Storage Conditions：

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.
