Use Various Notification Methods
Once it becomes clear that a SIP or evacuation action must be taken, the facility manager must be able to communicate the information to people with a variety of special needs, which includes but is not limited to disabilities. Each facility manager must determine the types of communication that will reach all the people in their facility.
Facilities that use emergency warning systems such as sirens or other audible alerts should provide people who are deaf or hard of hearing prompt notice of impending disaster. Combine visual and audible alerts to reach a greater audience that either method would by itself. Consider using telephone calls, auto-dialed TTY messages, text messages, emails and even direct room-to-room contact.
