Normally, the Life Safety Code is used by architects and designers of vehicles and vessels used for human occupancy. Since the Life Safety Code is a valuable source for determining liability in accidents, it is also used by insurance companies to evaluate risks and set rates, not to mention assessment of compliance after an incident.
Operational safety refers to the state in which the risk to life, health, property, or the environment from a system or subsystem in an operational setting is maintained at an acceptable level.

A safety-critical system is designed to lose less than one life per billion (10 9) hours of operation. [7] [8] Typical design methods include probabilistic risk assessment, a method that combines failure mode and effects analysis (FMEA) with fault tree analysis. Safety-critical systems are increasingly computer-based.
Occupational safety and health (OSH) or occupational health and safety (OHS) is a multidisciplinary field concerned with the safety, health, and welfare of people at work (i.e., while performing duties required by one's occupation).

From a safety standpoint, EHS involves creating organized efforts and procedures for identifying workplace hazards and reducing accidents and exposure to harmful situations and substances. It also includes training of personnel in accident prevention, accident response, emergency preparedness, and use of protective clothing and equipment.
