Protective Equipment: Self-contained breathing apparatus, full protective clothing
Special Procedures: Keep out of drains and water sources, control runoff
Additional Hazards: Dust may ignite under specific conditions, containers may rupture under fire conditions
Personal Protection: Gloves, chemical goggles, dust mask, impervious clothing
Environmental Precautions: Prevent uncontained release to surface water and soil
Clean-Up Methods: Sweep up, avoid formation of dust, collect in sealable containers for proper disposal
Decontamination: Wash spill area with plenty of water, ventilate
Caution: Avoid inhaling dust, prevent spread beyond immediate area
Handling: Use with adequate ventilation, avoid dust generation, do not eat or drink in work area, wash hands after contact
Storage Conditions: Store in tightly closed containers, away from direct sunlight and moisture, in a cool dry area
Incompatibilities: Store away from oxidizers, strong acids, reducing agents
Technical Measures: Keep container tightly sealed when not in use, use explosion-proof equipment if dust generation likely

Incompatible Materials: Strong oxidizers, bases, acids, reducing agents
Hazardous Reactions: May react with strong agents to yield hazardous by-products
Acute Toxicity: Harmful by oral, dermal and inhalation exposure, LD50 values depend on specific intermediate, often 500-2000 mg/kg (oral, rat)
Skin Irritation: Causes irritation, possible sensitization on repeated contact
Eye Damage: Risk of mild-moderate irritation
Chronic Exposure: Data limited, precaution recommended, possible organ effects at high doses
Carcinogenicity: Not classified by IARC, evidence insufficient for direct link
Mutagenicity: No substantial genotoxicity reported for most synthetic intermediates, specific data varies by compound
Respiratory Effects: Inhalation may aggravate pre-existing respiratory problems
Ecotoxicity: Toxic to aquatic life at moderate concentrations, risk of bioaccumulation for some intermediates
Persistence and Degradability: Slowly biodegradable, variable based on structure, may persist in soil and water
Mobility: Tends to bind to soils, low volatility
Bioaccumulation: Bioaccumulation suspected for some organic intermediates
Other Adverse Effects: Limited data, recommend containment and treatment of effluent
