Carbon Monoxide Danger: 5 Silent Signs of Deadly Poisoning
The carbon monoxide danger in Mauritius has become alarmingly real, with four cases of poisoning reported in just five days — including one fatality. As colder weather sets in, more households turn to gas heaters, water boilers, and indoor cooking devices, unknowingly exposing themselves to a silent, odorless, and potentially deadly threat.
This carbon monoxide danger is not new — it resurfaces every winter — but public awareness remains dangerously low. First responders and health officials are now urging residents to take immediate precautions, install detectors, and recognize the early warning signs before it’s too late.

The Silent Killer: Understanding Carbon Monoxide
What Is Carbon Monoxide?
The carbon monoxide danger stems from a gas that is invisible, odorless, and tasteless — making it impossible to detect without specialized equipment. Carbon monoxide (CO) is produced when fuels like gas, oil, wood, or charcoal do not burn completely due to poor ventilation.
According to the World Health Organization (*source here*), over 60,000 people worldwide are hospitalized annually due to accidental CO poisoning, with 4,000 deaths in the United States alone.
On our Home Safety Mauritius hub, we explore how island communities can protect themselves from environmental and household hazards like the carbon monoxide danger.
Common Sources in Mauritian Homes
The carbon monoxide danger is highest in homes using unvented gas heaters, old water heaters, or charcoal grills indoors. In recent incidents, victims were found using portable gas stoves for heating in sealed bedrooms — a deadly combination.
Other common sources include:
- Blocked flues or chimneys
- Malfunctioning water boilers
- Running vehicles in enclosed garages
- Generators used indoors during power outages
“People think it won’t happen to them,” said a firefighter in Port Louis. “But CO doesn’t warn you. It just takes you while you sleep.”
5 Silent Signs of Deadly Poisoning
Sign #1: Headache and Dizziness
One of the earliest signs of carbon monoxide danger is a persistent, unexplained headache — often described as “tight” or “pressing.” This is usually accompanied by dizziness, especially when standing up.
Because these symptoms mimic the flu or dehydration, victims often dismiss them. However, if multiple people in the same household feel the same way — especially after using a heater — CO poisoning should be suspected immediately.
“We had all been feeling off for two days,” said a survivor from Quatre Bornes. “Then my daughter passed out. That’s when we realized it wasn’t just a cold.”
Sign #2: Nausea and Vomiting
As CO levels rise, the carbon monoxide danger intensifies with nausea and vomiting. These symptoms are often mistaken for food poisoning, delaying critical action.
Unlike food poisoning, CO-related nausea does not improve with rest or medication. It worsens in the same room or at night, and improves when the person leaves the house.
“I thought I had eaten something bad,” said a patient at Victoria Hospital. “But my husband was throwing up too — in the same room.”
Sign #3: Confusion and Mental Fog
High levels of carbon monoxide interfere with oxygen delivery to the brain, leading to confusion, memory loss, and difficulty concentrating. This stage is particularly dangerous because the victim may not realize they are in danger.
In one reported case, a man wandered into the street in his pajamas, disoriented and unable to recall his name. He was later diagnosed with severe CO poisoning.
“It’s like your brain is underwater,” said a neurologist. “You know something’s wrong, but you can’t act.”
Sign #4: Shortness of Breath
Even with mild exertion, victims of carbon monoxide danger may experience shortness of breath. This occurs because CO binds to hemoglobin more effectively than oxygen, drastically reducing the blood’s oxygen-carrying capacity.
Elderly individuals and those with heart or lung conditions are at higher risk. Chest pain and fatigue are common, often misdiagnosed as asthma or heart issues.
“I couldn’t walk up the stairs without gasping,” said a 68-year-old woman. “Turns out it wasn’t my heart — it was my heater.”
Sign #5: Loss of Consciousness
The final and most critical stage of carbon monoxide danger is loss of consciousness. At this point, brain damage or death can occur within minutes.
In the fatal case reported in Curepipe, the victim was found unconscious in bed. By the time emergency services arrived, it was too late. The room had a portable gas heater running overnight with no ventilation.
“This was preventable,” said the coroner. “One detector could have saved a life.”
Prevention and Protection
Install Carbon Monoxide Detectors
The most effective way to combat carbon monoxide danger is to install CO detectors in every home. These devices sound an alarm when CO levels become dangerous — giving families time to escape.
Experts recommend placing detectors near bedrooms and on every floor. They should be tested monthly and replaced every 5–7 years.
“It’s like a fire alarm — but for invisible gas,” said a safety inspector. “And it’s just as essential.”
Ensure Proper Ventilation
The carbon monoxide danger is highest in sealed environments. Always ensure that rooms with gas appliances are well-ventilated. Open windows slightly, even in cold weather.
Never use outdoor grills, camping stoves, or generators indoors. And avoid running vehicles in garages — even with the door open.
“Ventilation is not a luxury — it’s a necessity,” said a public health officer. “Your life depends on it.”
Regular Maintenance of Appliances
Faulty or poorly maintained gas appliances are a major source of carbon monoxide danger. Have water heaters, boilers, and heating systems inspected annually by a certified technician.
Look for signs of incomplete combustion: yellow flames (should be blue), soot marks, or condensation on windows.
“A small leak today can be a tragedy tomorrow,” said a gas engineer. “Maintenance saves lives.”
Community Awareness and Government Action
Public Education Campaigns
The carbon monoxide danger requires urgent public education. Local authorities should launch island-wide campaigns — in schools, community centers, and media — to teach residents about the risks and prevention.
Posters, radio spots, and social media can all play a role. Survivors sharing their stories can have a powerful impact.
“We need to make CO as feared as fire,” said a campaign organizer. “Because it kills just as fast.”
Regulations and Safety Standards
There is growing pressure for the government to mandate CO detectors in all rental properties and new constructions. Some countries, like the UK and Canada, already have such laws.
Subsidies or free detector programs for low-income families could also save lives.
“Safety shouldn’t depend on how much you earn,” said a housing advocate. “Everyone deserves to breathe safely.”
