3. Causes of the emergencies

Industrial emergency occurs due to release of chemicals from an industry. Chemicals are stored in bulk at various storage conditions like at high pressure and/ or high temperature or at cryogenic conditions. Chemicals are either stored in gaseous phase or liquid or in both phases. When these chemicals released out into the atmosphere, then based on their nature these chemicals either will ignite or may explode or if it is toxic then will spread in a plume in the local area.

The behaviour of the chemicals is shown in Fig-2.
