[: en] The evacuation of a building can be unsuccessful when the occupants do not know the location of the emergency signs.
Only an 38% of people look for conventional emergency signage during the evacuation of an unknown building. This figure is due in part to the existence, in shopping malls or airports, of numerous commercial or informational signs that distract attention from evacuation signs. The fact that the occupants are directed following the person in front or to the exit they know can lead to congestion and serious problems during the course of the evacuation.
To improve the visibility of emergency exit signs, Eaton has created a new technology called Increased Affordance -Augmented Assistance-, that allows these to be illuminated as a flash or intermittently during the evacuation of a building, making them much more striking for occupants in emergency situations.
“The time spent evacuating a commercial building during an emergency can have a great impact on the safety of the occupants. Every second counts. By facilitating people's ability to identify exit signs, we allow them to respond more quickly and reach a safe place with the least delay »
Jean-Luc Scheer, Product Line Manager at Eaton.
Traditional evacuation in a building without technology Increased Affordance
During the evacuation of a building there is a situation of confusion and the occupants can consider the safest option to return to the entrance they already know. This behavior can lead to situations of congestion and crowding, which subsequently result in a slow evacuation. In summary, in a traditional evacuation we run several risks:
- The occupants can return to the place they entered the building
- Crowding can slow evacuation
- The occupants can waste time trying to locate the exit
- Evacuation is slow
Evacuation of a building with technology Increased Affordance
With normal operation, the luminaires offer excellent visibility thanks to a high luminance that exceeds the minimum requirements in most countries.
When technology is activated Increased Affordance the visibility of the emergency signals is even greater through the emission of pulsed light or in the form of a flash, always respecting the minimum luminance levels established by the industry.
In summary, Augmented Assistance technology has many advantages:
- Avoid congestion in escape routes
- Assists people with hearing difficulties
- Ensures that occupants understand the severity of the emergency
- It is totally reliable
