SAFE STORAGE AND TRANSPORTATION OF SOME POTENTIALLY HAZARDOUS MATERIALS
MANY MATERIALS WHICH ARE STORED AND TRANSPORTED IN BULK UNDERGO EXOTHERMIC DECOMPOSITION OR OXIDATION REACTIONS AT ELEVATED TEMPERATURES. SUCH REACTIONS MAY RENDER THEM LIABLE TO SPONTANEOUS IGNITION IF THEY ARE IN SUFFICIENT QUANTITY AND AT SUCH A TEMPERATURE THAT THE RATE OF HEAT PRODUCTION EXCEEDS THE RATE AT WHICH HEAT IS ABLE TO BE TRANSMITTED TO THE SURROUNDINGS. STEADY-STATE THERMAL EXPLOSION THEORY HAS BEEN USED TO PREDICT SAFE STORAGE AND TRANSPORTATION (CRITICAL MASSES) AT A SERIES OF TEMPERATURES FOR THREE REPRESENTATIVE TYPES OF SELF-HEATING MATERIALS - BALED WOOL, POWDERED AMMONIUM NITRATE AND A SOLUTION OF METHYLETHYL KETONE (2-BUTANONE) PEROXIDE (40%) IN DIMETHYL PHTHALATE. THE NON-STEADY-STATE THEORY (REACTANT CONSUMPTION ADMITTED) HAS BEEN USED TO ESTIMATE THE TIME TAKEN FOR THESE CRITICAL MASSES TO REACH THE CRITICAL STATE AT EACH TEMPERATURE. THE CRITICAL MASSES HAVE BEEN SHOWN TO BE CONSISTENT WITH SAFETY REQUIREMENTS AT PRESENT ACCEPTED FOR THE STORAGE AND TRANSPORTATION OF THE MATERIALS DISCUSSED. THE ESTIMATES OF THE TIMES TAKEN BY THE CRITICAL MASSES TO REACH THE CRITICAL STATE BRING AN ADDED DIMENSION TO THE CRITICAL MASS CALCULATIONS, AND TOGETHER THESE RESULTS CONSTITUTE AN ADVANCE OVER THE PRESENT SITUATION WHERE SAFE LIMITS HAVE BEEN DEDUCED ON A TRIAL AND ERROR BASIS. /AUTHOR/
