    4.First-aid measures

    4.1 Description of necessary first-aid measures

    General advice

    Consult a physician. Show this safety data sheet to the doctor in attendance.

    If inhaled

    Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.

    In case of skin contact

    ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention .

    In case of eye contact

    First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

    If swallowed

    Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.

    4.2 Most important symptoms/effects, acute and delayed

    Excerpt from ERG Guide 121 [Gases - Inert]: Vapors may cause dizziness or asphyxiation without warning. Vapors from liquefied gas are initially heavier than air and spread along ground. (ERG, 2016)

    Inhalation can cause asphyxiation, if atmosphere does not contain oxygen; dizziness, unconsciousness, or even death can result. Contact of liquid with skin or eyes causes frostbite burns. (USCG, 1999)

    4.3 Indication of immediate medical attention and special treatment needed, if necessary

    Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Simple asphyxiants and related compounds/

    5.Fire-fighting measures

    5.1 Extinguishing media

    Suitable extinguishing media

    If material involved in fire: Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Cool all affected containers with flooding quantiites of water. Apply water from as far a distance as possible. /Nitrogen, compressed/

    5.2 Specific hazards arising from the chemical

    Excerpt from ERG Guide 121 [Gases - Inert]: Non-flammable gases. Containers may explode when heated. Ruptured cylinders may rocket. (ERG, 2016)

    Behavior in Fire: Containers may explode when heated. (USCG, 1999)

    5.3 Special protective actions for fire-fighters

    Wear self-contained breathing apparatus for firefighting if necessary.

    6.Accidental release measures

    6.1 Personal precautions, protective equipment and emergency procedures

    Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.

    6.2 Environmental precautions

    7.Handling and storage

    7.1 Precautions for safe handling

    Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2.

    7.2 Conditions for safe storage, including any incompatibilities

    Fireproof if in building. Cool. Keep in a well-ventilated room.Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage.
