Secondary Containment Requirements

The requirement for secondary containment of waste containers in an SAA
or MWSAA is a best management practice throughout industry and
government. Secondary containment capacity of 110% of the largest
container being stored is an industry standard. The secondary
containment requirement does not depend on the actual volume of waste
being stored, only the largest container in storage. Remember that
physical space and segregation of incompatible chemicals in secondary
containment are important as well. Each container should be stored
safely.

Metal containment is acceptable for [non]{.underline}-corrosive wastes.

For example:

A lab SAA contains 3-one liter bottles of waste. Secondary containment
should be able to contain 110% of 1 liter or 1.1 L. In this case an
8"x10" plastic photo tray is acceptable. (8"x10"x1" = 80 cubic inches or
1.3 liters). See ordering information below.

For example:

A lab SAA contains a 5-gal flammable waste can, 2-1 pint bottles, and a
20 ml vial. Secondary containment should be able to contain 110% of 5
gallons or 5.5 gallons (20.8 L). In this case a Polyethylene, Rubbermaid
5-gal, 18"x26"x3.5" is appropriate (18"x26"x3.5" = 1,638 cubic inches or
27.3 L). See ordering information below.

For example:

A lab MWSAA has a collection container for scintillation vials. The
typical storage configuration is a plastic bag inside a 12.2 gal
container. A full bag is approximately 750 vials (20 ml each) or 15
liters of liquid. Secondary containment should be able to contain 110%
of 15 liters or \~4.4 gallons. The secondary containment requirement is
satisfied by the plastic bag inside a 12.2-gallon container. The plastic
bag and 12.2 gallon container is provided by Waste Management.

## Secondary Containment Options

Secondary containment tubs and trays are available from several
suppliers with whom LBNL has system contracts that facilitate ordering.
Other plastic trays and tubs are available from suppliers such as VWR
with a two-day delivery time. The following tables list various
secondary containment options based on typical containers found in many
Berkeley Lab research labs. These are only examples. Other suppliers may
have equally acceptable items for secondary containment. If you have
questions, please contact your Generator Assistant.

Container size: One liter or less
