“Audit” is a scary word, no matter what the context. Equipment audits, however, serve a number of essential purposes for your business. First and foremost, audits are a way to properly and accurately gauge how safe the equipment is. This is particularly important when the potential hazards affect not only property but human lives as well. In the case of electrical equipment, personnel may be shocked or burned — sometimes resulting in significant injury, or even death.
There is also the risk of fires or explosions causing potentially extensive damage to equipment, machinery, infrastructure, or the site itself. The dangers are compounded in facilities that handle flammable chemicals. For industries such as banking, telecommunications, and information technology, electrical damage in a server room or to important data could result in catastrophic business interruption losses.
That’s why it is absolutely necessary — and mandatory under the legislation in any event — to conduct electrical safety audits.
Consider the electrical safety audit akin to a loss prevention program. Apart from identifying potential safety issues and electrical hazards and what damage or harm can result, the electrical audits can help businesses:
- Keep upper management up to date on the status of the facility
- Inform recommendations for improving safety standards and minimising potential hazards
- Identify areas of risks of vulnerability, danger, harm, or accidents
- Reinforce safety measures or inform improvements to policy/standard operating procedure
- Ensure compliance with safety standards in AS/NZS 3760:2010 and other regulatory and industry requirements
Datatel electrical auditors are experienced, knowledgeable, properly accredited professionals who will painstakingly examine your electrical equipment, gather information, and give you the straight goods. We will advise you of any deficiencies, hazards, or improvements that need to be made for regulatory compliance, safety, and increased productivity.
WHAT IS LOOKED AT
An electrical audit consists of visual inspections, scanning, taking measurements in order to assess the condition of the circuit(s), potential overheating, and any other potential problems.
- Current, leakage current, earth resistance, and voltage of all the circuits are measured, and any abnormalities or deviations to the applicable standards are noted.
- The complete electrical system is examined floor by floor, section to section — all the way from the generation point or service line to the load points and final branch circuits — and any abnormalities or deviations to the applicable standards are noted.
- A trial run is conducted on the generator in manual/auto mode.
- All components undergo thermal scanning to look for any deficiencies.
- Temperatures are analysed, and any lapses are classified.
- Pictures are taken of all visible lapses.
- A detailed, certified investigation/audit report containing findings and recommendations is submitted.
Specifically, auditors will examine:
- Whether the operating controls are in good working order, secured, properly identified, and aligned per specification
- Obvious damage, defects, or modifications — not just to the particular piece of electrical equipment but also its connectors, plugs, or cord extension sockets, as well as accessories
- Covers, guards, and the like — to see if they are properly secured and working as intended by the manufacturer
- Discolouration, which may indicate that there has been or is exposure to chemicals, moisture, or excessive heat
- Effective anchoring of flexible cords to the equipment, plugs, connectors, and cord extension sockets
- Damage to flexible cords
- Whether vents, exhausts, and inlets are clear and unobstructed
- Integrity of the protective earth and insulation
- Whether the current rating of the plug matches the current rating of the electrical equipment
- Applicable logs, reports, and filings, as well as standard operating procedures and safety protocols
Note that with brand-new electrical equipment that is new to service, there are different requirements under the Test and Tag standard than for electrical equipment that has been in use.
