Oxygen, compressed

Move the exposed person to fresh air at once.

Symptoms: Continuous inhalation of concentrations higher than 75% may cause nausea, dizziness, respiratory difficulty and convulsion.

Ingestion is not considered a potential route of exposure.

Water. Dry powder. Foam. Carbon Dioxide.

None.

Supports combustion. Heat may cause the containers to explode.

In case of fire: Stop leak if safe to do so. Continue water spray from protected position until container stays cool. Use extinguishants to contain the fire. Isolate the source of the fire or let it burn out.

Evacuate area. Eliminate all ignition sources if safe to do so. Provide adequate ventilation. Prevent from entering sewers, basements and workpits, or any place where its accumulation can be dangerous. Monitor the concentration of the released product.

Prevent further leakage or spillage if safe to do so.

Only experienced and properly instructed persons should handle gases under pressure. Use only properly specified equipment which is suitable for this product, its supply pressure and temperature. Keep equipment free from oil and grease. Open valve slowly to avoid pressure shock. Use only oxygen approved lubricants and sealants. Use only with equipment cleaned for oxygen service and rated for the pressure. Protect containers from physical damage; do not drag, roll, slide or drop. Secure cylinders in an upright position at all times, close all valves when not in use. When using do not eat, drink or smoke.

Keep container below 50°C in a well ventilated place. Store containers in location free from fire risk and away from sources of heat and ignition. Keep away from combustible material. Avoid asphalted locations for storage, transfer and use (ignition risk if spilt).

When using do not eat, drink or smoke.

Store containers in location free from fire risk and away from sources of heat and ignition. Keep away from combustible material. Avoid asphalted locations for storage, transfer and use (ignition risk if spilt).

Consider a work permit system e.g. for maintenance activities. Ensure adequate air ventilation. Avoid oxygen rich (>23,5%) atmospheres. Gas detectors should be used when quantities of oxidizing gases may be released. Provide adequate ventilation, including appropriate local extraction, to ensure that the defined occupational exposure limit is not exceeded. Systems under pressure should be regularly checked for leakages. Preferably use permanent leak tight connections (eg. welded pipes).

Wear working gloves while handling containers. Guideline: EN 388 Protective gloves against mechanical risks.

Wear eye protection to EN 166 when using gases. Guideline: EN 166 Personal Eye Protection.

Not required.

Body protection: No special precautions. Other: Wear safety shoes while handling containers. Guideline: ISO 20345 Personal protective equipment - Safety footwear.

For waste disposal, see section 13 of the SDS.

Stable under normal conditions.

No reactivity hazard other than the effects described in sub-section below.

Violently oxidises organic material. May react violently with combustible materials. May react violently with reducing agents.

None.

Combustible materials Reducing agents. Keep equipment free from oil and grease. For material compatibility see latest version of ISO-11114. Consider the potential toxicity hazard due to the presence of chlorinated or fluorinated polymers in high pressure (>30 bar) oxygen lines and equipment in case of combustion.

Under normal conditions of storage and use, hazardous decomposition products should not be produced.

Do not discharge into any place where its accumulation could be dangerous. Vent to atmosphere in a well ventilated place.

Refer to the EIGA code of practice (Doc.30 "Disposal of Gases", downloadable at http://www.eiga.org) for more guidance on suitable disposal methods.
