International Chemical Safety Cards TETRAETHYL LEAD ICSC: 0008 TETRAETHYL LEAD Tetraethyl plumbane Lead tetraethyl TEL Pb(C2H5)4 Molecular mass: 323.45 CAS # 78-00-2 RTECS # TP4550000 ICSC # 0008 UN # 1649 EC # 082-002-00-1 TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Combustible. NO open flames. Powder, water spray, foam, carbon dioxide. EXPLOSION Above 77°C explosive vapour/air mixtures may be formed. Above 77°C closed system, ventilation, and explosion-proof electrical equipment. In case of fire: keep drums, etc., cool by spraying with water. Combat fire out of sheltered position. EXPOSURE PREVENT GENERATION OF MISTS! STRICT HYGIENE! AVOID EXPOSURE OF (PREGNANT) WOMEN! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN! IN ALL CASES CONSULT A DOCTOR! INHALATION Convulsions. Dizziness. Headache. Unconsciousness. Vomiting. Weakness. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Artificial respiration if indicated. Refer for medical attention. SKIN MAY BE ABSORBED! Redness. (further see Inhalation). Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention. EYES 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 Convulsions. Diarrhoea. Dizziness. Headache. Unconsciousness. Vomiting. Weakness. Do not eat, drink, or smoke during work. Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give plenty of water to drink. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Evacuate danger area! Consult an expert! Ventilation. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. (extra personal protection: complete protective clothing including self-contained breathing apparatus). Fireproof. Separated from strong oxidants, acids. Keep in the dark. Ventilation along the floor. Unbreakable packaging; put breakable packaging into closed unbreakable container.

International Chemical Safety Cards TETRAETHYL LEAD ICSC: 0008 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS VISCOUS LIQUID , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: The vapour is heavier than air CHEMICAL DANGERS: The substance decomposes on heating above 110°C and under influence of light producing toxic fumes: carbon monoxide, lead. Reacts violently with strong oxidants, acids, halogens, oils and fats causing fire and explosion hazard. Attacks rubber and some plastics and coatings. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV (as Pb): ppm; 0.1 mg/m3 (skin) (ACGIH 1991-1992) PDK (as Pb): 0.005 mg/m3 P (USSR 1987) OSHA PEL: TWA 0.075 mg/m3 skin NIOSH REL: TWA 0.075 mg/m3 skin NIOSH IDLH: 40 mg/m3 (as Pb) ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation, through the skin, 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, the respiratory tract. The substance may cause effects on the central nervous system , resulting in irritability, insomnia, cardiac disorders. Exposure could cause lowering of consciousness. Exposure to high level may result in death. Medical observation is indicated. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: May cause reproductive toxicity in humans. PHYSICAL PROPERTIES Boiling point (decomposes): 200°C Melting point: -136.8°C Relative density (water = 1): 1.7 Solubility in water: None Vapour pressure, kPa at 20°C: 0.027 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.00 Flash point: 77°C Auto-ignition temperature: Above 110°C Explosive limits, vol% in air: 1.8 ENVIRONMENTAL DATA It is strongly advised not to let the chemical enter into the environment. NOTES Depending on the degree of exposure, periodic medical examination is indicated. The relation between odour and the occupational exposure limit cannot be indicated. Do NOT take working clothes home. Tetraethyl lead used as an anti-knock compound in gasoline also contains ethylene dibromide and ethylene dichloride as impurities. Also consult ICSC #0052.
