Quartz sand is a very common raw material in industrial production, from glass melting, casting sand, ceramic glaze, to stone cutting and concrete drilling in building decoration, to sandblasting and rust removal, artificial quartz stone countertop processing, and oil and gas field fracturing proppants. Its presence is almost everywhere. These seemingly harmless milky white or semi transparent particles will continuously generate a large amount of fine dust during transportation, crushing, screening, mixing, polishing, and other processes.
Once the crystalline silica contained in it is inhaled deep into the alveoli, it may cause irreversible silicosis. In recent years, some artificial stone processing industries have even seen cases of young workers developing rapidly progressing silicosis, sounding a heavy alarm.
Personal protection, guarding the last checkpoint of breathing. When entering the dust work area, it is necessary to wear a particle respirator correctly according to the on-site concentration. In routine homework, protective equipment that fits the face with such masks can provide effective filtration, and should reach at least KN95 level; When the dust concentration is high or the continuous operation time is long, it is necessary to upgrade to protective equipment with stronger sealing such as Fangdun half face mask, and form a reliable barrier with high-efficiency filter cotton.
Before wearing, carefully check the tightness to ensure that the nose clip is properly shaped and there is no air leakage at the edges during breathing. The filter cotton should be replaced in a timely manner according to the instructions, and should not be repeatedly used after washing with water or blowing air. It is best to remove and wear masks in a dust-free environment to prevent hand contamination. Work clothes, safety helmets, etc. should also be regularly replaced and cleaned, and clothing contaminated with dust should not be taken home.
Every dust prevention measure is a dam built for breathing. When the filter cotton blocks the invisible sharpness, when the tightly fitted Fangdun half mask isolates dust from the mouth and nose, this is not just a standardized operation, but also a message to my future self: I want to return to my family completely and healthily. Individual protection is the bottom line that cannot be lost. Preventing one inhalation is the key to maintaining confidence for a lifetime.
