ALBERTA MILLWRIGHT (INDUSTRIAL MECHANIC) RED SEAL EXAM – QUESTIONS AND ANSWERS |
VERIFIED AND WELL DETAILED ANSWERS | PLUS RATIONALES | GUARANTEED PASS | LATEST EXAM UPDATE
Core Domains:
1. Common Occupational Skills (Safety, Tools, Measuring, Layout, and Welding)
2. Rigging, Hoisting, Lifting, and Moving
3. Mechanical Power Transmission (Prime Movers, Shafts, Bearings, Seals, Couplings, Clutches, Brakes, Chains,
Belts, and Gears)
4. Shaft Alignment (Rough, Dial, and Laser)
5. Material Handling and Process Systems (Pumps, Compressors, Fans, Blowers, Conveyors, and Piping)
6. Fluid Power Systems (Hydraulics, Pneumatics, and Vacuum)
7. Preventative and Predictive Maintenance (Vibration Analysis, Balancing, and NDT)
8. Installation and Commissioning (Equipment Installation, Leveling, and Decommissioning)
Introduction:
This comprehensive examination is designed to rigorously assess the competency of candidates for the Alberta
Industrial Mechanic (Millwright) Red Seal endorsement. It evaluates a journey-level understanding of the trade,
from foundational principles to complex, real-world applications. The assessment covers a broad spectrum of
skills including the interpretation of engineered drawings, the application of mathematical formulas for precise
layout, the correct installation and maintenance of piping systems, and adherence to stringent safety and
regulatory codes. The exam employs a multiple-choice and scenario-based format, placing a heavy emphasis
on practical decision-making, troubleshooting, and the ability to apply theoretical knowledge in a field setting.
Candidates are expected to demonstrate not only technical proficiency but also sound judgment, ethical
conduct, and a commitment to safety, all of which are paramount for a Red Seal Millwright.
,SECTION ONE: QUESTIONS 1 - 100
1. According to the Alberta OHS Code, what is the minimum distance that a portable ladder must extend
above the landing surface when used for access?
A. 600 mm
B. 900 mm
C. 1.2 m
D. 1.5 m
🟢B
🔴 Explanation: The Alberta OHS Code specifies that a portable ladder used for access must extend at least
900 mm (3 feet) above the landing surface to provide a safe handhold for the user when stepping onto or off
the ladder .
2. When using a mobile crane, who is the only person authorized to give hand signals to the operator?
A. Any worker on site
B. The designated signal person
C. The site supervisor
D. The rigger
🟢B
🔴 Explanation: Only a designated, qualified signal person is authorized to give hand signals to a crane
operator. This ensures clear and consistent communication to prevent accidents during lifting operations .
3. What is the primary purpose of a lockout/tagout (LOTO) procedure?
A. To increase machine efficiency
B. To prevent unauthorized use of machinery
,C. To ensure the machine is lubricated
D. To prevent accidental startup during maintenance
🟢D
🔴 Explanation: The lockout/tagout procedure is a critical safety protocol designed to prevent the accidental
startup of machinery or the release of hazardous energy during maintenance or repair activities, thereby
protecting workers from serious injury .
4. What is the maximum allowable slope for a Type 1 wooden ramp used for access?
A. 1:1
B. 1:3
C. 1:6
D. 1:12
🟢B
🔴 Explanation: A Type 1 wooden ramp, which is used for access, typically has a maximum allowable slope of
1:3. This is a standard safety requirement to prevent slipping and ensure stability .
5. What is the primary advantage of using a laser alignment tool over a dial indicator for shaft alignment?
A. It is less expensive
B. It is faster and provides more accurate, repeatable results
C. It does not require any setup
D. It is only used for horizontal machines
🟢B
🔴 Explanation: Laser alignment systems are faster to set up and provide highly accurate and repeatable
measurements. They automatically compensate for sag and can perform complex alignment calculations,
, making them superior for precision alignment tasks .
6. What is the recommended clearance angle on a high-speed steel (HSS) lathe tool?
A. 5°
B. 8°
C. 12°
D. 20°
🟢B
🔴 Explanation: For general purpose machining, a clearance angle of 8° is standard for HSS lathe tools to
prevent the tool from rubbing against the workpiece while maintaining adequate cutting edge strength .
7. What colour is the label for a Class D fire extinguisher, which is used for combustible metals?
A. Red
B. Blue
C. Yellow
D. Purple
🟢D
🔴 Explanation: Class D fire extinguishers are specifically for combustible metal fires (e.g., magnesium,
titanium). The label is typically purple, which helps quickly identify the correct extinguisher for this special
hazard .
8. What is the thread pitch of an M20 × 2.5 metric bolt?
A. 2.0 mm
B. 2.5 mm
