Safety Assessment is described and required by different safety standards and guidelines like MIL-STD-882C, DI-SAFT-80102A, MIL-STD-1472, SAE ARP 4761, SAE 4754A FAR/CS 25.1309, FAR/CS 27.1309, FAR/CS 23.1309 and other documents.

System Safety Assessment may be performed on Design, Production and Field use life cycle phases of the product.

It is extremely important for mission-critical and safety-critical products of aviation, aerospace, defence, railway and other industries.

The Safety Assessment Analysis includes:
• Safety criteria and a hazard classification procedure.
• Results of safety analyses performed.
• Identified risks still existing and constituting a hazard to operators and maintenance personnel.

• A hazards list and recommendations for their elimination or reduction to an acceptable level.

• An assessment of the system compliance with the safety requirements.
