Gas safety cabinets are designed to provide a safe and
cost-effective means of isolating hazardous gas cylinders from the
surrounding workplace.
The primary purpose of gas cabinets is to contain potential leaks
in piping and fittings at the cylinder connection. The cabinet must
be exhausted by a specifically designed fan and exhaust system. The
cabinet exhaust system draws leaking hazardous gasses out of the
cabinet. In the case of a flammable gas the cabinet will contain
the flame for a period of time. One can use a newly reconditioned
cabinet as well as non-reconditioned used gas cabinets depending on
their requirements.
No matter the type, size, or specifications of the storage cabinets
you buy, some aspects are non-negotiable.
▪Cabinets must provide a mechanism for securing gas cylinders in
place, preferably in an upright position (i.e. racking system or
chain).
▪Cabinets need to be stored in a dry location, outside and above
ground, and away from ventilation systems, direct sunlight, and
combustible or corrosive materials.
▪If stored inside, keep storage cabinets on the ground floor, never
on upper floors or in the basement, and away from air ducts,
internal windows, or other ventilation systems.
▪Cabinets need to be out of high traffic areas where they will not
be bumped or jostled.
▪Cabinets must have locking mechanisms.
▪Objects should not be stored on top of the storage cabinets.
▪Signs should be prominent around the storage cabinets to make
employees aware of the potential hazards of the space.

The gas cabinets are categorized into four popular types based on
the type of gas. The categories are:
Manual
These gas cabinets are used for inert, non-reactive and non-toxic
gases. There are automatic gas cabinets also available and thus
these cabinets are less useful when compared to automatic cabinets.
Fully automatic
These cabinets are available for corrosive, toxic and reactive
gases. They provide safe and clean delivery of ultra-high purity
gases. Such systems are designed to monitor a huge number of
facility inputs and process sensors as per requirements.
Auto changeover
These gas cabinets are useful when uninterrupted gas flow is
required. Auto changeover gas cabinets can be defined by mass or
pressure inputs. There is software also available for multiple
cylinder scales on each joint or bank. Purge down and purge up
processes can also be performed without any interruption of
connected cylinders.
The materials used to construct the gas cabinet are an important
part of proper system selection. The materials used for the casing
and outer parts must have adequate structural strength, while the
materials for the gas handling components must be compatible with
the media, temperature requirements, and pressure ratings to
prevent leakage, rupture, or contamination.
Aluminum
A light and fairly corrosion resistant metal which is most often
anodized for increased corrosion and wear resistance. Aluminum is
never used for tubing or fittings in modern industrial gas control
& distribution systems since 316L stainless steel (optimum
choice) is so available. Aluminum is not an ideal choice for
purity. Aluminum in any form is never used for ultra pure
industrial gas systems.
Copper
A soft, ductile metal with low hardness and excellent corrosion
resistance. Copper is used commonly in tubes and pipes for its
inertness and resistance to corrosion. Copper can be used for low
air, oxygen and other inert non-critical gases such as medical CFOS
systems. For ultra pure gasses 316L Stainless steel remains the
optimum choice for many reasons.
Plastic
Any of numerous thermoplastic or thermosetting polymers of high
molecular weight. Different grades (such as nylon, acetal, and
polycarbonate) have varying properties, but most have strong
chemical and corrosion resistance.
Steel
General purpose industrial metal with high physical strength and
hardness. Steel is typically coated or finished to increase its
corrosion resistance properties. Steel is used in the petroleum and
petro-chemical industries.
Stainless steel
316L Stainless steel became industry standard for fittings, piping
and controls in gas cabinets and distribution systems in the early
1980s. The material is further improved by electropolishing to
render wetted surfaces extremely impervious to the most reactive
gasses creating a non-shedding surface. A large industry has grown
around supplying these ultra-specialized components and materials.
