Waste Disposal
• Put all waste into proper waste container
• If lab requires more than one waste bottle, educate the
students on each bottle’s contents
--If non-compatible substances are mixed in a waste
bottle, take the cap off, close the fume hood and call
stockroom for help!
Make sure nothing spills on the outside of the bottle
Stockroom can bring down a funnel if needed
Make sure waste bottles are closed between uses.
**CHM 226 TAs must constantly remind students to
dispose waste in proper containers, many chemicals
are incompatible
Waste Disposal & Labeling
Do not put anything but water in the sinks
All chemicals are to be disposed of in waste containers
*Note: Spill cleanup materials are also considered hazardous
waste … This includes contaminated clothing!!!
Waste labels must be kept neat
Make sure bottles have legible hazardous waste labels
If the label gets ruined, call the stockroom for a replacement
Chemical formulas may not be used on a hazardous waste label
DO NOT date waste bottles
DO NOT transfer waste between labs
Waste Labels & Containment
Make sure you have enough waste containers
– If not, call the stockroom to bring down a new container
before the old one is full
– Do not overfill waste containers.
**CHM 102/114 and 105 must monitor barrels, do not let
students overflow them! Call stockroom when they are getting
full!
All waste bottles must be in secondary containment
– Do not store incompatible wastes in the same containment
tray.
Lab Maintenance
•
•
•
•
•
Burets
Balances
Measurenet Stations
Hot Plates
Etc.
When you enter the lab:
Check the chemicals, lab equipment, waste bottles,
paper towels and any other communal items
When you leave the lab:
Turn off lab equipment and computers, check to make
sure waste isn't overflowing, shut windows, lock
doors and alarm the lab
Chemical Hazards
• Always be knowledgeable of the chemical
hazards present
• SDS information will be available in the lab
– Prior to the start of the lab familiarize yourself
with the SDS and GHS symbols associated with the
chemicals you will use in the lab
– For chemical injuries, give EMS the multi page SDS
that is located in the lab. SDS books are arranged
alphabetically
– The mini SDS with GHS symbols will also be
present for the experiment that week
Be familiar with NFPA Ratings & be able to explain them
to students
Global Harmonization System (GHS)

What is it?
Classifying and labeling chemicals

Health/physical/environmental hazards
https://www.osha.gov/dsg/hazcom/ghs.html
GHS Symbols
Chemical Spills
• If a small spill occurs
Use a spill pad to absorb it
If you need more spill pads to fully clean up the area,
call the stockroom to report the spill and get some
help.
• If the spill is large
Use the spill kit if necessary
Isolate the area
– Call the stockroom for help
– Dispose all spill pads & spill response materials in the
appropriate waste container.
What if my student is not on the
Roster?
•
Ask the student what section they believe they should
be in and make sure they are in the right room.
– Some students might be on the waitlist
• If student is waitlisted for your section have them
complete the safety training and circle “waitlist” on
their compliance form.
• If student missed their initial lab time have them
complete safety training, but make sure you write the
section number they’re suppose to be in on compliance
form and circle “makeup”
- Do not exceed the capacity of the room
Safety Training Makeups
Checking into Drawers
• Only assign drawers to students who are on the computer roster
– Circle “waitlist or makeup” on those student's compliance form
who are not on your computer roster
• Have students check their drawer for completeness. This means
take everything out and put back only what is on the equipment list.
What to do when done with
safety training
When finished:
Collect the compliance forms
Look over the completed compliance form before the student
leaves lab. Make sure it is correct and complete!
Immediately following class take ALL compliance forms to the
stockroom.
Note: account hold and
weekly emails to student's
email
Common Compliance Form Errors
•
•
•
•
•
•
•
•
Student didn’t write their name on plagiarism policy
Student didn’t write out the full date (mm/dd/yyyy)
Student checked boxes instead of initialing
Student used pencil instead of pen
TA didn’t write TA name on compliance form
Student didn’t initial billing bullet
TA wrote the wrong section
TA didn’t sign and date the compliance form
Pop Quiz!
How often will emails be sent to students about their bills?
Every week
What's the latest a student can pay their bill before getting a
hold on their account?
End of the semester
What is GHS and why is it important?
Global Harmonization System because it is a Federal Regulation
and is a global requirement.
Where can you find the GHS symbols for a specific chemical in
your lab?
SDS book
Plagiarism Forms
The Plagiarism form is on the back of the compliance
form! Make sure the student reads and signs it. This
is the department copy.
The student’s copy of the Plagiarism form is blue and
does NOT need to be handed in that is for the
student to read and keep.
Reporting M/B Equipment
If an item is found missing or broken within first 30min of Lab.
– Check to make sure item really is missing or broken
– Fill out MISSING/BROKEN request form online
– Send student to the stockroom immediately for a new item
In this situation the student will not be charged for said
missing/broken item as they have not used equipment yet.
If an item is found dirty, please have your student rinse it out with
water. If it can't be cleaned, put it through as broken. Students should
clean glassware when finished with experiment!
* TA should check all communal equipment in the lab for breakage prior to
the lab class. Be observant during your lab class and report any breakage of
communal equipment to the Stockroom (provide the student name and ID #
and description of broken equipment).
Avoiding Theft from Student Drawers
Inform CHM 226, 292 and 414 students that they “own” their drawer
contents for the semester
– Students are responsible for buying their own locks for 226 and
292
– The stockroom does not sell locks!
– The stockroom will open the departmental locks for the first
week only!
Rooms 101, 150, 151,160, 161,163, 165
– Remind all students to lock their drawers
– They will be held responsible for the contents of the drawers.
– All drawers have combination locks and students should be
given the combination during check-in
– Combinations to all in-use drawers can be found in TA Book
located in the TA drawer.
Stockroom Policies
• Stockroom Hours are 8am -5pm (Mon and Wed 8am to 8pm)
– If something is broken the TA should report the item via the online system and
the student should immediately come to the stockroom to replace the item.
– The stockroom does not accept cash
– Remind students that cash is only used during your graduate student sale of
the safety eyewear.
– A personal check can also be made out to the URI Chemistry Department
– Remind students to put money on their RAM account.
• See departmental policies or stockroom web page on how to do this
• Billing for broken/missing items will be posted via stockroom
webpage and weekly emails will be sent to the students
– Periodically show the bill list to the students
– Students receive a registration hold on their “e-campus account” if their bill(s)
are not paid
– Students may also have bills from previous semesters of which they will
receive an email
