17 Freezers, refrigerators & controlled temperature rooms
17:1 None of the departmental freezers, refrigerators and controlled temperature rooms are spark proof so volatile or materials containing volatile solvents must not be stored in these areas as there can be a risk of explosion due to vapours being ignited from sparks generated by thermostats and compressors.
17:2 The controlled temperature rooms are virtually airtight boxes so the use of techniques and materials that result in the release of toxic, flammable or suffocating vapours (e.g. Cardice or liquid nitrogen) to the atmosphere are particularly dangerous and must be avoided.
17:3 Use insulated gloves when removing materials from the -70oC freezers to prevent damage to the skin of the hands.
