HAZARD NOTES 13 DEC 2018

Natural hazards, where risks are often high and lives and property are at stake, raise considerable uncertainty and anxiety. Providing the community with information that is designed to instil specific preparation and response behaviours is important for emergency services.

Hazard Note 57 investigates a body of research to determine whether well-established, theoretical principles could be applied effectively in warning messages for natural hazards. The research suggests that the following principles could maximise comprehension of warning messages:


Sponsor's message

  • be in an easy to understand layout – use dot points or subheads where possible
  • personalise risk
  • cover the hazard type, severity, likelihood, possible consequences, location and timeframe
  • be in plain English
  • group related information together
  • be issued by a credible source
  • link to other credible sources of information

Emergency service agencies continue to revise their messages, but preliminary tests in simulated settings suggest that community comprehension of emergency messages can be improved by using these principles.
