:

• Wind affects stability
• Rain can make surfaces slippery

42. What is a work zone hazard assessment?

Answer: A checklist to identify and mitigate risks before lifting operations.

43. Why should the boom not be fully extended at high loads?

Answer: It increases tipping risks due to leverage forces.

44. What is the importance of a backup alarm?

Answer: It alerts nearby workers when the boom truck is reversing.
