On a large jobsite a scaffold tagging system is used at access points. A worker sees a YELLOW tag on a scaffold. What does this MOST likely indicate?
a.The scaffold is fully complete and safe for normal use
b.The scaffold must not be used under any circumstances
c.The scaffold is incomplete or has a specific hazard; it may be used only with additional precautions such as personal fall protection
d.The scaffold is scheduled for removal tomorrow
Giải thích
Correct: in the common green/yellow/red tag system, yellow (caution) means the scaffold is incomplete or has a special hazard and may be used only with extra precautions like a PFAS. Green means complete and safe for normal use; red (danger/do-not-use) means it must not be used. A removal schedule is not what a yellow tag communicates.
