Which of the following is the primary purpose of a fall protection system?
A) To make climbing easier
B) To prevent injury or death from falls
C) To hold tools while working
D) To increase worker speed
B) To prevent injury or death from falls
Rationale: Fall protection systems are designed to prevent serious injuries
or fatalities when working at heights, according to Alberta Occupational
Health and Safety (OHS) regulations.
Question 2: Structural Steel
Which steel shape is most commonly used for beams in construction?
A) Angle
B) Channel
C) Wide Flange (W)
D) Plate
C) Wide Flange (W)
Rationale: Wide flange beams provide high load-bearing capacity and are
commonly used in building construction for structural support.
,Question 3: Rigging
What is the safe working load (SWL) of a sling?
A) Maximum load a sling can carry
B) Maximum load allowed for safety
C) Breaking strength of the sling
D) Weight of the sling itself
B) Maximum load allowed for safety
Rationale: SWL is the maximum load a lifting device or sling can safely
handle under normal conditions, ensuring a safety factor is maintained.
Question 4: Welding Practices
Which welding process uses a consumable electrode and an inert gas shield?
A) Shielded Metal Arc Welding (SMAW)
B) Gas Tungsten Arc Welding (GTAW/TIG)
C) Gas Metal Arc Welding (GMAW/MIG)
D) Oxy-Acetylene Welding
C) Gas Metal Arc Welding (GMAW/MIG)
Rationale: GMAW, or MIG welding, uses a consumable wire electrode and
an inert gas such as argon or CO₂ to protect the weld pool from
contamination.
Question 5: Blueprint Reading
On a structural drawing, what does “CL” typically stand for?
A) Column Line
B) Centre Line
C) Clamp Location
D) Corner Level
B) Centre Line
Rationale: CL is a standard abbreviation on drawings indicating the center
line of a structural member, used for alignment and layout.
,Question 6: Tools & Equipment
What is the primary purpose of a torque wrench?
A) To measure length
B) To tighten bolts to a specific tension
C) To drill holes
D) To cut metal
B) To tighten bolts to a specific tension
Rationale: Torque wrenches are designed to apply a specific torque to
fasteners, ensuring connections are neither too loose nor over-tightened.
Question 7: Safety Regulations
Which PPE is mandatory when cutting or grinding steel?
A) Hard hat only
B) Gloves only
C) Eye protection, gloves, and hearing protection
D) Steel-toed boots only
C) Eye protection, gloves, and hearing protection
Rationale: CuFng and grinding steel produces sparks and noise; proper
PPE protects against eye injuries, hand injuries, and hearing damage.
Question 8: Structural Steel Connections
Which bolt type is commonly used for structural connections requiring high
strength?
A) Carriage bolt
B) A325 bolt
C) Lag bolt
D) Machine screw
B) A325 bolt
Rationale: A325 bolts are high-strength structural bolts commonly
specified in steel construction for critical connections.
, Question 9: Rigging
Which rigging hardware is rated for overhead lifting?
A) Shackles and slings
B) Rope and duct tape
C) Chains with rust
D) Wire without inspection
A) Shackles and slings
Rationale: Only hardware designed, rated, and inspected for overhead
lifting should be used to ensure safety.
Question 10: Welding Practices
What is the main purpose of preheating steel before welding?
A) To make steel softer
B) To reduce risk of cracking
C) To improve color of weld
D) To save electricity
B) To reduce risk of cracking
Rationale: Preheating reduces thermal stress and prevents cracking in
carbon and alloy steels during welding.
Question 11: Blueprint Reading
A “Detail 5/A-101” on a drawing refers to:
A) The fifth page of all drawings
B) Detail number 5 on sheet A-101
C) A revision number
D) Beam size
B) Detail number 5 on sheet A-101
Rationale: This notation directs the worker to a specific detail view on a
specific drawing sheet.
Question 12: Tools & Equipment
Which tool is designed specifically for checking flatness of a surface?
