    of protective equipment must be selected according to the concentration and amount of the
    dangerous substance at the specific workplace.
  Respiratory protection
    Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator
    with multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backup
    to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air
    respirator. Use respirators and components tested and approved under appropriate government
    standards such as NIOSH (US) or CEN (EU).
  Control of environmental exposure
    Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into
    the environment must be avoided.

  Additional Information
    RTECS: CY1400000
    Nausea, Dizziness, Headache, narcosis, Inhalation of high concentrations of benzene may have an initial
    stimulatory effect on the central nervous system characterized by exhilaration, nervous excitation and/or
    giddiness, depression, drowsiness, or fatigue. The victim may experience tightness in the chest,
    breathlessness, and loss of consciousness. Tremors, convulsions, and death due to respiratory paralysis
    or circulatory collapse can occur in a few minutes to several hours following severe exposures. Aspiration
    of small amounts of liquid immediately causes pulmonary edema and hemorrhage of pulmonary tissue.
    Direct skin contact may cause erythema. Repeated or prolonged skin contact may result in drying, scaling
    dermatitis, or development of secondary skin infections. The chief target organ is the hematopoietic
    system. Bleeding from the nose, gums, or mucous membranes and the development of purpuric spots,
    pancytopenia, leukopenia, thrombocytopenia, aplastic anemia, and leukemia may occur as the condition
    progresses. The bone marrow may appear normal, aplastic or hyperplastic, and may not correlate with
    peripheral blood-forming tissues. The onset of effects of prolonged benzene exposure may be delayed for
    many months or years after the actual exposure has ceased., Blood disorders
