Abstract

A protected shaft conveying piped flammable gas should be ventilated direct to the outside air, by ventilation openings at high and low level in the shaft.
Any extension of the storey floor into the protected shaft should not compromise the free movement of air throughout the entire length of the shaft.
Guidance on shafts conveying piped flammable gas, including the size of ventilation openings, is given in BS 8313.
