1. Purpose

This describes the protocol for use of the Kill Bin, which is a beach-filled container, located under or near the sink, used for the inactivation and disposal of biological waste and disposable lab plastics which may have become biologically contaminated.

2. Scope

This document should be consulted prior to use of the Kill Bin for waste disposal.

3. Responsibilities

The operator of the Kill Bin is responsible for his or her own safety, and the safety of others, while disposing of waste. The major danger to health is the large quantity of bleach contained in the bin. Spilled bleach can cause severe damage to eyes and skin, and it is harmful if swallowed of if its vapours are inhaled. For these reasons, and because the surfaces of the bin may have been contaminated by waste from a previous disposal, the bin should used with gloved hands, and opened carefully.

4. Materials

The bin requires a 60/40 bleach/water mix. See section 7.3, "Refilling the Kill Bin", for more details.
