Study Notes
OSHA Electrical Safety Standards
- OSHA's electrical standards are primarily based on the National Electrical Code (NEC).
- ANSI standards and NIOSH regulations play a lesser role in guiding these standards.
Types of Electrical Injuries
- Main electrical injuries include electrocution, electric shock, burns, and indirect injuries (e.g., falls).
Mechanism of Electric Shock
- Electric shock occurs when the body becomes part of the electrical circuit.
Severity of Electric Shock
- Shock severity is influenced by exposure time, current amount, frequency, and current path.
Electrical Burns
- The most serious burns from electricity typically occur on the hands due to direct contact.
Identification of Hot Wires
- Hot wires, which can cause shock, are usually colored black or red.
Causes of Electrocution
- Over 50% of electrocutions result from direct contact with energized power lines.
Flexible Cord Requirements
- Flexible cords must be rated for hard or extra-hard usage as per OSHA standards.
Common Electrical Violations
- The most frequent OSHA electrical standard violation is improper grounding of circuits and equipment.
Electrical Safety Program Elements
- A basic electrical safety program involves recognizing, evaluating, and controlling hazards.
Handling Damaged Tools
- Damaged portable electric tools should be removed from use and tagged "Do Not Use."
Plug and Receptacle Use
- For a three-prong plug with a two-hole receptacle, an adapter with a grounded wire is acceptable.
Power Tool Safety Rules
- Follow five basic rules including keeping tools in good condition and using the right tool for the job.
Protection from Electric Contact
- Live parts over 50 volts must be guarded against accidental contact to ensure worker safety.
Lockout/Tagout Procedures
- Circuits that can be accessed must be locked out or tagged out to prevent accidental energization.
AEGCP Implementation
- AEGCPs oversee power connections, cord sets, and receptacles that are not part of a building structure.
Ground-Fault Circuit Interrupter (GFCI)
- GFCIs protect from shock by monitoring current input and output, shutting down if an imbalance is detected.
Power Line Accident Causes
- Most power line accidents stem from failures to maintain proper work distances.
