Samples.doc samples list. Containers of materials you are leaving. your name ____________________ Date _________ Page _____ of _____ revised February 2015 https://www.chem.purdue.edu/chemsafety/Files/samples.docx Any and all containers of chemicals and mixtures (including peptides, aqueous solutions, buffers, washes, tissue cultures, and/or synthetic samples) that you are leaving at Purdue -- NOT INCLUDING THOSE IN MANUFACTURERS’ CONTAINERS – in a cabinet or hood or drawer or refrigerator or freezer…. -- must be accounted for here. Including anything taken possession of by your professor or another group member. Repeat: this applies only to materials which are not in original manufacturers' containers. The manufacturers’ containers generally have completely adequate labeling and usually do not become unknowns, so they are not of concern here. You are to leave behind only what your supervisor has signed (initialed) for in the list. If any material’s identity is sensitive (confidential/proprietary) it will be acceptable to omit chemical identification from the list and use a code that is associated with the container label. Hazard characteristics must be identified on this list for all items. The safety officer is likely to ask to see inspect container labels containers during the work area checkout appointment.

Any mixture or pure or substance which is or contains any of these elements or compounds is to be identified in the samples list by adding the name(s) of the element(s) or compound(s). Note that a few are rather common metals and solvents.
