Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Powder, water spray, foam, carbon dioxide. EXPLOSION EXPOSURE PREVENT DISPERSION OF DUST!  •INHALATION Blue lips or finger nails. Blue skin. Dizziness. Headache. Confusion. Convulsions. Nausea. Unconsciousness. Local exhaust or breathing protection. Fresh air, rest. Refer for medical attention.  •SKIN Protective gloves. Remove contaminated clothes. Rinse skin with plenty of water or shower.  •EYES Safety goggles or eye protection in combination with breathing protection. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION (See Inhalation). Do not eat, drink, or smoke during work. Rinse mouth. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment. (Extra personal protection: self-contained breathing apparatus). Separated from strong oxidants, strong bases. Cool. Dry.

International Chemical Safety Cards 4-NITRO-N-PHENYLBENZENAMINE ICSC: 0804 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: YELLOW NEEDLES. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating or on burning producing toxic fumes (nitrogen oxides). Reacts with strong oxidants. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. EFFECTS OF SHORT-TERM EXPOSURE: The substance may cause effects on the blood , resulting in formation of methaemoglobin. Medical observation is indicated. The effects may be delayed. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: 343°C Melting point: 132-135°C Solubility in water: none Vapour pressure, Pa at 25°C: negligible Flash point: 190°C o.c. Octanol/water partition coefficient as log Pow: 3.82 ENVIRONMENTAL DATA The substance is very toxic to aquatic organisms. It is strongly advised not to let the chemical enter into the environment. The substance may cause long-term effects in the aquatic environment. N O T E S Depending on the degree of exposure, periodic medical examination is indicated. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
