Using water unnecessarily in laboratories is not only a waste, it reflects poorly on staff and is a bad example for others. Use of water in water aspirators and for cooling (water used once and run to waste) should be discontinued.
Policies and practices for immediate clean up of water spills should be implemented.

l9NH+A[o&Zt
Trade waste regulations require all discharges to trade waste to be between pH 6 – 10. Concentrated acid, diluted one million to one with water, may still be below pH 6. Acid waste can cause long-term damage to sewers and can generate gases harmful to maintenance workers in the sewers. All waste acid and alkali should be collected and neutralised (and can be tipped down the sink only if there are no hazardous substances present).
