Lead stearate is an organic lead compound. It is a white powder with a slight fatty odor.

It is used as a stabilizer for plastics and rubber processing; in extreme-pressure lubricants and as a drier in varnishes

Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.

UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required

Dust may form explosive mixture with air; keep away from high heat and sources of ignition. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, and epoxides

Lead stearate is an organic lead compound. Itis a white powder with a slight fatty odor. Molecularweight = 1734.87; Freezing/Melting point = 116℃; Flashpoint = 232℃. Hazard Identification (based on NFPA-704M Rating System): Health 2, Flammability 1, Reactivity 0.Insoluble in water.

Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with thischemical you should be trained on its proper handling andstorage. Store in tightly closed containers in a cool, wellventilated area away from heat, oxidizers, strong acids.Dust may explode at high temperature. Lead is regulated byan OSHA Standard 1910.1025. All requirements of the standard must be followed.

Ingestion of large amounts of leadmay lead to seizures, coma, and death. The effects of exposure to fumes and dusts of inorganic lead may notdevelop quickly. Symptoms may include decreased physicalfitness, fatigue, sleep disturbance, headache, aching bonesand muscles, constipation, abdominal pains, and decreasedappetite. These effects are reported to be reversible if exposure ceases. Inhalation of large amounts of lead may lead toseizures, coma, and death. Between 1 oz and 1 lb of leadstearate may be fatal.Note: Lead is a cumulative poison. Increasing amounts canbuild up in the body, eventually reaching a point wheresymptoms and disability occur. Lead dust carried home oncontaminated clothing can result in exposure and symptomsin other family members. Standards only protect for inhalation exposure. Extra precautions should be taken if skinexposure also occurs.

While lead stearate has not beenidentified as a teratogen, or a reproductive hazard, lead andcertain lead compounds have been determined to be teratogens and may also cause reproductive damage such asreduced fertility and interfere with menstrual cycles. Handlewith extreme caution. Lead can accumulate in the bodyover a period of time. Therefore, long-term exposures tolower levels can result in a buildup of lead in the body andmore severe symptoms. These may include anemia, paleskin, a blue line at the gum margin, decreased handgripstrength, abdominal pain, severe constipation, nausea,vomiting, and paralysis of the wrist joint. Prolonged exposure may also result in kidney and brain damage. If the nervous system is affected, usually due to very high exposures,the resulting effects include severe headache, convulsions,coma, delirium, and death. In nonfatal cases, recovery isslow and not always complete. Alcohol ingestion and physical exertion may bring on symptoms. Lead exposureincreases the risk of high blood pressure.

Wear protective gloves andclothing to prevent any reasonable probability of skin contact. Use any barrier that will prevent contamination fromthe dust. Safety equipment suppliers/manufacturers can provide recommendations on the most protective glove/clothing material for your operation. All protective clothing(suits, gloves, footwear, headgear) should be clean, available each day, and put on before work. Work clothingshould be HEPA vacuumed before removal. Contact lensesshould not be worn when working with this chemical. Weardust-proof chemical goggles and face shield unless fullface-piece respiratory protection is worn. Employees shouldwash immediately with soap when skin is wet or contaminated. Provide emergency showers and eyewash.

This chemical is a noncombustiblesolid. Use dry chemical, carbon dioxide, water spray, oralcohol foam extinguishers. Poisonous fumes including leadare produced in fire. If material or contaminated runoffenters waterways, notify downstream users of potentiallycontaminated waters. Notify local health and fire officialsand pollution control agencies. Containers may explode infire. From a secure, explosion-proof location, use waterspray to cool exposed containers. If cooling streams areineffective (venting sound increases in volume and pitch,tank discolors, or shows any signs of deforming), withdrawimmediately to a secure position. If employees are expectedto fight fires, they must be trained and equipped in OSHA1910.156. The only respirators recommended for firefighting are self-contained breathing apparatuses that have fullface-pieces and are operated in a pressure-demand or otherpositive-pressure mode.
