What special considerations should be taken into account for hearing-impaired occupants?

Implementing visual alarms or notifications in addition to audio announcements is crucial for effectively communicating with hearing-impaired occupants. Since these individuals may not be able to hear alarm systems or audio messages, visual alerts, such as flashing lights or screens displaying important information, serve as an essential means of ensuring their safety and awareness in emergency situations. This approach not only helps to deliver the message clearly but also enables the hearing-impaired occupants to react appropriately during critical moments.

Other considerations like providing written notes, ensuring announcements are made slowly, or using interpreters can be beneficial, but they do not necessarily cover the immediate need for real-time alerts that visual notifications provide. Visual alarms are key for ensuring that hearing-impaired individuals are promptly informed about emergencies that require immediate action.
