Introduction
This document describes the design and testing criteria for fire safety storage cabinets (also referred to
as “cabinets” in this document) to be used in rooms to store flammable liquids in closed containers at
normal room temperatures.
Primarily, this document covers the three major safety requirements for storage of flammable liquids,
which are:
a) minimizing the fire risk associated with the storage of flammable substances and protection of the
fire safety storage cabinet’s content in the event of fire for a known (tested) minimum length of time
(fire rating);
b) minimizing the amount of vapour released into the working environment;
c) retention of accidental spillage within the fire safety storage cabinet.
Testing of the fire safety storage cabinet (see a) above) under fire conditions is a normative part of this
document and the procedures and interpretation of the tests are described in detail.
The fire test (see a) above) provides three categories of fire protection ratings. In practice the degree of
fire protection/rating allows the user to select, depending on individual circumstances, a fire safety
storage cabinet which will allow sufficient time for personnel to leave, and fire fighters to enter the room
before it is likely to that the flammables stored turn a possible minor/extinguishable fire into an
uncontrollable one. The methods of achieving b) and c) above are sufficiently flexible to allow for
local/national needs.
Caution should be exercised when determining the appropriate cabinet fire rating when flammables
having auto-ignition temperatures below 200 °C and/or having high vapour pressures at room
temperature are involved. When such flammable materials are being stored, expert advice should be
sought. Reference is made to national regulations concerning flammable liquids.
