CPO CPO Emergency Procedures & Incident Response 1 — Questions and Answers
Question 1: What is the first action an operator should take if a concrete pump boom contacts an overhead power line?
- Climb down immediately to call for help
- Stay in the cab and call 911, warning others to stay away from the machine (Correct answer)
- Use a wooden stick to push the boom away from the line
- Continue pumping while slowly lowering the boom
Correct answer: Stay in the cab and call 911, warning others to stay away from the machine
If the boom contacts a power line, remain in the cab (do not become a path to ground), call emergency services, and warn bystanders to stay clear.
Question 2: When should a concrete pump operator activate the emergency stop?
- At the end of every pour
- Whenever a person is in danger, equipment is malfunctioning, or an unsafe condition is observed (Correct answer)
- Only when the engine overheats
- When the hopper is empty
Correct answer: Whenever a person is in danger, equipment is malfunctioning, or an unsafe condition is observed
The emergency stop must be activated any time personnel are endangered, equipment is behaving unsafely, or a hazardous condition is detected.
Question 3: What should be done if a worker is struck by or trapped under the concrete pump boom?
- Immediately restart the pump to clear concrete
- Activate emergency stop, call 911, and do not move the victim unless directed by emergency responders (Correct answer)
- Attempt to lift the boom manually
- Continue the pour and address the injury after work
Correct answer: Activate emergency stop, call 911, and do not move the victim unless directed by emergency responders
In a struck-by incident, immediately stop all operations, call 911, and avoid moving the victim to prevent further injury.
Question 4: What is the correct response if a concrete pipeline suddenly bursts during pumping?
- Increase pump pressure to push the clog through
- Immediately stop the pump, relieve pressure, and evacuate the hazard zone (Correct answer)
- Cap the burst end with your hand while shutting down
- Reduce pump speed and continue operation
Correct answer: Immediately stop the pump, relieve pressure, and evacuate the hazard zone
A burst pipeline releases high-pressure concrete that can cause serious injuries; stop the pump, relieve pressure, and clear all personnel from the area.
Question 5: Which document must be completed after any on-site accident or near-miss involving a concrete pump?
- Purchase order
- Incident/accident report (Correct answer)
- Daily concrete delivery ticket

Correct answer: Incident/accident report
An incident or accident report must be completed after any on-site accident or near-miss to document the event and support regulatory compliance.
Question 6: What is the primary hazard during a concrete pump rollover incident?
- Concrete spilling onto the road
- Operator crush injury and potential fuel/hydraulic fluid fire (Correct answer)
- Loss of the pump warranty

Correct answer: Operator crush injury and potential fuel/hydraulic fluid fire
During a rollover, the greatest risks are the operator being crushed and fire from ruptured fuel or hydraulic lines.
