- Required by BCA
The manifestation marking of glazing is now required on most public buildings where access is provided under DDA (Disability Discrimination Act).
The manifestation marking of glazing is necessary for critical locations where people in passages in and about the building might not be aware of the glazing and may collide with it. Critical locations include large uninterrupted areas of transparent glazing which form, or are part of, the internal or external walls and doors of premises.
Where safety manifestation is deemed necessary, it may take the form of broken or solid lines, dots, squares, patterns and company logos as long as they are clearly visible and positioned at an appropriate height. Two height levels are currently required, depending on the standard to which compliance is required - 900 - 1000mm above floor level is required under AS 1428; and between 700 - 1200mm above floor level complies with the broader scope of AS1288. Manifestation graphics are available in a range of tones and textures that simulate acid etching, sandblasting or solid colours and are laminated directly onto glazing.
