Conduct routine self-audits for all laboratories to minimize reagent accumulation and maximize recycling and sharing of surplus materials. Chemical Purchasing Policies Tighten puchasing controls. Institute procedures that are designed to restrict hazardous chemical purchases to those needed for the current instructional or research programs and in minimal amounts that reflect short term use. A centralized purchasing program can monitor requests for chemicals, implement policies such as staggered deliveries, sharing of chemicals among common users, and plans for leftover chemicals. Consider disposal cost at time of purchase.
Many chemicals deteriorate with time.
When they must be removed, the disposal cost may be 20 to 50 times the original purchase price. The real cost of chemicals should be regarded as the initial purchase price plus any ultimate disposal costs. Disposal costs can often offset savings from buying in quantity. Consider handling and disposal requirements. If the facility does not have adequate storage and safety provisions for a chemical, its purchase should be discouraged.
