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
Gloves and respirator filter.
Respirators
Use NIOSH/MSHA approved respirator appropriate for exposure of concern.
Small spills/leaks
Evacuate area and ventilate. Wear protective equipment. If required, use an inert absrobent. Sweep up and place in an appropriate container for disposal. Wash contaminated surfaces.
Stability
No data.
Incompatibilities
Strong oxidizing agents.

Fire.
Flash Point,°C
163
Fire fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use agent most appropriate to extinguish fire.

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 attention. If individual is drowsy or unconscious, do not give anything by mouth; place individual on the left side with the head down. Contact a physician, medical facility, or poison control center for advice about whether to induce vomiting. If possible, do not leave individual unattended.
   Inhalation
If symptoms develop, move individual away from exposure and into fresh air. If symptoms persist, seek medical attention. If breathing is difficult, administer oxygen. Keep person warm and quiet; seek immediate medical attention.
   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.
