The civilization and health of the city is closely related to the civilization of the citizens. Take smoking as an example. It is not only the social morality that every smoker should follow, but also the bounden responsibility of smokers to adhere to civilized smoking and create a comfortable, harmonious and good social public environment.
Small cigarette butts, casually throw, seems to be "small", but do you know the harm of casually throw cigarette butts? Although the cigarette end is small, the temperature of Mars is about 200 degrees, the surface temperature of cigarette end is about 250 degrees, and the center temperature of cigarette end is as high as 700 to 800 degrees! After the cigarette ends are discarded, the surface temperature is 550 ~ 600 ℃ and the center temperature is about 830 ℃, which is significantly higher than the ignition point of many other combustible materials. After the cigarette ends are discarded, they can continue to burn for one to four minutes, and it is easy to cause fire when they encounter combustible materials. Therefore, after smoking, the cigarette end must be completely extinguished. After the cigarette end is completely extinguished, it can be thrown into the ashtray, metal, glass and other non flammable appliances. It is strictly forbidden to throw cigarette ends randomly, so as to truly achieve "cigarette end does not fall to the ground".
Smoking is harmful to health, smokers should pay attention to smoking occasions, for their own sake, but also for others, to be civilized citizens.
When smoking, only about 10% of the cigarette smoke is inhaled by smokers, and the rest is scattered in the surrounding environment. With the increase of the number of smokers and the extension of smoking time, the concentration of harmful substances in the air continues to increase. Non smokers are forced to inhale this kind of air, but also inhale the harmful substances in the smoke. Long term passive inhalation of second-hand smoke, non-smokers will increase the risk of lung cancer. According to relevant studies, more than half of the non-smokers who die of lung cancer are passive smokers. In public places, if more people smoke, resulting in dense smoke environment, more victims, the consequences are more serious.
In order to create a comfortable, harmonious and good social public environment for themselves and others, the majority of smokers must achieve civilized smoking. In places with the words "no smoking" or "no smoking room", rooms with air conditioning, rooms without ashtrays and public places, smoking should be prohibited and social morality should be observed.
Be a civilized smoker, do not smoke in crowded areas, do not smoke in front of women and children, do not smoke in dangerous places, do not smoke in confined spaces.
