Understanding Liquid Helium(HE)
What is Liquid Helium?
Liquid Helium is non-corrosive, odorless, colorless, inert, inflammable, and
extremely cold. Helium does not react with other elements under ordinary
conditions. As helium is non-corrosive, special construction materials are not
required. However, construction materials should only be used if they are
suitable to be used with the extremely low temperatures of liquid helium.
Vessels and pipings must be designed and selected to withstand the
temperature and pressure that is involved and comply with applicable codes
for use and transport.
What are the uses of Liquid helium?
As liquid helium has an extremely low temperature, it is used to maintain the
properties of a super-strong magnet in applications like NMR, MRI, particle
physics research, and spectroscopy. The most common use of liquid helium is
that it acts as an inert shielding gas in laser welding and metal arc. It gives a
protective atmosphere in the production of reactive metals.
What are the health effects of liquid helium?
Liquid HE is tasteless, colorless, odorless and non-irritating therefore it has no
warning properties. Human beings do not have the sense to identify the
presence of helium in the atmosphere. Though helium is inert and non-toxic,
it might act as an asphyxiant by eliminating the oxygen from the air. It can
cause the oxygen level to reduce to the level below than what is required to

support life. When inhaled in excessive amounts, helium can cause vomiting,
nausea, dizziness, loss of consciousness, and in some cases death also. Death
can be the result of confusion, loss of consciousness, or errors in judgment
that do not let the person rescue. A low concentration of oxygen causes death
within seconds and without warning. People should not enter in an area
having oxygen concentration levels less than 19.5% unless they are provided
with a self-contained breathing apparatus or air-line respirator.
Liquid Helium is becoming a precious commodity and many users of this are
now trying to recycle their helium and reuse it in their process in a closed
loop. MVS, in partnership with world leaders in this field – Cryomech, USA,
offer liquid helium recovery and recycling systems which can save our
customers tremendously in the long run.
