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.
