Abstract: A PROCESS AND APPARATUS IS DESCRIBED TO MINIMIZE THE DANGER OF AERIAL EXPOLSIONS WHICH OCCUR DURING THE HIGH PRESSURE, HIGH TEMPERATURE POLYMERIZATION OF ETHYLENIC MONOMERS. THE PROCESS INVOLVES RAPIDLY DISCHARGING AT LEAST 0.3 KG. OF WATER PER KG. OF REACTOR CONTENTS INTO THE SAFETY PASSAGEWAY AND OUTLET PIPE WITHIN 10 SECONDS FOLLOWING THE OPERATIVENESS OF SUCH SAFETY PASSAGEWAY BY THE OPENING OF VALVE MEANS WHEN AN EXCESSIVE PRESSURE LEVEL IS REACHED WITHIN THE REACTOR. VARIOUS APPARATUS STRUCTURES ARE ALSO DISCLOSED ADAPTED FOR PRACTICING THIS PROCESS WHEREIN THE WATER IS HELD IN RUPTURABLE BAGS OR, E.G., IS DISCHARGED INTO THE ESCAPING GAS STREAM THROUGH VALVE-OPERATED SPRAY MEANS, OR IN OTHER WAYS.
