Dry / Wet Riser Signs
Dry Riser / Wet Riser signage is needed to correctly identify if the riser is a dry or wet riser and also highlight its location. This is important as Dry Risers and Wet Risers have opposite functions.
Wet risers already have the water contained and release when needed to suppress a fire, whilst dry risers have fire engine access which is within 18 metres.
