WHY DO WE NEED SAFETY
ENGINEERING?
It also requires government and industry to
collaborate to improve safety as a joint project
Not Independently

WHAT IS SAFETY ANALYSIS?
Safety Analysis is a genetic term for study of
the system, identification of dangerous aspects
of the system, and correction of them.

WHAT IS SAFETY ANALYSIS?
System Safety is the formal name for a
comprehensive and systematic examination of
an engineering design or mature operation and
control of any particular hazards that could
injure people or damage equipment.

WHAT IS SAFETY ANALYSIS?
System Safety Engineering is a collecting of
engineering
analyses
and
management
practices that control dangerous situations.

SYSTEM SAFETY ENGINEERING
Identify the hazards in a system
Determine the underlying causes of those hazards
Develop engineering or management controls to either
eliminate the hazards or mitigate their consequences
Verify that the controls are adequate and in place
Monitor the system after it has been changed and
modify further as needed

SYSTEM SAFETY AND RISK ASSESSMENT
Many engineers confuse system safety with
risk assessment and use the terms
interchangeably.

SYSTEM SAFETY AND RISK ASSESSMENT
System Safety
• Is the assurance and management that the system is
safe for all people, environment, and equipment.
Risk Assessment
• Like system safety engineering, can be used to
determine how safe something is, but it also can be
used to determine the various trade-off alternatives to
lower the risk in a system.

How do I balance the business risks with
the safety risks?
