Let’s Talk Red Tags

What does a red tag on a gas appliance mean?

A red tag gets attached to a gas appliance by a licensed technician when it's considered unsafe for use.  This may mean it either needs repairs or replacement. If the problem is serious enough, the gas supply must be turned off as a precautionary step to ensure the safety of you and your family.  The technician is legally bound to do so as per code.

What are the types of Red Tags?

Type A Unacceptable Condition - Immediate Hazard:  If a licensed technician has identified an "immediate danger", for example, a severe carbon monoxide leak, gas leak etc., the appliance(s) in question will receive a Type A Red Tag and your natural gas / propane will be immediately turned off.

Type B Unacceptable Condition - No Immediate Hazard: If the appliance(s) does not pose an immediate danger to the homeowner, a Type B Warning Tag will be applied to the appliance(s) in question and the local utility will be notified (e.g. Enbridge Gas or Propane Supplier).  This tag gives you a 30-90 day deadline to have the equipment repaired or replaced.  If corrective action is not taken by the deadline, your natural gas / propane will be turned off by the local utility.  In the case of propane, your supply will be disconnected or the vendor will stop supplying you with propane.

Is it safe to use other gas appliances in my home if one has a red tag?

Although it is upsetting and frustrating to receive a Red Tag, it is important to try to keep a cool head.  Remember it is not the technician’s fault, he/she is only doing what needs to be done as per code that they are legally bound to.  Remaining calm will allow you to ask the technician if it is possible to use the other appliances or does the infraction affect all of them.  If you are unable to pose the question, then it is recommended to refrain from using any gas appliances in your home if one of them has received a red tag. The other appliances may appear to be functioning normally, but there may be underlying infractions that could cause great risks to the safety of you and your family.  You should have all of the gas appliances inspected by a professional before using them again.
