Cheat Sheet
- OSHA 1910.147 Lockout/Tagout Basics -
Familiarize yourself with the lockout tagout safety quiz answers by reviewing OSHA 1910.147, which sets federal requirements for controlling hazardous energy during machinery servicing. Knowing the definitions of lockout and tagout devices ensures you can answer osha electrical lockout/tagout quiz questions confidently. Use official OSHA and NIOSH publications to reinforce your understanding.
- Energy-Isolating vs. Control Devices -
Understand which of the following is not an energy isolating device by distinguishing fixed mechanical devices - like gate valves and disconnect switches - from push buttons or selector switches, which are merely control devices. Remember the memory aid "Gate, Valve, Switch" for true energy isolators and avoid confusion in your answers. Refer to ANSI/ASSE and NFPA guidelines for detailed classifications.
- Seven Steps for Effective Lockout/Tagout -
Master the seven-step procedure: prepare, notify, shut down, isolate, lock, tag, and verify stored energy is zero. Use the mnemonic "PN SIL TV" (Prepare, Notify, Shut, Isolate, Lock, Tag, Verify) to retain the sequence for your lockout tagout safety quiz answers. Academic sources like university safety engineering courses often break down each step with practical examples.
- Servicing and Maintenance Timing -
Servicing and maintenance are safest to perform when all hazardous energy sources are isolated and verified at zero stored energy - commonly called "zero-energy state." This principle is core to lockout devices and tagout devices must follow guidelines to keep workers safe. Studies from OSHA case data and IEEE 1584 emphasize the importance of energy verification before any maintenance begins.
- Lockout and Tagout Device Requirements -
Lockout devices and tagout devices must be durable, standardized in color and print, and scalable to fit various energy sources; locks typically use red for immediate recognition. A handy mnemonic is "DSPC": Durable, Standardized, Printed, Color-coded. The Practice Safety Council and OSHA-compliant online courses provide detailed specs for these devices.
