Ensuring no one misses critical information—even in emergencies
[ Why Is This Needed? ]
Even a few seconds of delay in disaster information can put lives at risk.
Yet most emergency alerts today rely heavily on text messages or on-site audio announcements.
For people who use sign language as their primary language,
these formats can create serious information barriers.
SignTong Disaster Information was designed so that urgent alerts can be
understood immediately through sign language, without delay or confusion.
