Checklist for monthly lab jobs
The following are detailed instructions for lab jobs.
1. Check the solvent cabinet in Lab 152. Make sure there is adequate solvent in each 20 L/4 L container (methanol, acetone, hexanes,
ethyl acetate, dichloromethane, chloroform). Ether, Toluene, Ethanol, Acetonitrile and solvents like these that are used only in small
quantities, can be purchased in 4 L or appropriate size containers.
2. Check the status of spare solvents. At all times, there should be spare 20 L/4 L containers of hexanes and ethyl acetate (1 each),
which should be stored in the flammable cabinet.
3. Check the corrosive chemicals cabinets under the fume hoods/sinks and inorganic shelves. Make sure there is adequate amount of
commonly used acids (HCl, HNO3, H2SO4, CH3COOH), bases (NaOH, KOH, K2CO3, NaHCO3) and drying reagents (Na2SO4,
MgSO4).
4. When liquid and/or solid waste containers are full, label them properly and call for pickup.
5. Check that communal areas of the lab are clean and in good order, such as the balance area, the rotary evaporator tables.
6. By 4:00 pm Friday each week the solvents should be fully stocked, all full liquid and solid waste containers called in, and all empty
solvent and chemical containers disposed of.
For the people not on duty
Please be considerate. If you are not on duty this does not preclude you from the responsibility to keep the labs functional.
 Keep common work place clean and tidy. Don’t leave things lying around in communal areas; keep the balance area clean; keep the
common office areas clean and tidy; do not leave print-out lying on the printer; do not leave gloves and safety glasses on the
common desks.
 Do not leave 4L solvent bottles on the benches longer than required. Any closed 4L bottle on the bench is violation of UW
regulations. Please return to the yellow flammables’ cabinet as soon as done. Empty 4 L containers should be placed inverted in a
safe place to drain off residual solvents and leave them in the pickup place without the caps on. Keep the caps in carton boxes for
use with disposal of special waste. These should be removed from the inventory, if possible and the name of the solvent/chemical
and the barcode should be crossed through with a Marker pen.
 If you use the last of a common chemical available from the shelves (ammonium chloride, magnesium sulfate, sodium carbonate,
sodium hydroxide), either replace it from the stockroom or write in the ‘Requests’ box on the duties sheet.
 Label containers with the date when first opened.
 If possible use an already opened container in preference to a new one.
 Before ordering any chemical please double check the inventory database and make sure we do not have it. If you found we have it
and not in usable condition, quench/dispose it off appropriately before placing order for new one.
