    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

    If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician.

    In case of skin contact

    Wash off with soap and plenty of water. Consult a physician.

    In case of eye contact

    Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician.

    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

    CALL FOR MEDICAL AID. LIQUID: Irritating to skin, eyes, and respiratory tract. Remove contaminated clothing and shoes. Flush affected areas with plenty of water. IF IN EYES, hold eyelids open and flush with plenty of water. VAPORS: Irritating to skin, eyes and respiratory tract. Move to fresh air. If breathing has stopped, give artificial respiration. If breathing is difficult, give oxygen. IF IN EYES, hold eyelids open and flush with plenty of water. Harmful if inhaled or swallowed. Vapor or mist is irritating to the eyes, mucous membranes, and upper respiratory tract. Prolonged contact can cause dermititis, and prolonged exposure can cause nausea, dizziness and headache. (USCG, 1999)

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

    no data available

    5.Fire-fighting measures

    5.1 Extinguishing media

    Suitable extinguishing media

    Excerpt from ERG Guide 128 [Flammable Liquids (Water-Immiscible)]: CAUTION: All these products have a very low flash point: Use of water spray when fighting fire may be inefficient. CAUTION: For mixtures containing alcohol or polar solvent, alcohol-resistant foam may be more effective. SMALL FIRE: Dry chemical, CO2, water spray or regular foam. LARGE FIRE: Water spray, fog or regular foam. Do not use straight streams. Move containers from fire area if you can do it without risk. FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn. (ERG, 2016)

    5.2 Specific hazards arising from the chemical

    Combustible. (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

    Pick up and arrange disposal. Sweep up and shovel. Keep in suitable, closed containers for disposal.

    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

    Store in cool place. Keep container tightly closed in a dry and well-ventilated place.
