Dear Coroner, We write to you with reference to your Regulation 28 notice issued to us in respected of Mr. Kenneth Audsley's death. As a direct result of this we have as a business implanted a number of changes in our company's working practices in an effort to prevent an incident of this nature ever being repeated. We remain deeply shocked and saddened by the loss of our friend and colleague, Kenny, and wholly support the notion to inform the industry to prevent recurrence of such a tragedy. We are aware that our solicitor, , has contacted you with a list of third parties that we deal with within our daily duties to assist with this process. We would also like to take this opportunity to demonstrate changes we have made in support of the notice. Firstly, the company' s employees are now prohibited from removing the lid of any transformer which is suspected to have been energised without adequate oil in place. All staff dealing with transformers have been briefed on the risks posed by removing a transformer lid in such circumstances, and indeed have been instructed to stop this practice. Rather, in the event that a transformer is returned in a condition leading us to suspect that it may have been incorrectly energised without sufficient oil in place, then steps will be taken to deliver this back to the manufacturer, Winders, to undertake the necessary repairs. Winders were party to the Regulation 28 report issued and also assisted with the HSE' s investigation, and therefore are now also aware of the potential risks posed by Carbon Monoxide to be able to respond appropriately to this. Secondly, we have now attached stickers to all of our transformers as per your suggestion, providing a reminder to third-party operators not to energise transformers without first ensuring there is sufficient oil inside. Please see the images below. The notices have been placed in obvious locations on the transformers. The first pair of labels have been sighted on one of the transformer covers which an engineer will necessarily have to remove in order to fit a set of cables before the transformer can be operated . .

The second label has been placed next to the oil sight glass. This shows a further arrow to indicate the oil level. The user is instructed not to energise if the oil level is below that point. ~

Finally, we have amended the documentation that is sent to our customers for all hires. This documentation includes
• A test sheet showing the readings of the equipment at the point of hire. This confirms that the oil has been checked and it indicates that all pre hire checks have been done (copy enclosed).
• We will also enclose a copy of the International Standard referred to by in her testimony to yourself.
• A warning notice, indicating the potential presence of Carbon Monoxide, should the transformer be energised without sufficient oil inside. (Copy on the next page). We trust the aforementioned is sufficient action to satisfy the notice. However, if you believe there is more we can do then we welcome any further suggestions.
