You see another stockroom worker or professor violating a safety rule.
Call them out, help them back to the world of compliance. Don't take excuses
How long can you continue to wear gloves after you get Acetone/Ethanol/ Nitric Acid on your gloves?
Not very long at all!
These will break down Nitrile gloves in less than a minute
A research lab worker comes to the window with a full waste container.
Its inspection time!
1) is it below the max fill?
2) has it been vented for 8 hours?
3)label adds up to 100%, label is legible, label is completely filled out
4) Generally clean
if so
1) initial the top right of the label
2) checkmark in top left corner to indicate you checked those 4 things.
3) put container in solvent room waste area
give them a replacement waste carboy and waste label if needed.
A student needs to replace a 600ml glass beaker, but the shelves are all empty.
We have more in 103 and above the Hand helds.
A student has HCl on their hands.
what do we ask?
what do we do?
Were you wearing gloves? was it part of your lab? did you wash your hands, for how long? does it burn or itch? did you get it on your clothes? did the spill get cleaned up? is there broken glass?
Fill out incident report include what you did to treat the student., make sure student is stable, and the area has been rinsed with diwater for atleast 15 minutes and there is not HCl on clothes
You break a volumetric flask while bending over to get a scoopula.

You are asked to reconcile the Goods Receipts and Purchase orders.
what is that and how do you do it?
Comparing purchase orders to things we received (goods receipt)
Highlight the items on the purchase order that we received, also mark it off on the GR, and file both in their respective binders behind "checked in"
A room (research or teaching lab) is in need of a new broken glass box.
Is box chemcial contaminated? Biological contaminated?
if not then is it less than 3/4ths full?
if so then the liner can be carefully tied closed, box taped shut, and thrown in the dumpster.
If more than 3/4ths full or have items protruding, will need to be broken down (wear cutproof gloves, goggles, and face shield)
A student from O. Chem II comes to the window saying a stir bar fell into the waste container.
Get the long stir bar retriever, retrieve stir bar, charge $5 for the service, remind student and IA to use the strainer.
wipe the stirbar and retriever clean
You wore gloves and goggles for this right?
A wash bottle in the lab is filled with a clear liquid. you are pretty sure its water. What do you do?
1) return to stockroom with bottle and make a note asking what it is and where it was found.
2) dump the contents into waste and rinse the bottle
3) Figure out what it is and label it accordingly
A student has rented goggles and is returning them
Clean the goggles with 70% ethanol, give student back their ID
How/ When do you log your hours?
on SAP. Check your assignment is correct, log SR hours Before Friday at Noon weekly. You can log your IA hours however you want, log the SR hours each week.
Do NOT go over 8 hours a day or 25 hours a week, even if we really need it.
Quant waste container in CHEM 327 is full.

An IA has not checked out their bin for their section that starts in 5 minutes.
Sucks when someone is cutting it close getting to work huh???
Check to see if they are in the lab and forgot or if they're running late. If late provide coverage if possible until they arrive. If not notify the coordinator.
How do you answer the phone?
Good afternoon, this is Carlos ihn the TXST Chem Stockroom, how can I help you today,
or something else that is equally cheery and informative
119 has a spill from the large 100L drum.
This could be a big spill.
is it something you can stop and clean up on your own? If its more than 20L on the floor you better call in the cavalry (EHSREM).
Otherwise try to stop the leak, clean it up or neutralize if possible, disose of pig pads by bagging and tagging, giving over to EHS. notify Carlos.
What are the morning opening procedures?
What are the evening closing procedure?
ACS, lock/unlock labs, prep hand helds, check waste and ethanol. Open/close window, check labs for cleanliness
Neutralizing and drain disposing waste.
when can we neutralize and drain dispose waste?
what is the Acceptable pH?
If EHSREM has approved the waste profile for drain disposal. Beers law, gas law, titrations are waste streams that can be neutralized and drain disposed. Can not contain ethanol. Record date waste was drain disposed, volume disposed, and pH of waste.
Ph Range preferred 7-9, 6-11 is the waste permit. (aquifer water tend to be basic)
Biology department comes by to get 15 gallons of ethanol
Pump it! Record the PO# on the top of the receipt they give us and the amount dispensed. put receipt on Carlos' desk
What do you do after using the microwave?
Clean it! Even if its just used to heat water!
