Storage Facilities The Fhxborough disaster (Lees, 1980) occurred on June I, 1974, and involved a large, unconfined vapor cloud explosion (or explosions—there may have been two) and Fire that killed 28 people and injured 36 at the plant and many more in the surrounding area. The entire chemical plant was demolished and 1821 houses and 167 shops were damaged. [Pg.2306]

Any flammable liquid under pressure above its normal boiling point will behave like LFG. Liquefied flammable gases are merely the most common example of a flashing liquid. Most unconfined vapor cloud explosions, including the one at Flixborough (Section 2.4), have been due to leaks of such flashing liquids [2],... [Pg.165]

Davenport [1] has listed more than 60 major leaks of flammable materials, most of which resulted in serious fires or unconfined vapor cloud explosions. Table 9-1, derived from his data, classifies the leak by point of origin and shows that pipe failures accounted for half the failures— more than half if we exclude transport containers. It is therefore important to know why pipe failures occur. Following, a number of typical failures (or near failures) are discussed. These and other failures, summarized in References 2 and 3, show that by far the biggest single cause of pipe failures has been the failure of construction teams to follow instructions or to do well what was left to their discretion. The most effective way of reducing pipe failures is to ... [Pg.179]

Historically, this phenomenon was referred to as unconfined vapor cloud explosion, but, in general, the term unconfined is a misnomer. It is more accurate to call this type of explosion simply a vapor cloud explosion. ... [Pg.69]

Especially, for gaseous mixtures exploding in the open the term unconfined vapor cloud explosion (UVCE) is used, whereas when it explodes in confined spaces the term confined vapor cloud explosion (CVCE) is used. In a very poor or very rich fuel mixture, but still within flammability limits, the flame front travels in the cloud at low velocity and insignificant pressure increase—a phenomenon known as flash fire.

Based on the accident investigation, the explosive energy was equivalent to 0.3 ton TNT. Therefore the fraction of energy manifested in the explosion is 0.3/2.69 = 11.2%. This 11.2% is considerably higher than the 2% normally observed (see section 6-13) for unconfined vapor cloud explosions. The higher energy conversion is a result of the explosion occurring in a partially confined area. [Pg.551]

Unconfined vapor cloud explosion explosive oxidation of a flammable vapor cloud in a nonconfined space (e.g., not in vessels or buildings) the flame speed may accelerate to high velocities and can produce significant blast overpressures, particularly in densely packed plant areas. [Pg.232]
