IQ3 Water Mist Questionnaire – Closed Heads

IQ3 is part of a series of questionnaires designed to elicit the technical information required to underpin a satisfactory fire protection system design.  


In this document ‘Building Compartment Protection – Systems incorporating thermally actuated closed heads’ refers to installations protecting building compartments to their boundaries with closed-head thermally actuated ‘bulbed’ spray heads arranged to protect the compartment in its entirety. Systems using ‘zoning’ within compartments are excluded.
