Why Does Play Sand Have a Cancer Warning?

With arsenic in brown rice and radioactive tissue box holders¬†already making headlines, you now get to worry about… wait for it…


John and Sherry over at the fabulous Young House Love recently built a lovely sandbox for their little girl and filled it with sand, only to discover an ominous warning on the sand bags¬†about the silica in the sand potentially causing cancer. Yes, common play sand carries one of those those “Warning in the State of California” labels (like the ones on your Christmas lights). This is because California is either a) is full of crazy hippies or b) actually protects its consumers… I can’t decide.

Isn’t silica, like, in beach sand? Well, yes, but… apparently all that dust in the newer, manufactured play sand may be unhealthy. At least that’s the best I could glean from YHL, OSHA, the (albeit biased) Safe Sand website, and a bunch of crazy moms (like me) online. I really wanted to find an official EPA statement about this specific issue, but it didn’t happen… The OSHA information is not specifically about play sand and the EPA link on the Safe Sand website is dead.

I felt for John and Sherry, I really did, because this is totally the sort of thing that would happen to me. I’d be standing there, 200 lbs of sand unloaded before me, staring at a warning label, wondering just how dangerous this stuff is for my kid. I would think “aw, screw it, it’s fine” and then I’d panic, change my mind, and be hauling sand like a crazy person out of my kid’s sandbox. (They replaced their sand with pea gravel).

I saw cheap “natural” play sand at Home Depot, and that looks like a good option, but that, too, had the warning. I would assume that’s safer, though? …Now that it’s time to refill our sandbox, I’ll either buy that or spend an arm and a leg buying Safe Sand from California. Tempest in a teapot? Probably. But it’s hard to let your kid play in something that says “cancer” right on the bag.
