Department of Chemistry - Health and Safety Information

Use of malodorous materials ('nasty niffs')

The use of malodorous thiols and mercaptans (particularly those that smell of gas) MUST be notified to the Department prior to work commencing. All use of thiols, work ups of thiol reactions and disposal of solutions i.e. when any reaction mixtures that have been destroyed (by oxidation with bleach) are disposed of via the drain MUST be reported. When working with thiols and mercaptans, ensure that your reaction is aspirated through an in-line bleach bath (dreschel bottle).

If you are reporting a strange smell in the building, please telephone Reception (network telephone 36300).

To notify your intended use of malodorous chemicals, please complete the online form which will automatically email the chem-nasty-niffs@lists.cam.ac.uk list with all the required information.
