It is recommended that steel storage tanks of suitable std be used ... Storage vessels should be fitted with temp gauges & automatic water sprays. ... All tanks & equipment must be earthed. Transfer of material by pipeline must be by pressure of nitrogen. ... Drums containing acetaldehyde should never be stored in direct sunlight or other warm areas.
PRECAUTIONS FOR "CARCINOGENS": Storage site should be as close as practical to lab in which carcinogens are to be used, so that only small quantities required for ... expt need to be carried. Carcinogens should be kept in only one section of cupboard, an explosion-proof refrigerator or freezer (depending on chemicophysical properties ...) that bears appropriate label. An inventory ... should be kept, showing quantity of carcinogen & date it was acquired ... Facilities for dispensing ... should be contiguous to storage area. /Chemical Carcinogens/
