Two friends from Durban recently lost their lives after suspected carbon monoxide exposure while using a gas heater during a cold night at AfrikaBurn. The tragedy has sparked conversations across South Africa about a danger many people still underestimate: carbon monoxide poisoning.

This is not just a camping risk. Carbon monoxide incidents happen in homes, guesthouses, caravans, and enclosed spaces every year— especially during winter and loadshedding, when generators and gas appliances are used more frequently.

What is carbon monoxide — and why is it so dangerous?

Carbon monoxide (CO) is a colourless, odourless gas produced when fuel burns without enough oxygen. Gas heaters, generators, gas geysers, braais, fireplaces, and gas stoves can all produce CO in enclosed or poorly ventilated spaces.

What makes carbon monoxide especially dangerous is that people often don’t realise they are being exposed. Symptoms such as headaches, dizziness, nausea, and fatigue can quickly progress to unconsciousness.

“You cannot see carbon monoxide. But you can detect it”

Why the risk increases during winter and loadshedding

As temperatures drop, more South African households rely on gas heaters and alternative power sources. At the same time, windows and doors are often kept closed to stay warm, reducing ventilation and increasing the risk of CO build-up.

Common high-risk situations include:

·        Using a gas heater inside a bedroom, tent, or caravan

·        Running a generator in a garage or enclosed area

·        Using a gas geyser without proper ventilation

·        Braais or burners in semi-enclosed outdoor spaces

·        Sleeping or spending time in any living area with fuel-burning appliances

·        Using fireplaces burning wood or coal indoors

A word from a forensic pathologist

Dr Yaseen Bismilla, a forensic pathologist, described this type of case as "classic" carbon monoxide poisoning — and stressed that it is prevalent during the winter months. He has highlighted how quickly the gas can be fatal: once inhaled in a confined space, a person can slip into a coma rapidly, without the time or energy to save themselves.

How to help prevent carbon monoxide poisoning

Prevention starts with awareness and proper ventilation, but one of the most effective safety measures is installing a carbon monoxide alarm.

A CO alarm detects dangerous levels of carbon monoxide before symptoms become severe, providing an early warning when it matters most.

A small device that can make a critical difference

Protect your home with early carbon monoxide detection. A small device can provide critical warning when every second matters.
