A national safety group says Text messaging, Twitter and social networking Web sites could help families stay in touch in the aftermath of a disaster.
The Safe America Foundation announced Tuesday a national campaign to train families about alternate ways of staying in touch if traditional communication methods were not working.
More than 200,000 people are expected to participate in drills of alternative emergency communication tools starting on Sept. 11 and lasting through mid-October. Some participants are individuals who pledged on the organization's Web site. Others are employees of companies such as United Parcel Service, Motorola and Office Depot that plan to hold safety drills and training sessions.
