Study Notes

Electrical hazards

Electrical hazards are dangerous occurrences associated with electrical systems.
Electrical hazards can cause burns, electrocution, arc flash, electric shock, and other serious injuries.
Electrical hazards can also lead to fires and explosions.
Electrical hazards affect life, property, and workplace safety.

### Causes of Electrical Hazards

Insufficient Insulation: Over time, electrical insulation can deteriorate due to wear and tear, rodents, or moisture. This can lead to exposed wires and increase the risk of electric shock or short circuits.
Circuit Breaker Failure: If a circuit breaker fails to trip during an overload, it fails to protect, increasing the risk of electrical hazards.
Damaged Electrical Appliances: Loose connections, frayed wires, or cracked insulation in electrical appliances lead to electrical malfunctions.
Improper Use of Extension Cords: Overloading and daisy-chaining extension cords can cause overheating and electrical fires.
Inadequate Maintenance: Failing to inspect electrical systems regularly, ignoring warning signs, and bypassing safety procedures can lead to severe electrical hazards over time.

Examples of Electrical Hazards

Overhead Power Lines
Damaged or faulty tools and equipment
Exposed electrical parts
Inadequate wiring and overloaded circuits
Improper grounding
Damaged insulation
Wet conditions

### Preventing Electrical Hazards

Prevent electrical equipment from contacting wet areas.
Ensure safe unplugging practices.
Install electrical cords properly and keep them tidy.
Understand your switchboard.
Look out for electrical lines.
Childproof outlets.
Investigate flickering lights.
Install warning signs.
Avoid DIY electrical repairs.
Call for professional help.

Conclusion

Electrical hazards are a significant threat to workplace safety.
