(5) A control system must be used to prevent automatic startup after a power interruption or low voltage occurrence, if automatic startup in such circumstances is likely to create a hazard to workers.
(6) A control system must, where practicable, be designed so that the controlled equipment does not create a hazard to workers if the system fails or is shut down.
(7) Equipment operated by a new or altered control system must not be used until the control system has been thoroughly checked and tested to verify that it will function in the intended manner.
(8) The employer must ensure there is up-to-date documentation which is readily available to affected workers describing the design, installation, operation and maintenance of a control system.
(9) Control system hardware must be protected from circumstances that could adversely affect the performance of the system including mechanical damage, vibration, extreme temperatures or humidity levels, high electromagnetic field levels, and power disturbances.
(10) Written safe work procedures must be developed for the use of equipment operated by a control system, including lockout procedures as required by this Regulation.
19.37 (1) The documentation provided for a programmable control system must include a copy of the control program that will allow the equipment to be reprogrammed if necessary to ensure the safe operation of the system.
(2) Only qualified and authorized persons may have access to the installed control system software.
19.38 Where practicable and required to prevent a hazard to workers, a control system must be designed so that during an automatic sequence

(b) the operator may, if safe, be allowed manual control of the equipment, and
(c) the sequence will abort when a protective timer completes its assigned time without an expected event occurring.
19.39 (1) The maximum distance from which the operator may control equipment operated by a remote control system must be specified by the manufacturer.
(2) Written safe work procedures must be established
(a) that specify the maximum distance from which the operator is allowed to remotely control the equipment, and
(b) to ensure that workers remain at a safe distance from remotely controlled moving parts, and any remotely controlled mobile machine.
19.40 A wireless remote control system must incorporate
(a) error checking to prevent the controlled equipment from responding to corrupt data, and
(b) identification coding methods to prevent a transmitter other than the designated transmitter from operating the equipment.
19.41 The employer must ensure that
(a) only certified workers trained in a course acceptable to the Board conduct electrofishing operations,
(b) workers are provided with a statement of their responsibilities and written safe work procedures, and
(c) workers are trained in and are knowledgeable of their responsibilities and work procedures.
19.43 (1) Repealed. [B.C. Reg. 312/2003, App. B, s. 35.]
