Hidden Functionality Restored

PEME - Calvin Whittle & Gavin Stacey

Calvin Whittle and Gavin Stacey have been jointly awarded a safety award from one of our Asset Care partners.  The award is in recognition of their actions in identifying actual and potential failure modes that could have resulted in significant safety consequences, raising a Near Miss and their prompt intervention to ensure no further damage was experienced.

The failure modes related to emergency stops; whose functionality is not required during normal operation but they are critical in an emergency situation as their operation can mitigate failure consequences or they can fail prematurely, during normal operation, resulting in a loss of production. Neither scenario is desirable.

Whilst replacing an asset control system, which included the installation of cabling through multiple floors, Gavin and Calvin observed the following two issues:

  • The operating head was missing from an emergency stop, which meant the machine could not be stopped in the event of an accident or fault condition.
  • On a separate asset, they noticed a conduit was unsupported and resting on the emergency stop cabling. Damage to this cabling could result in a short and the machine could either potentially shut-down or in other circumstances,  the short could bypass the emergency stop, meaning that the emergency stop button could be operated and not work.

They immediately raised a Near Miss Report and installed a temporary ‘saddle’ to support and prevent damage to the emergency stop circuit cabling.

The picture shows Calvin and Gavin with their awards.

PEME Operations Manager, Alan Finnie, said “Calvin and Gavin are first-rate electricians and excellent practitioners of the PEME-way; which involves being vigilant when conducting maintenance tasking to spot degradation and faults and reporting them, even if the problems are not directly related to the tasking that we are responsible for. We stress the importance of recognising the potential end-effects of found failure modes and where significant, taking prompt action to report and remove risk.”
