1,4-DICHLORO-2-NITROBENZENE ICSC: 1618 2,5-Dichloronitrobenzene 1-Nitro-2,5-dichlorobenzene Nitro-p-dichlorobenzene C6H3Cl2NO2/ Cl2C6H3NO2 Molecular mass: 192.00 ICSC #    1618 CAS #     89-61-2 RTECS # CZ5260000 UN #        1578 Types of Hazard/ Exposure Acute Hazards/ Symptoms Prevention First Aid/ Fire Fighting FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Water spray, dry powder, foam, carbon dioxide. Explosion Exposure PREVENT DISPERSION OF DUST!  •Inhalation Ventilation (not if powder), local exhaust, or breathing protection. Fresh air, rest.  •Skin Protective gloves. Rinse and then wash skin with water and soap.  •Eyes Redness. Safety spectacles Rinse with plenty of water (remove contact lenses if easily possible).  •Ingestion Do not eat, drink, or smoke during work. Rinse mouth. Give one or two glasses of water to drink. Spillage Disposal Storage Packaging & Labelling Personal protection: particulate filter adapted to the airborne concentration of the substance. Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment. Separated from bases, strong oxidants and food and feedstuffs. Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing. Do not transport with food and feedstuffs. UN Hazard Class: 6.1 UN Packing Group: II Signal: Warning Excl mark Harmful if swallowed Toxic to aquatic life 1,4-DICHLORO-2-NITROBENZENE ICSC: 1618 Important Data Physical State; Appearance: YELLOW FLAKES Physical Dangers: Chemical Dangers: The substance decomposes on heating producing toxic and corrosive fumes including hydrogen chloride and nitrogen oxides. Reacts with strong oxidants and bases Occupational Exposure Limits: TLV not established. MAK not established. Routes of Exposure: The substance can be absorbed into the body by ingestion and through the skin. Inhalation Risk: A nuisance-causing concentration of airborne particles can be reached quickly when dispersed, especially if powdered.
