Storage and handling

Elements are filled with glycerin when new as part of the fiber manufacturing and preservation process. Elements must be stored in a dry and normally ventilated location, away from any sources of heat, ignition, and direct sunlight in the original packing. The storage temperature must be between 5°C and 35°C (45°F to 91°F).
