Why is silica gel dangerous

Is silica gel dangerous ?

http://www.ashirwadchemicals.net/faq-s.htm

Non-indicating (white) silica gel is non-toxic and non-flammable, it is very inert with a very high melting point. It is very much like sand and thus can safely be sent by any means of transport.

Why Is Silica gel So Dangerous?

Q: Ok I am super-curious so I decided to open a silica gel pack and dump it in the sink. I slashed water on it and they started crackling. are they okay to touch? what happens if you eat some?

A: INDRODUCTIONSilica gel is a granular, porous form of silica made synthetically from sodium silicate. Despite the name, silica gel is a solid.Silica gel is most commonly encountered in everyday life as beads packed in a semi-permeable plastic. In this form, it is used as a desiccant to control local humidity in order to avoid spoilage of some goods. Because of poisonous dopants (see below) and their very high absorption of moisture, silica gel packets usually bear warnings for the user not to eat the contents. If consumed, the pure silica gel is unlikely to cause acute or chronic illness, but would be problematic nonetheless. However, some packaged desiccants may include fungicide and/or pesticide poisons. It is not known whether these would be labelled specifically. Food-grade desiccant should not include any poisons which would cause long-term harm to humans if consumed in the quantities normally included with the items of food.PROPERTIESSilica gel’s high surface area (around 800 m²/g) allows it to absorb water readily, making it useful as a desiccant (drying agent). Once saturated with water, the gel can be regenerated by heating to 120 °C (250 °F) for two hours. Some types of silica gel will “pop” when exposed to enough waterHAZARDSAlone, silica gel is non-toxic, non-flammable and chemically unreactive. However, some of the beads may be doped with a moisture indicator, such as cobalt(II) chloride, which is toxic and may be carcinogenic. Cobalt (II) chloride is deep blue when dry (anhydrous) and pink when moist (hydrated).Crystalline silica dust can cause silicosis but synthetic amorphous silica gel is non-friable, and so does not cause silicosis. A chemically similar substance with far greater porosity is aerogel.

Why do they use Silica gel in shoes , chairs etc a lot of new products?

Q: u know those little bags of silica get and they say “do not eat” mixed within the product. what is its use?is it dangerous?

A: Silica jel is a white powder that is very moisture absorbant. It is used in a variety of product containers,especially electronics, to protect against moisture contamination. While it is not dangerous itself (although it can be used as a pesticide-bugs eat it, it sucks the moisture out of their system-they die!), it is sometimes coated with moisture indicators which can be poisonous. That is why the packets have the warning-you don’t know which ones have the indicator.
