What Does Container Mean?
According to OSHA regulations, a container is "any bag, barrel, bottle, box, can, cylinder, drum, reaction vessel, storage tank, or the like, that contains a chemical hazard. For purposes of the section, pipes or piping systems, and engines, fuel tanks, or other operating systems in a vehicle, are not considered to be containers." This definition comes from the OSHA Hazard Communication Standard at 29 CFR 1910.1200. It should be noted, however, that some state 'right to know' laws do consider pipes to be containers.
