Fire fighter deaths from tanker truck rollovers.

Mobile water supply vehicles, known as tankers or tenders, are widely used to transport water to areas beyond a water supply system or where the water supply is inadequate. Incidents in­ volving motor vehicles account for approximately 20% of U.S. fire fighter deaths each year; cases involving tankers are the most prevalent of these motor vehicle incidents. During 1977–1999, 73 deaths occurred in 63 crashes involving tankers. Of those deaths, 54 occurred in 49 crashes in which tankers rolled over (no collision), and 8 occurred in 6 crashes in which the tankers left the road (no collision). The other cases involved collision with another vehicle (10 deaths in 7 crashes) and colli­ sion with stationary object(s) (1 death) [NFPA 2000].
