Safety in Engineering


Safety engineering is an applied science strongly related to system engineering.

Safety engineering assures that a life-critical system behaves as required even when pieces fail.

In the real world the term "safety engineering" refers to any act of accident prevention by a person qualified in the field.


To perform their professional functions, safety engineering professionals must have education, training and experience in a common body of knowledge. They need to have a fundamental knowledge of science, engineering, business, communications, and psychology. Professional safety studies include industrial hygiene and toxicology, design of engineering hazard controls, fire protection, ergonomics, safety and health program management, accident investigation and analysis, measurement of safety performance, human behavior, environmental safety and health, health and environmental laws, regulation and standards.

Many safety engineers have backgrounds or advanced study in other disciplines, such as management and business administration, engineering, education, physical and social sciences and other fields. Others have advanced study in safety. This extends their expertise beyond the basics of the safety engineering profession


Engineers may encounter situations that have the potential to be dangerous. Examples of such situations include

presence of high voltages, high temperatures, high velocities, toxic chemicals, and large amounts of energy.


An engineer carries a serious responsibility when designing or supervising a project, because failure to act to correct a dangerous situation or failure to follow a code or a standard is a professional misconduct.


Some General Guidelines to Deal with Hazards


Identify the hazard

Try to eliminate the cause of the hazard

If the hazard cannot be eliminated, then actions should be taken to reduce it or protect the workers and public from its consequences.
