Portable earthing equipment plays a critical role in protecting electrical workers. However, long-term safety depends on more than good design and manufacturing. Inspection, maintenance and correct assembly are equally important in ensuring equipment remains fit for service throughout its working life.
A recent industry incident served as a useful reminder of this principle. In response, Betacom Earthing issued guidance encouraging asset owners and contractors to follow their established procedures for the inspection and maintenance of portable earthing equipment before use.
Portable earthing equipment is often regarded as a passive safety device. It may spend long periods in storage and then be called upon at a critical moment to perform as intended. For that reason, pre-use inspections are an essential part of any safe system of work.
Inspection should include checking for:
Our investigation into the recent incident found that personnel had reassembled the equipment in a manner that the manufacturer had not authorised. That reassembly contributed to the subsequent failure of the assembly.
While the circumstances were specific to that particular unit, the lessons are broadly applicable across the industry.
Personnel should assemble, repair and modify portable earthing equipment only in accordance with the manufacturer’s documented procedures.
What appears to be a minor change in assembly can affect the mechanical integrity of the equipment. Anyone carrying out maintenance or repair work should have access to current procedures and understand the importance of following them.
Pre-use inspection provides one of the simplest and most effective ways to identify potential issues before equipment enters service.
A thorough visual check takes only a few moments, yet it can reveal damage, missing components, wear or signs of previous unauthorised work. These inspections play an important role in maintaining confidence that equipment remains fit for purpose.
Manufacturers, asset owners, service providers and field personnel all contribute to the long-term integrity of portable earthing equipment.
Good design and quality manufacturing establish the foundation, but organisations must also support that foundation through proper storage, routine inspection, correct maintenance and adherence to approved procedures.
When every part of that process works together, portable earthing equipment remains ready to perform when it is needed most.
