Sorry, posting for traffic.
Just bought a sandpit and was about to order some nice cheap playsand from Tesco when I found out about crystalline silica and asbestos tremolite. Both known carcinogens. Common to find them in play sand apparently if the sand is manufactured from crushed rock instead of being natural sand taken from a beach or river.
Am looking at playsand that claims to be non toxic and conforms to BS EN71-3-2013, e.g. ELC and others, but the standard does not cover silica or asbestos tremolite, and none of them say how the sand is produced / sourced.
Has anyone already done the homework on this and know of a properly safe playsand?
I am rather shocked to see that Tesco's playsand is silica sand now.
