Hazards and Protection.
Keep tightly closed. Store in a cool dry place.
Compatible chemical-resistant gloves. Chemical safety goggles. Protective clothing.
Sweep up, place in a bag and hold for waste disposal. Avoid raising dust. Ventilate area and wash spill site after material pickup is complete.
Stable at normal temperatures and pressures.
Strong oxidizing agents.
Oxides of carbon.
Extinguish with water spray, carbon dioxide, dry chemical powder or appropriate foam. Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes.
Emits toxic fumes under fire conditions.
May be harmful by inhalation, ingestion, or skin absorption. May cause irritation. Causes spasms of the extremities, usually triggered by exertion similar to the clinical symptoms in myotonia congenita (Thomsens disease). The typical myotonic symptoms were produced in mice by intraperitoneal injection of the acid in 0.25% methylcellulose solution and consisted of a temporary rigid extension of the hind leg when the animal is disturbed. At higher doses, these extensor spasms may occur continuously. See R.B. Moffett and A.H. Tang, J. Med. Chem., 1968, 11, 1020.
If swallowed, wash out mouth with water provided person is conscious. Call a physician.
If inhaled, remove to fresh air. If not breathing give artificial respiration. If breathing is difficult, give oxygen.
In case of contact, immediately wash skin with soap and copious amounts of water. Remove contaminated clothing and shoes. Call a physician.
In case of contact with eyes, flush with copious amounts of water for at least 15 minutes. Assure adequate flushing by separating the eyelids with fingers. Call a physician.
