Printing plants use a variety of chemicals, including inks, solvents, etc. These substances release a variety of toxic and harmful gases during the volatilization process, which has long been a major health hazard in industrial production. These gases mainly include:
1. VOC gases such as benzene and toluene. Long-term inhalation of these substances may cause dizziness, nausea, respiratory irritation and other symptoms, and in severe cases may damage the liver and nervous system.
2. Ozone: Ozone is generated during printing operations. Long-term exposure may cause damage to the lungs and respiratory tract.
3. Ammonia: Ammonia in solvents and inks evaporates to produce ammonia. Long-term exposure may cause inflammation.
4 Carbon monoxide: Carbon monoxide produced by incomplete combustion of fuel may cause symptoms such as headaches and nausea.
5. Sulfur dioxide: Sulfur dioxide formed by oxidation of sulfur components in fuel during combustion may cause respiratory problems and lung damage.
6. Nitrogen oxides: Nitrogen oxides generated during high-temperature combustion may cause damage to the respiratory tract and lungs.
7. Chlorine: The residual chlorine components in printing inks and glues may volatilize during the heat process, which is harmful to the respiratory tract and lungs.
8. Zinc oxide fume: High-temperature curing during screen printing may produce zinc oxide fume, which may cause damage to the lungs if inhaled for a long time.
Preventive measures:
1. Environmentally friendly materials: Choose environmentally friendly materials such as harmless soy ink to reduce the generation of toxic and harmful gases.
2. Strengthen ventilation: Install an effective ventilation system to ensure air circulation in the workplace and discharge harmful gases in time. The concentration of toxic gases can be reduced by mechanical ventilation and natural ventilation.
3. Equipped with detection and alarm system: Install a toxic and harmful gas detection and alarm system to monitor the concentration of toxic gases in real time. When the concentration exceeds the standard, it will automatically alarm and link the exhaust system.
4. Equipped with protective equipment: Configure corresponding protective equipment according to the nature of the toxic gas, such as positive pressure respirators, filter-type gas masks, etc.
5. Regular testing: Regularly test the concentration of toxic gases in the working environment to ensure compliance with safety standards.
6. Strengthen training: Train employees on the recognition of toxic gas hazards, the use of protective equipment, and emergency rescue drills.
7. Regularly check the sealing of equipment: Check the sealing of pipelines every month and calibrate the accuracy of gas detection instruments every quarter.
8. Formulate emergency plans: Clarify the leakage disposal process, set up emergency evacuation channels and assembly points, and conduct regular drills to enhance emergency disposal capabilities.
9. Adopt new technologies to transform production processes: Actively adopt new technologies to transform production processes and reduce the generation of toxic and harmful gases.
The online gas alarm controller produced by our company can detect volatile organic compounds (VOCs), combustible gases (such as isopropyl alcohol, ethanol, ethyl acetate) and harmful gases such as ozone, carbon monoxide, ammonia, chlorine, etc. generated during printing operations. Portable detection equipment, fixed detection equipment and online monitoring systems can be purchased according to needs.
