| Hazard Information | Back Directory | [Chemical Properties]
white or off-white powder | [Potential Exposure]
Lead sulfate is used in storage batteries and paint pigments. Used in the making of alloys, fastdrying oil varnishes; weighting fabrics; in lithography | [First aid]
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. 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.
If this chemical gets into the eyes, remove any contact
lenses at once and irrigate immediately for at least 20 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medical attention. Do not induce vomiting | [Shipping]
UN2291 Lead compounds, soluble n.o.s., Hazard
Class: 6.1; Labels: 6.1-Poisonous materials, Technical
Name Required. UN1794 Lead sulfate with more than 3%
free acid, Hazard class: 8; Labels: 8-Corrosive material.
UN3077 Environmentally hazardous substances, solid, n.o.
s., Hazard class: 9; Labels: 9-Miscellaneous hazardous
material, Technical Name Required | [Incompatibilities]
Incompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,
bromine, fluorine, etc.); contact may cause fires or explosions. Contact with potassium can cause explosion. Keep
away from alkaline materials, strong bases, strong acids,
oxoacids, and epoxides | [Uses]
Applications for tribasic lead sulfate stabilizers include thermal stabilization of flexible PVC wire insulation compounds containing phthalate-type plasticizers, wire insulation designed to meet Underwriters Laboratories specifications through 80 C, rigid and flexible PVC foams, rigid vinyl profiles, and PVC plastisols. The usual range of tribasic lead sulfate required in PVC is between two and seven parts per hundred of resin (2 7 phr), depending on the intended application of the vinyl product. | [Flammability and Explosibility]
Notclassified | [Synthesis]
1. Waste lead paste is washed with water to remove acid.
2. Deacidified lead paste and lead oxide powder are added to hot water in a specific ratio to form a slurry.
3. Dilute sulfuric acid is added dropwise to the slurry at 75-80°C. After holding t |
