🔍 Key Concepts

• Lockout/Tagout (LOTO) safety procedures for machinery maintenance • Risks of stored energy and accidental startup in pressurized systems like air compressors • Primary purpose of tagging and securing valves before maintenance

💭 Think About

• Ask yourself: If the system was accidentally started or pressurized while someone is working on it, what could happen to the person and the machinery? • Consider whether wiring and tagging valves closed serves only one purpose (like equipment protection), or if it addresses several safety concerns at once. • Think about OSHA/USCG safety culture: When we apply tags and locks, whose safety are we MOST trying to ensure?

✅ Before You Answer

• Verify which option best reflects the main goal of lockout/tagout procedures. • Check whether wiring and tagging valves closed can both prevent unexpected operation and protect equipment, or if its primary intent is focused on something else. • Before choosing, ask: In an exam context, what is usually considered the highest priority in any maintenance or safety procedure?
