Audit
•Person conducting electrical work holds relevant licences.
All employees have current and up-to-date electrical safety inductions and training.
Trained and current first aid qualified person available during performance of electrical work.
Prior to any electrical work, a risk assessment is completed.
Is there a written and approved high voltage safety procedure.
Are all electricians qualified and tested to be competent.
Have all specialized Electrical training/license requirements been identified and appropriate training/qualifications current? (i.e Classify hazardous areas or Jurisdiction specific, restricted/non – restricted licenses)
Prior to commencing work on energised plant or equipment a test for dead check has been completed and the equipment is isolated and in a zero-energy state and recorded.
Where there is live work (eg Commissioning), it must be carried out under a permit to work.
Prior to commencing high voltage work a “high voltage access permit” has been completed.
Before commencing work the Contract Sponsor has obtained and approved copies of:
• Certificates of currency
• licenses
• Risk assessments/approval
Before commencing work the Contract Sponsor has ensured:
• Communications to site
• Inductions
• Permit to work
• Appropriate supervision is present for the duration of the work being undertaken
• Contractor performance is monitored and that deficiencies/failures are immediately rectified
On completion of work the Contract Sponsor has ensured:
• A formal sign-off process is in place for the completion of work or a contract review process is in place for regular contract works consistent with the Procurement Procedure. (For regular/on-going or long term contracts, those exceeding more than 12 months, a formal regular review of the said contracts must be in place referencing the records and documentation on the performance of the contracting firm and its employees.
All critical electrical equipment is identified and has programmed maintenance (PM’s) inspections and testing programs installed in the SAP system.
All critical electrical equipment has available current and accurate schematics.
A system for the upgrade and management of electrical drawings is in place.
Less critical electrical equipment has programmed maintenance (PM’s) inspections and testing programs installed in the SAP system.
PMs are quantitative– e.g, measure brush length and replace if less than 40 millimeters long.
Switchboards are secured (Board covering all wires) or locked (whilst no work is being done on the switchboard) and there is clear access to the switchboard.
Electrical Isolation points and electrical energy sources are clearly identified and labelled on plant/equipment.
A weekly electrical maintenance schedule is in place and key stakeholders, i.e. operations, are involved in development and approval of final plan.
The plan is communicated to key stakeholders.
Overhead power lines are highlighted in the traffic management plan.
All staff working near power lines have been briefed on specific task hazards present.
Any power line intersecting an identified roadway is sign posted in both directions of traffic flow 8m prior to intersecting point?
Powerlines situated adjacent to operating areas and potentially within 8m of extended stackers and mobile equipment have warning signs mounted on fence lines or closest potential contact point?
All circuits and powered equipment have RCD (Residual Current Device) protection.
RCD is within test date and has a test tag in place. RCD are used when using portable powered equipment
All portable electrical tools inspected and tagged by an electrician as per standard?
Only trained qualified HV electricians may gain access and work on HV equipment.
Access (gates, and devices to prevent climbing) to high voltage areas is prohibited when no work is being performed?
Has an HV permit been obtained prior to work on HV equipment and is this readily available?
Is a risk assessment conducted prior to commencement of HV work.
Suitable PPE, test instruments, earthing and operating equipment are provided and maintained for safely effecting high-voltage isolations and work.
Hazardous areas shall be designated ex-zones in line with standards and take into account at least the following:-
- the amount of dust/vapours produced
- the lower explosive limit of the generated dust/vapour
- the level of ventilation under all conditions
-the temperature class of the zone
Assessment have been conducted by an appropriately qualified party.
All Hazardous Zones have a verification dossier readily available for all persons required to enter and/or work in the area. This dossier needs to include at least:-
- all classification documents
- risk assessments
- equipment classification certificates
- inspection reports
- completed drawings
- Dossiers need to be audited by a suitably qualified party every 5 years.
If a dossier does not exist then a plan must be in place to ensure a completed dossier by end of 2017/2018.
Controls are in place to prevent the formation of combustible atmospheres and should include:
- Ventilation extraction system’s
- Maintenance records.
- Housekeeping cleaning schedules, inspections and corrective actions.
Excavation or structure penetration work is not commenced unless authorised by an excavation and wall penetration permit
Person appointed to approve excavation and wall penetration permit have ensured current plans reviewed specific identification of GPS Longitude/Latitude of the worksite location prior to approving a permit
Persons appointed to issue 'ground excavation permits' detail on the permit the safe guards that must be adhered
Relevant operators have been instructed regarding permit requirements prior to commencing work
All electrical safety Incidents, i.e. hazards, damage, near miss etc, are reported immediately and within 24 hours of occurrence entered into RIVO correctly.
Electrical safety hazards are assessed by qualified person and adequate controls in place to reduce risk of electrical shock until full rectification, i.e. exposed insulation by bird damage.
All employees at site aware of electrical safety Incidents and relative controls, i.e. discussed at toolbox talks.
