AbstractSafety considerations in the planning of chemical plant. The author shows how the safety concept of a chemical plants is developed on the basis of the process, the properties of the materials, the operating conditions, and the plant location. The basic considerations for a complete and balanced safety concept are addressed. It is demonstrated how, in the case of a large chemical facility, safety considerations undertaken in up to three stages can already ensure the necessary high safety level of a chemical plant during the planning stage.
