Alberta HET First Period AIT Exam
1.
A first-year apprentice is preparing to grind metal without eye protection. What is the best immediate
response?
A. Allow them to continue since it is a quick job
B. Stop the task and require approved safety glasses or face shield before grinding
C. Tell them to stand farther away from the grinder
D. Reduce grinder speed so sparks are smaller
, Page 2 of 114
Answer: B
Rationale: Grinding produces flying debris that can cause serious eye injury; PPE must be worn.
2.
A technician uses a torque wrench but stores it without resetting to minimum value. What problem can
result?
A. The wrench becomes heavier
B. Calibration may be affected and future torque readings may be inaccurate
C. It will tighten bolts automatically
D. The wrench will measure in foot-pounds instead of Newton-meters
Answer: B
Rationale: Proper torque wrench storage prevents spring fatigue and maintains accuracy.
3.
A loader is overheating, but coolant level is correct and the fan belt is tight. What should be checked
next?
A. Battery voltage

B. Radiator fins for blockage and restricted airflow
C. Starter motor operation
D. Track tension adjustment
Answer: B
Rationale: Blocked radiator fins reduce heat transfer and are a common overheating cause.
4.
An apprentice attempts to loosen a bolt using the wrong size wrench that slips. What is the best
correction?
A. Use more force with the same wrench
B. Use the correct size tool to prevent rounding fasteners and hand injury
C. Strike the wrench with a hammer harder
D. Apply grease to the bolt head
Answer: B
Rationale: Proper tool selection prevents damage to fasteners and improves safety.
5.

A hydraulic system is being serviced, and the technician disconnects a hose without relieving pressure.
What is the main hazard?
A. Reduced engine power
B. High-pressure fluid injection injury
C. Increased battery drain
D. Transmission slipping
Answer: B
Rationale: Hydraulic fluid under pressure can penetrate skin and cause severe injury.
6.
A battery is being tested with a multimeter, but the leads are placed incorrectly. What could happen?
A. Better voltage reading accuracy
B. Incorrect reading or possible meter damage
C. The battery will charge itself
D. The alternator will stop producing voltage
Answer: B
Rationale: Incorrect meter use produces false readings and can damage test equipment.
