| | LEAD(II) ARSENATE Usage And Synthesis |
| Description | I ead arsenate is an odorless, heavy, whitepowder, or crystals. Molecular weight= 347.12; Freezing/Melting point = (decomposes) approximately 280℃. Also listed at 1042℃ (decomposes). Hazard Identific ation (basedon NFPA- 704 M Rating System): Health 3, Flammability 0,Reactivity 0. Insoluble in cold water; soluble in hot water. | | Chemical Properties | Lead arsenate is an odorless, heavy, white
powder, or crystals. | | Uses | Trilead Diarsenate was an inorganic insecticide used primarily on fruit orchards in the early 1900s, but is now officially banned as an insecticide. | | Potential Exposure | Used as an insecticide, herbicide, and
in manufacture of drugs; veterinary tapeworm medicine.
Incompatibilities: Violent reactions occur from contact
with oxidizers, chemically active metals; strong acids.
Acids and acid mists cause the release of arsine, a deadly
gas. Decomposes above 270C forming toxic fumes including arsenic and lead compounds | | First aid | If this chemical gets into the eyes, remove anycontact lenses at once and irri gate immediately for at least15 min, occasionally lifting upper and lower lids. Seek med-ical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, includ-ing resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medicalfacilty. When this chemical has been swallowed, get medi-cal attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.Note to physician: For severe poisoning BAL [British Anti-Lewisite, dimercaprol, dithiopropanol (C3HgOS2)] has beenused to treat toxic symptoms of certain heavy metals poi-soning including arsenic and may be of SOME value in thecase of lead poisoning. Although BAL is reported to have alarge margin of safety, caution must be exercised, becausetoxic effects may be caused by excessive dosage. Most canbe prevented by premedication with 1-ephedrine sulfate(CAS: 134-72-5). For milder poisoning penicillamine (notpenicillin) has been used, both with mixed success. Sideeffects occur with such treatment and it is never a substitutefor controlling exposure. It can only be done under strictmedical care.Persons with significant lead poisoning can be treated withCa EDTA while hospitalized. Since this drug causes a rushof lead from body organs into the blood and kidneys, andthus has its own hazards, it must be done by experiencedmedical persons under careful observation. It or other“che-lating”drugs should never be used to prevent poisoningwhile exposure continues, as severe kidney damage canresult. | | storage | 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. Lead arsenate must be stored to avoid contact withoxidizers (such as perchlorates, perox ides, permanganates,chlorates and nitrates) and chemically active metals (suchas potassium, sodium, magnesium, and zinc), since violentreactions occur. Avoid the presence of acids since arsine, avery deadly gas, is released in the presence of acid or acidmist. A re gulated, marked area should be established wherethis chemical is handled, used, or stored in compliance withOSHA Standard 1910.1045. A regulated, marked areashould be established where this chemical is handled, used,or stored in compliance with OSHA Standard 1910. 1045. | | Shipping | UN1617 Lead arsenates, Hazard Class: 6.1;
