Symptoms may <br />include loss of mobility/consciousness. Victim may not be aware of <br />asphyxiation. In low concentrations may cause narcotic effects. <br />Symptoms may include dizziness, headache, nausea and loss of co- <br />ordination. Remove victim to uncontaminated area wearing self <br />contained breathing apparatus. Keep victim warm and rested. Call a <br />doctor. Apply artificial respiration if breathing stopped. <br />Ingestion <br />Ingestion is not considered a potential route of exposure. <br /> <br />5 FIRE FIGHTING MEASURES <br />Specific hazards <br />Exposure to fire may cause containers to rupture/explode. <br />Hazardous combustion products <br />Incomplete combustion may form carbon monoxide. <br />Suitable extinguishing media <br />All known extinguishants can be used. <br />Specific methods <br />If possible, stop flow of product. Do not extinguish a leaking gas <br />flame unless absolutely necessary. Spontaneous/explosive re- <br />ignition may occur. <br />Special protective equipment for fire fighters <br />In confined space use self-contained breathing apparatus. <br /> <br />6 ACCIDENTAL RELEASE MEASURES <br />Personal precautions <br />Wear self-contained breathing apparatus when entering area unless <br />atmosphere is proved to be safe. Evacuate area. Ensure adequate <br />air ventilation. Eliminate ignition sources. <br />Environmental precautions <br />Try to stop release. <br />Clean up methods <br />Ventilate area. <br /> <br />7 HANDLING AND STORAGE <br />Handling <br />Ensure equipment is adequately earthed. Suck back of water into <br />the container must be prevented. Purge air from system before <br />introducing gas. Use only properly specified equipment which is <br />suitable for this product, its supply pressure and temperature. <br />Contact your gas supplier if in doubt. Keep away from ignition <br />sources (including static discharges). Refer to supplier's handling <br />instructions. <br />Storage <br />Secure cylinders to prevent them falling. Keep container below 50°C <br />in a well ventilated place. Segregate from oxidant gases and other <br />oxidants in store. Observe "Technische Regeln Druckgase (TRG) <br />280 Ziffer 5" <br /> <br />8 EXPOSURE CONTROLS/PERSONAL PROTECTION <br /> <br />Personal protection <br />Ensure adequate ventilation. Do not smoke while handling product. <br />Wear suitable hand, body and head protection. Wear goggles with <br />suitable filter lenses when use is cutting/welding. <br /> <br />9 PHYSICAL AND CHEMICAL PROPERTIES <br />General information <br />Appearance/Colour: Colourless gas. <br />Odour: Garlic like Poor warning properties at low concentrations. <br />Important information on environment, health and safety <br />Molecular weight: 26 g/mol <br />Melting point: -80,8 °C <br />Sublimation point: -84 °C <br />Critical temperature: 35,2 °C <br />Autoignition temperature: 325 °C <br />Flammability range: 2,4 %(V) - 88 %(V) <br />Relative density, gas: 0,9 <br />Relative density, liquid: Not applicable. <br />Solubility mg/l water: 1185 mg/l <br />Maximum filling pressure (bar): 19 bar <br /> <br />10 STABILITY AND REACTIVITY <br />Stability and reactivity <br />Can form explosive mixture with air.
