Inhalation: Move affected person to fresh air; administer oxygen if breathing is difficult; seek immediate medical attention if symptoms persist
Skin Contact: Remove contaminated clothing; wash affected area with soap and plenty of water for at least 15 minutes; seek medical advice for persistent irritation or allergic response
Eye Contact: Rinse immediately with plenty of water for at least 20 minutes, holding eyelids open; consult an ophthalmologist
Ingestion: Rinse mouth with water; never induce vomiting unless instructed by medical personnel; seek medical attention promptly
Most Important Symptoms: Redness, itching, rash, eye watering, gastrointestinal upset
Immediate Medical Attention: Critical in cases of respiratory symptoms or persistent eye discomfort
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, appropriate foam, water spray
Unsuitable Extinguishing Media: High-pressure water jets
Specific Hazards: Vapors can form explosive mixtures with air; combustion may generate toxic fumes including carbon monoxide, carbon dioxide, and soot
Special Protective Equipment: Firefighters require self-contained breathing apparatus and heat-resistant clothing to manage potential toxic emissions
Advice for Firefighters: Remove containers from fire area if safe; douse with water to cool in the case of intense heat or rupture
Personal Precautions: Isolate spill area; wear gloves, goggles, and chemical-resistant clothing; prevent inhalation of dusts or fumes
Environmental Precautions: Contain spill to prevent entry into drains or watercourses; notify authorities in case of contamination
Methods for Clean-Up: Absorb spills with inert material like sand or vermiculite; collect material and waste in suitable, labeled containers for proper disposal; ventilate area thoroughly after cleanup
Handling: Utilize with proper engineering controls such as fume hoods or local exhaust systems; handle in areas with adequate ventilation; avoid skin and eye contact and ingestion
Storage: Keep in tightly closed containers, labeled correctly; store in a dry, cool location away from direct sunlight, heat sources, oxidizing agents, and strong acids or bases
Specific Storage Requirements: Segregate from incompatible substances; maintain temperature stability to protect product and user
Engineering Controls: Local exhaust ventilation or process enclosure to minimize airborne exposure
Personal Protective Equipment: Impermeable protective gloves (nitrile or neoprene), goggles with side shields, lab coat or coveralls, proper footwear; if risk of inhalation exists, use certified respirators
Hygiene Measures: Maintain clean work environment; do not eat, drink, or smoke while handling; wash thoroughly after use
Occupational Exposure Limits: No established OSHA or ACGIH limits; best industry practices recommend keeping airborne concentrations as low as feasibly possible
Appearance: White to off-white crystalline solid
Odor: Faint aromatic or ether-like
pH (aqueous solution): Typical range 6.0–8.0
Melting Point: 102–106°C
Boiling Point: Decomposes before boiling
Flash Point: >125°C (closed cup)
Solubility: Slightly soluble in water; readily soluble in ethanol, acetone, and other organic solvents
Density: 1.19 g/cm³
Vapor Density: Not established; heavier than air
Other Properties: Stable under normal storage and handling; not corrosive to metals
Chemical Stability: Stable under recommended storage conditions
Reactivity: Reacts with strong oxidizers and acids; can form hazardous byproducts on thermal decomposition
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, potentially small-molecule aromatic hydrocarbons
Conditions to Avoid: Exposure to strong sunlight, excessive heat, and incompatible chemicals
Incompatible Materials: Oxidizing agents, acids, bases, reducing agents
Acute Toxicity: LD50 (oral, rat): estimated >200 mg/kg; may cause gastrointestinal upset
Skin Irritation: May cause redness, swelling, or rash on prolonged contact
Eye Effects: Irritation, watering, pain, conjunctival inflammation
Respiratory Effects: Inhalation of dust may irritate mucous membranes or trigger asthma-like symptoms in sensitized individuals
Chronic Exposure: No long-term studies reported; best approach is prudent avoidance of prolonged or repeated exposure
Sensitization: Possible in sensitive persons with repeated skin contact
Carcinogenicity: Not classified as carcinogenic by IARC, NTP, or OSHA to date
Reproductive Toxicity: No data available from animal or human studies
Mutagenicity: Not classified as mutagenic based on chemical structure and limited testing
Ecotoxicity: Toxic to aquatic life at sufficient concentrations; avoid releases to the environment
Persistence and Degradability: Not rapidly biodegradable; potential for persistence in soil and water
Bioaccumulation Potential: Moderate; chemical structure suggests potential for bioaccumulation in aquatic organisms
Mobility in Soil: Moderately mobile, may leach to groundwater in significant spills
Other Adverse Effects: May disrupt microbial communities in soil and water
Waste Treatment Methods: Handle as hazardous chemical waste; use approved incineration or chemical treatment methods
Disposal of Material: Collect waste in sealed, labeled containers; send for disposal at licensed hazardous waste facility
Disposal of Packaging: Contaminated containers require thorough cleaning or should be disposed of as chemical waste; observe all local laws
Precautions: Do not flush into drains; avoid environmental contamination through improper disposal
