RIT stands for, Rapid Intervention Team. The only purpose of the RIT is firefighter rescue. There are a number of reasons a firefighter may need rescued, such as being lost, trapped, injured or out of air. The past three shifts we have been doing the Saint Albans Fire Department version of the Pittsburgh Drill. We did it with less than the specified team members. The specs call for a team of at least 4 and no more than 5. A time between 18 and 20 minutes is considered good. My three man team completed the rescue in 19:56 and the two man team made up of two brutes on my shift did it in about 15:30. By the way, that hole is 14.5" x 20".
