Study Notes

General Understanding of Electrical Hazards

Familiarity with electricity can lead to overlooking its hazards.
In 2017, OSHA cited over 4,600 electrical-related violations in workplaces.

Requirements for Electrical Current Flow

A current requires three components: a source of electrical current, a conductor, and a cause for current flow.

Effects and Types of Electrical Burns

Burns are the most common injury from electrical shock.
Electrical burns are serious and need immediate medical attention, resulting from current generating heat.
Arc or flash burns are caused by high temperatures from electric arcs, like lightning, and can melt metal.
Thermal contact burns result from contact with overheated surfaces or equipment.

Dangers of High Voltage Power Lines

Contact with high voltage lines can result in electrocution, which is often fatal.

Workplace Safety Equipment and Responsibilities

Employers must ensure the safe construction and installation of electrical equipment including lighting, switches, and controls.
Protection against electrical hazards includes avoiding circuit overloads, inspecting switches, and using extension cords correctly.

Ground Fault Circuit Interrupter (GFCI)

GFCIs are designed to prevent electrocution by monitoring electrical leakage and interrupting current flow if leakage exceeds 5 mA.
They sense current leaks, trip the circuit, and cut off electricity.

Lockout/Tagout Procedures

Lockout/tagout procedures prevent accidental activation of electrical equipment during maintenance.
Workers must place a tag on locked devices to indicate they should not be energized.

Identifying Electrical Hazards

Electrical hazards include shock, explosions, burns, fire, arc flash, and electrocution.
Situations involving hazards, like standing on wet floors while adjusting frayed wiring, necessitate caution.

Employer Responsibilities Under OSHA Regulations

Employers are required to provide and maintain effective electrical safety measures, including proper lighting, controls, and appliances in the workplace.
