[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. Extinguishing media: Use agent most appropriate to extinguish fire. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
[Fire Potential]

This chemical is combustible.
[Ingestion]

Never give anything by mouth to an unconscious person. Get medical aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
[Inhalation]

Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. DO NOT use mouth-to-mouth respiration.
[Skin]

Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
[Eyes]

Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
[Storage]

Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.
[Handling]

Wash thoroughly after handling. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation.
[Inhalation]

May cause respiratory tract irritation. The toxicological properties of this substance have not been fully investigated.
[Skin]

May cause skin irritation.
[Eyes]

May cause eye irritation.
[Ingestion]

May cause irritation of the digestive tract. The toxicological properties of this substance have not been fully investigated.
[Hazards]

[Personal Protection]

Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
[Respirators]

A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.
[Exposure Effects]

Rapid heart rate, rapid breathing, abnormally low blood pressure, and respiratory depression may occur. Headache, dizziness, lethargy, and coma are possible. Nitrobenzene is a possible animal teratogen.
[Appearance]

Light yellow needles or amber crystalline solid.
