below 200 deg. F (93.3 deg. C), except any mixture having components with
flash points of 200 deg. F (93.3 deg. C), or higher, the total volume of which
make up 99 percent or more of the total volume of the mixture.
Compressed gas
Any compound that exhibits:
• A gas or mixture of gases having, in a container, an absolute pressure
exceeding 40 psig at 70 deg. F.
• A gas or mixture of gases having, in a container, an absolute pressure
exceeding 104 psig at 130 deg. F. regardless of the pressure at 70 deg.
F.
• A liquid having a vapor pressure exceeding 40 psig at 100 deg. F.
Container
Any bag, barrel, bottle, box, can, cylinder, drum, reaction vessel, storage
tank, or the like that contains a hazardous chemical. For purposes of this
section, pipes or piping systems, and engines, fuel tanks, or other operating
