    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

    Remove contaminated clothes. Rinse skin with plenty of water or shower.

    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

    Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention .

    4.2 Most important symptoms/effects, acute and delayed

    Inhalation of vapor is not hazardous. Ingestion causes stupor or coma, sometimes leading to fatal kidney injury. (USCG, 1999)

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

    /SRP:/ 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. /Ethylene glycol, glycols, and related compounds/

    no data available

    10.2 Chemical stability

    Polyethylene glycols are chemically stable in air and in solution, although grades with a mol wt < 2000 are hygroscopic. Polyethylene glycols do not support microbial growth, and they do not become rancid. Polyethylene glycols and aqueous polyethylene glycol solutions can be sterilized by autoclaving, filtration, or gamma irradiation ... Ideally, sterilization should be carried out in an inert atmosphere.

    10.3 Possibility of hazardous reactions
