The Walter Reed Army Medical Center (WRAMC) in Washington, DC suffers a four-day power loss following an electrical transformer fire on August 27. Backup generators ensure patient care is minimally affected, but as a precaution 77 of the hospital’s roughly 100 patients are moved to other facilities until it regains full power. Most go to the National Naval Medical Center (NNMC) in Bethesda. According to Capt. Tom Sizemore, the acting commander of the NNMC, precautionary measures are necessary due to the size of the patient transfer. So on August 28 he sets the hospital into a mass casualty condition. Usually such a condition is only set in response to a major incident with many seriously injured people. Sizemore says, “This most unfortunate opportunity has provided NNMC with a very special opportunity. We were able to exercise our response system, with real patients, but (thank God) not with patients involved in some mass disaster.” [Stripe, 8/31/2001; Bethesda Journal, 9/6/2001; Stripe, 9/6/2001; Marble and Milhiser, 9/2004, pp. 146] Walter Reed is about six miles from the Pentagon, and its ambulance teams will respond to the attack there on September 11. Many believe that coping with the power failure helps prepare them for this. One member of staff later says, “A lot of the procedures that we used in the September 11 tragedy, we had just come out of this power loss where we had implemented a lot of what we did. We had good procedures in place that we had already just executed. It was really eerie.” [NurseWeek, 9/17/2001; Marble and Milhiser, 9/2004, pp. 145-146] A similar incident also occurs around this time at DeWitt Army Community Hospital at Fort Belvoir, an army base roughly 12 miles south of the Pentagon. The details of this are unspecified. [Stripe, 9/20/2001] Ambulance teams from DeWitt will also be involved in the emergency response to the Pentagon attack. [Marble and Milhiser, 9/2004, pp. i]
