General Description
Powdery white solid with a slight fatty odor. Sinks in water. (USCG, 1999)

Hazards

Reactivity Alerts
none
Air & Water Reactions
Insoluble in water.
Fire Hazard
Special Hazards of Combustion Products: At high temperature toxic fumes are emitted.

Behavior in Fire: Possibility of explosion exists under dusty conditions (USCG, 1999)
Health Hazard
INHALATION: Joint and muscle pains, headache, dizziness, and insomnia. Weakness, frequently of extensor muscles of hand and wrist (unilateral or bilateral). Heavy contamination - brain damage. Stupor progressing to coma - with or without convulsion, often death. Excitation, confusion and mania less common. Cerebrospinal pressure may be increased. INGESTION: Abdominal pain, diarrhea, constipation, loss of appetite, muscular weakness, headache, blue line on gums, metallic taste, nausea, and vomiting. (USCG, 1999)
Reactivity Profile
LEAD STEARATE has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.
Belongs to the Following Reactive Group(s)

Response Recommendations

Isolation and Evacuation
Excerpt from 151 Polymerizable warning [Substances - Toxic (Non-Combustible)]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.

SPILL: Increase the immediate precautionary measure distance, in the downwind direction, as necessary.

FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2020)
Firefighting
Fire Extinguishing Agents: Chemical, foam, CO2, water (fog) (USCG, 1999)
Non-Fire Response
Excerpt from 151 Polymerizable warning [Substances - Toxic (Non-Combustible)]:

Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. Cover with plastic sheet to prevent spreading. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS. (ERG, 2020)
Protective Clothing
Dust and/or fume respirator, gloves, goggles or safety glasses, coveralls, and cap. (USCG, 1999)

First Aid
Call a physician.

INHALATION: Remove from the source of exposure. Keep victim quiet and warm.

EYES: Wash with water for 15 to 20 minutes.

SKIN: Wash with soap and water.

INGESTION: Call a physician at once. Induce vomiting, give milk and magnesium sulfate (epsom salts). (USCG, 1999)
