Here are a couple of examples. Exhibit A definitely has something in it, but there is no label to tell us what this is.Is it product (chemical labeling violation)? Is it waste? If so, is the container closed? If a waste, there are multiple problems with this container, including labeling.
Exhibit B is also something that would be cited. The reason is that it is labeled as “used chemical.” We have no idea if it is used acetonitrile or if the acetonitrile bottle was used to collect something else. By contrast, sometimes laboratory workers will simply pen in the word “Used” immediately above the name of the chemical on the manufacturer’s label. This would be acceptable and not a violation of this checklist item because it is obvious that the lab worker intended to convey that the bottle contains used acetonitrile.
The container in Exhibit C is labeled “Used Solvents” and identifies the constituents.
The container in Exhibit D includes the percentages of the mixture.
Would you cite the lab for the Exhibit C container for not having the percentages?
In this case, you would not because you have all the information needed to make a waste determination. The percentages of the mixture may not be known until the container is full and would be provided with HMCT.
