Suitable Extinguishing Media: Dry chemical, foam, sand; avoid using water jets directly on burning powder.
Unsuitable Extinguishing Media: Avoid water spray that may spread dust.
Hazardous Combustion Products: Hydrogen sulfide, sulfur dioxide.
Special Precautions: Firefighters should wear full protective clothing and self-contained breathing apparatus.
Explosion Risk: Dust clouds may explode if ignited in confined space.
Personal Precautions: Avoid breathing dust, ensure adequate ventilation, use protective gear.
Environmental Precautions: Prevent large amounts from entering waterways, sewers.
Clean-up Procedures: Sweep or shovel into suitable containers for recycling or disposal; use non-sparking tools.
Disposal: Dispose in accordance with local regulations.
Decontamination: Wash spill site with water after material pick-up is complete, avoid creating dust clouds.
Handling: Use in well-ventilated areas, avoid generating dust, ground/bond containers.
Personal Hygiene: Wash hands after handling, avoid eating or smoking around product.
Storage Conditions: Keep containers tightly closed in a cool, dry, well-ventilated area.
Storage Incompatibilities: Keep away from oxidizers, sources of ignition, acids.
Special Storage Requirements: Store in labeled containers, control access to trained staff.
Occupational Exposure Limit: None established for biological product; general dust limit applies (10 mg/m³ total inhalable dust, 5 mg/m³ respirable dust).
Engineering Controls: Use local exhaust ventilation, dust collectors, closed systems.
Personal Protective Equipment: NIOSH-approved respirator for dusty conditions, gloves (nitrile or neoprene), goggles or face shield, long sleeves and pants.
Environmental Controls: Collect dust at source, avoid discharge to environment.
Workplace Hygiene: Clean up regularly to avoid accumulation of dust.
Physical State: Solid (powder, granules, or micro-prills)
Color: Bright yellow to pale yellow
Odor: Faint characteristic smell, can be pungent if impure
Melting Point: 115 °C (239 °F)
Boiling Point: 445 °C (833 °F)
Solubility: Insoluble in water, soluble in carbon disulfide
Density: ~2.0 g/cm³
Vapor Pressure: Negligible under normal conditions
Flash Point: 190 °C (374 °F)
Chemical Stability: Stable under normal conditions, sensitive to high temperature and sparks.
Possibility of Hazardous Reactions: Contact with oxidizing agents may result in violent reactions.
Conditions to Avoid: Heat, open flames, sparks, static discharge, strong oxidizers, acids.
Hazardous Decomposition Products: Sulfur oxides, hydrogen sulfide.
Polymerization: Does not occur.
Reactivity: Reacts vigorously with strong oxidizing agents.
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Effects: Respiratory tract irritation from dust, mild skin or eye irritation.
Chronic Effects: Prolonged exposure may exacerbate asthma or bronchitis.
LD50 (oral, rat): > 5000 mg/kg (low toxicity)
Carcinogenicity: Not listed as carcinogenic by IARC, OSHA, or NTP.
Mutagenicity: No evidence in standard tests
Other Health Effects: May cause headache, dizziness at high dust concentrations.
Aquatic Toxicity: Low risk to aquatic life in normal use.
Persistence and Degradability: Elemental sulfur is slowly oxidized to sulfate by soil bacteria.
Bioaccumulative Potential: Not likely due to limited solubility and mobility.
Mobility in Soil: Low, but can move with erosion or runoff in large spills.
Other Adverse Effects: Large releases may disrupt local soil or water ecosystems temporarily; generally used as a soil amendment.
Waste Treatment Methods: Collect waste and contaminated material for approved landfill or incineration.
Container Disposal: Empty containers may contain residue; triple-rinse and recycle according to local laws.
Environmental Precautions: Avoid dispersing large amounts in waterways.
Regulatory Guidance: Follow local, regional, and national guidelines.
