The Globally Harmonised System (GHS) defines and classifies the hazards of chemical products and communicates health and safety information on labels and safety data sheets. The goal is that the same set of rules for classifying hazards, and the same format and content for labels and safety data sheets (SDS) will be adopted and used around the world.
Cooling In the chemical process industry runaway reactions (exotherms) in process vessels are sometimes a concern. In order to prevent such reactions, one of the critical controls is temperature control. This is done by removing the heat generated by the reaction by means of vessel cooling jackets using a cold medium (such as water). Environments in which there is a risk of explosion pose several challenges in terms of protecting vital equipment. Such hazardous environments include industrial refineries, chemical plants, and offshore oil platforms. Protecting electronic equipment in these settings often means enclosing it (explosion proof). To prevent overheating and failure, such equipment is usually cooled by the use of fans. LPG storage vessels are fitted with water deluge systems. In the event of a fire in the vicinity of the sphere, the deluge system activates. The vessel is cooled thus prevent its rupture, release of contents and vapour cloud explosion.
