3 Hazards identification
Classification : R8 Contact with combustibles may cause fire
Emergency Overview : High pressure compressed gas. Can cause damage to lungs and central nervous system. High concentrations may cause asphyxiation
Inhalation : Breathing 75% or more oxygen for more than a few hours may cause stuffiness, cough, sore throat, chest pains and breathing difficulties.
Aggravated medical : Do not administer to persons with chronic obstructive pulmonary disease.
4 First aid measures
Inhalation : Remove victim to fresh air wearing self contained breathing apparatus. Keep victim warm and rested. Apply artificial respiration if breathing has stopped.
Ingestion : Ingestion is not considered a potential route of exposure
Eye contact : Seek medical advice.
5 Fire-fighting measures
Extinguishing media : All known extinguishing media can be used.
Specific hazards : Upon exposure to intense heat or flame, cylinder will vent rapidly or rupture violently. Product is non-flammable and does not support combustion. Move away from container and cool with water from a protected position.
Protective equipment : Wear self-contained breathing apparatus for fire fighting if necessary.
Further information : Some materials that are non-combustible in air will burn in the presence of an oxygen enriched atmosphere (greater than 23%). Fire resistant clothing may burn and offer no protection in oxygen rich atmospheres.
6 Accidental release measures
Personal precautions : Evacuate the area. Monitor oxygen level and ventilate the area. Unless atmosphere is safe, wear self contained breathing apparatus. Clothing exposed to high concentrations may retain oxygen for 30 minutes or longer. Stay away from ignition sources.
Environmental precautions : Try to stop release. Prevent from further leakage if safe to do so. Do not discharge into low areas (e.g. basements)
Clean up methods : Ventilate the area.
7 Handling and storage
Handling : Open valve slowly. Do not allow backfeed into the container. Do not remove safety labels. Always use with specified equipment fit for purpose
Storage : Keep container in a well ventilated area. Store cylinder below 50°C
See reverse for further handling, usage and storage guidelines
8 Exposure controls/personal protection
Exposure controls : Wear eye protection to EN 166 when using gases. Wear leather safety gloves free of oil or grease and safety shoes when handling cylinders.
Personal protection : Ensure adequate ventilation.

11 Toxicological information
Premature infants exposed to high concentrations may suffer delayed retinal damage that can progress to retinal detachment and blindness. Retinal damage may also occur in adults exposed to 100% oxygen for extended periods. At two or more atmospheres central nervous system (CNS) toxicity occurs. Symptoms include nausea, vomiting, vertigo, muscle twitching and loss of conciousness. At three atmospheres CNS occurs in less than two hours and at six atmospheres in only a few minutes.
12 Ecological information
No known ecological effects from this product
13 Disposal considerations
Return cylinders to the supplier (used and unused)
14 Transport Information
Proper Shipping Name : Oxygen Compressed
UN ID no. : UN1072
Labelling ADA : 2.2 : 5.1
