EAST HANOVER, N.J. — Following the attack on New York City's World Trade Center, six trucks loaded with light towers departed the Ingersoll-Rand Equipment Store here, with a police escort to aide in the rescue effort. IR employees then worked into the night preparing four more truckloads of light towers for delivery.

The company has supplied more than 60 light towers to emergency management personnel in New York and also is coordinating the delivery of power generators and air compressors to relief efforts. Additionally, the IR Equipment Store in Elkridge, Md., and a dealer, Washington Air, worked together to provide light towers and air compressors to emergency management personnel at the Pentagon.
