Carbon Monoxide – The Silent Killer 

Most discussions concerning fire safety are centred around prevention and how to stay safe in the event of a blaze. Whilst these are important considerations, there’s another deadly threat which often goes unnoticed: carbon monoxide (CO). Commonly known as the ‘silent killer, carbon monoxide is a colourless, odourless gas which can be deadly when undetected.  In this blog post, Astute Fire will share some insight into the dangers of carbon monoxide, how it can enter your building, and most importantly, how to protect your colleagues and loved ones from this silent threat.  

Understanding Carbon Monoxide 

Carbon monoxide is a toxic gas, and it can build up rapidly in situations where carbon-containing fuels like wood, gasoline, propane and natural gas don’t burn completely. One of the most common reasons for carbon monoxide build up is incorrect installation, neglectful maintenance or poor ventilation of appliances such as stoves, fireplaces and hot water heaters.  

Whilst carbon monoxide does not pose much of a risk in well ventilated areas, it presents a serious problem when it accumulates in enclosed spaces. CO molecules attach to the haemoglobin within the red blood cells of humans, displacing oxygen and preventing the body from getting the oxygen it needs to function properly. This eventually leads to organ failure and death.  

Common Sources of Carbon Monoxide 

Carbon monoxide can enter a home or business premises from various sources. Being aware of potential sources is the first step in safeguarding your colleagues and loved ones against this serious threat. 

  1. Heating Systems – space heaters, furnaces, boilers and other heaters which utilise fuel have the potential to produce carbon monoxide if they experience a malfunction or lack adequate venting.  
  2. Fireplaces and Wood Stoves – incomplete combustion occurs when burning wood, which may release carbon monoxide into your building. 
  3. Gas Stoves and Ovens – Poor installation or malfunctioning gas appliances may produce CO.  
  4. Vehicles – An idling engine within an attached garage can release vast amounts of carbon monoxide into your home.  
  5. Generators and Barbecues – Using generators or barbecues in enclosed spaces can lead to dangerous CO levels.  

Symptoms of Carbon Monoxide Poisoning 

With no noticeable odours or clearly visible symptoms, recognising the signs of carbon monoxide poisoning can prove a challenge to bystanders. If you or another occupant of the building experience any of the following symptoms, this could be an indicator for CO exposure. 

  • Headache 
  • Nausea or vomiting 
  • Dizziness or light-headedness 
  • Confusion or impaired judgement 
  • Weakness or fatigue 
  • Shortness of breath 
  • Loss of consciousness 

If multiple occupants complain of these symptoms, this is a cause for concern. It is important to evacuate the building immediately. 

Protecting Occupants against Carbon Monoxide 

With the dangers of carbon monoxide now clear, here’s what you can do to protect building occupants. 

  1. Install Carbon Monoxide Detectors – many modern smoke alarms also function as carbon monoxide detectors. These devices should be placed on every level of the building, particularly near bedrooms and other frequently used rooms. These detectors should be tested monthly.  
  2. Regular Inspections – your appliances and fire safety equipment should be inspected by a qualified technician on an annual basis.  
  3. Proper Ventilation – keep your home or business well ventilated. Open windows to allow plenty of fresh air. 
  4. No Indoor Generator Use – never use a generator indoors. These should only be used outdoors, well away from open doors or windows.  
  5. Education – teach others about the dangers of carbon monoxide poisoning, including common symptoms to be aware of.
