PART 16
MACHINES, TOOLS AND ROBOTS


DIVISION 1
Application

16.1 This Division applies to every workplace where a machine or tool is used.
Safe work procedures
16.2(1) An employer must
(a) develop and implement safe work procedures respecting all machines and tools used in the workplace;
(b) train workers in the safe work procedures; and
(c) ensure that workers comply with the safe work procedures.
16.2(2) The safe work procedures must include practices and procedures dealing
with the lockout of machines used in the workplace.
Duty to inform workers
16.3 An employer must ensure that a worker is
(a) informed of any risks associated with a machine or tool used in the workplace; and
(b) provided with information, instruction and training in the safe use and operation of the machine or tool.


LOCKOUT

Locking out - safety precautions
16.14(1) Subject to subsections (3) and (4), when a machine is serviced, repaired,
tested, cleaned, maintained or adjusted, an employer must ensure that no worker
performs work on the machine until it has come to a complete stop and the worker
performing work on the machine has
(a) locked out the machine and removed and rendered safe any hazardous
condition; or
(b) otherwise rendered the machine inoperative in a manner that prevents
reactivation and provides protection that is equal to, or greater than, the protection
provided by clause (a).

16.14(2) An employer must ensure that a worker does not perform work on a machine
that is to be serviced, repaired, tested, cleaned, maintained or adjusted until
(a) the machine is tested to ensure that it is inoperative; and
(b) the worker is assured that it is inoperative.

16.14(3) An employer must develop and implement safe work procedures for the
service, repair, testing, cleaning, maintenance or adjustment of a machine when
(a) the manufacturer's specifications require the machine to remain operative
when it is serviced, repaired, tested, cleaned, maintained or adjusted; or
(b) there are no manufacturer's specifications and it is not reasonably practicable
to lockout the machinery when it is serviced, repaired, tested, cleaned, maintained
or adjusted.

16.14(4) When it is not reasonably practicable to lockout the machinery when it is
serviced, repaired, tested, cleaned, maintained or adjusted, an employer must ensure
that the safe work procedures developed in subsection (3) offer protection to a worker
that is equal to or greater than the protection provided by a lockout procedure.

Removing a lock
16.15(1) No person may remove a lock from locked out machinery unless the person
is the worker who installed the lock.

16.15(2) Despite subsection (1), a competent person designated by the employer may
remove the lock in an emergency or when the worker who installed the lock is not
available.

16.15(3) An employer must ensure that no worker returns a machine to operation after
it has been locked out or rendered inoperable until the worker determines that no other
person may be endangered by the operation of the machine.

Lock and key process
16.16(1) When the lockout procedure uses a lock and key, an employer must
(a) issue to each worker who is required or permitted to work on a machine a lock
that is operable only by that worker's key or a duplicate key;
(b) designate a worker to keep the duplicate key;
(c) ensure that the duplicate key is accessible only to the designated worker;
(d) ensure that the lock used has a unique mark or identification tag on it that
identifies the worker to whom the lock is assigned; and
(e) ensure that a logbook is kept to record the use of the duplicate key.

16.16(2) Where it is not reasonably practicable to use a worker's key to remove a lock,
the employer may permit the designated worker to remove the lock if the designated
worker has determined that
(a) the key used to lock the lock is not available; and
(b) it is safe to remove the lock and activate the machine.

16.16(3) When the lock has been removed, an employer must ensure that the worker
who locked out the machine is informed of the removal of the lock.

Control of more than one machine
16.17 When a central automated system controls more than one machine, an
employer must ensure that any machine to be serviced, repaired, tested, cleaned,
maintained or adjusted is isolated from the central system before the lockout
procedures are implemented.

Transitional: continued use of tag-out system
16.18 Despite the requirements of this Part, an employer may continue to use a
tag-out system at a workplace for no more than one year after this regulation comes into
force if a tag-out system was in use at the workplace when this regulation comes into
force.


ADDITIONAL SAFEGUARDS
FOR CONVEYORS

Emergency stopping system for conveyor
16.19(1) An employer must ensure that a conveyor has an emergency stopping
system that is readily accessible to workers working at the conveyor unless worker
access to the conveyor is prevented by guarding or other means.

16.19(2) An employer must ensure that a conveyor emergency stopping system is
designed and installed so that manual resetting is required before the conveyor can be
restarted after an emergency stop.

16.19(3) An employer must ensure that a conveyor cannot be restarted after an
emergency stop until an inspection has determined that the conveyor can be operated
safely.

Emergency pull-cords
16.20 When the emergency stopping system uses emergency stop pull-cords, an
employer must ensure that
(a) the pull-cords are clearly visible and readily accessible at the operator's normal
control station and at other appropriate points; and
(b) the system is activated when
(i) the pull-cord is pulled in any direction,
(ii) the pull-cord breaks, or
(iii) the failure of a single spring in the pull-cord assembly occurs.

Elevated conveyors
16.21 If an elevated conveyor crosses over a place where a worker may pass or work, an employer must ensure that a suitable guarding system is provided to prevent materials on the conveyor from falling on the worker.
