Signal Word: Danger
Pictograms: Corrosive, Acute Toxicity, Environmental Hazard
Routes of Entry: Inhalation, ingestion, skin and eye contact present significant danger
Symptoms: Severe pain, redness, blistering, cough, shortness of breath, eye watering, vision damage
Chronic Effects: Frequent exposure may cause long-term skin sensitivity, lung damage, or vision issues
Chemical Name: Phosphorus Oxybromide
CAS Number: 7789-59-5
EC Number: 232-181-8
Concentration: 99% or greater for chemical grade sample
Impurities: May include trace phosphorus tribromide or phosphorus oxychloride if present during synthesis, which can influence toxicity and reactivity
Inhalation: Remove person to fresh air, keep quiet and warm, seek immediate medical attention, administer oxygen if trained
Skin Contact: Remove contaminated clothing, flush skin with copious amounts of water for at least 15 minutes, do not delay treatment
Eye Contact: Flush eyes gently yet thoroughly with water for at least 15 minutes, lifting eyelids, seek emergency medical evaluation
Ingestion: Do not induce vomiting, rinse mouth with water, immediately contact poison center or emergency department
Advice to Doctor: Treat for corrosive poisoning, manage airway compromise promptly, periodic monitoring of pulmonary function recommended
Suitable Extinguishing Media: Use dry chemical, CO2, or foam, avoid water streams directly on product
Unsuitable Media: Avoid water, as it reacts violently releasing toxic fumes
Combustion Byproducts: Phosphorus oxides, bromine vapors, hydrogen bromide
Special Equipment: Recommend self-contained breathing apparatus, chemical-resistant suit
Fire Hazards: Reacts with water and moisture, generates heat and poisonous gases, avoid confined spaces
Instructions: Approach from upwind, avoid inhalation of smoke or fumes, evacuate unnecessary personnel from area
Personal Precautions: Evacuate area, wear positive pressure self-contained respirators, protective clothing, avoid skin and eye exposure
Environmental Precautions: Prevent from entering drains, surface water, or soil
Containment: Dike spilled material with sand or inert absorbent, do not use organic or combustible materials for cleanup
Cleanup Procedures: Collect spillage using spark-resistant, corrosion-proof tools, store in appropriate chemical waste containers, decontaminate area using weak base (sodium bicarbonate) if safe
Secondary Hazards: Avoid all sources of ignition, ventilate the area well
Handling: Use only in fume hood, ensure all handlers are trained in proper chemical safety, avoid contact with skin, eyes, or clothing, always open containers slowly and away from face
Storage: Store in cool, dry, tightly closed containers made of glass or compatible materials, label clearly, keep segregated from water sources, bases, reducing agents and organic materials
Special Remarks: Check containers regularly for leaks or signs of deterioration, maintain access to safety showers and eyewash stations in storage and handling areas
Exposure Limits: No specific OSHA or ACGIH limits, control exposure by using best available engineering controls
Engineering Controls: Use chemical fume hoods, local exhaust ventilation, prevent aerosol formation
Personal Protection: Wear full chemical splash goggles, face shield, chemical-resistant gloves (viton, neoprene), lab coat or apron, appropriate respiratory protection if ventilation is insufficient
Hygiene Measures: Wash hands thoroughly before breaks, at shift end, avoid eating or drinking in handling area
Appearance: Fuming, colorless to pale yellow liquid with pungent odor
Odor: Sharp, suffocating, similar to acidic bromine vapors
Boiling Point: Approximately 193°C
Freezing Point: About 3°C
Density: 2.53 g/cm3
Vapor Pressure: Moderate at room temperature
Solubility: Reacts violently with water forming phosphoric and hydrobromic acids
pH: Not applicable (reacts hydrolytically)
Partition Coefficient: Not determined
Viscosity: Low to moderate
Reactivity Profile: Notable for releasing fumes in air due to reaction with atmospheric moisture
Chemical Stability: Stable under recommended storage and handling conditions away from moisture
Hazardous Reactions: Intense reaction with water and steam, violent hydrolysis with release of toxic gases
Incompatible Materials: Water, alcohols, bases, reducing agents, organic solvents, combustible materials
Decomposition: Produces bromine vapors, phosphorus oxides, hydrobromic acid fumes under heat or in contact with incompatible substances
Acute Toxicity: Highly toxic if inhaled, ingested, or exposed to skin, estimated LD50 values through oral/dermal routes are low (animal data)
Corrosive Effects: Severe burns to skin, eyes, gastrointestinal tract, respiratory system
Inhalation Exposure: May result in laryngeal edema, bronchospasm, possible respiratory failure or death with concentrated exposure
Chronic Toxicity: Repeated or prolonged exposure increases risk of chronic lung, skin, and eye damage
Sensitization: No data showing allergic response but risk should not be discounted
Carcinogenicity: No recognized classification by OSHA, NTP, IARC; still, severe corrosive nature means strict exposure prevention is required
Aquatic Toxicity: Causes acute toxicity in aquatic organisms, due to acidification and brominated byproducts
Persistence: Hydrolyzes quickly, products are environmentally hazardous
Bioaccumulation: Not known to bioaccumulate, but the breakdown products can cause significant long-term environmental damage
Soil Mobility: High reactivity with soil moisture, potential acidification and groundwater contamination
Precautions: Prevent release into waterways and drains, report large spills to environmental authorities promptly
Disposal Methods: Neutralize cautiously with dilute base in controlled fume hood, transfer to approved chemical waste containers
Waste Classification: Hazardous waste under local, state, federal guidelines
Containers: Do not reuse without thorough decontamination, send all contaminated materials for hazardous disposal
Regulatory Compliance: Follow all hazardous waste disposal regulations and documentation standards, consult licensed waste disposal operators
