Hazards and Protection.
Storage
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
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
Wear full protective clothing and self-contained breathing apparatus.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Keep spilled material wet. Do not attempt to sweep up dry material.
Stability
Extreme - explodes at 423 C or with shock. Reactive at high temperature or pressure.
Incompatibilities
Reacts vigorously with reducing materials. Violent reaction with aluminum; BP; cyanide; esters; PN2H; phosphorus; sodium cyanide; tinchloride; sodium hypophosphite; thiocyanates, nitrates
Decomposition
When heated to decomposition it emits highly toxic fumes of oxides of nitrogen.

Fire.
Fire fighting
Dangerously explosive. Flood with water. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.
Fire potential
Moderate by spontaneous chemical reaction.
Hazards
DRIED OUT material may explode if exposed to heat, flame, friction orshock; Treat as an explosive.
Combustion products
Contain highly toxic NOx fumes.

Health.
Poison_Class
3
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. 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.
