HAZARDS IDENTIFICATION


 Potential Health Effects


    Skin contact may cause skin irritation with discomfort or

    rash.  Prolonged skin contact may cause redness and

    inflammation of the hair follicles without skin

    sensitization.


    Eye contact may cause eye irritation with discomfort,

    tearing or blurring of vision.


    Inhalation of fluorine compounds released as decomposition

    products above 290 degC (554 degF) may cause lung irritation

    and pulmonary edema which require medical treatment.

    Inhalation of fumes or smoke from overheated or burning

    grease may cause polymer fume fever, a temporary flu-like

    illness accompanied by fever, chills, and sometimes cough,

    of approximately 24 hours duration.  Repeated episodes of

    polymer fume fever may cause lung damage.


 Carcinogenicity Information


 None of the components present in this material at concentrations

 equal to or greater than 0.1% are listed by IARC, NTP, OSHA or ACGIH

 as a carcinogen.



FIRST AID MEASURES


 First Aid


    INHALATION


    If inhaled, remove to fresh air.  If not breathing, give

    artificial respiration.  If breathing is difficult, give oxygen.

    Call a physician.


    SKIN CONTACT


    Flush skin with water after contact.  Wash contaminated clothing

    before reuse.


    EYE CONTACT


    In case of contact, immediately flush eyes with plenty of water

    for at least 15 minutes.  Call a physician.


    INGESTION


    If swallowed, do not induce vomiting.  Immediately give 2 glasses

    of water.  Never give anything by mouth to an unconscious person.

    Call a physician.


 Notes to Physicians


    Activated charcoal mixture may be administered.  To prepare

    activated charcoal mixture, suspend 50 grams activated charcoal in

    400 mL water and mix thoroughly.  Administer 5 mL/kg, or 350 mL

    for an average adult.



FIRE FIGHTING MEASURES


 Flammable Properties


    Flash Point             : None

    Method                  : TCC


    Non-combustible.


 Extinguishing Media


    Use media appropriate for surrounding material.


 Fire Fighting Instructions


    Wear self-contained breathing apparatus.  Wear full protective

    equipment.


    Decomposition at flame temperatures may form toxic fluorine

    compounds. Avoid breathing decomposition products.



ACCIDENTAL RELEASE MEASURES


 Safeguards (Personnel)


    NOTE: Review FIRE FIGHTING MEASURES and HANDLING (PERSONNEL)

    sections before proceeding with clean-up.  Use appropriate

    PERSONAL PROTECTIVE EQUIPMENT during clean-up.


 Accidental Release Measures


    Place in container for disposal.  Remove source of heat

    and flame.



HANDLING AND STORAGE


 Handling (Personnel)


    Avoid contact with eyes.  Avoid contact with skin.  Wash

    thoroughly after handling.  Do not store or consume food, drink or

    tobacco in areas where they may become contaminated with this

    material.


 Storage


    Keep container tightly closed.  Do not store or consume food,

    drink or tobacco in areas where they may become contaminated with

    this material.


    Keep away from heat and flames to avoid decomposition

    products.



EXPOSURE CONTROLS/PERSONAL PROTECTION


 Engineering Controls


    Keep container tightly closed.


    Keep away from heat and flames.


 Personal Protective Equipment


    EYE/FACE PROTECTION


    Wear safety glasses or coverall chemical splash goggles.


    RESPIRATORS


    Wear NIOSH approved respiratory protection, as appropriate.


    PROTECTIVE CLOTHING


    Where there is potential for skin contact have available and wear

    as appropriate impervious gloves, apron, pants, and jacket.


 Exposure Guidelines


  Exposure Limits

    "Krytox" 1500XP Series Fluorinated Oils

    PEL   (OSHA)             : None Established

    TLV   (ACGIH)            : None Established



PHYSICAL AND CHEMICAL PROPERTIES


 Physical Data


    pH                      : Neutral

    Odor                    : Odorless

    Form                    : Oil

    Color                   : Clear

    Specific Gravity        : 1.9



STABILITY AND REACTIVITY


 Chemical Stability


    Stable at normal temperatures and storage conditions.


 Incompatibility with Other Materials


    None reasonably foreseeable.


 Decomposition


    Heating above 260-290 degC (500-554 degF) may form

    potentially toxic fluorine compounds.  Depolymerization may

    occur in the presence of some metal oxides at temperatures

    above 288 degC (550 degF).  Decomposition occurs at

    increasing rates as temperature is raised above 355 degC

    (670 degF).


 Polymerization


    Polymerization will not occur.



TOXICOLOGICAL INFORMATION


 Animal Data


      Perfluoroalkylether:


        Inhalation 4 hour ALC:  >19.54 mg/L in rats

        Skin Absorption ALD:    >17,000 mg/kg in rabbits

        Oral ALD:               >25,000 mg/kg in rats


    Perfluoroalkylether is a mild eye irritant, is not tested

    for skin irritation, and is not tested for animal

    sensitization.  A single inhalation exposure to

    perfluoroalkylether caused nonspecific effects such as

    respiratory irritation.  Exposure to thermal decomposition

    products produced irritation, irregular respiration,

    tremors, and increased liver weight.  No animal test reports

    are available to define carcinogenic, mutagenic,

    developmental, or reproductive hazards.



DISPOSAL CONSIDERATIONS


 Waste Disposal


    Treatment, storage, transportation, and disposal must be in

    accordance with applicable Federal, State/Provincial, and Local

    regulations.  Do not flush to surface water or sanitary sewer

    system.
