TL;DR
A red tag is the official notice an inspector or utility affixes to work or equipment found unsafe or non-compliant, ordering that it stay out of service or that construction stop until the violation is corrected. Gas utilities tag furnaces and water heaters with cracked heat exchangers or flue defects and may shut off fuel; building officials use the equivalent stop-work order on job sites.
