🔍 Key Concepts

• Lockout/Tagout (LOTO) safety purpose • Difference between PERSONNEL safety and EQUIPMENT protection • Meaning of a DANGER tag versus a CAUTION or OUT-OF-SERVICE tag

💭 Think About

• Is a DANGER tag used only when people could be hurt, or also when the machinery itself could be damaged? • Think about the wording you would want to see if you were about to start equipment that someone was working on—what risk is that tag trying to prevent? • Which option best reflects the most conservative, safety‑first policy used in engineering plant procedures?

✅ Before You Answer

• Verify whether DANGER tags are tied strictly to personnel safety or to any serious hazard, including equipment damage that could create a safety risk. • Check if "unusual caution" alone (with no clear hazard) is enough to justify a DANGER tag, or if that condition suggests a different type of tag. • Consider which choice best matches the idea: "DO NOT OPERATE" because operation could cause serious injury, death, or major damage.
