Practice notes
It is important to reinforce the supply of water amps with the clear message that the reason it's being given out is to reduce the sharing of water, which is a major cause of hepatitis C transmission. The amps are for personal use and any remaining water should be thrown away.

The blue dot!
It is also important for all clients to be shown how to use the amp snapper, preferably with a practical demonstration in the needle exchange, using an ampoule.

Disposal
Clients should be advised to throw away used ampoules with other used injecting equipment in a sharps bin. However, where no sharps bin is available,ampoules can be ground to a fine powder under the heel, rendering them harmless or disposed of in domestic waste or recycling scheme.
