General requirement

10.2  If the unexpected energization or startup of machinery or equipment or the unexpected release of an energy source could cause injury, the energy source must be isolated and effectively controlled.

When lockout required

10.3   (1)If machinery or equipment is shut down for maintenance, no work may be done until

(a)all parts and attachments have been secured against inadvertent movement,

(b)where the work will expose workers to energy sources, the hazard has been effectively controlled, and

(c)the energy isolating devices have been locked out as required by this Part.

(2)If machinery or equipment is in use for normal production work, subsection (1) applies if a work activity creates a risk of injury to workers from the movement of the machinery or equipment, or exposure to an energy source, and the machinery or equipment is not effectively safeguarded to protect the workers from the risk.

Lockout procedures

10.4   (1)When lockout of energy isolating devices is required, the devices must be secured in the safe position using locks in accordance with procedures that are made available to all workers who are required to work on the machinery or equipment.

(2)The employer must ensure that each worker required to lock out has ready access to sufficient personal locks to implement the required lockout procedure.

(3)Combination locks must not be used for lockout.

(4)Each personal lock must be marked or tagged to identify the person applying it.

(5)Procedures must be implemented for shift or personnel changes, including the orderly transfer of control of locked out energy isolating devices between outgoing and incoming workers.

(6)If the use of a personal lock is not practicable for lockout, another effective means, if approved by the Board, may be used in place of a personal lock to secure an energy isolating device in the safe position.

Access to energy isolating devices

10.5  When an energy isolating device is locked out, the lock must not prevent access to other energy isolating devices supplying machinery or equipment that could cause injury to workers.

Checking locked out equipment

10.6   (1)Effective means of verifying lockout must be provided and used.

(2)Before commencing work, a worker must verify that all energy sources have been effectively locked out.

Worker responsibilities

10.7  Each worker who works on machinery or equipment requiring lockout is responsible for

(a)locking out the energy isolating devices before starting work, except as provided by section 10.9,

(b)removing personal locks on the completion of the worker’s work, and

(c)maintaining immediate control of the key(s) to personal locks throughout the duration of the work.

[am. B.C. Reg. 116/2022, App. B, s. 9.]

Removal of locks

10.8   (1)A personal lock must only be removed by the worker who installed it, or if this is not possible, the matter must be referred to the supervisor or manager in charge, who will be responsible for its removal.

(2)The supervisor or manager in charge must

(a)make every reasonable effort to contact the worker who installed the lock, and

(b)ensure that the machinery or equipment can be operated safely before removing the lock.

(3)A worker must be notified at the start of the worker’s next shift if the worker’s personal lock(s) have been removed since the worker’s previous shift.

[am. B.C. Reg. 116/2022, App. B, s. 9.]

Group lockout procedure

10.9   (1)If a large number of workers are working on machinery or equipment or a large number of energy isolating devices must be locked out, a group lockout procedure that meets the requirements of subsections (2) to (7) may be used.

(2)In a group lockout procedure 2 qualified workers must be responsible for

(a)independently locking out the energy isolating devices,

(b)securing the keys for the locks used under paragraph (a) with personal locks or other positive sealing devices acceptable to the Board, and

(c)completing, signing and posting a checklist that identifies the machinery or equipment components covered by the lockout.

(3)Before commencing work each worker working on the locked out components must apply a personal lock to the key securing system used in subsection (2) (b).

(4)Workers may lock out a secondary key securing system if 2 qualified workers lock out the primary key securing system and place their keys in the secondary system.

(5)On completion of the worker’s work, each worker referred to in subsections (3) and (4) must remove the worker’s personal lock from the key securing system.

(6)When the requirements of subsection (5) have been met and it has been determined that it is safe to end the group lockout, 2 qualified workers must be responsible for removing their personal locks or the positive sealing device(s) from the key securing system or systems containing the keys for the locks used under subsection (2) (a), and once those keys are released, the system is no longer considered to be locked out.

(7)The written group lockout procedure must be conspicuously posted at the place where the system is in use.

[am. B.C. Reg. 116/2022, App. B, s. 9.]

Alternative procedures

10.10   (1)If lockout of energy isolating devices as required by section 10.3 is not practicable,

(a)in the case of a power system as defined in Part 19 (Electrical Safety), the requirements of that Part must be followed,

(b)in the case of mobile equipment, the requirements of Part 16 must be followed,

(c)in the case of machinery or equipment designed and equipped with effective control system isolating devices, the devices must be locked out as required by sections 10.4 to 10.9, and 10.10 (2), and

(d)in an emergency, the energy isolating devices or control system devices must be effectively controlled to prevent inadvertent start up or hazardous energy release.

(2)Control system isolating devices and the procedures for using them must be approved in writing by the Board, and must be used by workers qualified and authorized to carry out the work.

[am. B.C. Reg. 139/2021, App. D, s. 4.]

Locks not required

10.11  The application of a lock is not required under section 10.3 or 10.10 if

(a)the energy isolating device is under the exclusive and immediate control of the worker at all times while working on the machinery or equipment, or

(b)a tool, machine or piece of equipment which receives power through a readily disconnected supply, such as an electrical cord or quick release air or hydraulic line, is disconnected from its power supply and its connection point is kept under the immediate control of the worker at all times while work is being done.

Work on energized equipment

10.12  If it is not practicable to shut down machinery or equipment for maintenance, only the parts which are vital to the process may remain energized and the work must be performed by workers who

(a)are qualified to do the work,

(b)have been authorized by the employer to do the work, and

(c)have been provided with and follow written safe work procedures.
