Type of HMO Locations Minimum Class(BS 476: Part 7:1971/1997)All HMOs including Stairways, hallways, Class 1hostelslandings, lobbies (ie allcirculation spaces)Hostels onlyRooms 4 sq m floorarea or moreClass 1Rooms less than 4 sq mfloor areaClass 3Table 1 - Minimum classification for rate of spread of flame permitted indifferent locationsNote: space dividers or other similar vertical surfaces which sub-divide roomsor common areas should also meet the above standard.Acceptable locations for commonly encountered materials/productsIt is clearly impossible to identify the classification of existing coverings on-sitein HMOs unless the trade name of the product can be traced. The table belowillustrates acceptable locations for materials and products commonlyencountered. Where the trade name of the product under consideration isknown or can be traced, the classification should be sought from themanufacturer. For new products/materials to be installed, the manufacturersshould be required to confirm the classification of their product and produce avalid test report if appropriate. The following table gives a general guide in allother cases.Multiple layers of gloss paintSurfaces may be found where multiple layers of gloss paint have beenapplied. These surfaces will not provide Class 1 under BS 476: Part 7:1971/1987/1997. Therefore it is recommended that the paint is removed fromlocations requiring a Class I classification. Proprietary products may beavailable which can cover the paint thereby providing a Class 1 surface.These should only be used subject to a satisfactory fire test report but are notrecommended for areas subject to heavy wear and tear.London Fire Safety Guidance for Houses in Multiple OccupationVersion 2: 06/06
