What is functional safety?

What is it?

Functional safety is the part of overall plant safety that depends on the correct operation of safety-related systems. The goal is to control intolerable risks through the use of electrical, electronic, and programmable electronic systems (E/E/PES).

Why does it matter?

Implementing functional safety is a legal requirement and critical to protecting people, the environment, and assets. It ensures safe operation of processes, prevents costly incidents, and secures legal compliance.
