Universal Citation: WI Admin Code ยง NR 662.206
Current through August 26, 2024
An eligible academic entity shall manage containers of unwanted material while in the laboratory in accordance with all of the following requirements:
(1) LABELING. An eligible academic entity shall label unwanted material as follows:
(a) All of the following information shall be
affixed or attached to the container:
1. The
words "unwanted material" or another equally effective term that is to be used
consistently by the eligible academic entity and that is identified in part I
of the laboratory management plan.
2. Sufficient information to alert emergency
responders to the contents of the container. Examples of information that would
be sufficient to alert emergency responders to the contents of the container
include:
a. The name of the
chemical.
b. The type or class of
chemical, such as organic solvents or halogenated organic solvents.
(b) The
following information may be affixed or attached to the container, but shall at
a minimum be associated with the container:
1. The date that the unwanted material first
began accumulating in the container.
2. Information sufficient to allow a trained
professional to properly identify whether an unwanted material is a solid or
hazardous waste and to assign the proper hazardous waste code, under s.
NR 662.011. Examples of information that would allow a
trained professional to properly identify whether an unwanted material is a
solid or hazardous waste include:
a. The name
and description of the chemical contents or composition of the unwanted
material, or, if known, the product of the chemical reaction.
b. Whether the unwanted material has been
used or is unused.
c. A description
of the manner in which the chemical was produced or processed, if
applicable.
(2) MANAGEMENT OF CONTAINERS IN THE LABORATORY. An eligible academic entity shall properly manage containers of unwanted material in the laboratory to assure safe storage of the unwanted material, to prevent leaks, spills, emissions to the air, adverse chemical reactions, and dangerous situations that may result in harm to human health or the environment. Proper container management shall include all of the following:
(a) Containers are maintained and
kept in good condition and damaged containers are replaced, overpacked, or
repaired.
(b) Containers are
compatible with their contents to avoid reactions between the contents and the
container; and are made of, or lined with, material that is compatible with the
unwanted material so that the container's integrity is not impaired.
(c) Containers shall be kept closed at all
times, except for any of the following:
1.
When adding, removing or bulking unwanted material.
2. A working container may be open until the
end of the procedure or work shift, or until it is full, whichever comes first,
at which time the working container shall either be closed or the contents
emptied into a separate container that is then closed.
3. When venting of a container is necessary
under any of the following conditions:
a. For
the proper operation of laboratory equipment, such as with in-line collection
of unwanted materials from high performance liquid chromatographs.
b. To prevent dangerous situations, such as
build-up of extreme pressure.
