First aid
Skin Contact: Flood all areas of body thathave contacted the substance with water. Do not wait toremove contaminated clothing; do it under the water stream.Use soap to help assure removal. Isolate contaminatedclothing when removed to prevent contact by others. EyeContact: Remove any contact lenses at once. Immediatelyflush eyes well with copious quantities of water or normalsaline for at least 2030 min. Seek medical attention.Inhalation: Leave contaminated area immediately; breathefresh air. Proper respiratory protection must be supplied toany rescuers. If coughing, difficult breathing or any othersymptoms develop, seek medical attention at once, even ifsymptoms develop many hours after exposure. Ingestion: Ifunconscious or convulsing, do not induce vomiting or giveanything by mouth. Assure that victim’s airway is open andlay him on his side with his head lower than his body andtransport at once to a medical facility. If conscious and notconvulsing, give a glass of water to dilute the substance. Ifmedical advice is not readily available, do not inducevomiting, and rush the victim to the nearest medicalfacility.
storage
(1) Color Code—Yellow: Reactive Hazard; Storein a location separate from other materials, especially flammables and combustibles. (2) Color Code—Blue (all isomers): Health Hazard/Poison: Store in a secure poisonlocation. Prior to working with dinitronaphthalenes youshould be trained on its proper handling and storage. Storein tightly closed containers in a refrigerator or cool, wellventilated area away from alkalies, aluminum, sulfur,sulfuric acid, and heat. A regulated, marked area should beestablished where this chemical is handled, used, or storedin compliance with OSHA Standard 1910.1045.
Shipping
Nitronaphthalene is not specifically cited inDOT’s Performance-Oriented Packaging Standards. But itmay be considered “Toxic solids, organic, n.o.s.” This compound requires a shipping label of “POISONOUS/TOXICMATERIALS.” It may fall into DOT Hazard Class 6.1 andPacking Group III. Dyes, solid, toxic, n.o.s. [or] Dye intermediates, solid, toxic,
Incompatibilities
The 1,3- and 1,8-isomers are strong oxidizers. All are potentially explosive materials. These materials may form explosive metal salts with alkalies. Violentreaction with aluminum, sulfur, and sulfuric acid in thepresence of heat.
