This document outlines fire risk evaluation and reduction levels for different construction phases from lowest to highest risk. It shows the basic risk levels for wet trades, building works, mechanical, electrical and plumbing first fixes, superstructure, and substructure work. It also lists added risks that increase the risk level like temporary or permanent fire and life safety systems, controlled versus uncontrolled floors, and removal of packing materials. Risk reduction factors are outlined but some like fire extinguishers alone are not seen as very effective.
