	Adjust button of gas cylinder of chair used as palm message - Patent 6416131
		The control valve of which is operated by gas pressure obtained throughout operation of valve pin via push button to provide the contraction movement of gas cylinder that results in the up and down movement of the seat enabling height of chair or slant of back to adjust to the body size of user.
		However, the conventional gas cylinder adopting push button type adjustment method is only directed to the one object, that is, for adjustment operation of height of chair and slant of back of chair.
		The push button means 300 connected to control valve of gas cylinder 200 formed on the arm rest 130 by the control rod 210 not only provides adjustment function to adjust the slant of back 120 and to adjust the height, but also provides the massaging function with the palm of hand.

	Gas Cylinder Safety
		Mechanical failure of the cylinder, cylinder valve, or regulator can result in rapid diffusion of the pressurized contents into the atmosphere, leading to explosion, fire runaway reaction, or burst reaction vessels.
		Gas cylinders may contain flammable, toxic, or corrosive gases; asphyxiants; or oxidizers.
		Keep the protective cap that comes with a cylinder of gas on the cylinder when it is not in use.

	Gas cylinder - Wikipedia, the free encyclopedia
		Often, gas cylinders are somewhat long and narrow and may stand upright on a flattened bottom at one end with the valve at the top.
		When the gas in the cylinder is ready to be used, the cap is taken off and a pressure-regulating assembly is attached to the stop valve.
		Gas cylinders are often color coded, but the codes are not standard across different jurisdictions, and sometimes are not regulated.

	COMPRESSED GAS SAFETY
		Gas Cabinets - With the exception of cylinders containing a non-toxic, flammable gas, and cylinders used in fume hood applications, hazardous gas cylinders must be housed in gas cylinder cabinets.
		For large cylinders a flow restricting orifice, installed by the gas supplier in the cylinder valve or installed in the gas purge panel is required.
		Failure to adequately purge cylinders can result in lack of ability to close the cylinder valve or "regulator creep" which allows full cylinder pressure to be transferred to the low pressure side of the regulator.

	Diving cylinder - Wikipedia, the free encyclopedia
		Diving cylinders are typically filled in the range of 186 to 300 bar (2700 to 4400 psi, or 18.6 to 30.0 MPa) and have a volume of 1.5 to 18 litres or a gas carrying capacity of 850 to 4200 litres (24 to 120 ft³).
		An especially common cylinder available at tropical dive resorts is an "aluminum-80" which is an aluminium cylinder rated to hold 80 ft³ of gas (at 1 bar) at its rated pressure of 3000 psi (i.e., its capacity is approximately 10 litres at 200 bar).
		Diving cylinders until the 1970s, before submersible pressure gauges on regulators came into common use, often used a mechanical reserve mechanism to indicate to the diver that the cylinder was nearly empty.

	ASU - Civil and Environmental Engineering - Lab Safety
		There are two types of hazards associated with the use, storage and handling of compressed gas cylinders: the chemical hazard associated with the cylinder contents (corrosive, toxic, flammable, etc.) and the physical hazards represented by the presence of a high pressure vessel in the laboratory.
		cylinders should be segregated in hazard classes while in storage, at the minimum, oxidizers (such as oxygen) must be separated from flammable gases, and empty cylinders should be isolated from filled cylinders.
		Leaking cylinders constitute a threat that may be so serious that entire facilities may be called on to evacuate and outside help may be required to assist.
