The Red Seal Ironworker (Structural and Ornamental) exam is the interprovincial Red Seal certification for ironworkers who erect structural steel and install ornamental, precast, and curtain-wall metals. It consists of 120 four-option multiple-choice questions, allows up to four hours, and requires 70% to pass, based on the Red Seal Occupational Standard. Unlike the reinforcing stream, this trade focuses on structural steel erection and plumbing-up, bolted and welded connections (turn-of-nut, TC bolts, DTIs, slip-critical joints), rigging and hoisting, and architectural metalwork such as stairs, railings, grating, and curtain wall. Fees vary by province or territory, roughly $150-480 CAD set at registration. This free prep includes 100 research-based practice questions with explanations and an AI tutor.

1An ironworker connecting structural steel at height is required to maintain 100% tie-off. What does this mean in practice?
A.The worker may unhook from one anchor only after the steel is fully bolted
B.The worker is always attached to an anchorage by at least one lanyard at all times, including while moving
C.Tie-off is only required when working more than 9 m above grade
D.A single lanyard is sufficient because the connector is constantly moving
Explanation: 100% tie-off means a worker is continuously connected to a fall-arrest anchorage at every moment, including transitions. This is achieved with a twin-leg (Y) lanyard so one leg is always anchored while the other is repositioned, eliminating any unprotected interval.
2When a sling is rigged in a basket hitch with both legs vertical, what is its lifting capacity compared with a single vertical hitch of the same sling?
A.Equal to a single vertical hitch
B.75% of a single vertical hitch
C.Double a single vertical hitch
D.Half a single vertical hitch
Explanation: A basket hitch supports the load on two legs of the sling, so with the legs vertical the capacity is twice (200%) that of a single vertical hitch. As the basket legs spread to an angle, the capacity is reduced by the sling-angle factor.
3As the angle between a sling leg and the horizontal decreases, what happens to the tension in the sling leg for a given load?
A.It decreases
B.It stays the same because the load does not change
C.It increases
D.It depends only on the sling diameter, not the angle
Explanation: Lower sling angles increase tension in each leg. At 60 degrees the leg tension is about 1.15 times the vertical share, at 45 degrees about 1.41 times, and at 30 degrees about 2.0 times. Ironworkers avoid rigging below 30 degrees from horizontal.
4A choker hitch is generally rated at what percentage of a sling's vertical hitch working load limit?
A.50%
B.75%
C.100%
D.200%
Explanation: A choker hitch is de-rated to about 75% of the vertical WLL because the sharp bend where the sling chokes itself reduces effective strength. If the choke angle is less than 120 degrees the capacity drops even further.
5What is the primary purpose of attaching a tag line to a structural steel member being hoisted by a crane?
A.To increase the lifting capacity of the crane
B.To control rotation and positioning of the load from the ground
C.To act as the primary load-bearing sling
D.To measure the weight of the member
Explanation: A tag line is a non-load-bearing rope that lets a worker on the ground control the swing and rotation of a suspended member, keeping it from spinning into structure or workers. It allows guidance without anyone having to ride or reach under the load.
6When using a shackle to connect a sling to a load, the correct practice is to:
A.Run the load through the pin and the sling eye through the bow
B.Run the load through the bow of the shackle and place the sling on the pin
C.Side-load the shackle pin for easier alignment
D.Always use the running line on the shackle pin to spread the load
Explanation: The shackle should be loaded through the bow, with the running or moving part bearing on the bow and the standing part on the pin. Running the moving line over the pin can rotate and unscrew the pin, risking failure; shackles must also never be side-loaded.
7During a critical lift, the signal person loses sight of the load and the operator. What hand signal takes priority and may be given by anyone?
A.Hoist up slowly
B.Swing the boom
C.Emergency stop
D.Travel the crane
Explanation: Only the designated signaller normally directs the crane, but the emergency stop signal may be given by any worker who sees a hazard, and the operator must obey it immediately. Loss of communication between signaller and operator is itself a reason to stop.
8A personal fall-arrest system for an ironworker must limit the maximum arresting force on the body to no more than approximately:
A.2 kN (450 lb)
B.4 kN (900 lb)
C.8 kN (1,800 lb)
D.16 kN (3,600 lb)
Explanation: CSA Z259 and provincial regulations limit the maximum arresting force transmitted to the worker to about 8 kN (1,800 lb). Shock-absorbing lanyards are designed to deploy and keep peak force at or below this value to prevent internal injury.
9Before any structural steel erection begins, OH&S steel-erection rules require the controlling contractor to confirm what about the concrete in footings, piers, and walls supporting the steel?
A.That it has cured to at least 75% of design strength
B.That it has attained adequate strength to support the imposed loads, confirmed in writing
C.That it is no more than 7 days old
D.That the anchor rods are galvanized
Explanation: Steel erection cannot start until the controlling contractor provides written confirmation that the concrete supporting the steel has attained sufficient strength to carry the loads imposed during erection. This protects against column or anchorage failure under early loading.
10Wire rope slings must be removed from service when which of the following is found?
A.Any light surface rust on the outer wires
B.Ten randomly distributed broken wires in one rope lay, or five in one strand
C.The sling has been used on more than ten lifts
D.The sling tag lists a manufacturer no longer in business
Explanation: A wire rope sling is rejected when there are ten randomly distributed broken wires in one rope lay or five broken wires in one strand, among other criteria such as kinking, birdcaging, heat damage, or severe corrosion. These thresholds come from the rigging standards.
