Conditions of storage and transport shall be such that the integrity of the product container and the safety and quality of the product are not adversely affected. Attention is drawn to common forms of damage such as that caused by improper use of fork lift trucks.

Warm metal containers should not be stacked so as to form incubation conditions for the growth of thermophilic organisms.

High humidity storage should be avoided. Metallic containers kept at high humidity particularly for a long time and especially in the presence of mineral salts or substances which are even very weakly alkaline or acidic are likely to corrode.

Labels or label adhesives which are hygroscopic and therefore liable to promote rusting of tinplate should be avoided as should pastes and adhesives that contain acids or mineral salts.

Cases and cartons should be thoroughly dry. If they are made of wood it should be well seasoned. They should be of the proper size so that the containers fit snugly and are not subject to damage from movement within the case. They should be strong enough to withstand normal transportation.

Metal containers should be kept dry during storage and transportation. The mechanical properties of outer cartons etc. are adversely affected by moisture and the protection of the containers against transport damage may become insufficient.

The storage conditions, including temperature, should be such as to prevent deterioration or contamination of the product. Rapid temperature changes during storage should be avoided as this may cause the condensation of moist air on the containers and thus lead to container corrosion.
