Carbon monoxide poisoning from a running engine in a poorly ventilated garage is a real danger for drivers. Medical professionals warn that even short exposure can have serious consequences. A physician from the Medsi clinic in Krasnogorsk emphasizes this risk in public discussions, noting that many people underestimate how quickly carbon monoxide can affect health when the space lacks proper airflow.
Carbon monoxide is a colorless, odorless gas that enters the body through inhalation. It binds with hemoglobin in red blood cells to form carboxyhemoglobin, which reduces the blood’s ability to carry oxygen to tissues. Even very small amounts, if not addressed promptly, can lead to severe symptoms and, in some cases, death when exposure is prolonged. The potential for harm increases with higher concentrations of the gas and longer exposure times.
Clinical signs vary with the level of exposure. Early symptoms typically include headaches, a sense of pressure in the temples, dizziness, and nausea that is not related to meals. Some individuals may also experience visual disturbances or a feeling of confusion as the brain receives less oxygen. These signs can be misinterpreted or dismissed, especially when they appear after routine tasks or short periods in a garage with a running engine.
As poisoning progresses, individuals may become sleepy or apathetic. Tinnitus may worsen, headaches intensify, and breathing can become rapid and shallow. Affected people often stay aware of their surroundings but feel unable to think clearly. If intervention is delayed, breathing can become irregular and the heartbeat may weaken, potentially leading to a fatal outcome.
Longer-term or severe exposure carries risks beyond the immediate crisis. Some people may experience lingering memory problems, difficulty concentrating, and a decline in cognitive function long after the episode. These delayed effects reflect the lasting impact of brain tissue receiving insufficient oxygen during exposure and highlight the importance of timely medical assessment after suspected poisoning.
Prevention hinges on ensuring adequate ventilation and avoiding running engines in enclosed spaces. If a vehicle must be started indoors for any reason, it should only occur in a well-ventilated area or outdoors. Installing and maintaining carbon monoxide detectors in garages, attics, and other enclosed spaces can provide early warning. Regular checks of exhaust systems and ensuring there are no blockages or leaks further reduce risk. Anyone who experiences sudden, unexplained headaches or dizziness after being in a garage with an engine running should seek medical evaluation promptly to rule out poisoning. Early treatment improves outcomes and reduces the likelihood of complications later on.
Authorities and health professionals also remind the public about the dangers of inhaling antifreeze vapors and other automotive chemicals, which can compound health risks when exposure is not properly managed. These warnings underscore the broader principle: indoor air safety matters for drivers, families, and workers alike. Attribution: Medsi Krasnogorsk interview and medical guidance
