Tiny details and dimensional limitations within the design are critical to ensuring that the stair is safe and compliant to relevant standards and regulations.  \nCERTIFICATED FIRE PROTECTED STAIR  \n4 © British Woodworking Federation 2017  \nScope of this document  \nThis guide is provided to assist stair designers, manufacturers and building professionals involved in the design and specification of domestic timber stairs for the UK market. It draws information from a range of standards and regulations impacting upon staircases. This guide covers stair specifications for basic flights and balustrade by providing advice on suitable sections, by reference to historical data, design tables, calculation or suitable test methods.  \nDesign and manufacture is only part of the delivery of effective staircases. Installation practices must also be adhered to as recommended by the staircase manufacturer and building designer (1) . The responsibility for ensuring that competent (2)  \ntradespeople install the product is that of the project manager and builder.  \nFurther information is provided in the BWF Stair Scheme Installation Guide:  \n[http://www.bwfstairscheme.org.uk/](http://www.bwfstairscheme.org.uk/)[ ](http://www.bwfstairscheme.org.uk/)[wp-content/uploads/2015/06/stair-](wp-content/uploads/2015/06/stair-)[installation-guide-web-ready-final11.pdf](installation-guide-web-ready-final11.pdf)  \n1 A designer is an organisation or individual that prepares or modifies a design for any part of a construction project. Designers include architects, consulting engineers, interiors designers, temporary work engineers, chartered surveyors, technicians, specifiers, principle contractors, specialist contractors and some tradespeople.
