General Fire Safety provisions inspection at Sellafield

Executive summary

Purpose of intervention

The purpose of this Intervention was to confirm that the General Fire Safety provisions on Site are adequate and to confirm compliance with the requirements of the Regulatory Reform (Fire Safety) Order 2005 is being achieved. BXXX is occupied by a relatively small number of people and is generally used for supplying various utility services to site. The fire risk assessment is current and indicates that a two yearly review period would be adequate for the building. No major issues were identified within the risk assessment, or from this intervention. In my judgement the Fire Safety provisions are reasonable although there are some improvements to be made.

I would assess this intervention as being adequate (GREEN).

Interventions Carried Out by ONR

I had access throughout the day to senior managers and subject area experts to provide evidence of compliance with the Regulatory Reform (Fire Safety) Order 2005 and the adequacy of their fire safety management arrangements through presentation of pre-prepared material and responding to questions. I challenged managers' statements and questioned personnel to test effectiveness and knowledge of arrangements.

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable this was not a safety systems inspection

Key Findings, Inspector's Opinions and Reasons for Judgements Made

The building is relatively modern in its construction; the fire safety design is based around compartmentation, active system actuation and early fire detection. I explored issues including servicing and maintenance regimes as well as future obsolescence of systems. There appears to be good vision of the state of the existing fire systems although it was agreed that a review of asset care would result in a better understanding of the state of the health of the various systems.

The Building Manager is experienced and has a positive attitude towards maintaining and improving Fire Safety standards within the building.

The lightning protection system has been identified as requiring servicing and testing and although this had been previously identified the work package is still to be actioned.

There is a foam pourer system provided as an active firefighting system for the oil storage tanks on the mezzanine level. The system requires testing and proving that it will provide the required standard of protection. The existing dry riser signage provided is to be replaced with ‘Foam Pourer-Mezzanine oil tanks' or similar, to ensure that crews are aware of what the system protects and that foam should be used not water.

Generally I felt that the importance of Fire Safety was understood, and there was a good level of knowledge displayed in regard to the various systems but in Fire Safety in general.

Conclusion of Intervention

There are no major issues that require formal regulatory action to be taken, I observed a good level of Fire Safety however there are a number of minor issues that when addressed would improve the current site arrangements; an action plan was requested by the 21 September 2016 to confirm how site propose to progress each point detailed, I will continue to liaise with the Building Manager to confirm that they are resolved in a timely fashion.
