In accordance with Article 5.6.1 of the \"Code for Design of Chemical Industry Heating, Ventilation and Air Conditioning\" (HG/T20698-2009), \"Rooms where harmful gases or gases with explosion risks may be released in large quantities suddenly should be equipped with an emergency ventilation system.\" ”May I ask whether “possible sudden massive release” here refers to a sudden release under normal conditions or one under abnormal conditions? Does it include sudden massive release caused by overpressure rupture or explosion of the equipment? “The scale expressed by the word “possibly” is difficult to determine.
