Electrical Safety Hazards

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 first step in performing a live-dead-live test is to confirm the test instrument is working properly.
• 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.
• The OSHA LOTO rule applies to many workplaces, not just electrical work.
• Distance is the best protection against electrical shock hazards.
