The library includes pre-developed messages for 23 different hazards, across three phases of the disaster lifecycle (Preparedness, Response, Recovery), for three different channels (Twitter, Facebook, and Instagram).

Also featured are pre-developed messages for two broad subgroups of at-risk populations (people with physical disabilities and people with communication difficulties) across five basic disaster scenarios (Emergency Planning, Evacuation, Shelter In Place, Power Outage, and Disease Outbreak).

Some messages may be used without significant modifications, but because every emergency and its impact on public health is unique, some will serve as points of departure for users who communicate via social media platforms during disasters.

Messages are organized for easy viewing by hazard and, within each hazard, by phase of emergency response.

The messages were reviewed by individuals with expertise in content areas and in public information and risk communication from the following organizations:

• Centers for Disease Control and Prevention, Radiation Studies Branch
• National Public Health Information Coalition (NPHIC)
• Association of State and Territorial Health Officials (ASTHO)
