Brandgefahren	Flash point data for this chemical are not availablehowever, it is probably combustible. (NTP, 1992)Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Finely dispersed particles form explosive mixtures in air.
Gesundheitsgefahren	SYMPTOMS: Symptoms of exposure to this compound include irritation of the skin, eyes, mucous membranes and upper respiratory tract, and narcosis. Other symptoms include eczemoid contact dermatitis and bronchial asthma. It can cause hypersensitivity reactions (skin sensitization), skin allergies (such as disseminated neurodermatitis), arthritis, conjunctivitis, gastrointestinal disturbances, neurological symptoms, spleen enlargement, vertigo, gastritis, diplopia, asthenia, exfoliative dermatitis and, on chronic exposure, jaundice and liver atrophy. Eye contact can cause inflammation, damage of the periocular and ocular tissues, edema and hyperemia of the lids and conjunctiva with tearing and exophthalmos, pain and burning of the eyes, redness and swelling of the lids, erosion of the corneal epithelium, iritis, iridocyclitis and retrobulbar neuritis with central scotoma. There have been cases of limitation of eye movement with proptosis, involvement of the cornea with loss of epithelium and infiltration, optic neuritis with papilledema, and lost or permanently impaired vision due to severe corneal ulceration.
