International Chemical Safety Cards STRYCHNINE ICSC: 0197 Strychnidin-10-one C21H22N2O2 Molecular mass: 334.4 ICSC #    0197 CAS #     57-24-9 RTECS # WL2275000 UN #        1692 EC #         614-003-00-5 April 12, 2000 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire. NO contact with oxidants. In case of fire in the surroundings: use appropriate extinguishing media. EXPLOSION EXPOSURE AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!  •INHALATION (See Ingestion). Local exhaust or breathing protection. Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.  •SKIN Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.  •EYES Safety goggles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Convulsions. Muscle stiffness. Shock or collapse. Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Refer for medical attention. Keep victim completely undisturbed. 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. Personal protection: self-contained breathing apparatus. Provision to contain effluent from fire extinguishing. Separated from strong oxidants, food and feedstuffs . Well closed. Do not transport with food and feedstuffs. Marine pollutant.

International Chemical Safety Cards STRYCHNINE ICSC: 0197 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: ODOURLESS AND COLOURLESS CRYSTALS, WITH BITTER TASTE. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating producing toxic fumes including nitrogen oxides . The substance is a weak base. Reacts with strong oxidants, causing fire and explosion hazard. OCCUPATIONAL EXPOSURE LIMITS: TLV: 0.15 mg/m³ as TWA; (ACGIH 2004). MAK: IIb (not established but data is available) (DFG 2004). OSHA PEL: TWA 0.15 mg/m3 NIOSH REL: TWA 0.15 mg/m3 NIOSH IDLH: 3 mg/m3 ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered. EFFECTS OF SHORT-TERM EXPOSURE: The substance may cause effects on the central nervous system , resulting in convulsions, muscle contractions, respiratory failure. Exposure may result in death. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Decomposes below boiling point Melting point: 275-285°C Density: 1.36 g/cm3 Solubility in water: none Octanol/water partition coefficient as log Pow: 1.68 ENVIRONMENTAL DATA The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment; special attention should be given to birds. This substance does enter the environment under normal use. Great care, however, should be given to avoid any additional release, e.g. through inappropriate disposal. N O T E S Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Card has been partly updated in April 2005.
