Stored Energy

The risks associated with stored energy sources are to be identified, assessed and controlled in the Project Risk Register, in accordance with the hierarchy of controls.

All service locations where stored energy sources are present are to be identified and documented, with relevant disconnections or isolations put in place by appropriately trained persons

Information on the gas, chemical, fuel or refrigerant lines is to be obtained

Emergency procedures shall be established specific to the stored energy sources being managed.

All contractors must identify any High Risk activity within their scope of work, evidence of experience carrying out this activity, provision for full time supervision, relevant licenses and competencies of supervisor and workers

All contractors are required to develop and submit, a specific safe system of work, e.g. SWMS, for this High Risk activity to the Baseline site representative for approval (7days) prior to commencing works

This MUST include an Emergency Procedure / Rescue Plan, evidence that supervisors and workers are trained in the procedure

The Baseline expectation is that our contractors will follow all safety requirements listed within our standards

Note: Evidence of specific licence requirements e.g. LV rescue, HV Operator, Lock out Tag out and industry induction MUST be provided

Proposed methodology to be reviewed by Project Team and assess for need to conduct activity specific High Risk Workshop.

(If required) High Risk Workshop to be conducted with contractor undertaking activity and Baseline Project Team. Methodology, competencies and timing MUST be confirmed and agreed with all stakeholders

Prior to conducting isolations a Baseline isolation Permit MUST be submitted by the subcontractor supervisor and approved by the Baseline site manager.

Where complex isolations are being carried out a toolbox talk MUST be conducted by a Baseline Project Team member immediately prior to commencing works, and include all workers involved in the activity

Note: The Isolation Permit MUST be provided by the engaged subcontractor for Baseline approval, and photographic evidence of LOTO included in permit

Baseline site manager / supervisor MUST monitor the isolation / energisation activity until the work activity has been completed.

A Task Observation should be conducted by a Baseline Project Team member to record the works being carried out as per approved SWMS.

The Subcontractor Supervisor MUST confirm isolation is active and review periodically for the duration of the works, and submit a request to energise when required

At the end of the activity the subcontractor supervisor MUST confirm the work has been completed and the isolation can be removed from relevant equipment.

The Baseline site manager / supervisor MUST confirm the isolation has been completed and identify is the service is to be energised

An energisation permit will be required prior to the energisation of the relevant equipment.

Where possible stored energy sources shall be bled or depleted until empty prior to commencing works

Pressurised systems shall be depressurised and tested prior to commencing works

Work planning shall consider stored energy sources associated with products and plant.

Do not perform work on energised (live) equipment or parts. Unless undertaking testing, systems and equipment must be de-energised and be proven to have a zero-energy state and isolation points must be secure (locked and tagged) before work is performed on them

Access to keys for stored energy cabinets, plant rooms, powered plant and equipment are to be regulated and controlled

The properties of the stored energy are to be understood prior to commencing works, e.g. the nature of the gas or liquid, pressure levels when discharged, reactivity etc.

PPE used for electrical work must be flame-retardant and comply with relevant standards for anti-static, ARC 1 or 2 etc.

1. Complex isolations refer to locking out multiple isolation points with several locks and isolators working on the same item being isolated. Identify all stored energy sources and associated isolation points as a group

2. Appoint a main isolator (responsible to manage the lock box)

3. Place locks on isolated points with each personnels lock having individuals’ names

4. Test for dead with main isolator

5. Main isolator will be responsible for the lock box and keys. All keys will be placed into the lock box along with each isolators lock placed on the outside

6. Once the works have been completed and verified all personnel report to the main isolator to access the keys and a sign out process must occur

7. Finally, an energisation process must be completed
