Unconfmed vapor cloud explosion UVCEs

Fire is more likely tlian an explosion where tliere is a loss of contaimiient of a flammable material from a railroad car, barge, ship tank, or from a pipeline. However, both unconfmed vapor cloud explosions (UVCES) and boiling liquid-e.xpanding vapor e.xplosions (BEEVES) can occur as a result of transport accidents, (see Section 7.5)...

Davenport has listed more tlian 60 major leaks of flammable materials, most, of which resulted in serious fires or unconfmed vapor cloud explosions (UVCEs)." Table 16.3.1 classifies tlie leaks by point of origin and shows that if transport containers are excluded, pipe failures accounted for more than lialf tlie accidents. The biggest cause of tliese failures lias been shown to be poor construction due to use of wrong specifications or failure to follow specifications established.
