AUTHORISED PERSONS ONLY AREA
- All procedures requiring the use of these laboratories must abide by the Health and Safety regulations of COSSH and Risk Assessment, which must be studied before commencing work.
- New students, staff, or visitors must not commence work in the laboratories until after instruction has been given in the correct safety procedures for the instruments and chemicals involved.
- Before entry into either of the clean chemistry laboratories (N24 or S424), full polypropylene suits supplied must be worn; for type see Appendix 1.
- Correct carriers must be used to move Winchesters of acids between Laboratories.
- The fume cupboards in the clean chemistry laboratories (N24 and S424) are polypropylene specialist cupboards of low airflow design, as also are the clean preparation perspex chambers in S416A. They must not be used as general fume cupboards. NO naked flames or high temperatures are permitted.
- The extraction fans for the fume cupboards in rooms S416A, S424, N24 must be left on at all times. In the event of a power failure, proceed with caution and report to the safety person for the section. The fume cupboards will remain off and their mains switches must be reset and retested as per the maintenance procedure for each cupboard.
- The fume cupboard safety windows in the clean chemistry laboratories, S424 and N24 are moved up using the security pegs to hold the sash open, they should then be returned to the lower position. The lower safety sash peg positions act as wrist and finger protectors, and must always be in place.
- The use of HF is permitted only in room N24. It must not be used in any of the other laboratories. HF may only be used after full safety instruction and compliance to COSSH and Risk Assessment has been carried out by the Head of Section or the Local Officer for Safety. Separate, detailed instructions for the use of HF are provided (see Appendix 3).
- Perchloric acid must not be used in any of the laboratories.
- Disposal of waste chemicals. After gaining permission from the Local Officer for Safety, acids for disposal (excluding HF) should first be diluted to less than 10% concentration, after which they may be poured down the sink and rinsed away with a large excess of water. For disposal of other chemicals, refer to Appendix 5 and the University Guidance for Discharges to Drains, a copy of which is in the Library.
- The infra-red lamps should not be switched on until the fume cupboard safety sash has been lowered. The hot lamp bulbs will explode if they come into contact with liquid. Therefore, do not dispense reagents in the evaporator cabinets.
- Pressure vessels for dissolution of rock powders and minerals in room N24 must never be opened when hot. Allow them to cool before unscrewing the metal case and always open the Teflon inner jacket in the fume cupboard.
- The microwave digestion system in room N24 may only be used by authorised personnel and after proper instruction.
- The Mass Spectrometer (Room S417) must not be adjusted or touched by any unauthorised persons. Everyone, including visitors to the lab, must be warned when the EHT is at high volts (8000V). Refer to Appendix 6 for the safe use of liquid nitrogen before filling this machine.
- Out of hours working: see Appendix 2.
- For use of ultraviolet light, see Appendix 7.
