Relevant technical measures such as materials and processes, production equipment (devices), controls and operating systems, leakage of toxic media (including accidental leakage), and emergency measures shall be optimized and combined, and comprehensive countermeasures shall be taken.
(1) Materials and Processes

Replacing toxic and highly toxic processes and materials with non-toxic, low-toxic processes and materials is a fundamental measure for anti-virus.

(2) Process Equipment (Apparatus)

Production facilities should be closed and pipelined to achieve negative pressure production as much as possible to prevent leakage of toxic substances and escape.

The mechanization, proceduralization and automatic control of the production process can make the operator not touch or less contact with toxic substances and prevent accidental poisoning.

(3) Ventilation purification

If technical and economic conditions limit the use of toxic substances and the natural ventilation does not meet the requirements, the necessary mechanical ventilation detoxification and purification (discharge) devices shall be installed so that the concentration of toxic substances in the air of the workplace is limited to the maximum allowable concentration. Value below.

The mechanical ventilation detoxification method mainly includes three types: full ventilation, partial exhaust, and partial delivery.

1 full mechanical ventilation

The entire plant is ventilated and ventilated.

2 Partial mechanical ventilation

Ventilation and ventilation of certain parts of the factory premises have improved the local operating environment. Local mechanical ventilation includes local air supply and local air exhaust.

(4) Reliable accident treatment devices and emergency protection facilities must be provided for equipment and workplaces that may cause major accidents due to leakage of toxic substances.

A poisonous accidental safety discharge device (including storage tanks), an automatic detection and alarm device, and a chain accident detoxification device shall be installed, and a device for detoxification (including flushing, dilution, and reduction of toxicity) shall be provided at the time of accident leakage.

(5) According to the nature of toxic substances, the characteristics of toxic operations and protection requirements, accident cabinets, first aid kits and personal protective equipment (antivirus clothing, gloves, shoes, glasses, filter-type gas masks, long Masks, air respirators, oxygen masks, etc.) The service radius of sanitary protection facilities such as human irrigators and eyewashers should be less than 15m.

(6) Other measures

Segregation is achieved on the basis of airtight and ventilating production equipment (isolation of the operation site from highly toxic substance production equipment that may cause major accidents) and remote control operation.

With detoxification purge and flushing facilities during inspections.

The ceilings, walls, and floors of factories and warehouses that manufacture, purchase, store, and handle extremely hazardous and highly hazardous poisons shall be smooth and easy to clean. Special protective layers such as waterproof and anti-corrosion and special negative pressure cleaning devices and cleanings shall be added when necessary. facility.

(7) Adopt management measures such as anti-drug education, regular inspections, regular medical examinations, regular inspections, guardianship operations, acute poisoning and hypoxia asphyxiation rescue training.
