The ministry warned that homemade or faulty heaters, improperly connected chimneys and gas appliances installed by unqualified workers can pose serious risks.

Carbon monoxide is particularly dangerous because it is colorless and odorless, making it difficult to detect without appropriate safety measures.

The ministry advised residents to use only heating appliances that meet safety standards and to have gas equipment installed and inspected by qualified specialists. Chimneys and flues should also be checked regularly for blockages and soot buildup.

Residents should ensure that ventilation systems are working properly and that ventilation openings remain unobstructed. The ministry also warned against using gas stoves to heat rooms, stressing that gas appliances must be used only for their intended purpose and in accordance with safety requirements.

If heating equipment malfunctions or a gas leak is suspected, residents should take appropriate precautions and contact the relevant emergency services.

Early symptoms of carbon monoxide poisoning include headaches, dizziness, nausea and weakness. Anyone experiencing these symptoms should immediately move to fresh air, help others leave the affected area and seek emergency medical assistance.

The ministry stressed that regular equipment inspections and proper use of gas appliances can help prevent accidents during the heating season.
