Only NCI Carbon Monoxide Certified Contractors may purchase this item.

The NCI yellow (Caution) tag has been created to identify newly repaired combustion equipment. They contain the right text to help prevent you from liability when dealing with a potentially lethal situation.

These 3-part (form) tags are created to allow the contractor to keep a copy of the tag for his records, provide a copy for the customer and attach the actual tag onto the designated equipment. There are locations on the tag for the technician signature, customer signature, date and time. There is a location to put your company label or stamp. Tags come complete with wire (for attaching) and are reinforced to prevent accidental removal.
