As temperatures drop, we rely on our heating systems to stay warm and cozy. But what happens when your heating system is deemed unsafe? That’s where red-tagging comes in—a term no homeowner wants to encounter, but one that’s crucial for safety.

Let’s break down what red-tagging means, why it happens, and how it plays a vital role in protecting your home from hazards like carbon monoxide poisoning.

What is Red-Tagging?

Red-tagging occurs when a heating technician or gas inspector identifies a fuel-burning appliance (such as a furnace, water heater, or boiler) as unsafe to operate.

A red tag is placed on the equipment to indicate that it should not be used until all necessary repairs or replacements are completed.

There are two types of red tags:
-Type A: Immediate shutdown due to critical safety hazards.
-Type B: Non-immediate issues that still require attention within a set time frame.

Why Are Appliances Red-Tagged?

Red-tagging typically occurs for the following reasons:

  1. Carbon Monoxide Risks: A cracked heat exchanger or malfunctioning burner can release carbon monoxide (CO)—a colourless, odourless gas that’s highly dangerous, even in small amounts. Symptoms of CO exposure include headaches, dizziness, and nausea, and prolonged exposure can be fatal.
  2. Old or Damaged Venting Systems: Older venting systems, especially those made from metal, may corrode or develop blockages over time, causing harmful gases to leak into your home instead of being safely vented outside.
  3. Gas Leaks or Improper Installations: Leaks in the gas line or incorrect setup of appliances can increase the risk of fire or explosion.

Why Carbon Monoxide Safety is Non-Negotiable

Carbon monoxide is known as the “silent killer” because it’s virtually undetectable without proper monitoring and often occurs due to faulty heating systems.

Preventative measures include:

  • Scheduling annual maintenance to inspect for cracks, leaks, and other safety concerns in your heating system.
  • Replacing aging or faulty appliances and ensuring proper ventilation.
  • Installing carbon monoxide detectors on every floor of your home, especially near sleeping areas.

Old Venting Systems: A Hidden Danger

If your home’s heating system is over 15 years old, its venting system might be at risk of failure. Traditional venting pipes can corrode, become disconnected, or fail to meet modern safety standards. When venting systems fail, combustion gases—including carbon monoxide—can accumulate indoors.

Upgrading to a high-efficiency heating system with direct venting can eliminate many of these risks by using sealed pipes that safely expel gases outside.

What to Do If Your Appliance is Red-Tagged

If a technician red-tags your appliance:

  1. Do not use the appliance. It’s unsafe and could pose immediate danger.
  2. Review the issue: Your technician will explain the problem and recommend solutions.
  3. Repair or Replace: Address the issue promptly. In some cases, repairing the system is enough; in others, upgrading to a newer, safer model may be the best course of action.

Stay Safe and Warm

Red-tagging might feel like an inconvenience, but it’s ultimately about keeping you and your family safe. By addressing safety concerns, maintaining your heating system, and ensuring proper venting, you can enjoy warmth and peace of mind throughout the winter season.
