The Red Seal Ironworker (Reinforcing) Interprovincial (IP) exam certifies rebar ironworkers (rodworkers) who fabricate, place, tie, and stress reinforcing steel for concrete structures. The exam has roughly 120 four-option multiple-choice questions and requires 70% to pass; provincial exam fees commonly run about $100-170 CAD. Content emphasizes the largest block, placing and tying reinforcing steel (concrete cover, chairs and supports, tie patterns, lap splices and couplers), plus reading placing drawings and bar schedules, CSA G30.18 rebar fabrication and bending, post-tensioning systems (unbonded monostrand and bonded grouted tendons, stressing and elongation), and welded wire mesh, accessories and pre-pour inspection. This free prep includes 100 research-based practice questions with explanations and an AI tutor.

1Before lifting a bundle of 20M reinforcing bars with a crane, what is the most important reason an ironworker confirms the bundle is choked with two wraps and the load is balanced?
A.To reduce the weight the crane must lift
B.To prevent the bars from sliding out of the choker and falling
C.To allow the bundle to be lifted faster
D.To avoid bending the bars during the lift
Explanation: Long, smooth round bars can slip free of a single-wrap choke, so reinforcing bundles are double-wrapped (double-choked) and balanced at the lift point so no bars slide out and drop on workers below. This is a fundamental rigging-safety control on a reinforcing job.
2An ironworker is tying rebar mats and develops a repetitive-strain injury in the wrist and forearm. Which control most directly reduces this hazard?
A.Wearing a high-visibility vest
B.Using a power tying tool or a tie-wire twister with a comfortable handle
C.Increasing the tie-wire gauge
D.Tying every intersection instead of staggering ties
Explanation: Hand-tying thousands of intersections is a leading cause of repetitive-strain injury in reinforcing ironwork. A battery-powered rebar tying tool or an ergonomic twister greatly reduces the wrist motion and force, controlling the hazard at its source.
3Protruding vertical dowels and starter bars on a slab edge are a recognized impalement hazard. What is the required control?
A.Paint the bar ends fluorescent orange
B.Bend all the bars over flat to the deck
C.Cap the exposed ends with rebar caps rated for impalement protection or guard them
D.Cut the dowels off below deck level
Explanation: Exposed projecting reinforcing must be guarded against impalement; the standard control is rebar protective caps designed and rated for impalement protection (not just colour caps), or troughs/covers over the field of bars. This is required wherever workers could fall or work over the ends.
4When hand signalling a crane to set a bundle of reinforcing steel, who must be designated as the signaller?
A.Any worker who can see the load
B.One trained, designated signaller using standard signals
C.The crane operator's helper only
D.Two workers signalling at once for redundancy
Explanation: Only one trained, clearly identified signaller may direct the crane at any time, using recognized standard hand signals, so the operator receives unambiguous direction. Anyone may give an emergency stop, but only the designated signaller directs the lift.
5An ironworker must calculate the approximate weight of one 12 m length of 20M reinforcing bar (mass ≈ 2.355 kg/m) to plan a lift. What is the closest weight?
A.About 14 kg
B.About 28 kg
C.About 47 kg
D.About 71 kg
Explanation: 20M bar has a mass of about 2.355 kg/m, so 12 m weighs 12 × 2.355 ≈ 28.3 kg. Knowing per-metre bar masses (10M ≈ 0.785, 15M ≈ 1.570, 20M ≈ 2.355 kg/m) lets ironworkers size bundles and rigging correctly.
6While placing top mat steel on a suspended deck, an ironworker works near an unguarded slab edge 4 m above grade. What fall-protection arrangement is appropriate?
A.No protection is needed because the worker is tying steel
B.A travel-restraint or fall-arrest system connected to an adequate anchor
C.Holding onto the rebar mat for support
D.A warning line set 1 m from the edge with no other control
Explanation: Work near an unguarded edge above the trigger height (commonly 3 m on construction) requires a fall-protection system — guardrails, travel restraint, or fall arrest tied to an adequate anchor. Reinforcing mats are not anchors and tying steel does not exempt the worker.
7What is the primary purpose of a tag line on a bundle of reinforcing steel being hoisted by crane?
A.To add lifting capacity to the crane
B.To let workers control the load's orientation and swing from a safe distance
C.To measure the lift height
D.To act as the main load-bearing sling
Explanation: A tag line is a rope attached to a suspended load so workers can guide and steady it from a safe position without standing under or beside the load. It controls swing and rotation but carries no lifting load.
8A sling angle is reduced from 60° to 30° from horizontal on a two-leg lift of a rebar bundle. What happens to the tension in each sling leg?
A.It decreases
B.It stays the same
C.It increases
D.It becomes zero
Explanation: As the sling angle to horizontal decreases, the tension in each leg increases sharply for the same load, because the horizontal force component grows. At 30° the tension is roughly double the load-share at 90°, which is why flat sling angles are dangerous.
9Which personal protective equipment is specifically important when flame-cutting or torch-cutting reinforcing bar in the field?
A.Hearing protection only
B.Cut-resistant cotton gloves
C.Shaded eye protection and flame-resistant clothing
D.A dust mask
Explanation: Oxy-fuel cutting of rebar produces intense light, sparks, and molten slag, so shaded eye protection (proper torch goggles/shade) and flame-resistant clothing are required to protect the eyes and skin from burns and radiation.
10Before stressing operations begin on a post-tensioning job, why must workers stay clear of the area directly behind the stressing jack and anchorage?
A.The hydraulic pump is very loud there
B.A strand or wedge failure can eject material with lethal force along the tendon line
C.The concrete is still wet behind the anchor
D.The jack blocks the worker's view of the deck
Explanation: During stressing the tendon stores enormous energy. If a strand, wedge, or anchorage fails, components can be ejected at high velocity along the line of the tendon behind the jack — a known fatal hazard. Workers must never stand in line behind the jack while stressing.
