Does Intrinsically Safe Cable Have to Be Blue?

Intrinsically safe cables are usually coloured blue so as to identify the potential risk of the electric circuit and the need for special consideration. The cables are often protected by tough sheathing materials such as polyurethane to prevent any mechanical damage which could compromise electrical safety.

What makes a cable intrinsically safe?

Intrinsically Safe cables contain a blue coating that identifies the potential risk of the electric circuit and the need for special consideration. Furthermore, strong sheathing materials such as polyurethane protect the cables to prevent any mechanical damage that could compromise electrical safety.

What color shall be permitted to identify intrinsically safe conductors?

Color coding shall be permitted to identify intrinsically safe conductors where they are colored light blue and where no other conductors colored light blue are used.
