Storage of Chemicals
- All chemicals must be stored in approved chemical cabinets according to their inherent properties and reactivity. All labs have access to ventilated chemical cabinets for storage.
- Incompatible chemicals, those that react together (e.g. acids /bases, oxidisers / reducers), must be stored separately. This means stored in a manner where spilled or leaked chemicals will not come into contact with other reactive chemicals. See Annex 8 for more information on incompatible chemicals
- Must be stored in ventilated flameproof cabinets.
- There is a flameproof cabinet in each lab, under the fume hood, where small to medium sized bottles and aliquots of flammable chemicals can be stored.
- Larger bottles should be stored in large cabinets outside of the lab (e.g. room 229 B1).
- Must be stored in a locked ventilated poison cabinet found in each lab.
- Remember to lock the cabinet after use!
- Storage of toxic substances in freezers and refrigerators: containers must be kept in a well-labelled secondary container, in an upright position.
- Must be stored in a ventilated cabinet.
- There is an acid / base cabinet under the fume hood in each lab
- Note that acid and bases are incompatible; store dry bases in the common base cabinet in room 228A1.
- Some organic and inorganic compounds react with oxygen in the air to form potentially explosive peroxides. Peroxide formation is accelerated when the substances are exposed to light and heat.
- Bottles containing peroxide-forming substances must be labelled “PEROXIDE-FORMING” and inspected for peroxide levels every 3 months after opening (see Annex 9 for label and more information).
- If a peroxide-forming substance has not been tested for 2 years: do not open or touch the bottles and treat it as an explosive substance.
