International Chemical Safety Cards LEAD ACETATE ICSC: 0910 LEAD ACETATE Lead diacetate Lead dibasic acetate C4H6O4Pb / (CH3COO)2Pb Molecular mass: 325.3 CAS # 301-04-2 RTECS # AI5250000 ICSC # 0910 UN # 1616 EC # 082-007-00-9 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. In case of fire in the surroundings: all extinguishing agents allowed. EXPLOSION EXPOSURE PREVENT DISPERSION OF DUST! STRICT HYGIENE! AVOID EXPOSURE OF (PREGNANT) WOMEN! INHALATION Cough. Sore throat (see Ingestion). Local exhaust or breathing protection. Fresh air, rest. Refer for medical attention. SKIN Redness. Pain. Protective gloves. Remove contaminated clothes. Rinse skin with plenty of water or shower. EYES Redness. Pain. Safety goggles, 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. Constipation. Convulsions. Nausea. Vomiting. Do not eat, drink, or smoke during work. Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention. 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. Do NOT let this chemical enter the environment (extra personal protection: P2 filter respirator for harmful particles). Separated from bromates, carbonates, phosphates and phenols, food and feedstuffs. Well closed. Do not transport with food and feedstuffs.

International Chemical Safety Cards LEAD ACETATE ICSC: 0910 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS CRYSTALS OR WHITE POWDER. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating and on burning producing toxic and corrosive fumes including lead oxides, acetic acid. Reacts violently with bromates, phosphates, carbonates, phenols. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV (as Pb): ppm; 0.05 mg/m3 A3 (ACGIH 1996). MAK: ppm; 0.1 mg/m3; as Pb (1996). ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly when dispersed, especially, if powdered. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the eyes. The substance may cause effects on the blood and central nervous system , resulting in hemolytic anemia, nervous disorders, kidney impairment. The effects may be delayed. Medical observation is indicated. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The substance may have effects on the blood, bone marrow, cardiovascular system, kidneys, nervous system , resulting in anaemia, increase of blood pressure, paralysis, kidney impairment, behavioural effects. This substance is possibly carcinogenic to humans. Does cause serious reproductive toxicity in humans. PHYSICAL PROPERTIES Melting point: 280°C Relative density (water = 1): 3.3 Solubility in water, g/100 ml at 20°C: 44 ENVIRONMENTAL DATA The substance is toxic to aquatic organisms. This substance may be hazardous to the environment; special attention should be given to birds, mammals, soil, water. In the food chain important to humans, bioaccumulation takes place, specifically in plants and animals. It is strongly advised not to let the chemical enter into the environment because it persists in the environment. N O T E S Depending on the degree of exposure, periodic medical examination is indicated. The symptoms of acute intoxication do not become manifest until hours have passed.
