Electrical Hazards, Utilization, and Safety Measures

Vocabulary flashcards covering electrical energy fundamentals, sector consumption types, efficiency concepts, hazards, and safety principles.

Electricity

The flow of electric charge, usually through wires, or the movement of electrons through a conductor that produces energy used for light, heat, and power.

Utilization of Electricity

The process of converting electrical energy into useful forms of energy like light, heat, or mechanical work to perform specific functions.

Primary Sources

Energy sources obtained directly from natural resources, such as coal, wind energy, and nuclear energy.

Secondary Sources

Energy produced from primary energy sources, such as electricity generated from wind, solar, or hydro energy.

Long-term Demand Forecasting

The estimation of future electricity demand over many years so that enough power plants and infrastructure can be planned and built to provide a reliable electricity supply.

Residential Consumption

Electricity used in homes and households for lighting, electric fans, air conditioners, refrigerators, televisions, computers, washing machines, and cooking appliances.

Commercial Consumption

Electricity used in businesses and institutions, such as offices, schools, hospitals, hotels, restaurants, and retail stores, to power essential operational equipment and systems.

Industrial Consumption

Electricity used by factories, manufacturing plants, mines, and other industrial facilities to operate machinery, equipment, and production processes.

Energy Efficient

A characteristic of devices or practices that use less energy to do more work, save money on electricity or fuel bills, and protect the environment by reducing pollution.

Energy Inefficient

A characteristic of devices or practices that use more energy than needed to do a job, costing more money to run and wasting resources.

Energy Loss

The unavoidable dissipation of energy occurring naturally during transfer or use due to thermodynamic limitations, friction, or equipment design.

Energy Waste

The unnecessary use or consumption of energy resulting from poor habits, neglect, or improper behaviors like leaving lights on in empty rooms.

Overloading Circuits

An electrical hazard caused by plugging too many devices into a single outlet or circuit, which can cause overheating, fire, or equipment damage.

Damaged or Exposed Insulation

An electrical hazard involving cracked, frayed, or broken protective casing that exposes live wires, increasing the risk of electric shock or short circuits.

Octopus Wiring

The unsafe electrical practice of plugging multiple extension cords into a single power outlet.

Improper Wiring

Poorly executed wiring that fails to comply with safety standards, leading to short circuits, arcing, fire, or electric shock.

Electrocution Risk

An electrical hazard resulting from direct contact with live electrical parts, which can cause severe injury or death.

Awareness

A key electrical safety principle emphasizing the continuous observation and early identification of potential dangers like frayed wires, damaged plugs, or water near appliances.

Prevention

A key electrical safety principle focusing on simple proactive measures, such as unplugging unused devices and avoiding overloaded power strips, to stop hazards before they occur.

Responsibility

A key electrical safety principle requiring individuals to speak up about hazards, remind others to follow safety procedures, and ensure proper equipment operation.

Preparedness

A key electrical safety principle involving emergency readiness, such as knowing how to shut off power at the main breaker, using fire extinguishers, and contacting help.
