When installing CAUTION tags when performing a tag-out and lock-out procedure in preparation for accomplishing maintenance, what is the color of these tags?

Correct Answer: Option B — Yellow

Caution tags are color-coded yellow to indicate that equipment is in an abnormal condition or that special instructions must be followed before operation. This distinguishes them from red Danger tags, which strictly prohibit operation, ensuring clear communication of operational status to all engineering personnel during maintenance activities.
