During the high-temperature melting and high-pressure injection molding process of plastic particles in the injection molding workshop, volatile organic compounds and additives will be generated, which will decompose into steam when heated. To ensure occupational health, injection molding workers need to correctly choose and wear gas masks to effectively reduce the risk of inhaling harmful gases.
The main pollutants in the injection molding environment include organic gases such as styrene and formaldehyde, as well as volatile organic solvents used during mold cleaning. If the ventilation in the workshop is insufficient, long-term inhalation may cause respiratory discomfort. Therefore, the scientific selection of respiratory protective equipment is crucial. For organic vapors, a self-priming filter type gas mask that meets the GB2890-2009 standard should be selected and equipped with a filter box; If dust is present in the environment, a comprehensive filter can be used.
When the concentration of toxic substances exceeds the standard by ≤ 10 times, a self-priming filter half mask is applicable; When exceeding the standard by ≤ 100 times, a full face cover should be used; If the concentration is greater than 100 times or there is a risk of hypoxia, an isolated respirator should be used. When making a purchase, it is necessary to confirm that the product has LA labor safety certification, and the mask body is preferably made of food grade liquid silicone or high-purity natural rubber material.
During use, it is necessary to closely monitor the status of the filter cartridge. If you smell an odor, have significantly increased respiratory resistance, or experience discomfort such as dizziness or nausea, you should immediately evacuate to a safe area and replace the filter components. It is recommended to use the filter box for no more than 8 hours per day after opening, and it should be stored in a dry, ventilated, and cool place after use. Standardized respiratory protection is not only a requirement for safety production, but also a practical guarantee for personal health.
From scientific selection to standardized wearing, to timely replacement and proper storage, every step is related to the ultimate effectiveness of protection. I hope that all injection molding workers can implement the above points into their daily operations, ensuring that they are checked before wearing, tested when wearing, and replaced when using. Take every correct wearing and inspection as a solemn commitment to life. Only by strengthening this respiratory defense line can we truly achieve a win-win situation between safe production and healthy living.
