Hazards and Protection.
Storage
It is unstable in alkalies and concentrated acids, and is slowly decomposed by ultraviolet light. Suffers slight hydrolysis on long contact with water.
Handling
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.
Protection
Protective gloves and Clothing. Safety goggles or face shield.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
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.
Stability
Unstable in alkali and concentrated acids, suffers slight hydrolysis on long contact with water and is slowly decomposed by UV light.

Fire.
Fire fighting
Small Fires: Dry chemical, carbon dioxide or water spray. Large Fires: Dry chemical, carbon dioxide, alcohol-resistant foam or water spray.
Fire potential
Burns at temperature above 150 C.
Hazards
When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards.
Combustion products
Fire may produce irritating, corrosive and/or toxic gases.

Health.
Exposure effects
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.
   Ingestion
Nausea, vomiting, and abdominal pain may be prominent.
   Inhalation
Dyspnea, tachypnea, cyanosis, and pulmonary edema may occur.
   Skin
Yellow staining of skin occurs following contact with nitrophenols. Diaphoresis is common.
   Eyes
Cataracts, secondary glaucoma, symblepharon, paresis of accomodation, and nystagmus have been reported.

First aid
 
   Ingestion
Seek medical assistance.
   Inhalation
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.
   Skin
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.
   Eyes
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.
