Most of the rescue sites are dusty, and the open-air environment is a non-chemical plant, and there are few toxic and harmful gases. Therefore, dust masks are the right choice. Gauze masks are not recommended, at least disposable masks certified by GB2626-2006 are used.
Working in a dusty environment, it is recommended to do a good job of respiratory protection for your health. Choose a dust mask scientifically, choose a good mask with good protective effect, smooth breathing, and economical use. Helps prevent lung damage from occurring.
The way to clean the dust: now masks must implement the GB2626-2006 standard. The grades of dust masks are divided into three grades: KN100, KN95, and KN90.
Among them, KN100 can achieve nearly 100% (more) protection effect against ultrafine dust. If the granularity is large, KN95 grade can be selected.
The protective effect of dust masks depends on 2 aspects. One is the filtration efficiency of the filter cotton. The second is how tightly the mask is combined with the face.
Therefore, masks must be divided into large and small sizes, and the fit effect of masks and faces varies from person to person.
The way to clean dust: the scientific selection of dust masks certified by GB2626-2006 standards can help prevent lung damage.
1. Choose a duplex half mask type. Disposable masks are not suitable for long-term or occupational protection due to their high air leakage rate.
2. Choose KN100 dustproof filter cotton for use. A low rate of protection will lead to physical injury.
3. It is more comfortable to choose silicone material. It is suitable for long-term wear and is not easy to cause allergic reactions. Masks with high rigidity are prone to facial indentation.
4. Masks are divided into large and small sizes, which is extremely important. Don't buy masks that are called generic models. Prone to air leakage.
5. There are two types of masks that cover the mouth and nose, covering the mouth, nose and chin, and it is recommended to use the latter, which is relatively comfortable.
6. It is recommended to choose a breathing mask. Some masks are designed with double filters, and the filters are double-sided, so that the masks are relatively easy to breathe.

1. Shut down chemical plants that pollute the environment;
2. Plant more trees;

1. For the treatment of the number of industrial unorganized dust, it is necessary to take the source dust suppression as the guide, and at the same time combine the emission control technology to achieve comprehensive treatment. With biological nanofilm dust suppression technology as the core, it assists other dust removal technologies to suppress organized and unorganized dust emissions in the industrial field to the greatest extent, reduce dust emissions in the industrial field, and improve the atmospheric environment in an all-round way.
2. Strengthen the supervision and supervision of civilized construction at construction sites, and let all construction sites take effective measures to prevent dust.
3. Coal-fired heating and thermal power stations should be used as soon as possible to use cleaner clean energy such as natural gas, hydropower, and nuclear power generation.
4. Improve the quality of gasoline and diesel, and implement stricter automobile exhaust emission standards.
5. Industrial spraying should be set up in a closed place for spraying as much as possible, and after the spraying is completed, the spraying room will be discharged into the air after treatment.
6. Reduce the production emissions of cement plants and other factories, and if conditions permit, treat the exhaust gas before discharge and then discharge it into the air.
7. To eliminate haze weather, it is necessary to rely on the introduction of governance policies with clear guidance, appropriate rewards and punishments, and ensure that the policies are implemented, but also rely on enterprises to strengthen energy conservation and emission reduction, technological transformation, and reduce emission reduction to a minimum. But in the face of raging smog, there are no bystanders, and there are no mere critics, because no one is immune. In addition to criticism and supervision, everyone should take practical actions and make positive efforts to be an actor and promoter of eliminating haze weather.
8. Car owners can choose to choose to travel and drive as little as possible. With the rapid growth of motor vehicle ownership, vehicle exhaust emissions have become an important factor causing smog. When it's convenient for you, try to use public transportation to get around. Abandon the convenience of the moment and change the blue sky and white clouds.
9. Fewer fireworks and firecrackers on festive holidays. During the Spring Festival this year, many places exploded in an instant due to the excessive concentration of fireworks and firecrackers on Chinese New Year's Eve. There is less waste of resources in home life, electrical appliances that are not used by people should be turned off, socket display lights should not be long lights, and the temperature of the empty line should not be too low in summer, etc.
Between the raised hands, bring green.
In other words, the first important thing is not to trace the source, but the following three questions: First, is the city's information release mechanism "to act when it is time to act"? Smog lingers, and environmental problems can turn into public health events at any time. >>>More
Haze is caused by the excessive content of particulate matter (particulate matter) in the air, and most of the residues emitted through combustion in the process of daily power generation, industrial production, automobile exhaust emissions, etc., mostly contain fine particulate matter, which is a general term for solid particles or droplets with a diameter of less than or equal to microns in the air, which can enter the lungs with breathing, so it is also called particulate matter that can enter the lungs.
Everyone should go out less, wear masks, and try not to open windows.
Drink more chrysanthemum wolfberry tea Chrysanthemum wolfberry tea has the effect of dispersing wind and clearing heat, calming the liver and brightening the purpose, everyone knows that the computer family should drink more chrysanthemum wolfberry, but they don't know that drinking chrysanthemum wolfberry tea on hazy days also has the effect of moisturizing and nourishing the lungs. In haze days, dust, sulfuric acid, nitric acid and other particles in the air will be inhaled into people's lungs, clearing the lungs and detoxifying is the key to health in haze days.
The culprits of air pollution in the car include particles, formaldehyde, benzene, TVOC (total volatile organic compounds), mainly in the plastic parts, carpets, top felt, seats and other decorations used in the glue, and some harmful gases are used in second-hand smoke, smoke, car exhaust, food debris, etc. These pollutants are harmful to **, respiration, blood, and cardiovascular, and can cause dizziness, chest tightness, respiratory tract inflammation, and even carcinogenic in severe cases. <> >>>More
