Inhalation: Move affected person to fresh air; monitor for persistent irritation, cough, or shortness of breath
Skin Contact: Rinse affected area with plenty of water and gentle soap; remove contaminated clothing
Eye Contact: Flush eyes with plenty of water for several minutes; seek medical advice if irritation persists
Ingestion: Rinse mouth thoroughly; drink water if discomfort occurs, seek medical attention if gastrointestinal symptoms appear
Medical Attention: Call a physician if allergic reaction or persistent irritation is noted; provide product information to health professionals
Suitable Extinguishing Media: Water spray, dry chemical, foam, or carbon dioxide
Unsuitable Media: None known for this biological product
Specific Hazards: Product is non-flammable, but carriers may release combustible dust in case of excessive dispersion
Protective Equipment for Firefighters: Wear full protective gear and self-contained breathing apparatus in confined spaces
Combustion Products: May emit carbon dioxide, carbon monoxide, and other typical decomposition products of organic matter
Personal Precautions: Use N95 or higher particulate respirator to avoid inhaling fine powder
Environmental Precautions: Avoid entry into watercourses in large amounts, as it may impact natural microbial balances
Methods for Clean Up: Sweep up powder carefully; avoid creating dust clouds, collect into suitable containers for disposal
Small Release Response: Dampen spilled material, wipe surfaces, and use proper ventilation; wash area with soapy water
Disposal: Dispose of sweepings according to local and national regulations for non-hazardous organic waste
Handling Precautions: Open containers in well-ventilated areas; minimize airborne dust by slow and controlled pouring
Safe Handling Advice: Use personal protective equipment like gloves and dust mask especially in bulk applications
Storage Conditions: Store at 2–8°C, protected from heat, moisture, and direct sunlight
Packaging: Keep in original, tightly closed containers with product identification clearly labeled
Special Instructions: Avoid repeated freeze-thaw cycles; do not return unused material to original container
Incompatibilities: Strong oxidants, disinfectants; may reduce viability
Occupational Exposure Limits: No specific OEL established; total dust exposure limits may apply (e.g., OSHA PEL Total Dust: 15 mg/m³)
Engineering Controls: Local exhaust or HEPA-filtered ventilation where handling in bulk
Personal Protective Equipment: Safety goggles, laboratory gloves, lab coat, N95 or higher respirator during manipulation of powdered forms
Hygiene Measures: Wash hands after use, do not eat, drink, or smoke when handling cultures
Environmental Exposure Controls: Prevent release of large amounts to soil or water due to long-term ecological effects
Physical State: Powder, lyophilized cakes, or granules depending on product form

Conditions to Avoid: Excessive moisture, direct heat, repeated temperature fluctuations
Materials to Avoid: Strong acids, bases, oxidizing agents
Decomposition Products: Typical organic decomposition products such as carbon dioxide, water, trace VOCs under fire
Acute Toxicity: No data indicating oral, dermal, or inhalation toxicity in humans at typical exposure levels
Skin Irritation: Minimal or no irritation, based on industrial and consumer handling
Eye Irritation: Mild transient irritation possible from dust
Sensitization: Extremely rare allergic reactions; people with milk protein allergies may react if carrier is present
Chronic Effects: No evidence of long-term health risks in routine use
Special Risk Groups: Those with severe immunodeficiency should avoid exposure to concentrated culture
Mutagenicity/Carcinogenicity: No evidence based on published safety data and regulatory reviews
Persistence: Non-persistent under aerobic conditions; probiotic microbes degrade naturally
Bioaccumulation: No evidence for accumulation in terrestrial or aquatic food chains
Toxicity to Aquatic Life: No adverse effects at typical release levels
Mobility: Cells may disperse in water but will not persist due to rapid die-off in non-target environments
Effects on Soil: High doses may alter native microbial populations
