Eye Contact: Rinse eyes gently with cool water for at least 15 minutes, lift eyelids to ensure thorough washing, seek immediate medical attention for pain or vision changes
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and plenty of water, if irritation persists see a doctor
Inhalation: Move to fresh air promptly, keep comfortable, provide oxygen if breathing difficulty develops, call a medical professional if symptoms don’t improve
Ingestion: Rinse mouth, do not induce vomiting unless told by a doctor, never give anything by mouth to someone unconscious, call poison center or physician immediately
Suitable Extinguishing Media: Use dry chemical powder, foam, carbon dioxide, or alcohol-resistant foam
Unsuitable Extinguishing Media: Avoid water jets or high-pressure streams directly on fire
Hazards from Fire: Vapors may form explosive mixtures with air, combustion creates nitrogen oxides, carbon oxides, and toxic fumes
Protective Equipment: Firefighters wear self-contained breathing apparatus, flame-retardant clothing, gloves and boots
Special Procedures: Cool exposed containers using water spray, prevent runoff from contaminating water sources
Personal Precautions: Ventilate area, stop leak if safe, avoid breathing vapors, wear protective gloves, goggles, and mask
Environmental Precautions: Prevent further leakage or spillage, avoid contamination of soil, drains, or watercourses
Cleanup Methods: Absorb with inert material like earth or sand, place in properly labeled containers, ventilate area after cleanup, wash area with detergent and water, dispose of according to regulations
Handling: Wear suitable protective clothing, keep away from open flames and sparks, avoid skin/eye contact, use in a fume hood or ventilated area, do not eat, drink or smoke near product
Storage: Store in cool, dry, well-ventilated place, keep tightly sealed in original container, store away from oxidizers, acids, ignition sources, segregate from food or incompatible materials
Specific Uses: Follow instructions for laboratory or industrial processes, do not transfer to unmarked containers
Occupational Limits: Not established for 3,5-Dimethylpiperidine, use in accordance with available workplace exposure guidelines for similar organic amines
Engineering Controls: Use exhaust ventilation, fume hoods, splash guards
Personal Protective Equipment: Chemical-resistant gloves (nitrile, neoprene), safety goggles, face shield, flame-resistant lab coat, closed footwear
Respiratory Protection: If airborne levels exceed safe limits, use approved respirator
Hygiene Measures: Wash hands after handling, remove contaminated clothing, launder before reuse
