PHYSICAL AND CHEMICAL PROPERTIES
Appearance
Colourless gas. *
Do not store cylinders in vehicles – remove them once
the destination is reached.
Oxidising Properties
More oxidising than air.
Fire-fighting equipment should be carried.
Odour
None.
Relative Density (gas)
Heavier than air
Only use vehicles where the load is segregated from
the driver’s compartment.

None.
Extra regulations apply to vehicles carrying large
quantities of dangerous substances.
Relative Density (liquid) N/A

* Cold gas may appear white due to ‘fogging’ of
surrounding air.
STABILITY & REACTIVITY
Possibility of violent reaction with reducing agents or
combustible materials. Impregnated clothing may
readily be ignited. The gas strongly supports
combustion. All pipe work and ancillary equipment
should be prepared for Oxygen duty.
Contact CryoService for information concerning these,
or for other transportation information.

HAZARDS IDENTIFICATION
Oxidant gas under high pressure.
Skin
High-pressure release may cause
injury.
Eyes
High-pressure release may cause
injury.
Inhalation
May have adverse effects (sources
differ).
ACCIDENTAL RELEASE MEASURES
Personal
Evacuate area. Wear suitable
protective clothing. Wear selfcontained breathing apparatus if it is
necessary to enter the area.
Environment
Close the valve, and/or remove
container to the open air if safe to do
so. Prevent from entering basements,
workpits, sewers and other low lying
areas where accumulation could be
dangerous.
HANDLING AND STORAGE
Only trained personnel should handle or use cylinders.
Do not subject cylinders to excessive heat, cold or
mechanical shock.
Store cylinders out of doors or in a well-ventilated place.
Prepare and implement a procedure to deal with any
emergency.
Obey all in-house and statutory regulations.
FIRST-AID MEASURES
Eye contact
Immediately flush eyes thoroughly with
tepid water for at least 15 minutes.
Obtain medical assistance.
Skin contact
Immediately flush the affected area
with tepid water for at least 15
minutes. Obtain medical assistance.
Inhalation
Symptoms may include loss of mobility/
consciousness. Using self-contained
breathing apparatus, remove casualty
from exposure. Call a doctor. Keep
casualty warm and rested. If breathing
has stopped, apply artificial respiration.
FIRE-FIGHTING MEASURES
Ensure that the emergency services are aware of the
presence of gas cylinders on the premises.
If more than one gas or mixture is kept, ensure that they
can be readily identified.
Use only equipment suitable for the gas(es) and
pressure involved and inspect regularly. CryoService
Limited offer a range of regulators and fittings.
Cylinders without valve guards are shipped in
crates;retain these for later use. Do not remove valve
guards where fitted.
Do not remove labels from cylinders or crates (except
the return address cover).
Do not lift cylinders by the valve.
Use suitable cylinder handling and securing equipment.
Do not use oil or grease on valves, fittings, or any other
equipment.
Always close valves using moderate force only, even
when the cylinder is empty.
Do not attempt to control the gas flow using the valve.
Extinguishing
media
None required for gas or cylinder.
Specific
method
If there is no risk, close valve and
remove container from affected area.
Where container cannot be removed,
every effort should be made to keep it
cool by spraying with large quantities
of water from a protected position.
Specific
hazard
Protective
equipment
Supports combustion.
The container may rupture violently if
heated. Non-flammable.
In confined spaces use self-contained
breathing apparatus.
Use a suitable regulator.
Fit a non-return system if there is any risk of back-flow
into the cylinder.
Always ensure that the system being pressurised has a
suitable outlet.
Liquid cylinders (e.g. LPG) should be kept upright
Do not transfer this gas into another cylinder by
decantation or re-pressurisation.
Return empty or unwanted cylinders promptly.
EXPOSURE CONTROLS/PERSONAL
PROTECTION
Be aware of high pressure release.
Ensure adequate ventilation.
Wear gloves, eye protection and safety footwear when
handling cylinders.
Keep appropriate safety equipment in the working area.
