The main component of silica gel is silica, which has stable chemical properties and does not burn. Silica gel is a kind of amorphous silica. The dust content in the workshop should be controlled not more than 10 mg/cubic meter. The ventilation should be strengthened and masks should be worn during operation.
Silica gel has a strong adsorptive capacity, which can dry human skin. Therefore, work clothes should be well worn during operation. If silica gel enters the eye, it needs to be washed with a lot of water and treated by a doctor as soon as possible.
Blue silica gel has potential toxicity due to its small amount of cobalt chloride. It should be avoided from food contact and inhalation. If poisoning occurs, doctors should be immediately consulted for treatment.
Silica gel can be reused after regeneration because it adsorbs water vapor or other organic substances in the medium during its use.
