Inhalation: Move affected person into fresh air. Seek medical attention if symptoms persist.
Skin Contact: Wash area thoroughly with soap and plenty of water. Remove contaminated clothing.
Eye Contact: Rinse eyes gently with running water for at least 15 minutes. Contact a doctor if irritation continues.
Ingestion: Rinse mouth with water and drink water. Do not induce vomiting unless advised by medical personnel. Seek attention if discomfort continues.
Suitable Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or foam.
Unsuitable Media: None known based on current ingredient profile.
Fire Hazards: Product may burn if strongly heated or involved in a larger fire.
Combustion Products: Carbon oxides and other unknown organic compounds can release during fire.
Special Equipment: Firefighters should wear full protective gear and self-contained breathing apparatus.
Other Considerations: Cool containers exposed to heat with water spray to prevent pressure build-up.
Spill Response: Collect dry powder with clean, non-sparking tools and place in a labeled waste container.
Personal Precautions: Use adequate ventilation, avoid breathing dust, wear protective gear including gloves and safety goggles.
Environmental Precautions: Prevent large amounts from entering drains, surface water, or soil.
Cleanup Methods: Vacuum or sweep up spilled material, minimize dust generation, clean with water and dry thoroughly.
Handling: Avoid dust generation and direct contact with eyes or skin, handle with proper protective equipment.
Hygiene: Wash hands after dealing with the powder, do not eat, drink, or smoke in handling areas.
Storage Conditions: Store in a cool, dry, well-ventilated place, keep containers tightly closed when not in use.
Incompatibles: Keep away from strong oxidizing agents, moisture can clump the powder and impact quality.
Packaging Materials: Use original or compatible sealed containers.
Engineering Controls: Use proper exhaust ventilation to minimize dust in the working area.
Exposure Limits: No established exposure limits for peptone, but control dust as for nuisance particulates (OSHA TWA 15 mg/m3 for total dust).
Personal Protective Equipment: Use safety goggles, dust masks or respirators (NIOSH-approved), and gloves.
General Protection: Wear lab coats or suitable clothing, keep work area clean, avoid direct contact.
