2) Scope

This document gives recommendations and guidance for the design of smoke and heat control systems for covered and enclosed loading bays and coach parks. It does not specifically cover ventilation of such spaces under normal daily ventilation conditions (For information on normal ventilation Approved document F shall be referred to). Guidance on the ventilation of fire fighting shafts is not covered in this document which is covered in other guidance documents. Natural and mechanical ventilation systems are addressed in the document, including the use of ducted and jet fan based systems. Guidance is given on the specification for ductwork and dampers and the use and specification of sprinkler systems intended to impede fire growth. Controls and power supplies to the ventilation system are covered and recommendations are given on the commissioning as well as maintenance of the ventilation systems. Guidance is given to the use of CFD modelling which is covered in more depth in a separate Smoke Control Association Guide dedicated to CFD modelling for car parks and loading bays. For the purpose of this document, it is assumed that vehicles powered by fuels other than diesel or petrol will have a fire load similar to vehicles fuelled by petrol or diesel. The guide is intended for use by system designers, regulators and operators of loading bays and coach parks.
