SAFETY SIGNS & POSTERS

VIEWING DISTANCES

For a sign to be visible and understood

Viewing distances (according to BS ISO 3864-1: 2011) – Fire equipment and sign categories Viewing distances (according to BS 5499-4: 2013) – Escape route signs

The size of the sign is defined by the maximum viewing distance from which the sign is understandable. The viewing distance at which a sign of a particular size is conspicuous and comprehensible depends on the illumination of the sign and the amount of detail it contains.

The larger the sign the greater the viewing distance will be.

Signs for high and intermediate location level

Signs positioned at a the High Level Location are intended for all users of a building. Therefore, they shall be installed at a height above 1.8m. This way the presence of people or objects located between the equipment and the user does not obstruct the visibility of the signs. Signs located at the Intermediate Location Level are intended for the user of the identified equipment. This signage contains complementary information advising the correct usage of the equipment and should therefore be installed at a height of between 1.2 & 1.5m.
