Electrical shock testing transformers - 26 June 2020
A 24-year-old electrician received a potentially fatal electric shock while testing a transformer. He contacted exposed conductors as voltages were applied to the transformer.
His co-workers used an automatic external defibrillator (AED) device to revive the worker before he was taken to hospital.
Electrocution is the second leading cause of death in the construction industry.
Electrical work must be carried out by a licensed electrician, who has the necessary training, tools, equipment and experience for the task.
In NSW, it’s prohibited to work on live electrical equipment unless one or more exceptions apply.
The Code of practice for managing electrical risks in the workplace outlines when working live is permitted, and how to do it. Working de-energised eliminates significant electrical risks.
When voltages are applied to electrical equipment, or measured, make sure:
- no-one can accidentally make contact with exposed components
- a safe work method statement outlines the hazards, risks and control measures
- workers use tools, test equipment and PPE properly
- an emergency plan is prepared
