2.5 Special types of risks

DANGER

Bare conductors or main line carriers

Danger to life or serious injury is possible due to contact with high electric voltage when working

with bare conductors or main line carriers.

• Please observe relevant regulations on occupational safety and health.

• If necessary, use appropriate protective equipment.

WARNING

Dangerous voltage

Danger to life or serious injury is possible due to contact with high electric voltage when working

on live components or equipment. Even low voltages from 30V‑AC and 60V‑DC on can be

dangerous to human life!

• Please observe relevant regulations on occupational safety and health.

• If necessary, use appropriate protective equipment.
