INCOMPATIBILITY RISKS ON PARCEL CHEMICAL TANKERS-- CAPT AJIT VADAKAYIL






DANGERS OF IMPROPER STOWAGE AND CARELESS CARRIAGE OF LIQUID CHEMICALS           
          
                Explosive when dry
                Risk of explosion by shock, friction, fire or other sources of ignition
                Forms very unstable explosive metallic compounds
                External heating may cause an explosion
                May form explosive peroxides
                Explosive due to vigorous reaction or reaction products may produce detonation
                Explosive when mixed with oxidizing substances
                Explosive when mixed with combustible material
                Heat generated from chemical reaction may initiate explosion
                May cause fire
                Contact with combustible material may cause fire
                Spontaneously flammable in air
                Fire from exothermic reaction-ignition of products or reactants
                Flammable gas generation
                Flammable, toxic gas generation; causes pressurization
                Heat generation by chemical reaction, may cause pressurization
                Dangerous heat generation due to heat of solution
                Violent polymerization, possibly with heat/toxic or flammable gas   generation
                Can become highly flammable in use; causes pressurization
                Contact with substance liberates toxic gas; causes pressurization
                Innocuous and nonflammable gas generation; causes pressurization
                Contact with acids produces combustion enhancer (e.g., O2)
                Generates water soluble toxic products
                May be hazardous but unknown
                Reaction may be intense or violent
                Possible exposure to radiation

Stability During Transport - The term "Stable" means that the chemical will not decompose in a hazardous manner under the conditions of temperature, pressure, and mechanical shock that are normally encountered during shipment; the term does not apply to fire situations. Where there is a possibility of hazardous decomposition, an indication of the conditions and the nature of the hazard is given.
