### 4 FIRST AID MEASURES Inhalation In high concentrations may cause asphyxiation . Symptoms may include loss of mobility/consciousness . Victim may not be aware of asphyxiation . In low concentrations may cause narcotic effects . Symptoms may indude dizziness . headache , nausea and loss of

### co- ordination . Remove victim to uncontaminated area wearing self contained breathing apparatus. Keep victim warm and rested. Call a doctor. Apply artificial respiration if breathing stopped . Skin/eye contact For liquid spi llage - flush with water for at least 15 mi nutes Obtain medical assistance Ingestion Ingestion is not considered a potential route of exposure . 

### 5 FIRE FIGHTING MEASURES Specific hazards Exposure to fire may cause containers to rupture/explode . Hazandous combustion products Incomplete combustion may form carbon monoxide. Suitab le extinguishing media All known extinguishants can be used . Specific methods If possible . stop flow of product. Move container away or cool with water from a protected position . Do not extinguish a leaking gas flame unless absolutely necessary. Spontaneous/explosive reignili on may occur. Extinguish any other fire . Extinguish any dher fire . Special protective equipment for fire fighters In confined space use self-<:Ontained breathing apparatus . 6 ACCIDENTAL RELEASE MEASURES Personal precautions Wear self-<:Ontained breathing apparatus when entering area unless atmosphere is proved to be safe. Ensure adequate air ventilation . Evacuate area . Eliminate ign ition sources. Environmental precautions Try to stop release . Prevent from entering sewers, basements and workpits. or any place where its accumulation can be dangerous. Clean up methods Ventilate area . Keep area evacuated and free from ignition sources until any spilled liquid has evaporated. (Groundfree from frost). 7 HANDUNG AND STORAGE Handling and storage Ensure equipment is adequately earthed. Suck back of water into 

### the container must be prevented. Purge air from system before introducing gas . Do not allow 

### backfeed i nto the container. Use only proper1y specified equipment which is suitable for this product , its supply pressure and temperature . Contact your gas supplier if in doubt. Keep away from ignition sources (including static discharges) . Refer to supplier's container handling instructions . Prevent bottles from falling down. Segregate from oxidant gases and other oxidants in store . Keep container below 50"C in a well venti lated place . Observe "Technische Regeln Druckgase (TRG) 280 Ziffer 5"
