Hi, We have a new internal raised gantry area with chemical blending tanks penetrating the floor, the building control inspector has indicated this is being regarded as a mezzanine and needs fire protection cladding underneath to give 30 minutes fire protection ( We have a sprinkler system under the platform). However, when compared to BS 5980-1: 2012 requirements there are some discrepancies due to the open nature of chemical plant access areas and pipe penetrations.

So question to chemical processors what standards are your internal access and working platforms constructed to, and level of fire risk assessment to justifiy your position.

Hi Stuart

First point - what is the norm may not be an appropriate benchmark for a modified building.

So it might be that lower standards might apply to existing plant within a building, on the basis of so called "grandfather rights", but these would not apply for a new installation or modification. 

May be time to go back to those who planned these changes to find out what was discussed at the outset of the project inclusive of what liaison there was with the Planners and Building Control.

Also this project was probably within the scope of "CDM" so perhaps time to see what information was provided by the Design Team and taken forward into deliverables inclusive of the Health and Safety File.

[Not the time for a detailed discussion of the application of CDM!]
