Remove toxins
Eliminating toxic substances from the production process and replacing toxic and highly toxic materials or processes with non-toxic or low-toxic materials or processes are the fundamental methods to solve the anti-virus problem and the important research direction of anti-virus. Such as water-soluble coatings without organic solvents, cyanide-free cyanide-free electroplating, etc.
Control poison concentration
Reducing the content of toxic substances in the air to reach or lower than the maximum allowable concentration is the central link to prevent occupational poisoning. Mechanized, sealed, continuous and automated production can be realized through technological innovation, and factories and equipment can be rationally arranged. If the open equipment is changed into closed equipment, the feeding, mixing, handling and packaging of toxic materials will be mechanized, sealed and automated. Isolation operation and instrument control can play an isolation role to prevent people from contacting harmful substances and causing poisoning. When toxic gases still escape from the closed production equipment, or when the equipment cannot be completely closed due to production conditions, ventilation and detoxification measures can be taken to prevent viruses. There are three methods of ventilation and detoxification: local ventilation, local air supply and comprehensive ventilation, among which local ventilation has the best effect and is the most commonly used. Ventilation and detoxification can timely discharge or dilute the toxic gases in the workplace to below the maximum allowable concentration stipulated by the national health standards. Purification and recovery of toxic gases discharged in the production process can not only effectively control the harm of toxic substances to people or the environment, but also play a role in turning waste into treasure, which is of great significance to production and antivirus. Strictly implement the production process and safety operation rules, strengthen the inspection and maintenance of production equipment, and prevent running, running, dripping, leaking and polluting the environment. Strengthen air monitoring in production workshops, and control the concentration of toxic substances in the air so that it does not exceed the maximum allowable concentration stipulated by the national industrial hygiene standards.
Personal protection and health care
Personal protection and personal hygiene are of great significance to prevent occupational poisoning. In production operations, appropriate protective clothing and articles must be provided. For example, workers exposed to strong acid and alkali should be equipped with acid-resistant and alkali-resistant work clothes, and those exposed to toxic dust should be equipped with dust-proof work clothes. According to the toxic and harmful degree of the workplace, provide corresponding respiratory protection articles, such as dust-proof gas masks, gas masks, air respirator, oxygen breathing apparatus, etc. In order to maintain good personal hygiene conditions and reduce the chance of toxic behavior, the workshop should be equipped with hand washing, shower facilities and personal lockers. And contact with toxic substances that are absorbed by the skin and have high risk of local action, and there should be equipment for skin cleaning, disinfection and eye washing. Operators are not allowed to heat or bake food on the production stove in the toxic workshop, and it is forbidden to eat in the workshop. They should wash their hands before meals, and don't take food with contaminated hands. Strictly carry out pre-job physical examination and regular physical examination, so as to find problems early and take measures in time. Carry out occupational health education, so that employees can understand the nature and harm of toxic and harmful substances, master the basic knowledge of preventing occupational poisoning, and enhance their self-protection awareness and ability.
Health supervision and monitoring management
In order to effectively prevent and control occupational poisoning, preventive health supervision, regular health supervision and regular inspection system must be strictly implemented. Preventive health supervision is to strictly implement the "three simultaneities" review and supervision of occupational health, so as to ensure that occupational health protection facilities and the main project of the project are designed, constructed, accepted and put into production at the same time. Regular health supervision means that enterprises and individuals strictly implement national and local health laws and regulations in their daily production activities, so as to control the concentration of toxic substances in workplaces below the national health standards and prevent occupational poisoning. The regular monitoring system is to determine the measuring points, hang signs and implement fixed-point regular monitoring management for the operating points that are frequently operated or regularly observed in the production process and are easy to contact with harmful factors.
