What are the safety precautions for working with various dusts?

Dust is the most important occupational disease hazard in China.

It can be said that dust in the industrial production process exists everywhere at any time. So, what are the safety protection measures for dust operations? Let Baibai Safety Network find out with you!

Safety protection measures for dust operations:

First, process measures.

1) Reform process equipment and process operation methods, and adopt new technologies.

2) Avoiding the selection of harmful raw materials or production process routes is the fundamental way to eliminate and reduce dust hazards.

3) The layout of process equipment and production process should be such that the main working place and the section with many operators should be located in the workshop with good ventilation and clean air, and the section with serious dust pollution should be placed on the downwind side of the perennial dominant wind direction.

2. Construction measures.

The rational design of the building can not only reduce the investment in dust prevention, but also significantly increase the dust prevention effect. It mainly includes the location, orientation, plane form and section design of the plant.

3. Wet operation.

This is a simple, cost-effective dust prevention measure that should be considered first when production and process conditions permit. For example, the dry crushing, grinding, screening and mixing of materials are changed to wet operation, and water is added to the materials during the loading and unloading and transfer of materials, which can reduce the generation and flying of dust, and wash the ground, walls, equipment covers, and building components with water in the workshop, which can effectively prevent secondary dust.

Fourth, airtight measures.

Sealing the dust source, making the production process pipelined, mechanized and automated, is an effective measure to prevent dust from escaping, and can also greatly improve the working conditions, reduce labor intensity, avoid direct contact between dust and the human body, and achieve the purpose of dust prevention.

5. Ventilation and dust removal.

This is a widely used and effective technical measure. With the improvement of the technical level in recent years, the improvement and update of ventilation and dust removal equipment in various industries, and the application of ventilation and dust removal systems are becoming more and more extensive.

6. Personal protective measures.

Personnel engaged in dust operations shall wear dust masks, dust masks, dust helmets, protective clothing and other protective equipment that meet technical requirements according to regulations, which is also the last line of defense to prevent dust from entering the human body.

It is necessary to design an event that Kurahashi is most likely to do and Yukiho is the least likely to do.

What are the safety precautions for dust operations Dust can damage the respiratory system and cause diseases mainly caused by respiratory system damage. Dust is the most important occupational disease hazard factor in our country at present, and it can be said that dust exists everywhere at any time in the process of industrial production.

What are the safety precautions for working with various dusts? Safety precautions: Be sure to wear a mask to prevent the daughter-in-law of dust and prevent the inhalation of dust.

Prevention and control measures for pneumoconiosis caused by exposure to various dusts:

1. Protective measures for the workplace: strengthen the dust protection of the storage and use of materials that are easy to dust such as cement, and no one shall dismantle them at will, and set up warning signs in the dust-prone parts.

3. Inspection measures for labor protection supplies: while inspecting the safety of the project, check the implementation of dust protection measures in the workers' workplace, and check the implementation of personal dust protection measures with low-temperature resistant gloves, not less than once a month, and guide the construction workers to reduce the operation methods and skills of dust.

2. Prevention and control measures for welders' pneumoconiosis and eye diseases

1. Workplace protection measures: provide a well-ventilated operation space for welders.

2. Personal protective measures: welders must be certified to work, wear harmful gas protective masks and eye shields during operation, put an end to illegal operations, take turns to work, and put an end to overtime work of construction operators.

3. Inspection measures: while inspecting the safety of the project, check and implement the ventilation of the workers' workplace, the wearing of personal protective equipment, the 8-hour work system, and stop illegal operations in a timely manner.

Dust operation safety protection measures description: in order to clarify the responsibilities of each person in charge, fully mobilize the enthusiasm of work, the particle size distribution of dust refers to the percentage of quality or quantity of dust of various particle sizes in the dust.

This program information is applicable to the company or organization to achieve a unified course of action between superiors and subordinates or different people through the rationalization of the plan.

Preventive measures for long-term exposure to dust: (1) Personal protection Carry out targeted personal protection according to the harm mode and injury path of dust to the human body.

Precautionary measures. 1) Personal protection.

According to the harm mode and injury path of dust to the human body, targeted personal protection is carried out. There are three ways for dust (or poisons) to harm the human body: one is inhalation, which enters the human body through the respiratory tract

second, it enters the body through the skin sweat glands, sebaceous glands, and hair follicles on the surface of the human body; The third is ingestion, which enters the body through the digestive tract.

So for the way of injury, personal protection countermeasures: one is to cut off the way of dust into the respiratory system. According to the different nature of dust, equipped with different types of dust masks, respirators, (for some toxic dust, gas masks should also be worn); The second is to block the contact of dust to **.

Wear work clothes correctly (some also need to wear overpants and hooded work clothes), helmets (the human head is the part where sweat glands, skin fat and hair follicles are concentrated), glasses, etc.: Third, it is forbidden to eat, smoke, and drink water at the dust work site.

2) Strengthen personal hygieneFirst, we should pay attention to the hygiene in the use of personal protective equipment, such as using gas masks, before use, we should understand its performance, usage and how to judge the failure and other knowledge, and replace the filter material frequently to avoid misuse or use of ineffective masks. Keep it clean and hygienic, so that it is dedicated to prevent cross-infection.

The second is to pay attention to personal hygiene, do not smoke, eat and drink in the workshop, store food and water cups, and do not heat rice and bake food in the production oven, so as not to contaminate the food into the digestive tract. Wash your hands frequently, and wash your hands before doing other things, such as smoking, eating, drinking, going to the bathroom, etc. Dust and poison workers should take a bath after work, change clean clothes and go home, change their work clothes frequently, and do not wear them home.

3) Strengthen nutrition scientifically.

On the basis of ensuring a balanced diet, according to the nature and action characteristics of the contact poisons, some special needs of nutrients should be appropriately selected to supplement, so as to enhance the systemic resistance and play the detoxification effect of some ingredients.

4) Strengthen exercise and promote metabolism.

5) No smoking, no alcohol:

Safety protection measures for dust operation 1. Types and characteristics of dust 1Types of dust According to the composition of dust, it can be divided into inorganic dust, organic dust and mixed dust; According to the particle size of the dust, it can be divided into visible dust particles with a particle size greater than 10 microns.

Legal analysis: The law stipulates that preventing dust hazards is an effective way to prevent the occurrence of pneumoconiosis. Dust work protection measures include:

1. Process measures: reform process equipment and process operation methods, and adopt new technologies. Avoid the use of hazardous raw materials or production routes.

The main working place and the section with many operators are located in the workshop where the ventilation is good and the air is relatively clean, and the section with serious dust pollution should be placed on the downwind side of the perennial dominant wind direction. 2. Wet operation: change the dry crushing, grinding, screening and mixing of materials to wet operation, add water to the materials in the process of loading and unloading and transferring materials, reduce the generation and flying of dust, and wash the ground, walls, equipment covers, and building components with water in the workshop, which can effectively prevent secondary dust.

3. Construction measures: The reasonable design of the building can significantly increase the dust-proof effect and reduce the dust-proof investment. 4. Sealing measures:

Seal the dust source, make the production process pipelined, mechanized and automated, reduce labor intensity, and avoid direct contact between dust and the human body. 5. Ventilation and dust removal: the improvement and update of ventilation and dust removal equipment in various industries, and the application of ventilation and dust removal systems are becoming more and more extensive.

6. Personal protective measures: Personnel engaged in the work shall wear dust masks, dust masks, dust helmets, protective clothing and other protective equipment that meet the technical requirements according to regulations.

Legal basis: Regulations of the People's Republic of China on the Prevention and Treatment of Pneumoconiosis

Article 6 The person in charge of an enterprise or public institution shall be directly responsible for the prevention and control of pneumoconiosis in his unit, and shall take effective measures to make the dust work site of his unit meet the national health standards.

Article 9 The system for the identification and finalization of dust-proof facilities shall be formulated by the labor department in conjunction with the health administrative department. Except for special circumstances, no enterprise or institution shall stop operation or dismantle dust-proof facilities with the approval of the competent department at a higher level.

The main technical measures to control the generation of dust are:

a Reduce the dust diffusion range and eliminate dust.

b. Inerting protection for production equipment that produces combustible dust.

c Control the fire source and increase humidity appropriately.

d Technical measures such as explosion suppression devices can also be adopted.

The safety technical measures to prevent dust focus on four aspects: 1, the production device itself 2, the production environment 3, the elimination of static electricity 4, and the standard operating procedures.

Legal Analysis: Generally speaking, solid particles are produced during the production process and can float in the air of the production environment for a long time. The harm of productive dust to the human body is many, but the most prominent harm is manifested in the lungs, due to the different properties and chemical composition of dust, the harm to the lungs is very different, according to the performance after damage, the lung diseases caused by dust can be divided into three situations.

Legal basis: Constitution of the People's Republic of China Article 53 Citizens of the People's Republic of China must abide by the Constitution and laws, keep state secrets, protect public property, abide by labor discipline, abide by public order, and respect social morality.

1.Wear a mask: If the lungs inhale dust for a long time, it may lead to pneumoconiosis, so it is recommended to wear a mask when going out, you can wear KN95, KN100, KN90 and other types of masks, which can prevent most dust hazards.

2.Avoid dusty environments: It is recommended to avoid stone factories, timber factories, cement factories, commercial mixing plants or dusty environments, which can prevent dust hazards to a certain extent.

3.Regular examination: It is recommended that patients go to the hospital regularly for chest CT examination, which can diagnose whether there are lesions in the organs and tissues of the respiratory system, so as to prevent dust hazards.
