Signal Word: Warning
Symbol: Exclamation Mark
Precautionary Statements: Avoid breathing dust; wear protective clothing, gloves, and eye/face protection; wash hands thoroughly after handling
Physical Hazards: Fine powder may present dust explosion risk in strong concentrations
Health Hazards: Sensitization on repeated inhalation; existing respiratory or skin conditions can be aggravated
Environmental Hazards: Considered low environmental hazard, but bulk spills may have localized effects
Main Ingredient: β-Mannanase enzyme protein
Concentration: Active enzyme typically ranges from 1% to 10% by weight, remainder includes stabilizers
Other Components: Sodium chloride (3–7%), inert carriers such as cellulose or maltodextrin (up to 80%), water (variable)
Preservatives: Trace amounts of sodium benzoate or potassium sorbate may be present
Impurities: Possible trace residues from microbial fermentation process, all below regulatory threshold
Inhalation: Remove individual to fresh air, support breathing as needed, seek medical attention if symptoms persist or become severe
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing, medical attention if irritation develops
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes while holding eyelids open, seek medical attention if irritation continues
Ingestion: Rinse mouth, give water to drink if victim is conscious, never induce vomiting, consult medical professional
Self-Protection: First responders should use gloves and avoid dust inhalation during all rescue measures
Suitable Extinguishing Media: Use carbon dioxide, water spray, dry chemical, or foam
Unsuitable Media: Avoid high pressure water jets, which can spread dust
Hazardous Combustion Products: Burning may release carbon monoxide, nitrogen oxides, and small amounts of toxic fumes
Advice for Firefighters: Wear full protective clothing including self-contained breathing apparatus
Specific Dangers: Dust can form explosive mixtures with air under certain conditions; follow standard powder handling precautions in fire events
Personal Precautions: Evacuate unnecessary personnel, ventilate area, avoid breathing dust, wear appropriate PPE (gloves, N95 mask or P2 respirator, safety goggles)
Environmental Precautions: Prevent entry into drains, surface and groundwater; containment is key for large spills
Spill Cleanup Methods: Use vacuum equipped with HEPA filter or damp sweeping, collect in sealable containers for disposal
Decontamination: Wash spill site with water after clean-up, avoid generating aerosols
Safe Handling Advice: Minimize dust generation and accumulation, keep containers tightly closed, use outside or in well-ventilated area
Storage Conditions: Store in a cool, dry, and well-ventilated space, away from direct sunlight and strong oxidizers
Separation from Incompatible Materials: Keep away from acids and strong bases, avoid moisture and high temperatures
Special Provisions: Regularly inspect for damage or leaks in containers, label all containers clearly
Specific End Use(s): Follow manufacturer’s directions, use engineering controls or suitable PPE
Occupational Exposure Limits: No specific OELs for β-Mannanase, keep workplace exposure below levels that trigger respiratory symptoms in sensitized individuals
Engineering Controls: Use process enclosure, local exhaust ventilation, or other controls to keep airborne levels low
Personal Protective Equipment: Nitrile gloves, long-sleeved clothing, dust-tight safety glasses, disposable respiratory mask (N95 or P2 standard)
Special Hygiene Measures: Wash hands and face after handling, change contaminated clothing, restrict food and drinks in working areas
Environmental Exposure Controls: Implement controls to contain dust, use closed systems where feasible
Appearance: White to off-white powder or granules, fine texture
Odor: Slight fermentation-like smell
pH: Typically 4.5–7 (10% solution in water)
Solubility: Dispersible in water, insoluble in most organic solvents
Melting/Freezing Point: Not applicable (protein denatures at high temperatures rather than melting)
Boiling Point: Not applicable
Flash Point: Not determined due to non-volatile nature
Density/Bulk Density: Ranges from 0.3 to 0.7 g/cm³, depending on carrier
Explosive Properties: Fine powder can present dust explosion risk under certain conditions
Other Data: Not flammable as a bulk solid, but combustible as an airborne dust
Chemical Stability: Stable under recommended storage conditions; sensitive to heat, moisture, and acidic or basic extremes
Possibility of Hazardous Reactions: Product does not undergo hazardous polymerization, avoid mixing with strong oxidizers
Conditions to Avoid: Excessive heat, open flames, moisture, and sources of ignition
Incompatible Materials: Strong acids, alkalis, strong oxidizers
Decomposition Products: May generate small amounts of carbon monoxide, nitrogen oxides on thermal decomposition
Acute Toxicity: Not acutely toxic by ingestion, can cause mild gastric symptoms if large amounts are ingested accidentally
Skin Irritation: Mild to moderate irritation possible on repeated contact
Eye Irritation: Possible transient irritation
Respiratory Sensitization: Proteinaceous dust has a known risk of causing allergic asthma and other respiratory symptoms on repeated inhalation
Chronic Effects: Development of allergy or asthma in vulnerable individuals
Carcinogenicity/Mutagenicity: No evidence to suggest carcinogenic or mutagenic risk
Other Effects: No evidence of reproductive toxicity or specific organ toxicity
Aquatic Toxicity: Minimal risk at typical discharge levels, but large spills may cause oxygen depletion
Persistence and Degradability: Readily biodegradable by microbes in soil and water
Bioaccumulation Potential: No evidence of bioaccumulation, proteins degrade rapidly
Mobility in Soil: Moderately mobile in water, binds to soil particles and rapidly degrades
Other Adverse Effects: No evidence for toxicity to terrestrial or aquatic species at concentrations likely to be encountered
Product Disposal: Dispose of contents in accordance with local regulations; incineration or landfill permitted where allowed
Contaminated Packaging: Empty containers should be triple-rinsed, punctured, and then recycled or disposed of with standard waste
Waste Codes: Generally classified as non-hazardous waste, but check local and national rules
