Common Synonyms: Dyera costulata wood
CAS Number: Not assigned (natural product)
Recommended Use: Wood carving, pattern making, model construction
Supplier Details: Obtain directly from vendor or distributor, often sourced in Southeast Asia.
Emergency Telephone: Refer to supplier or national poison center for emergencies.
GHS Classification: Not classified as hazardous, but dust causes respiratory discomfort
Health Hazards: Dust can irritate eyes, nose, lungs; skin contact sometimes triggers dermatitis
Fire Hazards: Wood dust presents combustible dust hazard; vapors can build up in enclosed spaces
Label Elements: Avoid inhalation of dust, keep away from ignition sources, wash skin after handling
Signal Word: Warning
Precautionary Statements: Wear a mask, use gloves, practice industrial hygiene, control wood dust generation
Main Components: Cellulose, lignin, natural hydrocarbons
Natural Resins: Contains latex components, trace terpenoids
Impurities: Silicates, trace minerals depending on source
Percentage: Cellulose over 50%, lignin roughly 25-30%, latex varies by age and origin
Additives: No intentional additives; may absorb treatment chemicals if externally applied during shipment or storage
Inhalation: Remove to fresh air, rest, seek medical attention for breathing difficulty
Skin Contact: Wash thoroughly with water, remove contaminated clothing, use emollient if irritation persists
Eye Contact: Rinse cautiously for several minutes, remove contact lenses gently, seek medical advice if irritation remains
Ingestion: Rinse mouth, drink water to dilute, do not induce vomiting, consult a health professional
Note to Physician: Treat symptomatically, be aware of possible allergic reaction to latex components
Suitable Extinguishing Media: Dry chemical, foam, water spray, CO2 for smaller fires
Unsuitable Extinguishing Media: Avoid direct water jet on dust clouds
Hazardous Combustion Products: CO, CO2, irritating smoke, organic acids
Protective Equipment: Full protective gear, self-contained breathing apparatus for firefighting
Fire/Explosion Hazards: Fine dust suspended in air creates explosion risk, clear area and ventilate
Special Procedures: Remove nearby combustibles, cool containers, suppress dust formation
Personal Precautions: Wear mask, ventilate area, avoid contact with dust
Environmental Precautions: Prevent large releases from entering drains, sweep into containers
Cleanup Methods: Use non-sparking tools, reduce dust with gentle sweeping, dispose in accordance with local rules
Spill Containment: Isolate area, dampen spill to limit dust spread, control ignition sources
Safe Handling Advice: Minimize dust, keep tools sharp, use ventilation, avoid open flames
Hygiene Measures: Wash hands and exposed skin after working, keep work clothes separate
Storage Conditions: Store in cool, dry, well-ventilated space, away from oxidizers and ignition sources
Packing Materials: Stable, dry pallets or racks to prevent warping; wrap to reduce dust
Handling Precautions: Maintain good housekeeping, collect offcuts and dust in fire-safe containers
Occupational Exposure Limits: OSHA PEL for nuisance dust 15 mg/m3 (total), ACGIH TLV 1 mg/m3 for certain wood dusts
Engineering Controls: Local exhaust ventilation, dust extraction at source, HEPA filters
Personal Protective Equipment: Respiratory protection (N95 mask for dust), goggles, gloves, coveralls
Environmental Controls: Maintain workplace hygiene, dispose dust responsibly
Work Practices: Wet cutting preferred, avoid compressed air for dust removal
Appearance: Pale, light yellowish wood, fine and even grain
Physical State: Solid planks, logs, or blocks
Odor: Faint, sometimes slightly milky aroma from latex
pH (suspension): Neutral to slightly acidic
Boiling Point: Not applicable (solid)
Melting Point: Not applicable
Flash Point: Not precisely established, generally above 200°C for wood dust
Flammability: Readily combustible as dust
Solubility: Insoluble in water
Vapor Pressure: Not relevant
Density: 0.37–0.43 g/cm3 at 12% moisture content
Other Properties: Soft texture, low resin bleed under normal indoor conditions
Chemical Stability: Stable under normal conditions, degrades on extended moisture exposure
Reactivity: Does not react with most materials; avoid strong acids, bases, and oxidizers
Hazardous Reactions: Dust may form explosive mixtures in air
Decomposition Products: On burning, releases carbon monoxide, carbon dioxide, smoke
Incompatibility: Keep separate from sources of ignition, uncontrolled heat, and certain chemicals used in treatments
Routes of Exposure: Inhalation (dust), skin and eye contact
Acute Effects: Upper respiratory irritation, coughing, sneezing, skin rash in sensitive individuals
Chronic Effects: Persistent exposure to dust increases risk of respiratory conditions, possible allergenic reactions to latex
Carcinogenicity: Certain hardwood dusts classified as carcinogenic by IARC; Jelutong not specifically listed but best practice is to minimize dust inhalation
Other Effects: Eye irritation, skin dryness, dermal allergy symptoms in prolonged contact
Environmental Impact: Biodegradable, decomposes naturally in landfill
Ecotoxicity: No known significant effects in small quantities; dust not considered toxic
Mobility: Dust can spread locally via air, not water soluble
Persistence/Degradability: Breaks down over months to years into organic matter
Bioaccumulation: Not expected to bioaccumulate in wildlife
Special Considerations: Large wood debris disposal should not impact waterways or sensitive habitats
Disposal Methods: Reuse offcuts for fuel or compost, landfilling acceptable for clean wood, incinerate with controls
Waste Classification: Non-hazardous solid waste where uncontaminated
Special Precautions: Collect and contain dust in fire-resistant bags or bins, prevent from entering sewers
Regulatory Compliance: Follow local or national rules for wood and organic waste, manage treated wood separately
UN Number: Not regulated as dangerous goods
Transport Classification: Ordinary goods for domestic and international shipping
Label Requirements: None for untreated wood
Special Handling: Wrap or cover to limit dust release, secure bundles to prevent shifting
Storage in Transit: Dry and ventilated holds or containers recommended
Additional Notes: Treated wood may have separate requirements
Relevant Legislation: OSHA standards for wood dust, EPA guidelines for wood waste, IARC reporting for dust from certain woods
Health and Safety: Workplace exposure limits enforced for wood dust, local health agency notifications for workplace incidents
Environmental Regulations: National forestry and resource extraction laws apply for sourcing and exportation
Labelling: No mandatory hazard label for untreated Jelutong, advise dust hazard on storage
Other Compliance: Confirm with regional transport and waste disposal codes
