Section 7. Handling and storage
: Do not ingest. Do not puncture or incinerate container. Wash thoroughly after handling.
Handling
High pressure gas. Use equipment rated for cylinder pressure. Close valve after each
use and when empty. Protect cylinders from physical damage; do not drag, roll, slide, or
drop. Use a suitable hand truck for cylinder movement.
: Keep container tightly closed. Keep container in a cool, well-ventilated area. Cylinders
Storage
should be stored upright, with valve protection cap in place, and firmly secured to
prevent falling or being knocked over. Cylinder temperatures should not exceed 52 癈
