A red tag means your equipment is unsafe.

A red tag, also known as a product warning tag, may be placed on a gas appliance by a licensed technician to indicate that it is no longer safe to operate and needs to be repaired or replaced. In certain instances, the technician is required by law to turn off the gas as a safety measure.

There are two types of red tags: “A” tags are used on immediate hazards and “B” tags indicate unsafe conditions. In both cases your business depends on fast resolution – call 1 855-321-1508 and we will get you back up and running quickly.

Why have I received a warning tag?

Warning tags are issued on any appliance or piping system that uses natural gas when a licensed gas technician has identified a hazardous issue. For example, if a defective heat exchanger is identified it can release carbon monoxide, an odourless and colourless gas, which can cause serious health problems if undetected. Carbon monoxide is harmful because it can rapidly accumulate in the blood, reducing the blood's ability to carry oxygen.

If carbon monoxide is leaking from a cracked heat exchanger, there is a chance of it mixing with the air that is generated by the furnace and pushed through the vents. To prevent this danger, a red tag is applied to your furnace, your local utility is notified, and your natural gas is turned off.

Types of warning tags

Type A: If a licensed technician has identified an immediate danger, for example a severe carbon monoxide leak, a Type A red tag will be issued and your natural gas will be turned off right away.

Type B: If the equipment does not pose an immediate danger, a Type B warning tag will be applied to the equipment and the local utility notified. This tag gives you a specified period of time to have the equipment repaired or replaced. If corrective action is not taken within the stipulated timeline, your natural gas will be turned off by the local utility.
