1.4 Electrical Shocks and Arc Flashes Can Cause

Severe Personal Injury or Death

WARNING

Electric Shock Hazard

Voltages and currents present an electrical shock hazard that can cause

severe burns or death.

Contact with exposed energized circuits with potentials of 50 Volts AC or 75

Volts DC or higher can cause electrical shock and electrical arc flash. Refer

to standard NFPA 70E or equivalent safety standards in corresponding

regions for details of the dangers involved and for the safety requirements.

Guidelines to follow when working on de-energized electrical systems:

• Use proper PPE. Do not wear jewelry and make sure that any conductive items

are removed from pockets as these items can fall into equipment and the

resulting short circuit can cause shock or burning. Refer to standard NFPA 70E

for PPE standards.

• De-energize and lockout/tagout electrical systems prior to working on them.

Lockout/Tagout is intended to prevent injury due to unexpected start-up of

equipment or the release of stored energy. Please refer to Locking the

Generator Set Out of Service section for more information.

• De-energize and lockout/tagout all circuits and devices before removing any

protective shields or making any measurements on electrical equipment.

• Follow all applicable regional electrical and safety codes.
