The Office for Product Safety Standards have issued an alert regarding the use of chainsaw disc attachments used on angle grinders. They state that these attachments are unsafe and should not be used and that anyone in possession of one should return it to where they purchased it for a refund.
See the poster for further information.
The OPSS have also produced a risk summary document explaining the hazards which may be of interest.
