Don’t take a chance, check it, it may be live.
Despite the rigorous process of safe isolation, other types of electrical hazards can still be present when working on electrical systems.

Our ‘STOP. No Check. No Contact!’ campaign focuses on raising awareness of the dangers of live metalwork, which should always be checked with suitable test equipment.

The danger of unexpectedly live metalwork - STOP. No Check. No Contact!

Despite the rigorous process of safe isolation, other types of electrical hazards can still be present when working on electrical systems.

Standard safe isolation processes do not include checks to prevent some potential injuries caused by coming into contact with unexpectedly live metal parts.

Martindale electric identifies these additional hazards and examines how best to mitigate the risks.

Checking for live metalwork - Stop. No Check. No Contact!

There are other hidden dangers that, even with a rigorous safe isolation process, can still be present. One issue is the injuries caused to engineers, contractors, electricians and other workers coming into contact with unexpectedly live metal parts.

In this video, Martindale’s Glenn Patullo demonstrates a live metal check using the VT7 single pole indicator on an AC system. The video shows checks being carried out on exposed metal parts and screws, as well as the enclosure itself.

86% of electrical professionals have experienced at least one electrical incident whilst working.

To better understand the challenges faced by electrical professionals today, Martindale Electric conducted research among those working across the electrical industry in the UK, exploring their real-world experiences.

Our latest article summarises the key results from the survey:

• Electrical incidents and near misses in the workplace – the true picture?
• Electrical incident reporting: are lessons being shared?
• Does ‘culture’ play a part in non-reporting?
• Safe isolation procedures in practice
• Encountering unexpectedly live metalwork
• What the findings mean for electrical safety in the workplace

We hope the findings provide useful insight and contribute to ongoing conversations around improving electrical safety.
