The boiling, foul-smelling liquid is expelled violently through an outlet valve, with a loud popping sound. The beetles' glands store enough hydroquinone and hydrogen peroxide to allow the beetle to release its chemical spray roughly 20 times.
Brachinus texanus is a species of ground beetle in the genus Brachinus ("bombardier beetles"), in the family Carabidae ("ground beetles"). [1] [2] [3] It is found in North America. Like other bombardier beetles, it can spray a boiling, corrosive liquid from its abdomen if provoked, and as such should not be handled. [2]
The bombardier beetle is unusual by using a violent exothermic chemical reaction to launch a boiling noxious chemical spray in a rapid burst of pulses from special glands in its abdomen, accompanied with a popping sound. The Anthia (oogpister beetle) will fire formic acid at
BLEVE–fireball, 2008 Toronto propane explosion The following is a list of boiling liquid expanding vapor explosion (BLEVE) accidents. It shows whether the accident occurred during dangerous goods transportation or at a fixed facility, the accident origin (e.g., storage, process reactor, rail tank car, tank truck), the material involved, its amount, the number of fatalities, and whether a ...
Liquid oxygen has a clear cyan color and is strongly paramagnetic: it can be suspended between the poles of a powerful horseshoe magnet. [2] Liquid oxygen has a density of 1.141 kg/L (1.141 g/ml), slightly denser than liquid water, and is cryogenic with a freezing point of 54.36 K (−218.79 °C; −361.82 °F) and a boiling point of 90.19 K (−182.96 °C; −297.33 °F) at 1 bar (14.5 psi).
A BLEVE–fireball at the Philadelphia Energy Solutions refinery, as rendered by the CSB. A boiling liquid expanding vapor explosion (BLEVE, / ˈ b l ɛ v iː / BLEV-ee) is an explosion caused by the rupture of a vessel containing a pressurized liquid that is or has reached a temperature sufficiently higher than its boiling point at atmospheric pressure.
“The delay allows teams to complete data analysis on a pressure regulation valve on the liquid oxygen tank of the Atlas V rocket's Centaur upper stage and determine whether it is necessary to ...
