so far, almost none of the printers do not use more or less gasoline and kerosene is used as ink cleaner, although the printing is very clear danger of gasoline: the first is safety. Petrol flash point (that is, encountered fire explosion of steam temperature) of more than 20 degrees, if ventilation is not good in a printing plant, are prone to dangerous situations. Even if air circulation inside the plant well, danger does not occur in the workshop, but cleaned ink gasoline and kerosene will be workers poured down the drain, on soil and water quality in the needless to say, while gasoline floating on the water, outdoor temperature high season, there is also a risk of explosion.
