Cylinders, containers, and tanks must comply with the regulations set by the Department of Transportation (DOT), Transport Canada (TC), or the ASME Boiler and Pressure Vessel Code.
2. Cylinder Identification

- Liquid containers must have identification visible from all directions, with at least 2-inch high letters or a 360-degree wraparound tape.
- Outlet connections for cryogenic liquid containers must follow CGA V-5 or CGA V-1 standards.
- Outlet connections must be integral to the valve, unremovable with ordinary tools, or rendered unusable if removed.
- Labels must remain intact and unmodified.
3. Signage for Source Locations

NO SMOKING OR OPEN FLAME
ROOM MAY HAVE INSUFFICIENT OXYGEN
OPEN DOOR AND ALLOW ROOM TO VENTILATE BEFORE ENTERING
