General Description
Faintly pink wet crystals with an odor of vinegar. (USCG, 1999)
Hazards
Reactivity Alerts
- Strong Oxidizing Agent
- Water-Reactive
Air & Water Reactions
Unstable in air. Reacts with water to form brown lead dioxide and acetic acid [Merck 11th ed. 1989].
Fire Hazard
Behavior in Fire: Can increase the intensity of a fire when in contact with combustible material. Cool containers with plenty of water. (USCG, 1999)
Health Hazard
Early symptoms of lead intoxication by ingestion are most commonly gastrointestinal disorders, colic, constipation, etc.; weakness, which may go on to paralysis chiefly of the extensor muscles of the wrists and less often of the ankles, is noticeable in the most serious cases. Ingestion of a large amount causes local irritation of the alimentary tract; pain, leg cramps, muscle weakness, paresthesias, depression, coma, and death may follow in 1 or 2 days. Contact causes severe irritation of eyes and can burn skin. (USCG, 1999)
Reactivity Profile
Lead tetraacetate is a metal carboxylate salt. It is commonly used as an oxidizing agent in organic chemistry.
Belongs to the Following Reactive Group(s)

Response Recommendations
Isolation and Evacuation
Excerpt from 151
[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
Excerpt from 151
[Substances - Toxic (Non-Combustible)]:
SMALL FIRE: Dry chemical, CO2 or water spray.
LARGE FIRE: Water spray, fog or regular foam. If it can be done safely, move undamaged containers away from the area around the fire. Dike runoff from fire control for later disposal. Avoid aiming straight or solid streams directly onto the product.
FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn. (ERG, 2020)
Non-Fire Response
Neutralizing Agents for Acids and Caustics: Dilute with water, rinse with dilute sodium bicarbonate or lime solution. (USCG, 1999)
Protective Clothing
Goggles or face shield; rubber gloves (USCG, 1999)

First Aid
Remove at once all cases of lead intoxication from further exposure until the blood level is reduced to a safe value; immediately place the individual under medical care.
INGESTION: give gastric lavage using 1% solution of sodium or magnesium sulfate; leave 15-30 gm magnesium sulfate in 6-8 oz. of water in the stomach as antidote and cathartic; egg white, milk, and tannin are useful demulcents; atropine sulfate and other antispasmodics may relieve abdominal pain, but morphine may be necessary.
EYES: flush with water for at least 15 min.
SKIN: wash contaminated skin with large amounts of water for 15 min. (USCG, 1999)
