Product Name: Lead Bromate
Chemical Formula: Pb(BrO3)2
CAS Number: 13453-07-1
Synonyms: Lead(II) bromate
Recommended Use: Laboratory chemical, research, chemical synthesis
Supplier Details: Chemical manufacturers and distributors offer lead bromate mostly for scientific purposes. Emergency contact information should be on the chemical container.
Hazard Classification: Toxic by ingestion, inhalation, and skin contact; oxidizer; suspected carcinogen; harmful to aquatic life
GHS Label: Skull and crossbones, exclamation mark, environmental hazard, oxidizer symbols
Hazard Statements: Causes damage to organs (nervous system, kidneys, blood) through prolonged or repeated exposure; serious eye and skin irritant; may cause cancer; may intensify fire due to its oxidizing nature; very toxic to aquatic organisms
Precautionary Statements: Avoid breathing dust or fumes; wear protective gloves and eye protection; avoid release to the environment; use only outdoors or in a well-ventilated area
Substance: Lead Bromate
Chemical Formula: Pb(BrO3)2
Purity: Usually > 98% for laboratory use
Impurities: Trace heavy metals possible, check with supplier for exact breakdown
Molecular Weight: 455.83 g/mol
Inhalation: Move victim to fresh air immediately; seek medical attention if symptoms like headache, dizziness, nausea, or coughing occur; give oxygen if breathing is difficult.
Skin Contact: Remove contaminated clothing and wash affected skin with plenty of soap and water for at least 15 minutes; do not use solvents; get medical help if irritation develops.
Eye Contact: Rinse cautiously with plenty of water for several minutes; remove contact lenses if present; continue flushing; obtain medical attention, as lead bromate exposure to eyes may cause severe irritation or damage.
Ingestion: Do not induce vomiting unless instructed by medical personnel; rinse mouth; drink water if conscious; seek medical help immediately, as ingestion can result in lead poisoning.
Suitable Extinguishing Media: Use water spray, foam, or dry chemical; do not use carbon dioxide directly on lead bromate fires
Special Hazards: Lead bromate acts as a strong oxidizer and may intensify fire; decomposes to release toxic fumes of lead oxides and bromine compounds
Protective Equipment: Full turnout gear and positive-pressure self-contained breathing apparatus are mandatory; avoid inhaling vapors or dust
Advice for Firefighters: Approach from upwind; cool containers with water spray to prevent explosion or rupture
Personal Precautions: Evacuate area; ventilate space; wear suitable protective gear including respirator, gloves, and chemical-resistant clothing
Environmental Precautions: Avoid discharge into drains, watercourses, or soil; contain spills with sand or inert material to avoid environmental contamination
Methods for Clean Up: Carefully sweep or scoop up material; place in a closed, labeled container for hazardous waste disposal; use a vacuum with HEPA filter if available; do not create dust; wash contaminated area with water and detergent after material is picked up
Handling: Operate in a chemical fume hood; avoid contact with skin, eyes, and clothing; keep container tightly closed; never mix with organic materials or reducers due to oxidizing properties; avoid generation of dust
Storage: Store in a cool, dry, well-ventilated area away from sunlight and sources of ignition or heat; segregate from acids, organics, easily oxidizable materials, and reducers; keep in original container, tightly closed and clearly labeled with hazard symbols; ensure the storage area is equipped for handling lead compounds and has secondary containment
Engineering Controls: Use chemical fume hood or local exhaust ventilation; provide eyewash stations and safety showers in the immediate work area
Exposure Limits: OSHA PEL (Lead, inorganic compounds): 0.05 mg/m3 (as Pb), NIOSH REL: 0.05 mg/m3; no established limit for bromate but treat as highly hazardous
Personal Protective Equipment: Wear gloves (nitrile or neoprene), flame-resistant lab coats, safety goggles, and, if exposure risk is high, full-face shield and respiratory protection with particulate and vapor filters
Hygiene Measures: Wash hands thoroughly after handling; do not eat, drink, or smoke while using; remove contaminated clothing and launder before reuse
Appearance: White crystalline solid or powder
Odor: Odorless
Melting Point: Decomposes without melting
Solubility: Slightly soluble in water
Specific Gravity: Data not widely available; estimate higher than 4 due to lead content
pH: Neutral to slightly basic in dilute solution
Vapor Pressure: Negligible at room temperature
Other Properties: Strong oxidizer; stable under normal conditions if kept dry; decomposes releasing bromine and oxygen when heated
Chemical Stability: Stable in dry, cool, and inert atmosphere
Conditions to Avoid: Heat, moisture, contact with organic materials, acids, and reducing agents
Incompatible Materials: Strong acids, metals, organic substances, powdered metals, sulfides, phosphorous, and combustibles
Hazardous Decomposition Products: Toxic fumes of lead oxides, bromine, and other bromine oxides
Possibility of Hazardous Reactions: Reacts violently with reducing agents and organics, risk of explosion or fire
Acute Effects: May cause severe irritation to eyes, skin, and respiratory tract; ingestion can result in abdominal pain, nausea, vomiting, diarrhea, and acute lead poisoning
Chronic Effects: Exposure can result in neurological disorders, anemia, kidney damage, reproductive toxicity, cancer; bromate is classified as a possible human carcinogen
Routes of Exposure: Inhalation of dust, skin absorption, ingestion, eye contact
Symptoms: Weakness, fatigue, abdominal pain, muscle and joint pain, cognitive impairment from chronic exposure
Medical Conditions Aggravated: Kidney disorders, blood disorders, nervous system conditions
Carcinogenicity: Classified as hazardous by IARC and similar agencies for chronic lead and bromate exposure
Aquatic Toxicity: Extremely toxic to aquatic life even in small quantities; may cause long-term damage to aquatic environments
Persistence and Degradability: Lead does not degrade; bromate anion may persist until reduced; bioaccumulates in organisms
Mobility: Moderate, but heavy lead compound tends to settle
Bioaccumulation: High potential due to lead
Other Adverse Effects: Can disrupt aquatic food chains, contaminate water supplies, bioaccumulate in plants/animals leading to public health risks
Disposal Methods: Treat as hazardous waste; follow local, regional, and national regulations strictly; transfer waste to a licensed hazardous waste disposal contractor
Contaminated Packaging: Dispose after decontamination or as hazardous waste
Precautions: Never dispose to drain, watercourses, or regular landfill due to extreme toxicity and persistence in the environment; incineration not recommended due to formation of lead fumes; record keeping and waste tracking required for regulatory compliance
UN Number: UN 3077 (Environmentally Hazardous Substance, Solid, n.o.s.)
Transport Hazard Class: 9 (Miscellaneous dangerous substances, strong oxidizer)
Packing Group: III
Label Requirements: Toxic, Environmentally Hazardous Substance, Oxidizer
Special Precautions for User: Secure upright, keep separate from food, acids, flammable, and reducing agents; must be transported according to hazardous materials rules; emergency procedures outlined in shipping documents
