Study Notes
Supervising Electrical Workers
- To determine the appropriate amount of supervision for an electrical worker, the supervising electrical worker must consider all relevant factors, including, but not limited to, the type of work being done, the knowledge and skills of the employee, and the competence of the supervising electrical worker.
- The type of work can vary widely, such as residential, commercial, or mining, and each type of work presents different risks. Supervising electrical workers must assess these risks when determining safety requirements and the level of supervision required.
- When assessing the knowledge and skills of the electrical worker, the supervising electrical worker must use both academic and on-the-job training records.
Danger Tags
- Danger tags are used to warn all persons that equipment must not be operated as it may be dangerous.
- They must be attached in a prominent position at each isolation point.
- Only the person who signed the tag can fit and remove it.
- All persons involved in the electrical work must fit their own danger tag at the same isolation point.
- The tag should be removed upon completion of the work or at the end of the shift.
Safe Work Method Statement
- The identified risks and control measures must be documented in a written safe work method statement, and a record must be kept for at least two years after the work is completed.
- The work must be undertaken only in accordance with the pre-determined work method.
- The work must be undertaken only by competent persons who have the necessary tools, equipment, and personal protective equipment (PPE) for the work.
Working Near Energised Electrical Equipment
- A risk assessment must be performed by a competent person to determine the risk level associated with working near energised electrical equipment.
- Appropriate risk control measures must be implemented and documented in the safe work method statement.
Working in Roof Spaces
- The Occupational Safety and Health (OSH) Regulations generally prohibit workers from entering the roof space of buildings unless the electrical installation is de-energised.
- However, persons licensed to carry out electrical installing work may enter a roof space without de-energising the electrical installation provided a risk assessment has been performed and appropriate risk control measures have been documented in a safe work method statement and implemented.
Basic PPE
- Safety footwear must be non-conductive and comply with technical standard AS/NZS 2210.
- Safety glasses must have non-conductive frames and comply with AS/NZS 1337.
- Work gloves must have no conductive fasteners such as zips or studs and be made of durable material appropriate for the required work.
- Work gloves must comply with technical standard AS/NZS 2161.
- Safety helmets must be non-conductive and comply with AS/NZS 1801.
- RCDs (Residual Current Devices) on fixed or portable socket outlets provide additional protection against electrocution.
- RCD protection must be provided in the workplace as required by Regulation 3.60 of the OSH Regulations and technical standard AS/NZS 3012, Electrical installations – Construction and demolition sites.
Protective Clothing
- Many work sites require full body cover protective clothing to be worn at all times.
- Protective clothing should cover the body completely, be of material with properties equivalent to 185gsm 100 per cent cotton drill or better, have non-conductive and concealed buttons, have sleeves to wrist length, and have legs reaching to the footwear.
- Additional care should be taken to ensure clothing is reasonably close fitting and remains fastened to avoid catching or entanglement.
Additional PPE
- For general work, other common types of PPE include hearing protection (such as earplugs or earmuffs) and respiratory protection (such as breathing masks).
- Additional PPE should be considered for electrical work, such as testing and fault-finding. This may include flame retardant clothing, insulated gloves, arc rated equipment, insulating covers/mats, low voltage (LV) rescue kit, safety harness.
Rescue and Resuscitation
- All electrical workers and their assistants should have current rescue and resuscitation skills.
- The recommended method of CPR (cardiopulmonary resuscitation) is that published by the Australian Resuscitation Council in their Guideline 8 – Cardiopulmonary Resuscitation.
- All electrical workers should regularly refresh their knowledge of CPR procedures (recommended annually).
- Further information and training in rescue and resuscitation procedures is available from recognized training providers.
