NSC Quality Control & Inspection 3 — Questions and Answers
Question 1: A forklift operator notices the horn does not work during the pre-operation inspection. What is the appropriate response?
- Operate the forklift but avoid areas where the horn would be needed
- Attach a manual bell as a temporary substitute
- Remove the forklift from service until the horn is repaired (Correct answer)
- Use verbal warnings instead of the horn for the shift
Correct answer: Remove the forklift from service until the horn is repaired
A non-functioning horn is a safety defect; the forklift must be taken out of service until repaired, as the horn is a required safety device per OSHA standards.
Question 2: During inspection, the operator finds the forklift's load backrest extension is missing. What should occur?
- Operate only with loads that do not exceed backrest height
- Tag out the forklift and notify the supervisor (Correct answer)
- Secure loads with strapping as a substitute safety measure
- Only remove from service if loads will exceed 500 lbs
Correct answer: Tag out the forklift and notify the supervisor
The load backrest extension prevents loads from falling onto the operator; its absence requires the unit be removed from service and reported.
Question 3: What is the primary purpose of inspecting the forklift's data plate during a pre-operation check?
- To verify the forklift's fuel type
- To confirm the operator's certification number
- To check load capacity and attachment configurations (Correct answer)
- To find the last service date
Correct answer: To check load capacity and attachment configurations
The data plate provides critical load capacity information including rated capacity with and without attachments, which the operator must know before handling any load.
Question 4: Which condition of the forklift's carriage requires immediate removal from service?
- Light surface rust on the carriage bar
- Carriage bar is slightly dirty with dust
- Carriage bar is bent or cracked (Correct answer)
- Carriage bar has minor paint chipping
Correct answer: Carriage bar is bent or cracked
A bent or cracked carriage bar is a structural defect that compromises load handling safety and requires immediate removal from service.
Question 5: An operator discovers hydraulic fluid pooling beneath the forklift before a shift. The correct action is to:
- Wipe up the spill and operate cautiously, monitoring for more leaks
- Use the forklift for light loads only until maintenance can address the leak
- Remove the forklift from service and report the leak to maintenance (Correct answer)
- Add hydraulic fluid to compensate for the loss and continue the shift
Correct answer: Remove the forklift from service and report the leak to maintenance
Hydraulic fluid leaks indicate a compromised system that can lead to sudden loss of load control; the forklift must be removed from service immediately.
Question 6: During the inspection, the operator tests the service brakes and finds they feel spongy. This indicates:
- The brakes need lubrication
- There may be air in the hydraulic brake lines or fluid is low (Correct answer)
- Spongy brakes are normal on older forklifts
- The brake pads just need a brief warm-up period
Correct answer: There may be air in the hydraulic brake lines or fluid is low
Spongy brake feel typically indicates air in the hydraulic brake lines or low brake fluid, both of which reduce braking effectiveness and require maintenance.
Question 7: What is the correct procedure if a forklift is found defective at the end of one shift before the next shift begins?
- Leave a verbal message for the next operator
- Attach a defect tag and complete a written report so the next operator and maintenance are informed (Correct answer)
- Park the forklift in an out-of-the-way location as a signal it should not be used
- Allow the next shift operator to perform their own inspection and decide
Correct answer: Attach a defect tag and complete a written report so the next operator and maintenance are informed
Defective forklifts must be tagged out of service with a written defect report to ensure the next operator and maintenance personnel are clearly notified.
