Structure of safety instructions
....................................................................................................................................................................................................................................
General structure
All safety instructions include a warning symbol and a signal word
that classify the danger, and a text block that contains descriptions of
the type and cause of the danger, the consequences of ignoring the
safety instruction and the measures that can be taken to minimise the
danger.
Example:
DANGER
Arcing on removing or inserting a live power supply
plug.
Arcing can cause burns to the hands and damage to the
eyes.
Ensure that the line circuit breaker on the Power
Interface (PI) is in the “OFF” position before removing
or inserting the power supply plug.
Danger classification
There are three classes of safety instructions: “DANGER”,
“WARNING” and “CAUTION”. Which class is relevant depends on
the consequences of ignoring the safety instruction:
DANGER
Serious injury is definite or likely.
WARNING
Serious injury is possible.
CAUTION
Minor injury is definite, likely or possible, or
material damage to the product or in the product
environment is definite or likely.
