MAPO
detonation velocity, confined:
8260 m/s = 27100 ft/s at r = 1.73 g/cm3 deflagration point: 185 °C = 365 °F
impact sensitivity: 0.08 kp m = 0.8 N m
Nitromannitol is insoluble in water, but is soluble in acetone, ether and
hot alcohol; it is difficult to stabilize.
It is prepared by dissolving mannitol in cold concentrated nitric acid
and precipitating it with cold concentrated sulfuric acid. The crude
product is washed with a dilute bicarbonate solution and with water,
and is then recrystallized from hot alcohol.
In the USA nitromannitol was used as a filling for W Blasting Caps.
MAPO
Abbreviation for methylaziridine phosphine oxide, a bonding agent for
AP containing W Composite Propellants.

Mass Explosion Risk

Massen-Explosionsfähigkeit, Massen-Explosionsgefährlichkeit;
danger d’explosion en masse
A term describing the behavior of explosive materials and items
(chiefly ammunition) in bulk. The question to be answered is whether a
local explosion or fire will or will not detonate the entire bulk of the
explosive (a truckload, or even a shipload of explosives). A number of
tests have been laid down, in which first a parcel, then a case, and
finally a caseload – in the form in which it is to be dispatched – are
primed or inflamed in the manner in which this is to be done in actual
service. When testing a caseload, the cases are arranged in predetermined
locations, covered by inert cases of identical construction,
and ignited.
Mass explosion risk does not depend solely on the properties of the
explosive material, but also on the stacking height (in extreme cases,
an entire shipload), on the nature of the confinement (e.g., buildings,
