Topic pages open on your jurisdiction, and requirements tables show its line. You can change this on any page.

What this topic covers

This page covers lockout and other energy isolation (written procedures, personal locks and tags, verification and lock removal), safeguarding of machinery in stations and shops, the minimum distances workers and equipment must keep from energized overhead conductors, any relief from those distances for emergency work, and the electrical and gas codes and licensing rules that govern facility work, including the photovoltaic rapid shutdown requirements in the Canadian Electrical Code. Every jurisdiction requires lockout and guarding; the approach distances differ by voltage band and by jurisdiction, and only two give trained emergency workers a relief from them.

Why it matters to a fire department

These rules govern the apparatus bay, the maintenance shop, hose and SCBA servicing rooms, compressors, lifts and tire cages, and every contractor who works on the station’s electrical or gas systems. On the fireground, lockout is an emergency control, not the shop procedure, but the approach distances belong in every downed-wire, aerial-near-lines and extrication procedure: the distances in law are minimums for planned work, set for qualified judgement about voltage that a crew rarely has at night in the rain. A common mistake is to treat the regulation’s 3 m figure as the safe distance from a downed conductor; utilities and fire services use a wider public-safety zone, and the regulation’s emergency reliefs, where they exist, depend on approved training.

What every department must cover, wherever it is

  1. Write equipment-specific lockout procedures for station and shop equipment (compressors, lifts, hose and SCBA servicing machines, overhead doors, generators), with personal locks and tags, verification of zero energy and controlled lock removal, and train every member who works on them (see your jurisdiction below).
  2. Guard machinery and keep guards in place: point-of-operation guards, start and stop controls, automotive pits and tire inflation cages; use the current edition as the design basis where the regulation names an older one (CSA Z432:23) (see below).
  3. Know your jurisdiction’s limits of approach to energized overhead conductors for each voltage band, for people and for equipment such as aerial devices and ladders, and write them into downed-wire, aerial and extrication procedures (see the tables below).
  4. Know whether your jurisdiction gives emergency workers any relief from the approach distances; only British Columbia and Newfoundland and Labrador do, and only for workers who have completed an approved course (see below).
  5. Treat any conductor of unknown voltage as the highest band in your jurisdiction (Yukon’s rule is 7 m), keep a wider public-safety zone around downed wires, and wait for the utility to de-energize and confirm (see Yukon).
  6. Use qualified, licensed trades for facility electrical and gas work, to the Canadian Electrical Code and CSA B149 code editions your jurisdiction adopts, and manage contractors’ lockout on department premises (see below and J20 Stations, Premises and Building Codes).
  7. Know the photovoltaic and energy storage rules (Section 64 of the Canadian Electrical Code, including rapid shutdown) in the edition your jurisdiction adopts, and train crews on how rooftop systems are isolated (see Nova Scotia and Ontario guidance).
  8. Apply CSA Z462:24 for electrical work in stations, including arc flash assessment, energized-work permits and qualified-person rules (CSA Z462:24).

At a glance

Distances are the general minimums for non-electrical workers and equipment near energized overhead conductors, for a distribution line of about 25 kV and for the highest band listed. Detail and other bands are in each section.

Quebec

Verified

Law. Regulation respecting occupational health and safety, Division XXI (machines, including ss. 185 to 188) and ss. 195 to 207 (lockout and other energy control methods) (Regulation respecting occupational health and safety [QC], 2026, ss. 185-207); Safety Code for the construction industry, ss. 5.2.1 to 5.2.2 (power lines) (Safety Code for the construction industry [QC], 2026, ss. 5.2.1-5.2.2).

What must be covered.

  • Lockout. Before any work in a machine’s danger zone, lockout or, failing that, another energy control method (s. 196); “Lockout must be carried out by every person having access to the danger zone of a machine” (s. 197); “lockout” means installing an individually keyed lock (s. 195); another method only after an analysis that shows equivalent safety (s. 198); written procedures for every machine (ss. 199-200), with deactivation, isolation, lockout and verification steps (s. 201); training (s. 202); written authorization and co-ordination for outside employers (ss. 203-204); the employer supplies individually keyed locks (s. 205); controlled removal of a forgotten lock (s. 206); the same rules apply to work on electrical installations (s. 207).

  • Guarding. Means of protection may not be removed except as the Division allows; control devices designed to avoid accidental start-up (ss. 186-188).

  • Power lines. No one performs work liable to bring a part, load, scaffolding, machine component or person closer than (Safety Code for the construction industry [QC], 2026, s. 5.2.1):

    Voltage between phases Minimum approach distance
    Less than 125,000 V 3 m
    125,000 to 250,000 V 5 m
    250,000 to 550,000 V 8 m
    More than 550,000 V 12 m
  • Closer work. Only if the line is turned off, the employer has an agreement with the power company on safety measures, or extensible equipment has an engineer-certified limiting device (s. 5.2.2).

Fire-service nuance.

  • No emergency relief from the approach distances. Quebec’s distances at 125 kV and above are the largest in Canada.
  • Electrical and gas installation codes and licensing sit under the Building Act and the Construction Code; they were not read for this page.

Status. Verified against the official text on 2026-10-23 (RSST ss. 185-207 and Construction Code ss. 5.2.1-5.2.2 read in the consolidations of 2026-07-01). Code adoption and licensing were not checked.

New Brunswick

Verified

Law. General Regulation 91-191, ss. 239 to 243 (lockout and guarding) and s. 289 (working distances for unqualified persons) (General Regulation: Occupational Health and Safety Act [NB], 2026, ss. 239-243, 289).

What must be covered.

  • Lockout. Lockable energy-isolating devices, personal safety locks and keys, and a written lockout procedure with training; work starts only after a zero energy state is confirmed and a personal lock and a tag with name, date and time are applied (s. 239); a code of practice where lockout is not appropriate (s. 240).

  • Guarding. Ss. 241 to 243.

  • Limits of approach. An employee who is not a qualified person does no work liable to bring any person or object closer to an energized utility line or utility line equipment than (s. 289(1)):

    Phase-to-phase voltage Distance
    Up to 750 V 900 mm
    750 V to 100,000 V 3.6 m
    100,001 V to 250,000 V 5.2 m
    250,001 V to 345,000 V 6.1 m
  • Closer work. The employer contacts the authority that owns or operates the line and ensures it is de-energized or adequately insulated or guarded before the work begins (s. 289(2)).

Fire-service nuance.

  • No emergency relief from s. 289. New Brunswick’s distances in the 750 V to 100 kV band (3.6 m) are larger than most jurisdictions’.
  • Electrical installation and gas codes and licensing were not read for this page.

British Columbia

Verified

Law. Occupational Health and Safety Regulation, Part 10 (lockout, ss. 10.1 to 10.12), Part 12 (tools, machinery and equipment, ss. 12.2-12.3) and Part 19 (electrical safety, ss. 19.24 to 19.29) (Occupational Health and Safety Regulation [BC], 2026, ss. 10.1-10.12, 12.2-12.3, 19.24-19.29). Codes: the BC Electrical Code adopted under the Safety Standards Act and the Electrical Safety Regulation (Technical Safety BC, 2024).

What must be covered.

  • Lockout. When lockout is required (s. 10.3); lockout procedures available to every worker who works on the equipment, with personal locks marked to identify the person applying them (s. 10.4); verification of isolation (s. 10.6); lock removal (s. 10.8); group lockout (s. 10.9); alternatives to lockout (s. 10.10); work on energized equipment (s. 10.12).

  • Guarding. Safeguards on machinery (s. 12.2), designed to CSA Z432-94 (s. 12.3).

  • Limits of approach. People, tools, machines, material and equipment keep at least these distances from exposed energized conductors (s. 19.24.1, Table 19-1A):

    Voltage (phase to phase) Minimum approach distance
    Over 750 V to 75 kV 3 m (10 ft)
    Over 75 kV to 250 kV 4.5 m (15 ft)
    Over 250 kV to 550 kV 6 m (20 ft)
  • Passing under. Smaller clearances apply when moving equipment under conductors without doing other work: 2 m, 3 m and 4 m for the same bands (s. 19.24.2, Table 19-1B).

  • Closer work. Written assurance from the power system owner where the distances cannot be kept (s. 19.25); qualified workers may work closer only with the owner’s authorization and acceptable procedures (s. 19.29).

  • Electrical code. CSA C22.1-24, the 26th edition of the Canadian Electrical Code, is adopted as the BC Electrical Code effective 2025-03-04 (Technical Safety BC, 2024).

Fire-service nuance.

  • The relief, verbatim. “Sections 19.24 to 19.27 do not apply to emergency actions close to energized high voltage electrical equipment or conductors carried out by workers who have undergone a course of instruction approved by the Board” (s. 19.28(1)). During emergency actions, all reasonable precautions are taken where practicable: restricting entry, a safety watcher, no one but the operator touching moving equipment, and the operator at the controls on the machine or a bonded mat (s. 19.28(2)).
  • The relief depends on a Board-approved course; a department that has not trained its members to one has no relief.
  • Part 31 requires written procedures for electrical emergencies where the service responds to them (s. 31.5(2)); see J12 Fire Service OHS Rules and Fireground Operations.
  • WorkSafeBC reports amendments on automotive lifts in Part 12 due 2027-03-01 (WorkSafeBC, 2026b).

  • Lockout. A written, equipment-specific lockout procedure; zero energy state; locks and tags; verification by a competent person (ss. 51-54).

  • Guarding. Safeguards on machinery (s. 87), start and stop controls (s. 88), automotive pits (s. 91) and tire cages for split-rim inflation (s. 92).

  • Electrical work. Installations to CSA C22.1 and electrical work by competent persons (Part 11).

  • Limits of approach. Minimum approach distances to energized lines (s. 126):

    Voltage Minimum approach distance
    Below 750 V 1 m
    750 V to 69 kV 3 m
    69 kV to 138 kV 5 m
    Above 138 kV 6 m
    Voltage unknown 6 m
  • Electrical code. The 2024 Canadian Electrical Code, Part 1, CSA C22.1:24, adopted without amendment from 2024-07-02 under the Electrical Code Regulations made under s. 6 of the Electrical Installation and Inspection Act; its Section 64 updates the solar photovoltaic rules, including rapid shutdown, and the energy storage rules (Nova Scotia Department of Labour, Skills and Immigration, 2024a).

Fire-service nuance.

  • No emergency relief from s. 126. Write the s. 126 table into the downed-wire procedure alongside the utility’s responder guidance and a wider public-safety zone.
  • Lockout at an emergency scene is a general-duty matter; the written procedures in Part 6 govern stations and shops.
  • Gas installations follow CSA B149.1 as adopted under provincial gas legislation.

Status. Verified against the Registry of Regulations consolidation (amended to N.S. Reg. 53/2013): Parts 6, 8, 11 and s. 126 read on 2026-10-24; the code adoption read in the official bulletin on 2026-10-23.

    250,001 V to 345,000 V 6.1 m
  • Higher voltages and closer work. Above 345 kV, the utility’s instructions (s. 36.21); closer work only after contacting the utility and having the line de-energized or guarded (s. 36.22).

Fire-service nuance.

  • No emergency relief.
  • Electrical inspection and licensing were not read for this page.

Status. Verified against the official text on 2026-10-23 (consolidated to 2025-01-01). Code adoption was not checked.

Newfoundland and Labrador

Verified

Law. Occupational Health and Safety Regulations, 2012, Part VIII (machine guarding, ss. 88 to 91), Part IX (lockout, ss. 127 to 137) and ss. 497 to 501 (work near energized conductors) (Occupational Health and Safety Regulations, 2012 [NL], 2026, ss. 88-91, 127-137, 497-501).

What must be covered.

  • Lockout. Personal locks marked with the worker’s name, the equipment and the date; no combination locks; group lockout and shift-change procedures (Part IX).

  • Guarding. Part VIII.

  • Limits of approach. (s. 498(3)):

    Voltage Minimum distance
    Over 750 V to 75 kV 3 m
    Over 75 kV to 250 kV 4.5 m
    Over 250 kV to 550 kV 6 m
  • Default clearance. A 5.5 m default for material, scaffolds and cranes near conductors where the utility gives no written clearance (s. 498(2)).

Fire-service nuance.

  • The relief, verbatim. “Sections 497 to 500 do not apply to an emergency action close to energized high voltage electrical equipment or conductors that is carried out by a worker who has undergone a course of instruction approved by the minister” (s. 501(1)). The precautions in s. 501(2) still apply: restricted entry, a safety watcher, and no contact with moving equipment.
  • As in British Columbia, the relief depends on an approved course.
  • Electrical installation codes and licensing were not read for this page.

Status. Verified against the official text on 2026-10-23 (consolidated to NLR 48/26).

Yukon

Verified

Law. Workplace Health and Safety Regulations, Part 3 (lockout), Part 7 (machinery and machinery guarding, s. 7.02) and Part 9 (electrical safety, ss. 9.18 to 9.22) (Workplace Health and Safety Regulations [YT], 2022, ss. 3.01-3.10, 7.02, 9.18-9.22).

What must be covered.

  • Lockout. Part 3, with a group lockout procedure when 3 or more workers or more than 4 isolating devices are involved.

  • Guarding. Safeguards to CSA Z432-04 (s. 7.02).

  • Limits of approach. The voltage is determined accurately and these distances kept by workers and equipment (s. 9.18(1), Table 9-1):

    Voltage (phase to phase) Limit of approach
    Up to 750 V 1.0 m (3 ft)
    750 V to 40 kV 3.0 m (10 ft)
    69 kV, 72 kV 3.5 m (12 ft)
    138 kV, 144 kV 4.0 m (13 ft)
    230 kV, 260 kV 5.0 m (16 ft)
    500 kV 7.0 m (23 ft)
  • Unknown voltage. “Where the voltage of any energized equipment or conductor cannot or has not been determined, the limit of approach of 7.0 m (23 ft.) shall be maintained” (s. 9.18(2)).

  • Closer work. Written assurance from the public utility where the distance cannot be kept (s. 9.19).

Fire-service nuance.

  • No exemption, only precautions. “During emergency actions all reasonable precautions shall be taken to control the hazards”, including restricting entry, a safety watcher, no one touching moving equipment, and the operator on the machine or a bonded mat (s. 9.22(1)). Only journeyperson electrical workers and those under their direct supervision may work within the distances, with the owner’s authorization (s. 9.22(2)).
  • The 7 m unknown-voltage rule is a sound default for any downed-wire procedure.

Status. Verified against the board’s official rendering of the regulations: Parts 3, 7 and 9 read on 2026-10-24. Code adoption was not checked.
