Name: Diethylmercury Phosphate
Chemical Structure: Organomercury phosphate compound; contains mercury atom bonded to two ethyl groups and one phosphate group
Rarely encountered in typical industry use, mostly of academic or specialized research interest due to high toxicity and volatility
Physical Form: Typically a liquid at standard temperature, often clear, slightly oily
Acute Toxicity: Extremely poisonous if inhaled, swallowed, or absorbed through the skin
Major Health Risks: Causes severe systemic poisoning, attacking the nervous system, kidneys, and liver; exposure may result in tremors, memory loss, and potentially fatal respiratory or cardiac failure
Environmental Danger: Highly toxic to aquatic life and persists in water and soil, leading to long-term environmental harm
Routes of Exposure: Skin contact, breathing vapors, ingestion, or accidental injection; vaporizes easily
Main Ingredient: Diethylmercury Phosphate
Mercury Content: High (mercury makes up significant molecular mass, contributing to acute toxicity)
Additional Compounds: No significant stabilizing additives or impurities reported due to its preparative method and limited practical applications
Inhalation: Get to fresh air right away; breathing difficulty almost always implies immediate medical emergency; administer oxygen and artificial respiration if breathing ceases
Skin Contact: Remove contaminated clothing; wash thoroughly with soap and water, paying close attention to cuticles and nails where residue can hide
Eye Contact: Rinse eyes with water for many minutes; keep eyelids moving and remove contact lenses if present; do not rub
Ingestion: Seek medical attention instantly; do not induce vomiting—risk of further damage or aspiration
Medical Treatment: Immediate hospitalization; chelating agents like dimercaprol sometimes used, though effectiveness can vary; advanced medical monitoring required
Suitable Extinguishing Media: Dry chemical, carbon dioxide, or foam; water can spread contamination if compound disperses
Fire Risks: Decomposition under high heat can release toxic mercury fumes and phosphorous oxides
Protective Equipment: Wear positive pressure self-contained breathing apparatus; full protective gear essential due to poisonous smoke
Combustion Products: Harmful gases released, making evacuation of area critical
Personal Protection: Evacuate non-essential personnel immediately; don chemical-resistant gloves, goggles, and full-body suit with respirator
Containment: Absorb spills with materials that do not react (such as clay or vermiculite); avoid using sawdust which can ignite or degrade
Disposal of Debris: Scoop residues into leak-proof hazardous waste containers; avoid runoff; wash area with mercury-specific decontaminants only
Decontamination: Check surfaces with mercury vapor analyzer; secondary wash with sulfur dust or specific binders often required
Handling: Only trained professionals in controlled ventilation areas; Mercury contamination is cumulative, and small spills build up risk
Avoiding Exposure: Never touch bare skin; keep away from heat, sparks, open flame or incompatible materials; always work under fume hoods
Storage Conditions: Store in tightly closed glass containers, placed in ventilated, locked chemical cabinets specifically separate from acids, bases, and flammable goods; label containers boldly
Engineering Controls: Local exhaust ventilation a must; fume hoods fitted with mercury vapor detectors recommended
Personal Protective Equipment: Acid-resistant gloves (such as butyl or nitrile), lab coat or Tyvek suit, eye protection, and, for large scale work, full face mask respirator
Hygiene Measures: Never eat, drink, or smoke in work areas; wash hands and face after use; special mercury decontamination soap may help prevent chronic exposure
Biological Monitoring: Regular urinalysis for mercury, especially for workers frequently handling it
Appearance: Colorless to pale yellow oily liquid
Odor: Mildly sweet, but acrid; strong vapor suggests extreme danger
Boiling Point: High; volatile enough for small amounts to evaporate at room temperature
Solubility: Low in water; mixes with organic solvents more so
Vapor Pressure: Moderate for a mercury compound, meaning it becomes airborne easily
Density: Higher than water, sinks in most liquids
Chemical Stability: Stable in cool, dark, and dry locations; light or heat prompts decomposition
Reactivity: Violent reaction with strong oxidizers, some acids, and certain metals; forms toxic fumes if burned
Hazardous Decomposition: Mercury vapors and phosphorus oxides among the worst; inhaling these causes nearly instant harm
Mercury Poisoning: Causes severe neurotoxicity; psychiatric disturbances, cognitive loss, rapid onset of kidney and liver failure
Skin Effects: Penetrates skin rapidly, making gloves and long sleeves absolutely necessary
Chronic Exposure: Symptoms develop over time and may include chronic headaches, tremors, loss of coordination, and long-term organ damage; fetal effects possible during pregnancy
Fatal Dose: Tiny quantities can kill—main reason for strict lab controls
Aquatic Impact: Highly poisonous to fish, insects, and other aquatic creatures
Persistence: Mercury compounds stick around for decades; they build up in food chains causing biomagnification
Clean-up Difficulty: Natural breakdown is so slow that contamination can last a lifetime in soils and waterways
Preferred Disposal: Collection by licensed hazardous waste handler; chemical incineration at high temperatures in specialized facilities only
Drains or Landfill: Never pour down sinks or toss in regular trash, fines and criminal penalties result; even micrograms unwanted in municipal water
Packaging: Triple containment, rigid closure, clear labeling as “High Toxicity: Organomercury Compound”; keep in isolated storage before removal
Regulated Commodity: Only shipped under hazardous goods protocol; likely considered Class 6.1 (Toxic Substances)
Packaging Requirements: Sealed glass, secondary containment, shock-absorbing materials in closed, locked crates
Transport Route: Movement requires permits, advance notification to authorities, and documentation for chain-of-custody
Environmental Law: Mercury compounds appear on international lists of hazardous pollutants under conventions like the Minamata Convention
Occupational Limits: Exposure standards usually measured in micrograms per cubic meter; exceeded rapidly without controls
Restricted Access: Not for public sale; strict regulations for laboratory, research, and very limited industrial applications
Reporting Requirements: Any spill or release triggers mandatory reporting to local environmental and health authorities due to severity
