Layout design development is supported by a number of studies and reviews, including:

• Hazard identification (HAZID Study) and risk assessments - both qualitative and quantitative.

• Operability reviews.

• Constructability review.

• Explosion venting studies may be used in developing the plant layout.

• A maintainability and logistics evaluation for storage and materials handling requirements etc.

• Truck and train movement and materials handling study to determine best location for plant entries and exits.

• Location trade-off studies that identify which equipment poses the higher potential risk.
