Would People Hear, Understand and Act? An Assessment of a County Public Warning Plan Against Guidance on Warning, Risk Communication and Access

The Plan and the Standard

This assessment examines the public warning section of the course's composite metropolitan county emergency operations plan, as it would apply to a terrorism incident such as an attack at a large public event. The national preparedness goal defines public information and warning as a core capability common to all mission areas, which it describes in terms of timely, dependable and usable information that reaches everyone affected (U.S. Department of Homeland Security, 2015). The assessment judges the plan against that capability and against research on how people respond to warnings, and reports where the plan would leave people uninformed.

What the Plan Provides

The plan authorizes the public information officer and the emergency manager to issue warnings through the county's alert system, which sends text, email and voice messages to residents who register, and through federal alerting channels that reach mobile phones in an area without registration. Federal law provides for an integrated public alert and warning system that state and local authorities can use to send alerts through multiple channels (6 U.S.C. § 321o), and the county is approved to use it. The plan also lists the county's social media accounts and a media contact list, and it includes six prewritten message templates.

Would People Hear the Warning?

Reach is the plan's strength. Federal mobile alerts reach phones in the affected area without registration, which matters for visitors at a stadium who have not signed up for county alerts. The county alert system reaches registered residents through several channels. The gap is for people without mobile phones or who do not register, especially some older adults, and for people inside buildings where reception is poor. The plan does not describe sirens, door-to-door notification or coordination with venue public address systems, which would reach people inside a stadium faster than any phone.

Would They Understand It?

Research on public response to warnings has found that people are more likely to take protective action when messages are specific about the hazard, the location, what to do and when, are consistent across sources and come from a credible source, and when people can confirm the warning with others (Mileti & Peek, 2000). The county's six templates name the source and the hazard but are vague about location and action: one reads, avoid the downtown area until further notice. That tells people where not to go but not what to do if they are already there. Research on preparedness communication argues for emphasizing actions people can take rather than the risk itself (Wood et al., 2012), and the templates mostly do the reverse.

Would They Act on It?

Warnings prompt action more reliably when they are repeated and consistent across channels. The plan does not specify how often messages will be updated or how the county will keep messages consistent with those from the city police, the stadium operator and state agencies. In the composite county's past flood response, conflicting messages from several agencies drove calls and confusion; a terrorism incident, with more agencies and a faster pace, would be at greater risk. The plan's joint information center would address this, but it is staffed only for short events.

Would Everyone Be Reached? Access and Language

The capability calls for information to reach the whole community. The county's templates exist only in English. Census figures show roughly one county resident in seven using another language at home, and a stadium crowd would include many visitors. The plan does not describe how alerts would be made accessible to people who are deaf or hard of hearing, beyond text messages, or to people who are blind, beyond voice calls to registered numbers. It does not mention interpreters for televised briefings. People with limited English or disabilities would be the most likely to be left uninformed, and visitors unfamiliar with the downtown street grid would struggle with location-based instructions.

A Test Message

To show the difference, consider the county's current template for an incident near the stadium: avoid the downtown area until further notice. A version following warning research would name the source, the hazard, the location, the action and the time: county emergency management: police activity at the north entrance of the stadium. If you are inside, stay where you are and follow staff instructions. If you are outside, move away from the north entrance toward Fifth Street. Next update in 15 minutes. The rewritten message is longer, but every added phrase answers a question people would otherwise try to answer by calling 911 or searching social media, which slows their response and burdens responders.

Summary of Gaps

Table 1 summarizes the assessment.

Recommendations

Four changes follow from the gaps above. First, the county should agree with the stadium operator and other large venues on how venue public address systems will relay official warnings. It should rewrite its templates to state precise locations and specific actions, such as shelter where you are, stay away from the north entrance or follow staff to the east exits, following the emphasis on actionable information. It should set an update schedule and a procedure for coordinating messages with city, venue and state partners from the first alert. And it should translate its templates into the county's most common languages, add accessibility measures for deaf, hard of hearing and blind residents and arrange interpreters for briefings. None requires new technology; all require planning before the event.
