What is the health and safety file?

The file must contain information about the current project likely to be needed to ensure health and safety during any subsequent work, such as maintenance,
cleaning, refurbishment or demolition. When preparing the health and safety file, information on the following should be considered for inclusion:
(a) a brief description of the work carried out;
(b) any hazards that have not been eliminated through the design and construction processes, and how they have been addressed (eg surveys or other information concerning asbestos or contaminated land);
(c) key structural principles (eg bracing, sources of substantial stored energy – including pre- or post-tensioned members) and safe working loads for floors and roofs;
(d) hazardous materials used (eg lead paints and special coatings);
(e) information regarding the removal or dismantling of installed plant and equipment (eg any special arrangements for lifting such equipment);
(f) health and safety information about equipment provided for cleaning or
maintaining the structure;
(g) the nature, location and markings of significant services, including underground cables; gas supply equipment; fire-fighting services etc;
(h) information and as-built drawings of the building, its plant and equipment (eg the means of safe access to and from service voids and fire doors).
