Electrocution as a result of contact with exposed Low Voltage conductors, High Voltage conductors and contact with live conductive components
Arc flash as a result of uncontrolled release of electrical energy
Reduce employee exposure to electrocution through:
1. Safe design of electrical installations and apparatus as per relevant Australian Standards
2. Robust installations specifications as per BHP engineering specs and Australian standards
3. Appropriate protection systems installed and functional
3. Verify that employees authorised to conduct electrical work are trained, competent and familiarised with procedures, standards and safety/test equipment
4. Electrical operating areas secure and access managed
Electrical (L.V & H.V)
Protection systems are designed, installed, maintained and functional in accordance with legislative requirements, Australian Standards and BMA Engineering Standards
a) A protection study is conducted for all Electrical installations, ensuring settings meet site standards and AS
Have you inspected all new Electrical installations and verified protection settings as per design/AS?
b) There is a process in place to ensure that BMA GRM regularly tests the accuracy, condition and functionality of all protection devices as per AS
Have you located PM02 Electrical Statutory work orders scheduled for the week?
Have you verified the PM02 has been time confirmed?
Was the work performed by an authorised tester and a copy of the test results saved to the notification?
Have any defects had a subsequent notification raised?
Have you inspected a switchboard for circuit breakers with a test button?
Perform functional test by pushing button. ***Caution - when conducting test - verify circuit by name of c/b and inform any effected persons of intent to trip power (if not labelled report to EEM)***
What was the result?
Electrical Test Equipment & PPE is fit-for-purpose, in good condition and worn by electrical workers to prevent electrocution in accordance with SOP21 & Electrical Standard
a) Fit-for-purpose electrical test equipment & PPE is specified, acquired, available, inspected prior to use and worn as per SOP21 & Electrical Standard
b) Work management strategies are established for inspection, testing and maintenance of electrical test equipment & safety PPE.
Obtain the test equipment register or PPE register and select a sample.
Are work management PM02 strategies established and executed for inspection, testing and maintenance of electrical safety test equipment PPE?
c) Fit-for-purpose electrical test equipment & PPE is in use by employees
Select a sample of electrical tasks:
Are the required electrical safety test equipment & PPE in fit-for-purpose, good condition and in use by electrical workers. - e.g. Arc flash clothing, no metal jewellery, test meters are in use etc
Electrical switching is performed to a safe standard
Electrical work is performed to a safe standard
Work in the vicinity of Electrical installations is controlled
a) A task based risk assessment is performed for all electrical switching activities and work on switchboards
In field verification of work. Select a sample of electrical work or switching:
Was the work performed in accordance with SOP21 & Electrical Standard?
b) Switching activities are executed to an authorised switching programme
Inspect one electrical task:
Are isolations in place as per Isolation and tagging SOP and SOP21?
c) Access to Electrical operating areas is controlled
Perform in field check of substation access control:
Select a sample of electrical operating areas:
Are the areas locked and only accessible by authorised personnel?
Is there a key register in place?
Does a selected sample reconcile with the training matrix?
Uncontrolled Release of Electrical Energy
A. Hazard Assessment is carried out, controls are implemented and records kept.
Each Electrical operating area has a Hazard Risk Category sticker affixed
Take a sample of Electrical operating areas:
Is an Arc Flash Hazard Assessment in place?
Are there controls in place?
Are stickers in place?
Have any intolerable risks been addressed (Cat X)?
Are assessments readily available?
B. Electrical PPE is fit-for-purpose and worn by electrical workers and in line with HRC rating
Is electrical PPE provided and in serviceable condition?
Select a sample of Arc Flash PPE:
Is Arc Flash PPE compliant with SOP21 and the Electrical Standard?
Is Electrical Arc flash clothing being used in the field?
C. Are remote Switching and Operation systems implemented?
Inspect one task in a high risk arc flash installation:
Is remote switching being used (if installed)?
High Voltage Electrical
To ensure compliance with SOP30, interview a sample of employees and contractors via field observations (include non-electrical personnel and supervisors.
Do employees understand the requirements for working on or near electrical equipment?
Have risk assessments been performed?
Do employees hold relevant permits for high risk work?
Inspect recent requests to work near power lines:
Are controls in place?
To ensure HV switching and electrical work is performed in accordance with SOP21 & Electrical Standard (specifically performing HV switching activities):
Perform a record check and check a sample of switching programs, access permits and task based risk assessments for electrical work or switching activities:
Where the checks compliant?
Conduct an in field assessment of HV switching:
Was the assessment executed as per standards?
