The Compressed Gas Association (CGA) is an American trade association for the industrial and medical gas supply industries. [2]

Contents

The CGA publishes standards and practices that codify industry practices. In cases where government regulation is inspecific, CGA documents are considered authoritative. CGA falls into a group of trade associations whose publications are relied on by government. These groups include the National Fire Protection Association (NFPA) and ASTM International. For example, the state of Montana, the U.S. Army, and OSHA point to CGA documents for regulatory guidance. [3] [4]

Cylinder valve openings

The CGA provides detail specifications for the outlet connections of gas containers. They are based on the storage pressure and characteristics of the gas such as flammability, toxicity, state (permanent gas or liquefied) and corrosiveness. These connections are identified by a 3-digit number, such as CGA-555. The range of available connection standards covers the majority of the range of industrial, ultra-pure and medical gases in use, including the medical pin index safety system, scuba cylinder valves and liquefied natural gas for home use. [5]

The standards include:

Nitrox refers to any gas mixture composed of nitrogen and oxygen that contains less than 78% nitrogen. In the usual application, underwater diving, nitrox is normally distinguished from air and handled differently. The most common use of nitrox mixtures containing oxygen in higher proportions than atmospheric air is in scuba diving, where the reduced partial pressure of nitrogen is advantageous in reducing nitrogen uptake in the body's tissues, thereby extending the practicable underwater dive time by reducing the decompression requirement, or reducing the risk of decompression sickness .The two most common recreational diving nitrox mixes are 32% and 36% oxygen, which have maximum operating depths of about 110 feet and 95 feet (29 meters respectively.

Liquefied petroleum gas, also referred to as liquid petroleum gas, is a fuel gas which contains a flammable mixture of hydrocarbon gases, specifically propane, n-butane and isobutane. It can sometimes contain some propylene, butylene, and isobutene.

<span class="mw-page-title-main">Diving cylinder</span> Container to supply high pressure breathing gas for divers

A diving cylinder or diving gas cylinder is a gas cylinder used to store and transport high pressure gas used in diving operations. This may be breathing gas used with a scuba set, in which case the cylinder may also be referred to as a scuba cylinder, scuba tank or diving tank. When used for an emergency gas supply for surface supplied diving or scuba, it may be referred to as a bailout cylinder or bailout bottle. It may also be used for surface-supplied diving or as decompression gas. A diving cylinder may also be used to supply inflation gas for a dry suit or buoyancy compensator. Cylinders provide gas to the diver through the demand valve of a diving regulator or the breathing loop of a diving re-breather.

<span class="mw-page-title-main">Diving air compressor</span> Machine used to compress breathing air for use by underwater divers

A diving air compressor is a breathing air compressor that can provide breathing air directly to a surface-supplied diver, or fill diving cylinders with high-pressure air pure enough to be used as a hyperbaric breathing gas. A low pressure diving air compressor usually has a delivery pressure of up to 30 bar, which is regulated to suit the depth of the dive. A high pressure diving compressor has a delivery pressure which is usually over 150 bar, and is commonly between 200 and 300 bar. The pressure is limited by an overpressure valve which may be adjustable.

Bottled gas is a term used for substances which are gaseous at standard temperature and pressure (STP) and have been compressed and stored in carbon steel, stainless steel, aluminum, or composite containers known as gas cylinders.

<span class="mw-page-title-main">Gas cylinder</span> Cylindrical container for storing pressurised gas

A gas cylinder is a pressure vessel for storage and containment of gases at above atmospheric pressure. High-pressure gas cylinders are also called bottles. Inside the cylinder the stored contents may be in a state of compressed gas, vapor over liquid, supercritical fluid, or dissolved in a substrate material, depending on the physical characteristics of the contents. A typical gas cylinder design is elongated, standing upright on a flattened bottom end, with the valve and fitting at the top for connecting to the receiving apparatus.

<span class="mw-page-title-main">Lockout–tagout</span> Safe isolation of dangerous equipment during maintenance or testing

Lock out, tag out or lockout–tagout (LOTO) is a safety procedure used to ensure that dangerous equipment is properly shut off and not able to be started up again prior to the completion of maintenance or repair work. It requires that hazardous energy sources be "isolated and rendered inoperative" before work is started on the equipment in question. The isolated power sources are then locked and a tag is placed on the lock identifying the worker and reason the LOTO is placed on it. The worker then holds the key for the lock, ensuring that only that worker can remove the lock and start the equipment. This prevents accidental startup of equipment while it is in a hazardous state or while a worker is in direct contact with it.

<span class="mw-page-title-main">Industrial gas</span> Gaseous materials produced for use in industry

Industrial gases are the gaseous materials that are manufactured for use in industry. The principal gases provided are nitrogen, oxygen, carbon dioxide, argon, hydrogen, helium and acetylene, although many other gases and mixtures are also available in gas cylinders. The industry producing these gases is also known as industrial gas, which is seen as also encompassing the supply of equipment and technology to produce and use the gases. Their production is a part of the wider chemical Industry.

An oil terminal is an industrial facility for the storage of oil, petroleum and petrochemical products, and from which these products are transported to end users or other storage facilities. An oil terminal typically has a variety of above or below ground tankage; facilities for inter-tank transfer; pumping facilities; loading gantries for filling road tankers or barges; ship loading/unloading equipment at marine terminals; and pipeline connections.

<span class="mw-page-title-main">Pin Index Safety System</span> Component of medical gas supply systems

The Pin Index Safety System (PISS) is a means of connecting high pressure cylinders containing medical gases to a regulator or other utilization equipment. It uses geometric features on the valve and yoke to prevent mistaken use of the wrong gas. This system is widely used worldwide for anesthesia machines, portable oxygen administration sets, and inflation gases used in surgery.

An asphyxiant gas, also known as a simple asphyxiant, is a nontoxic or minimally toxic gas which reduces or displaces the normal oxygen concentration in breathing air. Breathing of oxygen-depleted air can lead to death by asphyxiation (suffocation). Because asphyxiant gases are relatively inert and odorless, their presence in high concentration may not be noticed, except in the case of carbon dioxide (hypercapnia).

The ROTAREX Group is a privately owned Luxembourgish group of companies who develop and manufacture high pressure valves, tube fittings and pressure regulators for almost all types of gas, in almost all application fields. Founded in 1922, under the name CEODEUX in Lintgen, Luxembourg, ROTAREX currently employs approximately 1600 people and is present on all continents with a broad range of products.

The British Compressed Gases Association is the UK's trade association for companies in the industrial, medical and food gases industry. BCGA was established in August 1971, succeeding the British Acetylene Association, which was formed in 1901.

The American Standard Safety System, or ASSS, is a connection system for gas cylinders with a volume exceeding 25 cubic feet. The connections differ in thread type and size, right and left-handed threading, internal and external threading, and nipple-seat design. This variability reduces the risk of errors such as administering the wrong gas to a patient, or utilizing equipment calibrated for one gas with another. However, as there are only 26 connections for the 62 gases and mixtures recognized by the CGA, connections are not unique.

Several types of valve connections for propane, butane, and LPG containers exist for transport and storage, sometimes with overlapping usage and applications, and there are major differences in usage between different countries. Even within a single country more than one type can be in use for a specific application. This requires adequate tooling and adapters for replenishment in multiple countries. For example for overlanders and users of autogas traveling with a container originating in one country to other parts of the world this is a major concern. This article describes existing standards and the standards in use for a number of countries. For disposable containers the availability per country is described. Filling stations may be able and allowed to fill foreign containers if adequate adapters are available. Adapters are provided by, amongst others, camping stores. The iOverlander database maintained by travelers, My LPG and the Facebook group "Cooking Gas Around the World" provide more information about individual sources per country. Much general information about global LPG use and standardization is available from the World LPG Association and the AEGPL

<span class="mw-page-title-main">Scuba cylinder valve</span> Valve controlling flow of breathing gas into and out of a scuba cylinder

A scuba cylinder valve or pillar valve is a high pressure manually operated screw-down shut off valve fitted to the neck of a scuba cylinder to control breathing gas flow to and from the pressure vessel and to provide a connection with the scuba regulator or filling whip. Cylinder valves are usually machined from brass and finished with a protective and decorative layer of chrome plating. A metal or plastic dip tube or valve snorkel screwed into the bottom of the valve extends into the cylinder to reduce the risk of liquid or particulate contaminants in the cylinder getting into the gas passages when the cylinder is inverted, and blocking or jamming the regulator.
