    Study Notes

    Electrical Safety Hazards

    • OSHA's Focus Four hazards include fall, electrical, caught-in/between, and struck-by hazards.
    • Electrical current is the movement of electrons through a conductor.
    • The outer layer of skin provides the most electrical resistance for the human body.
    • Arc burns are caused by electric arcs.
    • The first step in making sure a circuit is off is to confirm the test instrument is working properly.
    • Unsafe conditions, equipment, and actions are the main causes of electrical incidents.
    • Elimination is the best way to reduce risk according to the hierarchy of risk controls.
    • Ground Fault Circuit Interrupter (GFCI) turns off a circuit when there is a ground fault.
    • Most electrical accidents occur with low-voltage conductors.
    • A live-dead-live test is used to ensure a circuit is off.
    • Fibrillation is the heart quivering due to an electric shock.
    • Warning sounds on a jobsite are considered an administrative control.
    • If you think a circuit is on, you should report it to a supervisor.
    • The main reason for using PPE is to reduce the risk of injury.
    • Chemical burns are not a type of burn caused by electrical accidents.
    • A competent person on a jobsite identifies hazards and takes corrective action.
    • After testing for zero voltage, you must lock out and tag the circuit.
    • PPE is a less effective risk control method than engineering controls or elimination.
    • Double-insulated tools insulate the case from electrical energy.

    • The human body is a good conductor of electricity.
    • NFPA 70E® sets standards for electrical safety at work.
    • If you find unsafe equipment on a jobsite, report it and do not use it.
    • Attending work on time is not part of the hierarchy of risk controls.
    • Unsafe actions are the main cause of electrical incidents.
    • An electric shock can cause the heart to stop beating and result in fibrillation.
    • CFR 1910 and CFR 1926 set safety regulations for workplaces.
    • If you see someone being shocked, turn off the power source immediately.
    • The frame or case of the tool being energized is the most common reason for electrical accidents involving handheld power tools.
    • A qualified person on a jobsite resolves problems related to the work or project.
    • Rubber insulating gloves are PPE used to protect against electrical hazards.
    • Class 1 rubber protective equipment is indicated by a white tag.
    • If you are unsure about the condition of rubber gloves, you should discard them.
    • A hot stick keeps you at a safe distance from energized parts.
    • OSHA sets standards related to the use of PPE on electrical jobs.
    • Arc flash shields are not optional when working on or near energized circuits.
    • Insulated blankets can be used on the floor as a protective measure.
    • Safety glasses are required at all times when working on or near energized circuits.
    • A discharge probe is used before working on de-energized circuits with capacitors installed.
    • Before using insulated blankets, you should inspect them before each use.
    • OSHA's purpose is to ensure safe and healthful working conditions for workers.
    • Employers must provide a workplace free from recognized hazards.
    • Inspecting and properly storing PPE is an employee responsibility for electrical safety.
    • The OSHA Lockout/Tagout (LOTO) rule prevents unexpected energization or startup of equipment.
    • Maintaining a safe distance is the BEST protection against electrical shock hazards.
    • Employees are responsible for inspecting and properly storing their PPE.
    • Job safety planning and a job briefing are required before starting each task.
