Other properties:

Cylinder pressure when full at 25 deg. C: 15,000 kPa approximately

Mixture of permanent and high pressure liquefiable gases, critical temperature not

determined.

Combustion reactions: Oil and grease can spontaneously ignite at low temperatures in

oxygen enriched atmospheres. Many other materials, which do not burn in air, will

vigorously burn in pure oxygen. Metals, once ignited, will burn in pure oxygen

atmospheres under specific conditions of temperature and pressure. Other Reactions:

Dust of aluminium, chrome and manganese ignite and explode when heated in carbon

dioxide. Incompatible with acrylaldehyde, aziridine, metal acteylides, sodium

peroxide.

Material compatibility: All non-metals must be oxygen compatible. Copper is most

commonly used metal. Carbon dioxide is corrosive when moist.

HEALTH HAZARD INFORMATION

Health Effects: Contains carbon dioxide at concentrations above its exposure

standard. Carbon dioxide LCLo mammal 5 minutes 90,000 ppm. May form oxygen

enriched atmospheres.



Acute: Unlikely effects from carbon dioxide or oxygen unless inhalation of mixture is

prolonged for several hours. The respiratory and central nervous systems are primarily

affected by gaseous oxygen. No health effects have been observed in humans exposed

to concentrations up to 80 volume % oxygen for a few hours or up to 50 volume % for

24 hours. At pressures above 1 atmosphere hyperoxia may appear after 2 to 6 hours.

Swallowed: No liquid phase.

Eye: Not irritating to the eye.

Skin: Not irritating to the skin.

Inhaled: Increased rate of breathing, respiratory irritation, choking feeling, headache,

confusion, exhaustion or unconsciousness. Other symptoms of hyperoxia include

cramps, nausea, dizziness, hypothermia, amblyopia (loss of vision), bradycardia,

fainting spells and convulsions capable of causing death.



Chronic: Exposure at normal or elevated pressure may cause severe thickening and

scarring of lung tissues. Carbon Dioxide is potentially toxic at concentrations below

3% due to cellular membrane effects and biochemical alterations such as increased

partial pressure of carbon dioxide, increased concentration of bicarbonate ions and

acidosis. Long term exposures to levels between 0.5 and 1% are likely to cause

calcium deposition in body tissues including kidneys. Not carcinogenic or mutagenic.



First Aid: Rescue personnel should be aware of extreme fire hazard in oxygen

enriched atmospheres.

Swallowed, Eye, Skin: Not applicable.

Inhaled: Remove from exposure. Check there is no obstruction to the airway if

breathing is weak or has ceased and give artificial respiration. Keep warm and rested.

Seek medical attention. Further treatment should be symptomatic and supportive.

First Aid Facilities: Air-Viva.



Advice to Doctor: Treatment for hyperoxia.

PRECAUTIONS FOR USE

Exposure Standards: Worksafe exposure standard TLV TWA for carbon dioxide is

5,000 ppm (0.5 volume %) STEL 30,000 ppm.



Engineering Controls: Do not expose cylinders to aggressive chemical or industrial

environment which will affect the integrity of the cylinder. Securely connect regulator

or manifold having suitable pressure and flow rating with connection to match

cylinder valve outlet. Never allow oil or grease on cylinder valves. Use only oxygen

compatible materials degreased for oxygen service. Copper, copper alloys and

stainless steel are recommended. Teflon is preferred. Most lubricants are not suitable.

Cylinder manifolds should be positioned in well ventilated areas, preferably outside a

building with low pressure gas piped to the inside. Mechanical lifting devices and

trolleys should be used to lift and move cylinders. Secure cylinders against falling at

all times, especially when in use. Ensure cylinder valve is shut and equipment

depressurised and purged with inert gas before commencing maintenance and repairs.



Personal protection: No smoking or naked lights. Check for leaks after pressurising

system and prior to starting any operation. Only experienced and properly trained

people should use this product. Wear safety glasses, safety shoes, use leather or cotton

protective gloves when handling cylinders. Open cylinder valve slowly to avoid

pressure shock and close when not in use.



 Flammability: Non-flammable product but vigorously supports combustion of

materials which will not usually burn in air. Concentrations of 25 volume % oxygen

will significantly increase the rate of combustion for some materials. Fires may start

easily due the reduced temperatures required to ignite materials in oxygen enriched

atmospheres.



SAFE HANDLING INFORMATION

Storage and Transport: Refer to Commonwealth, State and Territory Dangerous

Goods legislation which contain requirements for oxidising gas storage and transport.

Disconnect regulator and hoses before transporting or storing cylinders.

Store: Do not store near sources of ignition, poisons, flammable liquids or

combustible materials. Cylinders should be stored: upright, prevented from falling, in

a secure area; below 45 deg C, in a dry, well ventilated area constructed of non-

combustible material with firm level floor (preferably concrete), away from areas of

heavy traffic and emergency exits. Transport: Ensure cylinder is separated from driver

and that outlet of relief device is not obstructed. Shipping name: Carbon dioxide and

oxygen mixture, compressed. Transport E.P.G. card: 2C6.



Spills and disposal: Always ensure regulator is set to deliver a pressure below

equipment pressure rating and any relief valve setting. If a leak has occurred but

cannot be stopped by closing the cylinder valve then eliminate all sources of ignition,

remove cylinder outside to a well ventilated area and inform your nearest BOC Gases

centre. Never attempt to repair a leaking or damaged cylinder valve. Leak checking

may be done by pressure drop test, oxygen compatible leak detection fluid or oxygen

analysers at joints and outlets. Notify the nearest BOC Gases centre that you will be

returning a faulty cylinder. Residual product will be disposed of when the cylinder is

returned. Ensure the work area is thoroughly ventilated before re-use.



Fire/Explosion Hazard: Temperatures in a fire may cause cylinders to rupture and

internal pressure relief devices to be activated. Call fire brigade. This product will

vigorously support combustion. Do not approach cylinders suspected to be hot.

Remove cool cylinders from the path of the fire if safe to do so. Ensure working area

is well ventilated before re-use Notify the nearest BOC Gases centre that you will be

returning a faulty cylinder. Ensure the work area is thoroughly ventilated before re-

use.
