In most people's understanding, range hoods are only used when cooking. This is because people think that only oil fumes are generated when cooking, and range hoods are only used to remove oil fumes. Therefore, many housewives do not turn on the range hood when cooking, boiling water, or lighting gas, and they also believe that keeping it on consumes electricity.
The truth is often not felt. In many cases, people unknowingly harm their health due to excessive reliance on intuition. Research has found that when natural gas, coke ovens, and liquefied petroleum gas are used for combustion in ordinary households, each burner produces 1000 milligrams of carbon monoxide in one hour. In addition, it can also generate harmful substances such as nitrogen oxides and dust. When boiling water or cooking at home, ventilation is often neglected. If two burners are burning simultaneously at this time, the carbon monoxide concentration in the kitchen will reach 100 milligrams per cubic meter after half an hour, which is 10 times the national standard for carbon monoxide concentration.
Medical research has proven that carbon monoxide is more likely to bind with hemoglobin in human blood than oxygen. Once carbon monoxide is inhaled into the body, it replaces the oxygen in hemoglobin, causing the blood to lose its ability to transport oxygen and leading to carbon monoxide poisoning. It has been measured that when the concentration of carbon monoxide in the air reaches 0.04%, people will experience symptoms such as headaches, weakness, dizziness, blurred vision, nausea, vomiting, and collapse. If a person stays indoors with a carbon monoxide concentration of 1.28% for 1-3 minutes, it will result in death. Therefore, not using a range hood when using a gas stove for boiling water or cooking can cause significant harm to the body due to the carbon monoxide gas produced.
The editor kindly reminds you:
The working principle of a range hood is to use supplementary fresh air to create negative pressure within a certain space above the stove, thereby achieving the effect of exhaust. Therefore, when using a range hood, you must open the door or window on the opposite side of the kitchen to supply air, and it is best to open the door leading to the outside to introduce outdoor air.
