NR 662.206(1)(a)2.b.b. The type or class of chemical, such as organic solvents or halogenated organic solvents.

NR 662.206(1)(b)(b) The following information may be affixed or attached to the container, but shall at a minimum be associated with the container:

NR 662.206(1)(b)1.1. The date that the unwanted material first began accumulating in the container.

NR 662.206(1)(b)2.2. 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:

NR 662.206(1)(b)2.a.a. The name and description of the chemical contents or composition of the unwanted material, or, if known, the product of the chemical reaction.

NR 662.206(1)(b)2.c.c. A description of the manner in which the chemical was produced or processed, if applicable.

NR 662.206(2)(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:

NR 662.206(2)(a)(a) Containers are maintained and kept in good condition and damaged containers are replaced, overpacked, or repaired.

NR 662.206(2)(b)(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.

NR 662.206(2)(c)(c) Containers shall be kept closed at all times, except for any of the following:

NR 662.206(2)(c)2.2. 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.

NR 662.206(2)(c)3.3. When venting of a container is necessary under any of the following conditions:

NR 662.206(2)(c)3.a.a. For the proper operation of laboratory equipment, such as with in-line collection of unwanted materials from high performance liquid chromatographs.

NR 662.206(2)(c)3.b.b. To prevent dangerous situations, such as build-up of extreme pressure.

NR 662.207NR 662.207 Training. An eligible academic entity shall provide training to all individuals working in a laboratory at the eligible academic entity and maintain documentation, as follows:

NR 662.207(1)(1) Training for laboratory workers and students shall be commensurate with their duties so they understand the requirements in this subchapter and can implement them.

NR 662.207(2)(2) The required training under this subsection may include any of the following:

NR 662.207(2)(a)(a) Instruction by the professor or laboratory manager before or during an experiment.

NR 662.207(3)(3) An eligible academic entity that is a large quantity generator shall maintain documentation for the durations specified in s. NR 665.0016 (5) demonstrating training for all laboratory workers that is sufficient to determine whether laboratory workers have been trained. Examples of documentation demonstrating training include:
