Can anyone help with the EN/BS and other standards for flammable liquids cabinets. An insurer has said ours must provide two hour fire resistance. The only thing we can find with this level of resistance are safes.

I know of a company ( Walter Page - Safeways Ltd) who supply a fire cabinet with a 90 minute fire rating. Manufactured to DIN 12925-1. These are CE marked T.U.V/GS/DIN12-925-1 TRbF20ANNEXL. The
Website is www,walterpage.co.uk
Hope that helps?

I agree, the BS EN 14470-1: 2004 does not go up to a two hour rating - the maximum in it is 90 minutes.
I don't know of another standard, but no doubt if there is one someone else will tell us!

Hi Robert
Firstly the DIN standard mentioned was withdrawn earlier this year in Germany and replaced by BS EN 14470-1.
In terms of fire resistance there is a practical major diffrence between the two standards in terms of the internal cabinet temperature in an independent fire test. The BS EN cabinets with 90 minutes fire resistance take 90 minutes minimum for the internal temperature to excede 180 degrees Celsius. The DIN style cabinet takes less than 10 minutes. Single skinned cabinets according to BS 476 claiming 30 minutes fire resistance take less than 2 minutes. Another part of the BS EN standard is that hot vapours will not escape.
With standard solvents such as acetone, ethanol, diethyl ether etc I leave it to you to decide which cabinet is the safer.

I do not know the answer to your question but I have always relied on FM(Factory Mutual) approved flammable cabinets.
I believe they are a major insurer in the US with a long history in fire protection.
kind regards
Jeff
