Product Name: Culture Media for Microorganism Growth
Common Names: Nutrient Agar, Sabouraud Dextrose Agar, MacConkey Agar, Blood Agar, Tryptic Soy Broth, Mueller Hinton Agar
Recommended Uses: Cultivation, isolation, and maintenance of microbial cultures in laboratories
Supplier Information: Laboratory reagents manufacturer, address and phone number found on product packaging
Emergency Contact: Call local poison control center or emergency medical services
GHS Classification: Not classified as hazardous under GHS for most standard culture media
Physical Hazards: Dust may cause respiratory irritation during handling; can create slipping hazard if spilled
Health Hazards: Inhalation of powder or prolonged skin contact can cause mild irritation; eye contact may cause discomfort
Environmental Hazards: Accidental release in large quantities may lead to eutrophication in water systems
Main Risks: After inoculation with pathogens, cultures become biohazardous; treat any used media as potentially infectious
Principal Components: Enzymatic digest of casein, beef extract, yeast extract, sodium chloride, agar, glucose, peptone
Chemical Ranges: Typical concentrations found in lab-prepared media; varies across specific formulas
Additives: Selective agents, pH indicators, colorants, depending on the type of medium
CAS Numbers: No single CAS number for complete medium; individual components include agar (9002-18-0), sodium chloride (7647-14-5)
Inhalation: Move affected person to fresh air, rinse mouth, monitor respiratory symptoms
Eye Contact: Rinse cautiously with water for at least 15 minutes; remove contact lenses
Skin Contact: Remove contaminated clothing, wash exposed skin with soap and water
Ingestion: Rinse mouth with water and drink water if conscious; seek medical attention if feeling unwell
Further Action: Seek medical advice in cases of persistent symptoms; note any known allergies
Suitable Extinguishing Media: Use water spray, CO₂, dry chemical, or foam
Specific Hazards: Combustion may produce carbon oxides and nitrogen oxides
Protective Equipment: Firefighters require self-contained breathing apparatus and protective clothing
Additional Advice: Avoid inhaling dust or smoke; evacuate area if fire becomes large or uncontrolled
Personal Precautions: Use protective gloves and mask during cleanup to avoid inhalation and contact
Spill Response: Sweep up spilled powder or collect agar solid with a scoop; avoid creating dust
Environmental Measures: Prevent bulk material from entering drains or watercourses
Decontamination: Wash spill site with water and detergent after cleanup
Safe Handling: Keep containers tightly sealed; use in well-ventilated areas; avoid dust formation
Hygienic Practices: Wash hands thoroughly after use, especially before eating or drinking
Storage Conditions: Store in cool, dry, ventilated place; avoid moisture, heat sources, and direct sunlight
Incompatibilities: Keep away from oxidizing agents and strong acids
Shelf Life: Most dehydrated media remain stable for at least 2 years if properly stored
Exposure Limits: No established occupational exposure limits for complete media
Engineering Controls: Laboratory ventilation and, if possible, local exhaust for bulk powder handling
Personal Protection: Lab coat, protective gloves, safety goggles or face shield when preparing media
Respiratory Protection: Use dust mask if handling large quantities in powder form
Other Controls: Eye wash stations and emergency showers available in laboratory
Appearance: Fine powder (dehydrated); solid or gel (prepared agar); clear to slightly turbid in solution
Color: Cream, off-white to pale yellow, sometimes reddish or green depending on additives
Odor: Mild, characteristic organic odor
pH (at 25°C): Typically ranges from 6.5 to 7.4
Melting Point: Agar melts at approximately 85°C, solidifies at 37–42°C
Solubility: Readily dispersible in water, forms a gel upon cooling
Vapor Pressure: Not applicable for solid or gel form
Flammability: Not flammable in solid or gel state; powder can combust if exposed to open flame
Chemical Stability: Stable under recommended storage and handling conditions
Conditions to Avoid: Exposure to moisture, extreme heat, and strong oxidizers
Incompatible Materials: Strong acids, bases, oxidizers
Hazardous Decomposition: Thermal decomposition may release carbon oxides and nitrogen oxides
Reactivity: Not reactive in normal laboratory settings
Acute Toxicity: Low toxicity for standard dehydrated and rehydrated media components
Inhalation Effects: Temporary respiratory irritation possible with dust exposure
Dermal and Eye Effects: Mild and reversible irritation on contact
Chronic Effects: No known long-term health effects from handling uninoculated medium
Special Risks: Inoculated media may pose infectious hazard depending on cultured organism
Environmental Fate: Components break down naturally; bioaccumulation unlikely
Biohazard Concerns: Used media can harbor pathogenic microbes posing ecological risk if released untreated
Persistence: Organic elements degrade over time; agar and proteins consumed by environmental microbes
Aquatic Toxicity: Large spills may cause nutrient enrichment in water, impacting aquatic life
Waste Disposal: Dispose of solid medium and liquid waste as laboratory biohazard following institutional protocol
Contaminated Packaging: Incinerate or autoclave contaminated containers before disposal
Environmental Impact: Do not discharge large quantities into water bodies, sewer, or soil
Local Guidelines: Follow local, national, and institutional rules for infectious waste handling
UN Number: Not regulated for transport unless contaminated with pathogens
Transport Class: Not classified as dangerous for road, rail, sea, or air transport in dehydrated or prepared uninoculated form
Packing Instructions: Seal in sturdy, moisture-resistant containers; mark if biohazard present after use
Special Precautions: For inoculated cultures, use triple containment and label as infectious substance
Chemical Regulations: Ingredients found on common chemical inventories (TSCA, EINECS, etc.)
Biohazard Regulations: All used media contaminated with microorganisms require adherence to biosafety level requirements
Labeling Requirements: Clearly label all containers with product name, hazard warnings, and expiry date
Workplace Safety: Comply with relevant occupational health and safety laws regarding lab chemical use
Other Requirements: Observe institutional policies and governmental regulations for chemical and biological agents
