A tragic carbon monoxide poisoning incident at Mahean-Ablekuma has resulted in the deaths of three people, including 19-year-old SHS graduate Florence Naa Kwarley. The victims were found in a hardened state on Wednesday, May 6, 2026, after inhaling fumes from a generator placed in a locked corridor during a power outage.
This heartbreaking event highlights the extreme danger of operating internal combustion engines in enclosed or semi-enclosed spaces. While the carpenter, Jonas Ofosu Yeboah, likely placed the generator in the corridor to prevent theft or protect it from weather, the lack of ventilation turned the home into a lethal gas chamber. Carbon monoxide is often called the “silent killer” because it is colorless, odorless, and tasteless, making it impossible to detect without specialized equipment.
As authorities investigate the Ablekuma incident, it serves as a grim reminder for residents across Accra and beyond. Using a generator indoors is never safe, regardless of whether windows are open or if the unit is placed in a hallway. The physics of gas accumulation ensures that toxic levels can be reached in minutes, leading to unconsciousness and death before victims even realize they are in danger.
What caused the deaths at Mahean-Ablekuma?
The primary cause of death in the Ablekuma incident is suspected to be carbon monoxide (CO) poisoning originating from a portable generator. The generator was reportedly left running in a locked corridor while the victims slept, allowing toxic exhaust to seep into the living quarters and displace the oxygen in their blood.
When a generator burns fuel, it releases CO, a gas that binds to hemoglobin in the human body 200 times more effectively than oxygen. This prevents the heart and brain from receiving the oxygen they need to function. In the case of the three victims in Mahean, the “hardened state” in which they were found suggests they had been deceased for several hours, likely passing away in their sleep without ever waking up to seek help.
This specific tragedy involved a 70-year-old carpenter and two young adults, showing that CO poisoning does not discriminate by age or health status. If a generator is not placed at least 20 feet away from a home with the exhaust pointed away from windows and doors, the risk of a fatal incident remains extremely high during any power outage.
“It is heartbreaking. My brother was always careful, but that night he placed the generator in the corridor to deal with the power outage. We never imagined it would end like this,” she said.
The Amasaman Divisional Police Command has confirmed that investigations into the incident are ongoing.
Why is carbon monoxide called the silent killer?
Carbon monoxide earns its nickname because it is completely undetectable to human senses; you cannot see it, smell it, or taste it. Unlike smoke from a fire which triggers a cough reflex or stings the eyes, CO fumes can fill a room and overwhelm a person’s nervous system without providing any physical warning signs.
For the victims at Ablekuma, the environment likely seemed perfectly normal until they drifted into a deep, permanent sleep. Early symptoms of CO poisoning, such as “flu-like” headaches, dizziness, or nausea, are often dismissed or unnoticed if the person is already asleep. This is why the use of CO detectors is a standard safety recommendation in many developed nations, though they are less common in residential areas like Mahean.
Logic tells us that if we can’t smell it, it isn’t there. However, generator exhaust is much more concentrated than car exhaust, and the CO levels can rise to lethal parts-per-million (ppm) levels very quickly in small hallways or corridors. Even a few minutes of exposure to high concentrations can be fatal.
Factual Insights into Carbon Monoxide and Generator Safety:
- Lethal Concentration: Carbon monoxide can reach a lethal concentration in a small room in less than 10 minutes if a small 5kW generator is running indoors.
- The 20-Foot Rule: Safety experts and the CDC recommend that generators should be kept at least 20 feet (6 meters) away from any door, window, or vent.
- Hemoglobin Binding: CO is dangerous because it displaces oxygen in the blood, creating carboxyhemoglobin which effectively “starves” the brain of air.
- Hardening of Bodies: The discovery of bodies in a “hardened state” usually indicates rigor mortis has fully set in, which typically occurs 12 to 18 hours after death.
- Annual Mortality: According to the CDC, over 400 Americans die annually from accidental CO poisoning, and the rates are significantly higher in regions with frequent power outages and low safety awareness.
- Silent Symptoms: High levels of CO can cause a victim to lose consciousness before they ever experience the “warning” symptoms of a headache or dizziness.
Is it safe to run a generator in a corridor with windows open?
No, it is never safe to run a generator in a corridor, garage, or any semi-enclosed space, even if the windows are open or fans are running. The Ablekuma tragedy occurred in a “locked corridor,” which essentially trapped the gas and funneled it directly into the adjacent rooms where the victims were sleeping.
Open windows do not provide enough cross-ventilation to clear the massive volume of CO produced by a portable engine. In fact, an open window near a generator can actually act as a vacuum, sucking the toxic fumes directly into the house rather than letting them escape. The only safe place for a running generator is outdoors, in an open-air environment with plenty of space for exhaust to dissipate.
It is a common mistake to think that as long as there is an “opening,” the air will stay fresh. The reality is that CO is slightly lighter than air and can linger in pockets, eventually building up to a saturation point that makes a single breath of air toxic.
What should you do if you suspect carbon monoxide poisoning?
If you suspect CO poisoning, you must move to fresh air immediately and call for emergency medical assistance. If you are indoors and start feeling suddenly dizzy, weak, or confused while a generator or charcoal grill is nearby, do not stop to open windows just get out of the building as fast as possible.
In many cases, victims realize something is wrong but try to turn off the generator or investigate the noise before leaving. This delay is often fatal, as the physical exertion speeds up the absorption of the gas into the bloodstream. At Ablekuma, the victims were found long after it was too late to intervene, highlighting the importance of prevention over reaction.

Medical treatment for survivors usually involves high-flow oxygen or a hyperbaric chamber to force the carbon monoxide out of the hemoglobin. However, the best defense is a $20 carbon monoxide detector, which sounds a loud alarm as soon as gas levels become unsafe, providing the “voice” that this silent killer lacks.
Learning from the Ablekuma Tragedy
The loss of Florence Naa Kwarley and her companions is a devastating blow to the Mahean-Ablekuma community, but their story must lead to better safety habits. Power outages are a reality for many, but a generator should never be valued more than the lives of those it is intended to serve. Keeping equipment outside and away from living spaces is the only way to ensure a “light” doesn’t lead to a tragedy.
As we mourn these three individuals, let us spread the word that a “locked corridor” is a coffin when a generator is involved. Education is the most effective tool we have to prevent another family from discovering their loved ones in a hardened state after a simple night of seeking power.

If your neighbor was running a generator on their balcony or in a hallway tonight, would you feel comfortable explaining the “silent killer” to them, or would you assume they already know the risks?
