1.7 Planning Work, Permits, Communication & Mentoring

Key Takeaways

  • A field-level hazard assessment is completed at the work site immediately before the task, and is re-done whenever conditions, scope or crew change.
  • Group lock-out uses a lock box: the isolation locks go on the energy sources, their keys go in the box, and every worker applies a personal lock to the box.
  • Common permits a millwright works under are hot work, confined space entry, line breaking, working at heights, excavation and energized electrical work.
  • Millwright apprenticeship in Canada is administered provincially and typically combines about four years of on-the-job hours with periodic technical training before the Red Seal exam.
  • The tell-show-do-review sequence — explain, demonstrate, supervise the apprentice doing it, then give specific feedback — is the standard structured mentoring method.

Task A-3.01 (Plans work) and Task A-4 (Uses communication and mentoring techniques, 3 exam questions) are the "soft" tasks that candidates skip and then lose marks on. The Red Seal Occupational Standard treats them as trade competencies, not optional extras.

Planning the Job

Before a millwright picks up a tool, a complete job plan answers ten questions:

#Planning questionTypical source
1What is the scope and the required end state?Work order, planner, operations
2What does the equipment documentation say?OEM manual, drawings, P&ID, equipment history in the CMMS
3What are the hazards and controls?Field-level hazard assessment, job hazard analysis, SDS
4What energy sources must be isolated and how?Lock-out procedure, isolation list, energy source drawing
5What permits are required?Site permit system
6What parts, materials and consumables are needed?Bill of materials, stores, gasket and seal kits
7What tools, rigging and access equipment are needed?Lift plan, tool list, EWP or scaffold request
8Who is doing the work, and what qualifications do they need?Crew plan, competency records
9What is the sequence, and what are the hold points?Job plan, critical path
10What is the contingency if something is seized, broken or different than expected?Spares availability, escalation contact

A field-level hazard assessment (also called a field-level risk assessment or tailboard) is completed at the work location, immediately before the work, by the crew doing it — not filled in at the shop that morning. It identifies each task step, the hazards, the controls, and who is responsible, and it must be revised whenever the scope, the conditions, the equipment or the crew changes. A pre-job toolbox talk communicates the plan to everyone involved, including operators, riggers and any other trades in the area.

Permits

PermitTriggered byCore requirements
Hot workWelding, cutting, grinding, or any spark source outside a designated areaCombustibles cleared or protected, gas testing where flammables may be present, fire watch during and for at least 30 minutes after
Confined space entryEntry into a tank, vessel, pit, silo, bin or sumpAtmospheric testing, isolation, ventilation, attendant, rescue plan (see section 1.3)
Line breakingOpening any line that has contained a hazardous substancePositive isolation, drain and purge, verified zero pressure, PPE for contents
Working at heightsWork above the regulated height without permanent guardingFall protection plan, anchor verification, rescue plan
Excavation / ground disturbanceDigging, coring, or driving anchorsUtility locates, shoring or sloping, atmospheric testing
Energized electrical workAny work inside the flash boundaryQualified electrical worker, arc-flash PPE, energized work permit

Permits are time-limited and condition-specific. They must be closed out when the work ends or the shift changes, and re-issued rather than extended by assumption.

Lock-Out Coordination and Group Lock-Out

Section 1.2 covers the mechanics of lock-out and zero energy state. Planning adds the coordination layer:

             GROUP LOCK-OUT WITH A LOCK BOX

   Energy isolation points          Lock box                Workers
   +---------------------+       +-------------+
   | Breaker  [ lock A ] |       |  key A      |  <- personal lock (millwright)
   | Valve    [ lock B ] | --->  |  key B      |  <- personal lock (electrician)
   | Blind    [ lock C ] |       |  key C      |  <- personal lock (rigger)
   +---------------------+       +-------------+
   Isolation locks stay on       Keys are captive        Each worker's own lock
   until every personal          inside the box          must come off before
   lock is removed                                       the box can be opened

Every worker exposed to the hazard applies their own personal lock and tag, and only that worker removes it. Removing another person's lock is an extreme-severity violation and is permitted only under a documented, authorized, verified-absence procedure. The plan must also state who verifies isolation, who performs the try-test, and what happens at shift change — an incoming crew applies their locks before the outgoing crew removes theirs.

Communication (A-4.01)

ChannelMillwright practice
Work orders and CMMSRecord what was actually found, what was done, parts used and readings taken. The equipment history is what makes future failure analysis possible — "fixed" is not an acceptable entry
Drawings and schematicsRedline any drawing that no longer matches the field and route it for updating; an out-of-date drawing causes the next failure
Verbal and radioUse clear, confirmed communication: state the message, have it repeated back, and use standard terminology. On lifts, use the standard crane hand signals from section 3.4 and a single designated signaller
Shift handoverCover equipment state, isolation status, work in progress, what is left to do, and anything unresolved. Verbal handover alone is not enough — write it down
Management of change (MOC)Any substitution of a part, material, setpoint or method must go through the site MOC process. Installing a "close enough" bearing or a different gasket material without MOC is a common cause of repeat failures
ReportingNear misses, unsafe conditions, and equipment defects are reported immediately, not at the end of the shift

Mentoring (A-4.02)

Journeypersons are the training system in the skilled trades. In Canada, apprenticeship is administered provincially or territorially, and the millwright program combines a period of supervised on-the-job hours — commonly around four years — with periodic in-school technical training, before the apprentice writes the certification exam. Program hours, ratios and technical training schedules differ between jurisdictions, so verify the requirements with the apprenticeship authority where you work.

Journeyperson responsibilities:

  1. Supervise within the required ratio. Provincial regulations set journeyperson-to-apprentice ratios, and an apprentice must work under the supervision of a certified journeyperson.
  2. Verify and sign off logged hours and competencies honestly. Signing for work an apprentice has not performed defeats the whole credential.
  3. Model safe behaviour. An apprentice will copy what they see, not what they are told. Skipping a lock-out once teaches more than a hundred safety talks.
  4. Give specific, timely feedback — describe the behaviour and the consequence, not the person.

The Tell-Show-Do-Review Method

StepWhat the journeyperson does
TellExplain the task, why it matters, the standard it must meet, and the hazards
ShowDemonstrate at working speed, then again slowly, narrating the key points and the reasons
DoHave the apprentice perform the task under direct supervision, intervening only for safety or to prevent damage
ReviewDebrief immediately: what went well, what to change, and confirm understanding by asking the apprentice to explain it back

Adjust for the apprentice's level: a first-year needs close supervision and narrow scope, while a fourth-year needs the whole job and the chance to plan it. Confirm understanding by having the apprentice explain or demonstrate — never by asking "do you understand?", which almost always gets a yes.
