Electrical Safety Precautions Quiz

General Safety Precautions

• Always remove power from circuits and equipment before working on them.
• Never bypass safety mechanisms.
• Ensure all equipment is properly grounded.
• Exercise caution when handling batteries, especially those containing acid.
• Use cleaning fluids in well-ventilated areas.
• Dispose of flammable materials in sealed metal containers.
• Immediately de-energize and report any electrical fires.

High Voltage Safety Precautions

• Never work on high-voltage circuits alone.
• Always have a partner trained in CPR and first aid.
• Avoid contact with live circuits.
• Do not tamper with safety interlocks.
• Use an isolation transformer to protect yourself.
• Never work on equipment in the presence of water.

Personal Safety Precautions

• Work in clean and dry areas.
• Avoid loose clothing, as it can conduct electricity.
• Wear non-conductive shoes to reduce the risk of shock.
• Remove all metallic objects, including jewelry and watches.
• Use insulated tools to handle hot parts.
• Discharge capacitors using a shorting stick.
• Ensure proper grounding of test equipment.
• Disconnect power before connecting alligator clips.
• Avoid touching test probes when working on circuits with voltages above 300 volts.

Fire Safety

• Class A fires involve materials like wood, paper, and cloth.
• Use water or a carbon dioxide extinguisher for Class A fires.
• Class B fires involve flammable liquids like gasoline and kerosene.
• Smother Class B fires with foam or carbon dioxide.
• Class C fires involve electrical equipment. Cut off power and use a non-conductive dry powder or carbon dioxide extinguisher.

Electrical Shock

• Electrical shock occurs when an electric current passes through the body.
