 What I would add is a public communications plan ahead of time so that you can communicate with people. One of the things you don't want is for people to start going into areas or buildings looking for you and you're not there because you're putting other people at risk. So being able to have cell phone numbers of individuals in your cell phone may not work depending on the hazard in terms of calling but you may be able to use the feature to do text messaging and that's very important to be able to send text messages to individuals. When I've been in situations where alarms have gone off in buildings and my team, whom I've prepared four or six people to help me evacuate from the building, that's one of the methods that we've used. And my team knows where to find me most of the time or where I may be but when I'm not there they need to communicate with each other and try to communicate with me so that no one's putting their themselves at risk but we're able to communicate with each other as best as possible to get out. So when I was in Washington DC and we had an earthquake, my assistant was out of the building and somehow she was able to find her way back into the building and I was on the eighth floor but my team communicated with each other and were able to assist me out of the building and another time when there was actual fire in the parking garage and the alarm went off I was outside I wasn't in my office but some of my team were there so they went and looked to see where I would be and then they communicated with each other, sent two people downstairs to see if maybe I had not perhaps come into the building at that point and sure enough they found me outside and were able to communicate with each other via cell phone and text and everyone was able to get out of the building safely.
