Inhalation: Move affected person to fresh air; seek medical advice if coughing, shortness of breath or respiratory distress occur
Ingestion: Rinse mouth, drink water; not expected to be hazardous in typical amounts but consult physician if gastrointestinal symptoms develop
Skin Contact: Wash thoroughly with soap and water; remove contaminated clothing; apply moisturizer if redness or irritation appears
Eye Contact: Rinse cautiously with water for several minutes; remove contact lenses; seek healthcare if irritation persists
Advice for Medical Personnel: Treat symptomatically; show SDS for bacterial nature of exposure
Symptoms/Effects: Respiratory allergy in sensitized persons, conjunctival redness, mild skin response possible
Suitable Extinguishing Media: Water spray, foam, dry chemical or carbon dioxide
Unsuitable Extinguishing Media: No known incompatibility with standard extinguishing agents
Hazards from Product: Product itself is non-flammable; excipient materials such as sugars or powdered milk could combust in rare fire
Protective Equipment: Firefighters need standard PPE including respiratory protection when responding to facility fires
Decomposition Products: Combustion of packaging or sugars may release smoke, carbon oxides
Firefighting Guidance: Remove product containers from fire area if safe; avoid direct contact with dust or smoke
Personal Precautions: Wear gloves, lab coat, eye protection, dust mask or respirator for spills or powder handling
Environmental Precautions: Prevent runoff into water systems; contain large spill with absorbent material
Methods for Clean-Up: Sweep or vacuum gently to minimize dust; dampen with water if needed; dispose as per section on disposal
Handling Precautions: Restrict access to area until cleaning is complete; avoid aerosol generation
Decontamination: Wash surface with detergent and water after material pick-up; disinfect with standard laboratory disinfectant
Safe Handling: Use in well-ventilated area; avoid inhaling dust or aerosols; wear protective clothing for repeated tasks
Hygiene Measures: Wash hands and exposed skin after handling; avoid eating or drinking in work area
Storage Conditions: Store in cool, dry environment; refrigeration required for live cultures, freezing for long-term stability
Incompatibilities: Strong acid or base, high temperature, or desiccation may reduce viability
Storage Packaging: Sealed, clearly labeled containers to prevent contamination or moisture ingress
Special Requirements: Biohazard signage only if local policies classify live cultures as such; secure storage away from incompatible chemicals
Occupational Exposure Limits: Not established; control airborne levels with engineering measures
Engineering Controls: Biological safety cabinet or local exhaust ventilation for large-scale use or airborne material
Respiratory Protection: Dust mask or approved particulate respirator to reduce inhalation risk during handling or spill
Skin Protection: Laboratory gloves resistant to moisture and biological agents
Eye Protection: Safety goggles or face shield when handling powders or large liquid volumes
Other Protective Measures: Lab coat, full-length pants, closed footwear; remove and decontaminate clothing after contact
Form: Lyophilized powder, slurry, or suspension in liquid medium
Color: White to pale tan

Boiling/Melting Point: Not applicable to live cultures
Flash Point: Not applicable; excipients like lactose or sugars may have high flash points in powdered form
Solubility: Dispersible in water, insoluble in oils or alcohols
Density: Depends on excipients, typically around 0.3–0.5 g/cm³ for dry preparations
Stability: Stable in dry, cool, low-light conditions
Particle Size: Finer than 200 μm for powders
Chemical Stability: Maintains viability in recommended storage; loss of activity from high temperatures or humidity
Reactivity: Biologically active; not chemically reactive with typical laboratory chemicals
Hazardous Reactions: None known with standard laboratory/culture materials
Materials to Avoid: Strong oxidizers or acids degrade cell viability
Decomposition Products: Lactic acid and mild volatile organic compounds as byproducts in wet storage
Hazardous Polymerization: Not known to occur
Acute Toxicity: Non-toxic to humans in handling concentrations
Chronic Exposure: No reports on chronic toxicity; extended exposure may cause mild allergies
Routes of Exposure: Inhalation, ingestion, skin and eye contact
Potential Health Effects: Very low; minor gastrointestinal effects in rare ingestion cases by immunocompromised individuals; conjunctival irritation
Carcinogenicity: Not listed by IARC, NTP, OSHA as carcinogen
Mutagenicity: No evidence present; used extensively in food fermentation for over a century
Sensitization: Low risk; possibility exists for laboratory staff with repeated exposure
Medical Conditions Aggravated: Asthma, severe immunodeficiency could increase risk from bioaerosols
Ecotoxicity: No evidence of harm to aquatic or terrestrial environments
Persistence and Degradability: Natural microorganism, rapidly inactivated by sunlight, temperature, desiccation
Bioaccumulation: Unlikely, organism does not persist outside specialized environments
