Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Powder, water spray, foam, carbon dioxide. EXPLOSION Above 96°C explosive vapour/air mixtures may be formed. Above 96°C use a closed system, ventilation.   EXPOSURE PREVENT GENERATION OF MISTS! INHALATION Abdominal pain. Dizziness. Headache. Laboured breathing. Nausea. Metallic taste. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Artificial respiration if indicated. SKIN MAY BE ABSORBED! Redness. Pain. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap. EYES Redness. Safety spectacles, 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 (Further see Inhalation). Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer (extra personal protection: complete protective clothing including self-contained breathing apparatus). Separated from food and feedstuffs. Unbreakable packaging; put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs.

International Chemical Safety Cards METHYLCYCLOPENTADIENYL MANGANESE TRICARBONYL ICSC: 1169 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: DARK ORANGE LIQUID. PHYSICAL DANGERS: CHEMICAL DANGERS: On combustion, forms toxic or irritating fumes including manganese oxides and carbon monoxide. The substance decomposes under influence of light. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV (as Mn): ppm; 0.2 mg/m3 (skin) (ACGIH 1994-1995). ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation, through the skin and by ingestion. INHALATION RISK: A harmful contamination of the air can be reached rather quickly 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 central nervous system , resulting in tissue lesions. Medical observation is indicated. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: 231.7°C Relative density (water = 1): 1.39 Solubility in water: none Flash point: 96°C c.c.

ENVIRONMENTAL DATA	The substance is toxic to aquatic organisms.
N O T E S
Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken. Do NOT take working clothes home. CI-2, AK-33X and Antiknock 33 are trade names. Transport Emergency Card: TEC (R)-61G04A
