Instrumentation and Control Technician (447A) Red Seal Exam in British Columbia (BC)

Certifying authority: SkilledTradesBC (formerly ITA BC). Last checked 2026-09-14.

Certification is voluntary in British Columbia (BC)

This trade is not on British Columbia (BC)’s compulsory list, so you may work in it without a certificate. The Red Seal still travels across Canada as a recognised credential, and employers frequently ask for it — but in British Columbia (BC) it is a qualification, not a licence.

Sample Question 1 of 3
While calibrating a level transmitter inside a crude oil tank farm dyke at a Hardisty terminal, a technician's personal monitor goes into a high H2S alarm and the area beacon starts flashing. The wind sock on the nearby pipe rack shows the wind blowing from the north. In what order should the technician respond?
A) Report at the muster point for the count; stop work and make the job safe; return only when the all-clear is given; then move upwind or crosswind out of the area
B) Stop work and make the job safe; report at the muster point for the count; move upwind or crosswind out of the area; then return only when the all-clear is given
C) Stop work and make the job safe; move upwind or crosswind out of the area; report at the muster point for the count; then return only when the all-clear is given
D) Move upwind or crosswind out of the area; return only when the all-clear is given; stop work and make the job safe; then report at the muster point for the count
Correct answer: C

On a gas alarm, the technician stops work and leaves the job in a safe state, which takes seconds, then moves upwind or crosswind out of the gas, reports at the muster point for the head count, and goes back only on the all-clear. Going to the muster point through the gas or returning before the all-clear risks a fatal exposure. The other options use the same steps in the wrong order: A does 'report at the muster point for the count' before 'stop work and make the job safe', B does 'report at the muster point for the count' before 'move upwind or crosswind out of the area', and D does 'return only when the all-clear is given' before 'stop work and make the job safe'.

Sample Question 2 of 3
After its failed 24 VDC power supply was replaced with a spare from stores, a flow computer at a meter station resets several times a day. The resets happen only when the SCADA radio transmits, and the event log shows a low-voltage restart each time. The spare supply is rated 1.0 A, while the flow computer and radio together draw up to 2.4 A when the radio transmits. What is the most likely cause?
A) The radio's antenna cable is damaged and is shorting the 24 VDC supply to ground
B) The spare supply is too small, so its output voltage sags whenever the radio keys
C) The radio is putting RF energy into the flow computer and corrupting its memory
D) The flow computer's firmware has a fault that the power supply change has exposed
Correct answer: B

The event log records a low-voltage restart each time the radio keys, and the load then reaches 2.4 A against a 1.0 A supply, so the supply goes into current limit and its voltage collapses. A supply sized for the full load is needed. RF upset would not log low voltage, and a shorted cable would act all the time. A firmware fault does not explain a sag tied to the radio's load.

Sample Question 3 of 3
A smart positioner on a valve at a Saint John refinery shows a steady 3% difference between its travel setpoint and its feedback at every point from 0 to 100%. A technician finds the feedback arm's clamp on the stem connector has slipped since the last calibration. What should be done?
A) Increase the actuator's supply pressure to push it the last 3%
B) Raise the positioner's gain until that steady 3% difference disappears fully
C) Change the valve's characterization curve to remove the offset
D) Re-secure the feedback linkage and recalibrate the positioner's travel
Correct answer: D

A slipped feedback clamp shifts the position the positioner thinks the valve is in, giving a steady offset everywhere. The linkage is re-secured at the right point and the travel calibration redone. Gain, characterization or supply pressure cannot correct a feedback reference that has moved.
