Why is smoking forbidden in the elevator?

Smoking in the elevator, if the cigarette end in your hand accidentally falls into the gap between the elevator door and the floor, is likely to cause a fire. When the elevator is running, some parts may generate high temperature due to friction. At this time, if the unlit cigarette ends fall, the consequences will be unimaginable.

In addition, the smoke generated by smoking in the elevator may trigger the smoke alarm and cause the elevator to stop suddenly. In a word, smoking in the elevator is a very unsafe practice.

The harm of smoking

1. Influence on cardiovascular and cerebrovascular diseases: Smoking is an important inducement of cardiovascular and cerebrovascular diseases such as hypertension and coronary heart disease. Statistics show that 75% of patients with coronary heart disease and hypertension have a history of smoking.

Nicotine and carbon monoxide in smoke are considered as harmful substances. Smoking can damage vascular endothelial cells, increase cholesterol, cause peripheral blood vessels and coronary arteries to contract, and cause myocardial hypoxia. Therefore, smokers with cardiovascular diseases are more prone to arrhythmia and the risk of sudden death is increased.

2. Impact on respiratory tract: Smoking is one of the main causes of chronic bronchitis, emphysema and chronic airway obstruction. The probability of smokers suffering from chronic bronchitis is 2-4 times higher than that of non-smokers. Patients often have chronic cough, expectoration and dyspnea during activities. Even young asymptomatic smokers have slight lung dysfunction.
