These include finding employment, availing services, and having access to education. Through this law, people with disabilities should have the same opportunities as everyone else. Learning disabilities, physical disfigurement, and the presence of diseases in the body such as HIV are also classified as disabilities. As defined by the DDA, disabilities are those that affect a person’s physical, intellectual, psychiatric, sensory, and neurological capabilities. On landings to external stair flights, where tactile paving is used, the minimum length of landing should be 1.2m.Basically, this law makes it illegal to discriminate against people with disabilities. However where, on an intermediate landing, a change of direction of 90º or more occurs, the centreline length need not be measured if the effective width of the stair is maintained across the landing. The minimum length of a stair landing, measured on the centreline of travel, should be either 1.2m or the effective width of the stair, whichever is less. Have an effective width of not less than the effective width of the stair flight it serves, andīe clear of any door swing or other obstruction other than to a private stair as noted below. A single landing may be common to 2 or more flights, andīe level except, in external locations, for any minimal crossfall necessary to prevent standing water, and The most comfortable combination of rise and going varies between individuals but in general, a going in excess of the minimum, resulting in a figure in the upper end of the range in note 5 above, will increase both safety and amenity.īe provided at the top and bottom of every flight. The maximum rise and minimum going on a private stair should not be used together as this will result in a pitch greater than the recommended maximum.Ĭlause 4.2.10 should be referred to for exceptions where a private stair should meet the above recommendations for ‘any other stair’. For example, stairs provided with the minimum going of 250mm would result in rises of at least 150mm. The aggregate of the going and twice the rise should be at least 550mm and not more than 700mm. The going measured at the narrow end of a tapered tread should be at least 50mm (see diagram to clause 4.3.1). Where a flight consists partly of straight and partly of tapered treads, the going of the tapered treads should be uniform and should not be less than the going of the straight treads. In a straight flight, or in a part of a flight that is straight, measurement should be uniform along the centreline of the flight. Tapered tread means a stair tread in which the nosing is not parallel to the nosing of the tread or landing next above.Ĭonversions - in the case of conversions as specified in regulation 4, the building as converted shall meet the requirements of this standard in so far as is reasonably practicable, and in no case be worse than before the conversion (regulation 12, schedule 6).Īll rises in a flight should be of uniform height. It should not, however include any external stair that forms a part of an accessible route to the dwelling. This might include, for example, a stair from a dwelling to a private garden, or a stair providing access to or within a domestic garage. It may also apply to any stair within the curtilage of a single dwelling, which is not accessible to the public. Private stair means a stair wholly within a dwelling. The following terms are explained to provide clarity to their meaning in the Technical Handbooks. Design should also address the issue of appropriate guarding, where a level change is made, and seek to eliminate any possible trip hazards. Stairs and ramps should be constructed to be within limits recognised as offering safe and convenient passage and designed so that any person who is likely to use them can do so comfortably and safely, with the minimum amount of difficulty. This risk can be greatly reduced by ensuring that any change in level incorporates basic precautions to guard against accident and falls. Half of all accidents involving falls within and around buildings occur on stairways, with young children and elderly people being particularly at risk.
