Hidden Dangers of Ordinary
Sand Box Play Sand

Play Sand is part of being a child, our best times are spent playing in Sandbox Sand. Colored Safe Sand is so much a part of childhood, from Arts and Crafts Sand, Sandbox Sand, Aquarium Sand for our fish to Play Sand. Check below for some of the warnings for non-safe Play Sand.

The warning displayed below is directly from a bag of sand box play sand purchased from a local large scale retail chain:


This product contains crystaline Silica (CAS 14808-60-7), a common mineral found in sand and stones Excessive inhalatiion of respirable silica dust may cause cancer and lung disease. Avoid breathing dust generated from use of this product. Where an approved respirator in dusty areas. First aid: Move to fresh air. See MSDS* for additional information.

* Material Safety Data Sheet

Other products carry similar warnings. The next paragraph is reprinted from a can of basement water leak repair cement:

Cancer Hazard. contains Crystalline Silica which can cause cancer. Do not breath dust. wear dust mask or respirator when handling this product.

Below is an Excerpt from Wikipedia's Online Encyclopedia

When small silica dust particles are inhaled, they can embed themselves deeply into the tiny alveolar sacs and ducts in the lungs, where oxygen and carbon dioxide gases are exchanged. There, the lungs cannot clear out the dust by mucous or coughing.

When fine particles of silica dust are deposited in the lungs, macrophages that ingest the dust particles will set off an inflammation response by releasing tumor necrosis factors, interleukin-1, leukotriene B4 and other cytokines. In turn, these stimulate fibroblasts to proliferate and produce collagen around the silica particle, thus resulting in fibrosis and the formation of the nodular lesions. The inflammatory effects of crystalline silica are apparently mediated by the Nalp3 inflammasome.

Furthermore, the surface of silicon dust can generate silicon-based radicals that lead to the production of hydroxyl and oxygen radicals, as well as hydrogen peroxide, which can inflict damage to the surrounding cells.

Characteristic lung tissue pathology in nodular silicosis consists of fibrotic nodules with concentric "onion-skinned" arrangement of collagen fibers, central hyalinization, and a cellular peripheral zone, with lightly birefringent particles seen under polarized light. In acute silicosis, microscopic pathology shows a periodic acid-Schiff positive alveolar exudate (alveolar lipoproteinosis) and a cellular infiltrate of the alveolar walls.
