Ventilation, local exhaust, or breathing protection. Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.  •SKIN MAY BE ABSORBED! Redness. Blue lips or fingernails. Blue skin. (Further see Inhalation). Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.  •EYES Redness. Safety goggles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Blue lips or fingernails. Blue skin. Dizziness. Headache. Laboured breathing. Do not eat, drink, or smoke during work. Rinse mouth. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Consult an expert! Ventilation. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. (Extra personal protection: A/P2 filter respirator for organic vapour and harmful dust). Separated from strong oxidants, strong bases. Cool. Dry. Well closed.

International Chemical Safety Cards 1,3-DICHLORO-5-NITROBENZENE ICSC: 0255 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: CRYSTALS. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating producing toxic fumes including nitrogen oxides, hydrogen chloride (see ICSC 0163). Reacts with strong bases and strong oxidants . OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation, through the skin and by ingestion. INHALATION RISK: No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the blood system , resulting in formation of methaemoglobin. The effects may be delayed. Medical observation is indicated. See Notes. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Melting point: 64.5°C Relative density (water = 1): 1.692 Solubility in water: none Vapour pressure, kPa at 20°C: see Notes Relative vapour density (air = 1): 6.6 Relative density of the vapour/air-mixture at 20°C (air = 1): see Notes Flash point: see Notes Auto-ignition temperature: see Notes Explosive limits, vol% in air: see Notes ENVIRONMENTAL DATA N O T E S The vapour pressure, relative density of the vapour/air mixture and auto-ignition temperature are unknown in literature. The substance is combustible but no flash point is available in literature. Explosive limits are unknown in literature. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
