冬季做饭这个习惯，或引发一氧化碳中毒！这4点尤其要注意

Core Viewpoint - The article highlights the dangers of cooking in a closed kitchen with the exhaust fan on, which can lead to a hazardous environment due to the accumulation of carbon monoxide and depletion of oxygen levels [1][3]. Group 1: Risks of Cooking in a Closed Environment - Closing windows and turning on the exhaust fan can create a "negative pressure" environment in the kitchen, leading to harmful gases being drawn back into the room [3]. - An experiment showed that carbon monoxide levels rose from 0 ppm to 194 ppm within minutes, while oxygen levels dropped from 20.6% to below 17.1% [3]. Group 2: Safety Recommendations - It is essential to keep windows slightly open (5-10 cm) while cooking to ensure continuous airflow and prevent negative pressure [5]. - Regular inspections of gas appliances and ventilation systems are recommended to ensure safety [6]. - Installing carbon monoxide detectors in the kitchen and adjacent living areas is advised for 24-hour monitoring [6]. - Avoid adding non-standard attachments to gas stoves, as they can obstruct airflow and increase carbon monoxide emissions [7].
