First-aid Measures General:  Never give anything by mouth to an unconscious person. If you feel unwell, seek medical advice (show the label where possible).

First-aid Measures After Inhalation:  First, take proper precautions to ensure your own safety before attempting rescue (e.g. wear appropriate respiratory protective equipment, use the buddy system), then remove the exposed person to fresh air. Keep at rest in a position comfortable for breathing. Obtain medical attention if breathing difficulty persists.

First-aid Measures After Skin Contact:  For brief contact with a small amount: Rewarm with body heat. Get immediate medical advice/attention. For extensive contact or a large amount: Immediately call a poison center/doctor and follow their advice. Specific treatment is urgent, incorrect first-aid practices will aggravate the injury. Protect affected area with a loose cover until proper medical treatment is received.

First-aid Measures After Eye Contact:  Rinse cautiously with water for at least 5 minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Obtain medical attention if irritation develops or persists.

First-aid Measures After Ingestion:  Rinse mouth. Do NOT induce vomiting. Obtain medical attention.

Symptoms/Injuries:  May cause frostbite on contact with the liquid. Asphyxia by lack of oxygen: risk of death.

Symptoms/Injuries After Inhalation:  In elevated concentrations may cause asphyxiation, central nervous system effects, and increased breathing rate. Symptoms of asphyxiation include headache, dizziness, rapid breathing, increased pulse, mood changes, tremors, cyanosis, muscular weakness, narcosis, numbness of the extremities, unconsciousness and death.

Symptoms/Injuries After Skin Contact:  Contact with gas/liquid escaping the container can cause frostbite and freeze burns.

Symptoms/Injuries After Eye Contact:  Contact with gas/liquid escaping the container can cause frostbite, freeze burns, and permanent eye damage.

Symptoms/Injuries After Ingestion:  Not considered a potential route of exposure, but contact with gas/liquid escaping the container can cause freeze burns and frostbite.

Chronic Symptoms:  None known.

Suitable Extinguishing Media:  Do not extinguish burning gas if flow cannot be shut off immediately. Extinguish secondary FIRES with appropriate materials. Use water spray to cool fire-exposed containers.

Unsuitable Extinguishing Media:  Do not use a heavy water stream. Use of heavy stream of water may spread fire.

Fire Hazard:  Extremely flammable gas.

Explosion Hazard:  May form flammable/explosive vapor-air mixture. Container may explode in heat of fire. When mixed with air and exposed to an ignition source, flammable vapors can burn in the open or explode in confined spaces. Being heavier than air, vapors may travel long distances to an ignition source and flash back. Runoff to sewer may cause fire or explosion hazard. Gas has low electroconductivity.  Flow may generate electrostatic charges resulting in risks of static discharge and possible ignition.

Reactivity:  Hazardous reactions will not occur under normal conditions. May react violently with halogens or halogenated compounds. May react violently with oxidants, causing fire and explosion hazard.

Precautionary Measures Fire:  Exercise caution when fighting any chemical fire.

Firefighting Instructions:  Leaking gas fire: Do not extinguish, unless leak can be stopped safely. Eliminate all ignition sources if safe to do so. Use water spray or fog for cooling exposed containers. Fight fire remotely due to the risk of explosion.

Protection During Firefighting:  Do not enter fire area without proper protective equipment, including respiratory protection.

Hazardous Combustion Products:  Carbon oxides (CO, CO₂).

Other Information:  Use water spray to disperse vapors.

General Measures:  Eliminate every possible source of ignition. Do not get in eyes, on skin, or on clothing. Do not breathe gas.

Protective Equipment:  Use appropriate personal protective equipment (PPE).

Emergency Procedures:  Evacuate unnecessary personnel.

Protective Equipment:  Equip cleanup crew with proper protection.

Emergency Procedures:  Evacuate unnecessary personnel, isolate, and ventilate area. Upon arrival at the scene, a first responder is expected to recognize the presence of dangerous goods, protect oneself and the public, secure the area, and call for the assistance of trained personnel as soon as conditions permit.

For Containment:  Stop leak, if possible without risk. As an immediate precautionary measure, isolate spill or leak area in all directions. Ventilate area.

Methods for Cleaning Up:  Clean up spills immediately and dispose of waste safely. Stop the source of the release, if safe to do so. Consider the use of water spray to disperse vapors. Isolate the area until gas has dispersed. Ventilate and gas test area before entering. Gas/vapour heavier than air. May accumulate in confined spaces, particularly at or below ground level. Use only non-sparking tools. Contact competent authorities after a spill.

Additional Hazards When Processed:  Asphyxiating gas at high concentrations. This product may contain light hydrocarbon material, which is associated with cardiac sensitization following very high exposures or with concurrent exposure to high stress levels or heart-stimulating substances like epinephrine and catecholamines. Careful consideration should be applied preceeding administration of epinehpherine or similar heart stimulating substances. Handle empty containers with care because residual vapors are flammable. As a result of flow, agitation, etc, electrostatic charges can be generated. Ruptured cylinders may rocket. Do not pressurize, cut, or weld containers.

Precautions for Safe Handling:  Handle as a flammable gas. Keep away from heat, sparks, and open flame! Electrical equipment should be approved for classified area. Bond and ground containers during product transfer to reduce the possibility of static-initiated fire or explosion. Wash hands and other exposed areas with mild soap and water before eating, drinking or smoking and when leaving work. Do not breathe gas. Do not get in eyes, on skin, or on clothing. Use appropriate personal protective equipment (PPE).

Hygiene Measures:  Handle in accordance with good industrial hygiene and safety procedures.

Technical Measures:  Comply with applicable regulations. Proper grounding procedures to avoid static electricity should be followed.

Storage Conditions:  Keep container closed when not in use. Store in a dry, cool and well-ventilated place. Keep in fireproof place. Keep/Store away from direct sunlight, extremely high or low temperatures and incompatible materials. Cylinders should be stored upright with valve protection cap in place and firmly secured to prevent falling.

Incompatible Materials:  Strong acids, strong bases, strong oxidizers. Halogens. Halogenated compounds. Chlorine. Nickel carbonyl. Oxygen.

Appropriate Engineering Controls

:

Suitable eye/body wash equipment should be available in the vicinity of any potential exposure. Ensure adequate ventilation, especially in confined areas. Use explosion-proof equipment. Proper grounding procedures to avoid static electricity should be followed. Gas detectors should be used when flammable gases or vapors may be released. Oxygen detectors should be used when asphixiating gases may be released. Have written confined space and tank entry procedures. Never allow tank entry without checking OXYGEN AND VAPOR levels. Use safety harness and safety line on person entering a tank. Stand-by person required with protective equipment available. Ensure all national/local regulations are observed.
