* Adapted from a presentation by Alex, Dan, Mark, and Karin

2. Safety orientation Hygiene Chemical storage and handling
Chemical waste stream
Sharps
Instruments and equipment
Accidents

13. Hygiene Food or water – NONE in lab spaces!
Hands should be washed upon entering and leaving the lab
Clothing
No open toed shoes
Avoid shorts and short sleeved shirts
Lab coat (discuss with your mentor when appropriate)
Backpacks and other belongings NOT ON FLOOR!
Safety gear
Eye protection is required at all times in the lab!!! (Visiting friends too!)
Gloves – worn when needed, never out of the labs
Hoods – keep the sashes lowered
Safety shields should be used when working with large volumes of solvents

14. Chemical storage and handling
At the bench
Label everything (Sharpies / pencils) – I’ll get us more if needed!!!
Understand the appropriate type of glassware to use (Erlenmeyers with volatile solvents)
Stoppered/secondary confinement when moving chemicals between/in labs
Keep reagent containers sealed
Balances – keep them clean
Hoods for volatile materials
MSDS – see Joanne Brown
Acids and bases must be kept separated
No more than 10 gallons of flammable liquid can be in one lab at any given time

15. Others
Peroxidizable chemicals – record the date on which the bottle was opened
Diethylether, THF, dioxane = dispose after 6 months
If you find an older bottle, a bottle the age of which you are unsure, or see the formation of solids on the covers of bottles for such compounds, seek assistance – DO NOT OPEN

16. Others Pyrophoric (spontaneously ignites in air)
n-BuLi, t-BuLi, others (always read all warnings on bottles!)
ONLY Rob will use t-BuLi if called for
Use n-BuLi ONLY after instruction from Rob or TA trained in its use; ask Rob about others
Handle and store under Ar! Wear appropriate labcoat!

17. Inventory Our chemical inventory, Vertere:
Joanne Brown is the administrator of our chemical inventory system
Empty bottles need to be triple rinsed and returned to Joanne for removal – please leave them in E108 in the appointed bin near the door
Please update the database to reflect movements in the locations of chemicals – note in stockroom on clipboard

18. Cryogens
Safety glasses (or better face shields) and thermal gloves must be worn.
Watch for the formation of liquid oxygen
(oxygen monitors)

19. Chemical waste stream
NOTHING down the sink (except dilute aqueous buffers or salts with Instructor permission)
Sharps containers – for syringes/needles with chemical residue in/on; NEVER recap a needle; NEVER put syringes/needles in the trash
Yellow tags are required to label waste for waste room disposal, with approximate compositions and amounts of the waste (from Joanne)
Organic solvents
moved daily to a secondary accumulation location
halogenated vs. non-halogenated
Solid waste containers

20. Sharps Broken glass – cardboard containers, no chemicals
Handing glass – stuck joints, inserting glass in anything – SEE ROB!
Syringes (including barrels) – red sharps containers – NEVER RECAP A NEEDLE!

21. Instruments and equipment
If you have questions, ASK – Study NMR tutorial on Moodle and work with your TA or Rob 1st before going it alone
Report problems (noises, alarms, leaks, smells..)
Gas tanks must be secured at all times
only moved on carts
only moved after the tops have been secures (never with a regulator)

22. Accidents Safety equipment Reporting accidents fire extinguishers
eye wash stations
showers
Reporting accidents
1. Use the buddy system
2. Routine issues – advisor
3. Potential health hazard – Security x1111 (phone in NMR Lab) or cell phone
NEAR system
Notify – Evacuate – Assemble – Report
Unusual event report
