c. Accumulation times shall be kept to the minimum practical length of time for the following
reasons:
(1) Some chemicals become unstable or degrade over time or if exposed to heat or light;
(2) Sometimes personnel changes occur and the new person can't be sure what is in a
container even if it is labeled, and
(3) Procedures may change and reagents or product formulations used may also change over
time.
14.7 Inspecting Waste Accumulation Areas
The EO will inspect SAAs periodically and will identify deficiencies and document them within
the Environmental Management System’s Problem Reporting System Database for action.
14.8 Special Requirements for Laboratories Adding Wastes to Accumulation
Containers
14.8.1 The following requirements apply to laboratories:
a. Do not store wastes in glass containers unless it is the only compatible material;
b. Do not store wastes in laboratory vent hoods unless there is no safe alternative- hoods can
be used for the transfer of wastes or chemicals to containers and for temporary observations of
waste transfers to confirm that no vapors or heat are generated and the waste can be safely
sealed for storage;
c. When adding wastes to accumulation containers, move the container to the hood to add
wastes;
d. Do not immediately close the container after adding wastes - allow a few minutes to ensure
that there will be no reaction that causes fumes or gas to be generated;
e. Once you are sure that no gases will be generated, close the container tightly and move it to
its proper storage location;
f. Maintain a detailed log of all waste added to an accumulation container;
g. Mix only the minimum amount of chemicals needed to do the job in order to minimize the
amount of accumulated waste that will need disposal;
h. Do not store/accumulate wastes for more than three months;
i. Do not mix waste that contains any concentration of nitric acid with any other wastes. Nitric
acid is extremely reactive, is both an oxidizer and a corrosive, and will generate heat and
gases when mixed with organics and other similar materials; and
j. All laboratories are required to develop and maintain a chemical hygiene plan. A qualified
(degreed) chemist must conduct a review whenever new or revised laboratory procedures or
