U.S. Army Safety Center files for the years 1984-1991 were searched fo
r ground accidents involving sleeping soldiers. There were 68 incident
s which could be so categorized, 53 of which resulted in injuries and
15 in fatalities. The average cost to the Army, adjusted to 1991 dolla
rs, was $8,300 for each injury and $61,900 for each fatality. The inju
red required an average 24.6 days of lost duty time for recovery. The
incidents most commonly occurred when soldiers slept near vehicles and
less commonly when they slept in designated ''safe'' areas. With impr
oved guidance and training, such accidents could be reduced.
