air breaker operator Interview Questions and Answers

1. What is an air breaker and how does it work?

   • Answer: An air breaker is a pneumatic tool used to break up hard surfaces like concrete, asphalt, or rock. It works by using compressed air to power a piston that drives a chisel or point, creating powerful impacts that fracture the material. The compressed air is channeled through a hose from a compressor to the air breaker.

2. Describe the safety precautions you would take before operating an air breaker.

   • Answer: Before operating an air breaker, I would inspect the tool for damage, ensure the air hose is in good condition and properly connected, wear appropriate safety gear including hearing protection, safety glasses, steel-toed boots, and a hard hat. I would also clear the work area of any obstructions and ensure there are no bystanders nearby.

3. How do you maintain an air breaker?

   • Answer: Regular maintenance includes lubricating moving parts as per the manufacturer's instructions, regularly checking for leaks and damage, cleaning the tool after each use to remove debris, and storing it properly in a dry place.

4. What are the different types of air breaker chisels and what are they used for?

   • Answer: Different chisels include flat chisels for general demolition, pointed chisels for breaking up concrete, and spade chisels for narrow trenches. The choice depends on the material being broken and the desired result.

5. How do you adjust the air pressure on an air breaker?

   • Answer: The air pressure is typically adjusted at the compressor itself, not directly on the air breaker. However, some air breakers have a regulator on the tool itself to fine-tune the impact force.

6. What are the signs of an air breaker malfunctioning?

   • Answer: Signs include reduced impact power, unusual noises (e.g., grinding), excessive vibration, leaks from the tool or hose, and the tool becoming unusually hot.

7. What should you do if an air breaker malfunctions?

   • Answer: Immediately turn off the air supply, disconnect the air hose, and inspect the tool for damage. If the problem cannot be easily identified and fixed, take it out of service and report it to your supervisor.

8. Explain the importance of wearing hearing protection when operating an air breaker.

   • Answer: Air breakers produce extremely loud noise that can cause permanent hearing damage. Hearing protection, such as earplugs or earmuffs, is crucial to prevent hearing loss.

9. What are the potential hazards associated with operating an air breaker?

   • Answer: Hazards include hearing loss, hand-arm vibration syndrome, eye injuries from flying debris, and injuries from the recoil of the tool.

10. How do you handle flying debris when using an air breaker?

    • Answer: Wear appropriate eye protection and potentially a face shield. Use a barrier to shield bystanders. Work carefully and control the direction of the impacts.
