This is to establish the Forum's attitude to recommendations to use kiln-dried sand and other building sands for blasting. Please don't suggest their use. Using silica based sands is illegal per-se in a business environment (apart from a couple of specialised applications) and you could be prosecuted under Health and Safety at Work regulations for doing so. It was made illegal because it's dangerous, which means it's still dangerous in a DIY environment and a Council could prosecute an individual under environmental protection legislation. The danger comes from silicosis, a lung disease caused by inhaling silica based dust. It's incurable and can be fatal. Plenty of info if you Google it. That established, we can obviously not condone its use. If we did and a member got into trouble we could find ourselves embroiled in litigation. Having proper PPE, filters, extractors &c&c is no defence, it's using the stuff that's the problem. Any posts containing suggestions to use silica sands (or other non-approved media) will be edited or deleted. Sorry to be a Jobsworth, but we've got to stay on the right side of the law. Have a look in the links section under "Grit Blasting" for details of suitable media. Thanks!
