1. Important measures for the prevention and control of waste gas hazards in injection molding processing
1. Strictly control the injection molding process. Using appropriate injection molding conditions according to the properties of raw materials to reduce unnecessary gas release is not only beneficial to injection molding production, but also helpful to reduce gas hazards.
2. The injection molding workshop is separated independently. Separate the injection molding process from other processes to avoid unnecessary gas pollution.
3. Install waste gas treatment system. Ensure the ventilation of the injection molding workshop, install an exhaust gas discharge system, and conduct a harmless treatment of the exhaust gas in a centralized diversion and exhaust gas treatment pool to reduce the chance of injection molding personnel being exposed to the exhaust gas.
4. Regular physical examination. Personnel employed in injection molding processing should undergo regular physical examinations to clarify whether various indicators are in a safe state. If there are obvious respiratory system, cardiovascular system problems, or liver, kidney and other patient conditions, they should not engage in injection molding work and should be timely Changing of the guard and related treatment.
2. General manifestations of waste gas poisoning from injection molding processing
Injection molding process exhaust gas poisoning is divided into two types: acute poisoning and chronic poisoning:
Acute poisoning: Absorb a large amount of toxic gas in a short time, such as acrylonitrile monomer, accompanied by upper respiratory tract and eye irritation. In severe cases, there may be paroxysmal convulsions of limbs and coma.
Chronic poisoning: Chronic poisoning usually has no obvious symptoms, but long-term exposure to harmful gases will cause dizziness, fatigue, anxiety, and many kinds of debilitating symptoms such as dreams and unstable sleep.
