Electrical Safety

Ensuring the safety of the wider electrical industry.

No matter which industry you operate in, our Electrical Safety team has the experience, knowledge and technologies to ensure that your employees are well-protected and that your Electrical Safety obligations are met. 

Mitton ElectroNet is well-known for our earthing systems design and testing capabilities, and is proud of our longstanding reputation for excellence. This expertise continues through our range of Electrical Safety services. We can assess existing infrastructure, provide hazard management advice and modelling, and manage the refurbishment or upgrade of your existing system.

Our Electrical Safety team is involved in almost every Mitton ElectroNet project; safety is an integral part of the work we do and we are proud to support Australasian businesses in meeting the highest safety standards. We enjoy getting out in the field and meeting our clients and we are often found on site, carrying out condition assessments as part of the design process, or testing prior to livening.
