Hazards and Protection.
Dinitrophenol. Should be stored in a cool ventilated place away from area of acute fire hazard and away from powerful oxidizing agents. Dinitrophenol
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.
People exposed to the solid, or to a strong soln should wear protective clothing, hand protection, and, in confined spaces, the use of respiratory protective equipment.
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.
Dried-out material may explode if exposed to heat, flame, or shock.
Reacts as weak organic acids Incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides.
Fire Extinguishing Agents: Water, dry chemical, CO 2 , foam.
When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards.
Vapors are toxic.
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.
Remove from contaminated area. Administer oxygen and artificial respiration as needed.
Wash with soap and water.
Flush with water.
