OSHA #511 Occupational Safety and Health Standards for General Industry course

What does OSHA require for live parts of electric equipment operating at 50 volts or more?

1. No guarding requirements

2. Guarding against accidental contact

3. Periodic check for insulation damage

4. Marking with warning signs only

The correct answer is: Guarding against accidental contact

The requirement for guarding against accidental contact with live parts of electric equipment operating at 50 volts or more is crucial for ensuring safety in the workplace. This provision helps prevent electrical shocks that can lead to serious injury or fatalities. Guarding can take various forms, including barriers or enclosures, that effectively prevent workers from coming into accidental contact with these hazardous components. While other measures such as marking with warning signs, checking for insulation damage, or having no guarding requirements might address different aspects of safety, they do not provide the same level of protection as physically guarding live parts. Guarding is a proactive measure that is essential for protecting individuals who may be working near or with electrical equipment, thus minimizing risks associated with electrical hazards. This focus aligns with OSHA's overarching goals of ensuring safe working conditions and reducing workplace injuries.
