Can plastic factory mixture get dust disease, and the harm of plastic dust to the body

According to the "Industrial Classification of the National Economy (GB T 4754-2017)", the production activities of various products with synthetic resin (polymer compounds) as the main raw material and processed and molded by extrusion, injection molding, blow molding, calendering, lamination and other processes belong to the plastic products industry. Therefore, for enterprises that do not use vinyl chloride monomer to process polyvinyl chloride, and only use polyvinyl chloride resin for injection molding and extrusion processing, injection molding and extrusion exhaust gas do not implement the "Synthetic Resin Industrial Pollutant Emission Standard" (GB 31572-2015), "Caustic Soda, Polyvinyl Chloride Industrial Pollutant Emission Standard" (GB 15581-2016), implement the "Comprehensive Emission Standard for Air Pollutants" (GB 16297-1996), and more stringent local emission standards have been formulated. Implemented according to local standards. Hefei Jietong Environmental Technology Co., Ltd. is a company dedicated to environmental protection

Although there is no plastic pneumoconiosis among the 12 types of pneumoconiosis, this environmental dust can cause inflammation of the respiratory system and foreign body deposition in the lungs, which is also harmful to the body. It is recommended to wear a compound dust mask.

According to the GB2626-2006 standard for dust masks, the protection levels of filter cotton are KN100, KN95 and KN90 respectively. Among them, the KN100 level can protect against ultra-fine dust. The protection rate of KN95 is more than 95%, and KN90 is more than 90%.

If the dust concentration in the working environment is high or toxic and harmful, it is recommended to choose a KN100 professional dust mask.

The scientific selection of dust masks certified by the GB2626-2006 standard helps to prevent lung damage.

1. Choose a duplex half mask type. Disposable masks are not suitable for long-term 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 covering the mouth and nose, covering the mouth, nose and jaw, and it is recommended to use the latter, and this design is used in international high-comfort masks.

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.

Inorganic dust, such as silica dust (quartz dust), asbestos dust, coal dust, metal dust, cement dust, abrasive dust, etc.;

Organic dust, such as cotton dust, hemp dust, bagasse dust, tea dust, feather dust, fur dust, plastic dust, etc. From the perspective of dust classification, female workers have more opportunities to come into contact with organic dust. However, female workers also account for a large proportion of inorganic dust operations such as asbestos dust, cement dust, and abrasive dust.

Except for the toxic effect of metal dust, there is not much gender difference in the harm of other kinds of dust to the human body. However, the harm of inorganic dust and organic dust to the human body is very different.

1) Inorganic dust. Represented by silica dust, the harm to the human body is mainly manifested in the fibrosis of the lungs, the alveoli are filled, and the ventilation function is impaired, so the X-ray chest radiograph is significantly different from that of normal people, and there are symptoms such as cough, chest tightness, and shortness of breath. There are few female workers engaged in silica dust operations, but in recent years, there are also many female workers in some stone and stone powder processing workshops in township enterprises.

Asbestos dust in inorganic dust is not uncommon for female workers to come into contact with, mainly for the processing or use of asbestos cloth, asbestos rope and asbestos thread. Asbestosis caused by stone dust is similar to silicosis caused by silica dust, but its onset is slightly slower. In the cement production and cement products processing industry, the production and use of grinding wheels in the industry, female cement dust operators and grinding wheel dust operators account for a large proportion, but these two types of dust have less harmful effects.

2) Organic dust. Female contact is more common. Represented by cotton dust, the harm to the human body is not like silica dust or asbestos dust can cause pulmonary fibrosis, but to make people get a disease called "cotton dust syndrome", that is, after a day of rest and then go to work, there will be chest tightness, chest tightness, a little wheezing or combined cough, the first day is heavier, but gradually reduced in the next few days, and long-term reversal can cause chronic bronchitis.

It is thought that this is due to an allergy to cotton dust. It can also cause a kind of "textile fever", which mainly occurs in people who come into contact with cotton dust for the first time, and it starts like a cold, and it gets better in 2 to 3 days, but it will attack later. These two diseases caused by cotton dust can also occur in operations such as hemp dust, tea dust, feather dust, and fur dust.

It takes more than 200 years for plastic to rot when buried in the ground, and it seriously damages the environment and pollutes the soil, posing a threat to animal survival.

When the plastic is broken, it will be polluted by dust and mud attached to its surface, and it may also produce odors due to the liquid or other substances it has been exposed to. The best thing is to do a targeted dust removal action on the dust production point to prevent the dust from flying.

The harm of dust to the human body can cause different lesions according to its physical and chemical properties and the amount of dust entering the human body. Such as respiratory system diseases, local effects, toxic effects, etc.

To prevent dust hazards to human health, the first step is to eliminate or reduce the source of occurrence, which is the most fundamental measure. The second is to reduce the concentration of dust in the air. Finally, it is necessary to reduce the chance of dust entering the human body, as well as to reduce the harm of dust.

Health care measures are the last link in prevention and, although adjunctive, still have an important place.

1) Personal protection and personal hygiene, for operations where the dust concentration does not reach the allowable concentration standard for a while, wearing a suitable dust mask has become an important measure. Dust masks should have high dust filtration rate, air permeability, and light weight, so as not to affect workers' vision and operation. Carrying out physical exercise and paying attention to nutrition have certain significance for extending the range of physique and improving resistance.

In addition, you should pay attention to personal hygiene habits, do not smoke, abide by dust-proof operating procedures, and strictly implement the system of not wearing dust-proof masks and not working on duty.

2) Pre-employment and regular physical examination, for new workers engaged in dust operations, health examinations must be carried out, the purpose is mainly to find contraindications to dust operations and as health information. The purpose of regular physical examination is to detect the damage to health caused by dust at an early stage, and to transfer it in time if there is a disease that is not suitable for dust work.

3) Appropriate arrangements can be made to protect patients with pneumoconiosis, enjoy the due treatment allowed by national policies, and their working ability should be appraised and properly placed.
