Electricity Safety Awareness

What are the common electrical hazards in the workplace?

• Using extension cords for permanent wiring

• Properly insulated cables

• Exposed wires, overloaded circuits, improper grounding, wet conditions, lack of PPE.

• Routine equipment maintenance

How can you identify a damaged extension cord?

• Check for a strong smell of plastic.

• Ensure the cord is plugged in properly.

• Look for a shiny surface on the cord.

• Look for frayed wires, cracks, burn marks, and test for functionality.

What is the purpose of grounding in electrical systems?

• To increase the voltage in electrical systems.

• The purpose of grounding is to ensure safety by preventing electrical shock and protecting equipment.

• To improve the efficiency of electrical devices.

• To enhance the aesthetic appeal of electrical installations.

What type of personal protective equipment is essential when working with electricity?

• Steel-toed boots, reflective jackets, and gloves

• Insulated gloves, safety goggles, and dielectric footwear

• Hard hats, earplugs, and respirators

• Safety vests, knee pads, and face masks

How should extension cords be used to prevent hazards?

• Connect multiple extension cords together for longer reach.

• Use extension cords properly by not overloading, keeping them dry, and inspecting for damage.

• Always cover extension cords with rugs or furniture.

• Use extension cords only outdoors regardless of conditions.

What is the difference between grounding and bonding?

• Grounding is for safety; bonding is for aesthetics.

• Grounding connects to the earth; bonding connects electrical components together.

• Grounding prevents electrical fires; bonding prevents power surges.

• Grounding is only for outdoor use; bonding is only for indoor use.

What safety measures should be taken when using power tools?

• Wear PPE, keep the work area clean, check tools for damage, follow instructions, and use tools as intended.

• Ignore the manufacturer's instructions

• Leave the work area cluttered

• Use tools without any safety gear

What should you do if you encounter a downed power line?

• Try to move the line out of the way.

• Approach the line to inspect it closely.

• Stay away and report it to authorities.

• Wait for someone else to handle it.

How can you safely store extension cords when not in use?

• Leave extension cords on the floor to avoid tangling.

• Store extension cords in a damp basement for easy access.

• Store extension cords coiled in a cord organizer or storage bin, ensuring they are clean and dry.

• Hang extension cords on nails in the garage.

What are the signs of electrical overload in a circuit?

• Normal operation of all devices

• Stable circuit temperature

• Signs of electrical overload include overheating wires, tripped breakers, blown fuses, flickering lights, and burning smells.

• Consistent voltage levels
