Bests & Worsts Reviews from Amazon

I though I bough safe sand until I felt nose and lung irritation after playing with my son. I did a little more reading and the sand has silica. I use silica at work and I know we need breathing protection to prevent silicosis, a well know carcinogen in my industry. According to the SDS (safety datasheet) of the product in the manufacturer website it has a category 3 hazard for single exposure and category 1 for repeat exposure. After experimenting with the proper breathing protecting the sand has lots of dust and it will be hard for my kid to play with it without inhaling the dust, with silica. This should be part of the labeling and on the amazon product information. Specially since I felt the irritation right away.
