Hazards and Protection.
It is unstable in alkalies and concentrated acids, and is slowly decomposed by ultraviolet light. Suffers slight hydrolysis on long contact with water.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Protective gloves and Clothing. Safety goggles or face shield.
Wear positive pressure self-contained breathing apparatus (SCBA).
ELIMINATE all ignition sources. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS.
Unstable in alkali and concentrated acids, suffers slight hydrolysis on long contact with water and is slowly decomposed by UV light.
Small Fires: Dry chemical, carbon dioxide or water spray. Large Fires: Dry chemical, carbon dioxide, alcohol-resistant foam or water spray.
Burns at temperature above 150 C.
When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards.
Fire may produce irritating, corrosive and/or toxic gases.
Blood pressure, pulse, respiratory rate, and temperature may all be elevated after exposure. In severe poisoning, restlessness, seizures, and coma may occur. Animal studies show developmental malformations involving the neurologic, ophthalmic, urologic, and skeletal systems of offsprings.
Nausea, vomiting, and abdominal pain may be prominent.
Dyspnea, tachypnea, cyanosis, and pulmonary edema may occur.
Yellow staining of skin occurs following contact with nitrophenols. Diaphoresis is common.
Cataracts, secondary glaucoma, symblepharon, paresis of accomodation, and nystagmus have been reported.
Seek medical assistance.
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult.
Wash affected areas of skin and hair vigorously with soap and water. Dermal exposure is usually accompanied by a yellowish discoloration which does not have to be removed completely to prevent absorption.
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
