3 Terms and definitions

The following terms and definitions apply to this document.

3.1 Hazardous chemicals Highly toxic chemicals and other chemicals which are hazardous to the human body, facilities, and the environment with properties such as toxicity, corrosion, explosion, combustion, combustion-supporting.

3.2 Unit Production and storage devices, facilities, or sites involving hazardous chemicals, which are divided into production unit and storage unit.

3.5 Production unit Devices and facilities for the production, processing, and use, etc. of hazardous chemicals. When there is a shut-off valve between the device and the facility, USE the shut-off valve as separation boundary to divide into independent units.

3.6 Storage unit A relatively separate area of storage tanks or warehouses used to store hazardous chemicals. The area of storage tanks, using the fire dike of the tank area as the boundary, is divided into independent units.
