Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire. In case of fire in the surroundings: all extinguishing agents allowed. EXPLOSION EXPOSURE STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN! IN ALL CASES CONSULT A DOCTOR! INHALATION Pupillary constriction, muscle cramp, excessive salivation. Sweating. Nausea. Vomiting. Dizziness. Convulsions. Unconsciousness. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Refer for medical attention. SKIN MAY BE ABSORBED! Redness. Pain (further see Inhalation). Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention. EYES Redness. Pain. Blurred vision. Face shield, 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 Abdominal cramps. Vomiting Diarrhoea. (see inhalation). Do not eat, drink, or smoke during work. Wash hands before eating. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Rest. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. Chemical protection suit including self-contained breating apparatus.

International Chemical Safety Cards NALED ICSC: 0925 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: YELLOW LIQUID OR WHITE CRYSTALS , WITH PUNGENT ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating, on contact with acids, bases, producing toxic and corrosive fumes including hydrogen chloride, hydrogen bromide, phosphorous oxides. Reacts with water. Attacks metal, plastic, rubber and coatings. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV: ppm; 3 mg/m3 A4 (skin) (ACGIH 1996). OSHA PEL: TWA 3 mg/m3 NIOSH REL: TWA 3 mg/m3 skin NIOSH IDLH: 200 mg/m3 ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion. INHALATION RISK: A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the nervous system , resulting in convulsions, respiratory failure. Cholinesterase inhibitor. Exposure may result in death. The effects may be delayed. Medical observation is indicated. PHYSICAL PROPERTIES Boiling point at 0.066 kPa: 110°C Melting point: 26.5-27.5°C Relative density (water = 1): 1.96 at 25°C Density: 1.96 at 25°C Solubility in water: none Vapour pressure, Pa at 20°C: 0.26 Octanol/water partition coefficient as log Pow: 1.38 ENVIRONMENTAL DATA This substance may be hazardous to the environment; special attention should be given to water organisms. Avoid release to the environment in circumstances different to normal use. NOTES 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. Carrier solvents used in commercial formulations may change physical and toxicological properties. Bromex, Dibrom and Orthodibrom are trade names.
