Faulty or overloaded equipment can lead to fires which can cause damage, injuries and loss of life.
- work in or on excavations.
- working in wet, harsh or confined conditions.
- working on or near overhead lines, for example tipping loads.
- working on or near equipment that’s thought to be dead but has a live current.

What are the risks of faulty electricity equipment?
The main hazards of working with electricity are: electric shock and burns from contact with live parts. injury from exposure to arcing, fire from faulty electrical equipment or installations.
What is the most common cause of electrical failure?
Primary Causes of Electrical Equipment Failure
- Loose connections or parts.
- Power line disturbance.
- Defective or inadequate insulation.
- Foreign object or short circuits.
- Overloading or inadequate power capacity.
What are the 3 hazards of electricity?
There are three main types of electrical hazards: electric shock, electrical burns, and arc blasts (the effect of blasts). Understanding the basics of these hazards is critical in enforcing electrical safety in the workplace.
What problems can occur during electrical maintenance?
An employee was trying to apply insulating tape to a live electrical cable but received an electric shock.
- Inadequate information.
- No training.
- Inadequate isolation.
- Unsafe rules.
- Poor control of work activities.
- Live working.
- Unsuitable test equipment.
- Poor maintenance.
What are the 5 main electrical hazards?
The five hazards described here are very common and easily preventable, making them a great topic for a safety meeting or toolbox talk.
- Working on live circuits.
- Skipping lockout/tagout.
- Forgetting PPE.
- Improper grounding.
- Damaged extension cords.
What are some electrical hazards?
Common types of electrical hazard include:
- Contact with live wires resulting in electric shock and burns,
- Fires due to faulty wiring,
- Exposed electrical parts,
- Ignition of fires or explosions due to electrical contact with potentially flammable or explosive materials,
- Inadequate wiring,
What is malfunctioning electrical equipment?
The commonest cause of electrical problems is faulty electrical appliances. And the commonest electrical problem is tripped circuit breakers. When a circuit breaker detects a surge of electricity from a malfunctioning electrical appliance it instantly shuts the circuit down.
What causes electronics to fail?
Failures can be caused by excess temperature, excess current or voltage, ionizing radiation, mechanical shock, stress or impact, and many other causes. In semiconductor devices, problems in the device package may cause failures due to contamination, mechanical stress of the device, or open or short circuits.
How can we prevent faulty electrical equipment?
Preventative Steps and Safe Work
- Inspect wiring of equipment before each use.
- Use safe work practices every time electrical equipment is used.
- Know the location and how to operate shut-off switches and/or circuit breaker panels.
- Limit the use of extension cords.
- Multi-plug adapters must have circuit breakers or fuses.
What is an electrical risk?
An electrical risk is a risk to a person of death, shock or other injury caused directly or indirectly by electricity. Contact with exposed live parts causing electric shock and burns (for example, exposed leads or other electrical equipment coming into contact with metal surfaces such as metal flooring or roofs).
