Examples of Chemical Classifications for

Proper Chemical Disposal

In the process of providing assistance to schools under the New

Hampshire Pollution Prevention in Schools Project, NHPPP has

classified over 250 science laboratory chemicals for proper disposal.

The list of examples below is provided for schools to recognize that

chemical classification is one of the first steps taken in the disposal

process. Changes in government regulations can effect a change in a

chemical’s classification, which will subsequently effect the list below.

Should your school be in need of disposing of laboratory chemicals,

NHPPP is available to assist you.

NHPPP used a variety of technical resources to develop the chemical

classifications listed below. Such resources included a review of the

chemical classification under RCRA (Resource Conservation and

Recovery Act) and DOT (Department of Transportation), the pH of

the compound, and the chemical’s properties of reactivity,

flammability, and toxicity. A chemical’s incompatibilities were also

noted.
