Recommendations say that all stair nosings should be distinguishable through contrasting brightness. Absolutely not. To remain compliant with AS1428.1 the luminous contrast strip cannot be situated further than 15mm back from the front edge of the tread so any glow feature should sit either immediately in front of or immediately behind the contrast strip while retaining the contrast strip width between 50mm and 75mm. The related details of approved Document M are outlined below, together with the Treads recommendation. Learn More . The body of the stair nosing, so long as it is clearly differentiated from the luminance contrast strip, can extend to any depth on the riser. Nosings shall project no more than 1-1/2 in (38 mm). The risk is most hazardous at the head of a flight of steps when a person is descending.". The strip needs a luminance contrast of at least 30% with respect to the background material. The strip may be set back a maximum of 15mm from the front of the nosing. Visual contrast is not referenced into the IBC, so it only applies if the authority having jurisdiction has specifically incorporated the requirement into their set of codes. Continuous depth across the full width of every tread/going. High Visual DDA Compliant Design. By co-locating staircases with step-free routes, those who do not wish to, or cannot, use the staircase have an alternative option nearby. This strip must be between 50 and 75mm wide, must run across the full width of travel. Our specialty is in high performance, high-quality anti-slip solutions integrated with cutting edge glow in the dark pedestrian egress systems. These profiles provide a 55mm contrasting colour band on the nose and rise of steps and are available in both slim gauge and heavy gauge formats to accommodate all floorcovering types. Carborundum Modified Safety Stair Nosings. The luminance contrast strip must be between 50mm and 75mm wide and cannot be set back from the tread/riser. Other considerations, such as step size and type, should be taken when choosing a nosing. The documents indicate that there should be at least 30 points difference between the Stair Nosing LRV and that of the floor covering, e.g. At the nosing, each tread shall have a strip not less than 50 mm and not more than 75 mm deep across the full width of the path of travel. Colour requirements of stair nosing. Our products improve safety and government standards compliance at competitive prices. When located at the front of a stair nosing, the luminance contrast strip cannot extend down the riser more than 10mm. A luminance contrast strip that provides a strong visual clue of the tread/riser intersection must be included. The regulations state that a stepped access will satisfy requirement M1 or M2 if all nosings are made apparent by means of a permanently contrasting material 55mm wide on both the tread and the riser. There are two types of nosing available: 1) GRP nosings (made completely from GRP and gritted on the vertical and horizontal edges) 2) Equality Act (2010) compliant nosings. This states that stairs should have a 55mm x 5mm colour contrasting nosing edge. Our DDA compliant non slip treads meet this requirement and also adhere to the DDA requirements, and are made to measure to suit individual requirements. These contrasting nosing steps are highly durable due to the hard-wearing surface that they are manufactured with. 4.9.3 Nosings. A stair nosing is permitted to fold tightly down the front of the stair riser after forming a sharp intersection at the tread/riser intersection, but the stair nosing should not extend outward or form an overhang at the front of the tread. NCS Colour Centre is licensed to use the international colour system (ICS), enabling clear communication and accurate measurement of colour. The AS 1428.1 Standard prefers the strip to be one unbroken width, between 50mm and 75mm wide to maximize the contrast effect. Stair nosings are not allowed to project beyond the face of the riser. The change in level can be clearly highlighted with a nosing that contrasts with the surrounding tread and riser materials. The strip must measure two inches wide while remaining parallel to the nosing of each step and must possess anti-slip features. As an example, a 50mm strip may be presented as two 25mm strips with a very thin division between but not presented as five 10mm strips with bold divisions between. The luminance contrast strip must be between 50mm and 75mm wide and cannot be set back from the tread/riser. Stair edgings are used to define the edges of steps in line with guidelines in Approved Document M (ADM) of the Building Regulations 2010 and BS 8300-2:2018. However, extending the nosing too far, which was sometimes done on excessively steep stairs of old houses, creates a protrusion that is a trip hazard when ascending or descending the stairs. We are 100% Australian owned and operated with manufacturing/exporting facilities in Northern NSW. Also, according to ADASAD Advisory 504.4 Tread Surface, the contrasting color is not required, but strongly suggested. It cannot be set back from the nosing more than 15mm. In addition to these requirements, the tread must be placed no further than one inch from the nosing of the step. The body of the stair nosing can extend any distance down the riser. Steps with contrasting colour markings are an essential health and safety requirement for any commercial project and our Mayfair Flags with Contrasting Nosing are an ideal solution. When located at the front of a stair nosing, the luminance contrast strip cannot extend down the riser more than 10 mm One of the key requirements that designers and architects need to be aware of is the need for a 'luminance contrast strip' that provides a strong visual cue of the tread / riser intersection. Contrasting strips required between 50mm and 75mm in depth, extending across the full width of each stair nosing with a minimum luminance contrast of 30% to the background in accordance with AS1428.1, Clauses 11.1(f) & 11.1(g). "All nosings are made apparent by means of a permanently contrasting material 55mm wide on both the tread and riser.". This Standard sets out minimum design requirements to provide access for most people with disabilities and addresses a wide range of building design elements. The strip must have a minimum luminance contrast of 30% to the background (i.e. Luminance contrast is defined in Standard 1428.1 as the light reflected from one surface or component, compared to the light reflected from another surface or component. When located at the front of a stair nosing, the luminance contrast strip cannot extend down the riser more than 10mm. This statutory requirement refers to reasonable provisions and is intended to apply in normal conditions where the stair is illuminated by natural or artificial light and not in emergency situations such as a fire. Every colour has a Light Reflectance Value (LRV) of between 0 (Black) and 100 (White). If the nosing does protrude, it should be by no more than 25 mm.

MBSBUILDINGSCIENCESERIES120 GuidelinesforStairSafety,A i^U.120 1979 L.L ARTMENTOFCOMMERCENATIONALBUREAUOFSTANDARDS *<">tAU0* Luminance contrast is preferred to colour contrast as it highlights the difference in the light/dark qualities of two adjoining surfaces rather than just their colours. The colour variant should be at least 30 points (where black to white is 100 points) on all treads. Risers shall be sloped or the underside of the nosing shall have an angle not less than 60 degrees from the horizontal. Below are examples of non AS 1428.1 compliant stairs, not achieving the required minimum 30% luminance contrast or minimum strip dimensions and also not meeting anti-slip requirements: Two (or more) continuous steps would be considered a stairway and will trigger AS1428.1 requirements for TGSIs, handrails, and stair nosing.
