Safety & Transport Information
Cerium resembles aluminum in its pharmacological action as well as in its chemical properties. The insoluble salts such as the oxalates are stated to be nontoxic even in large doses. It is used to prevent vomiting in pregnancy. The average dose is from 0.05 to 0.5 g.The effect on the central nervous system of the rare-earth metals following inhalation may preclude welding operations with these materials to any large extent. Cerium is stated to produce polycythemia but is useless in the treatment of anemia owing to its toxic effects. The salts of cerium increase the blood coagulation rate. See also RARE EARTHS. A strong reducing agent. Moderate fire hazard; ignites spontaneously in air at 150–180°. Moderate explosion hazard in the form of dust when exposed to flame. The metal or its alloys spark with friction. Many alloys are pyrophoric in air. See also IRON DUST. Explosive reaction with zinc. Very exothermic reaction with antimony or bismuth. Ignites when heated in atmospheres of CO2 + N2, Cl2, or Br2. Violent reaction when heated with phosphorus (400°C), silicon (1400°C).
Risk Codes:
R11 - Highly flammable R14/15 - Reacts violently with water, liberating extremely flammable gases R15 - Contact with water liberates extremely flammable gases R20/21/22 - Harmful by inhalation, in contact with skin and if swallowed R22 - Harmful if swallowed R23 - Toxic by inhalation R36/37/38 - Irritating to eyes, respiratory system and skin R36/38 - Irritating to eyes and skin
Safety Codes:
S16 - Keep away from sources of ignition - No smoking S26 - In case of contact with eyes, rinse immediately with plenty of water and seek medical advice S36 - Wear suitable protective clothing S36/37/39 - Wear suitable protective clothing, gloves and eye/face protection S43 - In case of fire use ... (indicate in the space the precise type of fire-fighting equipment. If water increases the risk add - Never use water)
