Environmental Precautions: Prevent release to soil, surface water, and drains
Methods for Containment: Collect spillage with non-combustible absorbent material (such as sand or earth)
Methods for Cleaning Up: Sweep up and transfer to a labeled waste container, ventilate area, clean thoroughly with water and detergent after removal
Reference to Other Sections: Safe disposal guidelines, personal protection advice must be followed as indicated elsewhere in this document
Precautions for Safe Handling: Handle in a well-ventilated place, avoid dust generation, avoid contact with skin and eyes, refrain from eating, drinking, or smoking during use, wash thoroughly after handling
Conditions for Safe Storage: Store in tightly closed original container, keep away from sources of ignition, moisture, strong acids and bases, and out of direct sunlight
Incompatible Materials: Strong oxidizing agents, acids and alkalis, avoid exposure to reactive substances
Other Requirements: Store in designated chemical storage areas, maintain at recommended storage temperature, clearly label containers
Exposure Limits: No established occupational exposure limit for this substance
Engineering Controls: Use fume hood or local exhaust ventilation to minimize airborne dust
Personal Protective Equipment: Chemical-resistant gloves, safety goggles, lab coat or protective clothing
Respiratory Protection: NIOSH/MSHA approved respirator required if dust is generated
Environmental Controls: Avoid contamination of drains and environment, install spill containment measures
Appearance: White to light yellow crystalline powder
Odor: Slight phenolic odor
Melting Point: 127–131°C (260–267°F)
Boiling Point: Not determined, decomposes before boiling
Solubility: Insoluble in water, soluble in organic solvents like acetone, benzene, and toluene
Vapor Pressure: Negligible at room temperature
Density: 1.08–1.12 g/cm³ at 20°C
pH: Not applicable
Partition Coefficient (log Kow): Estimated at over 4, indicating high potential for bioaccumulation
Stability: Stable under normal storage and handling conditions
Thermal Decomposition: Produces toxic fumes, including sulfur oxides and carbon oxides, at temperatures above melting points
Reactivity: Not reactive under standard use
Incompatible Materials: Avoid contact with oxidizing agents, acids, alkalis
Hazardous Polymerization: Does not polymerize
Hazardous Decomposition Products: Sulfur-containing gases, carbon monoxide, carbon dioxide may be released under fire conditions
Routes of Exposure: Absorption through skin, inhalation, ingestion, direct eye contact
Acute Toxicity: Low systemic toxicity; estimated oral LD50 in rats exceeds 5,000 mg/kg (practically non-toxic on acute basis)
Skin and Eye Irritation: Causes irritation and redness on contact
Inhalation: Dust may cause irritation of the respiratory tract, cough, headaches, dizziness if inhaled in large amounts
Chronic Effects: Prolonged and repeated contact might cause dermatitis or sensitization
Carcinogenicity: Not classified as carcinogenic based on available information
Reproductive/Developmental Effects: No evidence of reproductive toxicity in standard studies
Additional Information: Animal studies suggest minimal target organ toxicity when used under recommended exposure levels
Ecotoxicity: Harmful to aquatic organisms, potential for long-term adverse effects in aquatic environments
Persistence and Degradability: Slowly biodegradable, persistent in soil and sediment
Bioaccumulation: High potential based on partition coefficient, accumulates in aquatic and terrestrial species
Mobility in Soil: Low solubility in water leads to minimal migration in soil, tends to remain near point of release
Other Harmful Effects: Not expected to contribute to ozone depletion or global warming, but careful handling minimizes risk to ecosystems
Waste Treatment Methods: Incinerate in accordance with local, regional, or national regulations, do not dispose through sewage or household waste
Container Disposal: Empty containers should be triple-rinsed, punctured, and sent to approved waste site
Special Precautions: Avoid release to the environment, any leftover or waste product must be treated as hazardous chemical waste and disposed of accordingly
