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.
