Safety

Alarm system (sound/buzz signal)

The issue of safety is an important one for people who are deaf or hearing impaired.

People rely on sound to warn them of possible danger, warning bells, alarms sirens, horns, even shouts may be of no benefit to people who do not hear clearly. Depending on the individual's degree of hearing impairment, they may not be heard at all or, if heard, the person may not be able to locate the direction of the sound. Shouted warnings may be muffled and unclear adding to the hearing impaired person's feeling of panic and uncertainty in an emergency. As deaf and hearing impaired people rely on visual clues, an added problem in emergencies is the fact that visibility is often poor - due to electrical failure, smoke or other factors.

Buildings should include flashing light alarms to warn people of fire danger or the possible need to evacuate for other reasons. Exits should be clearly shown using flashing red lights.

Torches or alternative lighting should be readily available. Emergency and evacuation procedures should be clearly displayed on appropriate signage.
