Unseen Menace: Gas Safe Guardians Against CO
You can’t see it, smell it, or taste it, but carbon monoxide (CO) is a deadly gas that claims lives every year. Often called “the silent killer,” CO is a byproduct of incomplete combustion from common household appliances like boilers, gas fires, and cookers. The good news? Carbon monoxide poisoning is almost entirely preventable.
What Makes Carbon Monoxide So Dangerous?
When inhaled, CO starves your vital organs of oxygen. Symptoms are often flu-like and easily missed: headaches, dizziness, nausea, fatigue, and shortness of breath. Prolonged exposure can lead to serious health issues or death.

Common sources of CO in the home include:
- Faulty or poorly maintained gas boilers and furnaces.
- Improperly installed gas fires and cookers.
- Blocked chimneys or flues.
- Portable generators used indoors.
Your Essential Defense: A Gas Safe Registered Engineer
When it comes to gas appliances, relying on qualified professionals is non-negotiable. In the UK, that means a Gas Safe registered engineer. They are your best defense against CO poisoning because they provide:
- Expertise and Training: Gas Safe engineers are legally qualified and rigorously trained to work safely with gas appliances.
- Thorough Appliance Servicing: Annual servicing ensures your gas appliances operate efficiently and safely, identifying potential CO risks.
- Proper Installation: Correct installation prevents CO leaks from the outset.
- Flue and Chimney Checks: They inspect crucial ventilation systems to ensure CO escapes safely.
Simple Steps to Prevent CO Poisoning
Beyond professional help, take these vital steps:
- Install Audible Carbon Monoxide Alarms: Place alarms on every level of your home, especially near sleeping areas, and test them regularly.
- Get Appliances Serviced Annually: Schedule yearly checks for all gas appliances with a Gas Safe registered engineer.
- Ensure Proper Ventilation: Never block air vents or flues.
- Know the Symptoms: Educate your family. If you suspect CO, get fresh air immediately and call 999.
- Check for Warning Signs: Look for soot stains, a yellow/orange flame (should be blue), or increased condensation around appliances.
