1. Get in front of the camera, surrounded by people, and send a reassuring message immediately. Put it on YouTube and Facebook. 2. Set up an event-specific website and Twitter hashtag to follow. Aggregate info from various key sources. 3. Stream updates constantly over a dedicated radio channel that people know about. 4. Establish an emergency people can call and text for automated updates. 5. Set up a number people can subscribe to for text updates. 6. Follow up with people when it is over and ask how they are. 7. Assess outreach tools afterward - which were most effective? Which not? 8. Ask employees for suggestions regarding improving crisis plans for the future. 9. Do something light to help people calm down - scale this appropriately for size and complexity of audience. 10. Post photos, messages, Tweets, etc. in an online archive so people can refer to it later. This has an operational use (after action review) as well as a human one (memory book). Good luck!
