What are the preventive controls for productive toxicants?

Preventive measures are:

1. Closed ventilation and detoxification;

2. Local exhaust hood (closed hood with mask fume hood);

3. Purification of exhaust gas;

4. Personal protection.

Productive poisons.

Productivetoxicant refers to substances used or exposed in production that can cause temporary or permanent pathological changes due to abnormal changes in the function or morphology of human organs and tissues.

1) Production raw materials, such as lead oxide used in the production of pigments, batteries, benzene used in the production of synthetic fibers, fuels, etc.;

2) intermediate products, such as nitrobenzene produced from benzene and nitric acid in the production of aniline;

3) Finished products, such as various pesticides produced by pesticide factories;

4) auxiliary materials such as rubber, benzene and gasoline used as solvents in the printing industry;

5) By-products and wastes, such as coal tar and asphalt produced during coking, sulfur dioxide produced during metal smelting;

6) Inclusions, such as kun mixed in sulfuric acid.

Legal analysis: The main measures are: 1. Substitution, that is, the use of non-toxic or low-toxicity chemicals to replace existing toxic and harmful chemicals; 2. Change the process, that is, eliminate or reduce the toxicity of chemicals by changing the process; 3. Isolation, that is, through measures such as closure and setting up barriers, to avoid direct exposure of workers to harmful environments; 4. Ventilation, that is, with the help of effective ventilation, the concentration of harmful gases, vapors or dust in the workplace is lower than the specified concentration, so as to ensure the health of the workers and prevent the occurrence of fires and accidents.

Legal basis: Regulations on the Safety Management of Hazardous Chemicals Article 20 Units that produce and store hazardous chemicals shall, according to the types and hazard characteristics of the hazardous chemicals they produce and store, set up corresponding safety facilities and equipment such as monitoring, monitoring, ventilation, sun protection, temperature regulation, fire prevention, fire extinguishing, explosion-proof, pressure relief, anti-poison, neutralization, moisture-proof, lightning protection, anti-static, anti-corrosion, anti-leakage, and protective embankment or isolation operation in the workplace, and in accordance with national standards, Industry standards or relevant national regulations shall carry out regular maintenance and maintenance of safety facilities and equipment to ensure the normal use of safety facilities and equipment. Units that produce and store hazardous chemicals shall set up conspicuous safety warning signs in their workplaces and safety facilities and equipment.

1. Airtight, ventilated and detoxification system;

2. Set up a local exhaust hood;

3. Purification of exhaust gas;

4. Personal protection.

5. Discharge out of the factory in time.

Industrial poisons, chemical substances that exist in small quantities in industrial production as raw materials, semi-finished products, finished products, by-products or wastes in industrial production, can have chemical or physicochemical interactions with the human body, destroy normal physiological functions, and cause dysfunction, disease, and even death.

1. Closed and rigid poison system: The system is composed of a closed cover, a ventilation pipe, a purification device and a ventilator. Its design principles and principles are basically the same as those of the dust-proof sealing, ventilation and dust removal system.

2. Local exhaust hood: in-situ sealing, on-site discharge, and on-site purification are an important technical criterion for ventilation and anti-virus engineering. The exhaust hood is a specific technical device to implement poison source control and prevent the spread of poisons. According to the structure, it is divided into two types: closed cover and open mask.

3. Purification of exhaust gas: harmless emission in industrial production is an important criterion that must be complied with in ventilation and anti-poison engineering. According to the characteristics of the conveying medium and the different production processes, the purification methods of harmful gases are also different, which are roughly divided into washing method, adsorption method, bag filtration method, electrostatic method, combustion method and high-altitude emission method.

4. Personal protection: The personal protection of workers who come into contact with poisons has special significance, and the portal for poisons to invade the human body can be invaded through the mouth and ** in addition to the respiratory tract. Therefore, all operations that come into contact with poisons should be provided with a targeted personal hygiene system, and if necessary, should be included in the operating procedures, such as no smoking, eating, bathing after shift, and no taking work clothes home.

Preventive measures are:

1. Closed ventilation and detoxification;

2. Local exhaust hood (closed hood with mask fume hood);

3. Purification of exhaust gas;

4. Personal protection.

Productive poisons.

Productivetoxicant refers to the use or contact in production of human organs and tissues that can cause abnormal changes in the function or morphology of human organs and tissues, resulting in temporary or permanent pathological changes.

The main sources of poison are as follows:

1) Production raw materials, such as lead oxide used in the production of pigments, batteries, benzene used in the production of synthetic fibers, fuels, etc.;

2) intermediate products, such as nitrobenzene produced from benzene and nitric acid in the production of aniline;

3) Finished products, such as various pesticides produced by pesticide factories;

4) auxiliary aging materials, such as rubber, benzene and gasoline used as solvents in the printing industry;

5) By-products and wastes, such as coal tar and asphalt produced during coking, sulfur dioxide produced during metal smelting;

6) Inclusions, such as kun mixed in sulfuric acid.
