Part 15 Managing the Control of Hazardous Energy

Section 215.1 Securing by complex group control

(1) If it is not reasonably practicable to secure energy-isolating devices in accordance with sections 214 or 215 because of

(a) the physical size and extent of the machinery, equipment, piping, pipeline, or process system,

(b) the relative inaccessibility of the energy-isolating devices,

(c) the number of workers involved in the work requiring hazardous energy control,

(d) the number of energy-isolating devices involved,

(e) the extended length of time of the required isolation, or

(f) the interdependence and interrelationship of the components in the system or between different systems,

an employer may use a complex group control process approved by a Director of Inspection.

(2) Prior to initiating a complex group control process, an employer must complete a hazard assessment to identify the type and location of hazardous energy sources.

(3) If using a complex group control process, an employer must ensure that

(a) procedures are implemented to ensure continuous safe performance of the work requiring isolation of hazardous energy,

(b) a work permit or master tag procedure is implemented so that

(i) each involved worker personally signs on the job before commencing the work and signs off the job upon completing the work, or

(ii) a crew leader signs on and off the job for a crew or team of workers,

(c) a worker designated by the employer

(i) has activated all required energy-isolating devices to control hazardous energy in accordance with section 212(1), and

(ii) has secured the energy-isolating devices, and

(d) another worker designated by the employer has verified that all sources of hazardous energy are effectively isolated.

(4) If a complex group control process is being used and provided that the isolation point is reasonably accessible and the isolation required for work to be undertaken directly by the worker, each involved worker may place personal locks on the energy-isolating devices and verify effective isolation.

(5) Upon completing the work requiring isolation of hazardous energy, an employer must ensure that the machinery, equipment, piping, pipeline or process system is returned to operation in accordance with section 215.3.
