Inhalation: Remove person to fresh air and keep at rest. If symptoms persist, seek medical attention.
Skin Contact: Flush exposed area with soap and plenty of water for at least 15 minutes. Remove contaminated clothing.
Eye Contact: Rinse with plenty of water for several minutes. Remove contact lenses if present and easy to do; continue rinsing.
Ingestion: Rinse mouth with plenty of water. Never give anything by mouth to an unconscious person and get medical help.
Most Important Symptoms and Effects: Irritation of skin and eyes, respiratory discomfort, abdominal pain, headache, nausea.
Notes for Physicians: Treat symptoms, ensure patient has open airway, provide oxygen if breathing is difficult.
Suitable Extinguishing Media: Use foam, carbon dioxide, dry chemical powder, or water spray.
Specific Hazards Arising from Chemical: Vapors may form explosive mixtures with air. Fire may produce toxic fumes including carbon monoxide, nitrogen oxides.
Special Protective Equipment: Wear self-contained breathing apparatus and full protective clothing.
Advice for Firefighters: Approach fire upwind. Avoid inhaling smoke and vapors. Cool surrounding containers with water spray to prevent explosion. Dispose contaminated firefighting water in accordance with regulations.
Flash Point: Approximately 70°C (158°F)
Personal Precautions: Avoid contact with skin, eyes, and clothing. Evacuate area. Wear suitable chemical-resistant gloves, goggles, and protective clothing.
Environmental Precautions: Prevent material from entering drains, surface water, or soil. Notify authorities if spill contaminates environment.
Cleanup Methods: Absorb spill with inert material (sand, earth, vermiculite), collect in a suitable container for disposal. Ventilate the area and wash spill site after material pickup is complete.
Decontamination: Dispose cleaning materials as hazardous waste, keep in well-ventilated place.
Risk of Vapors: Provide adequate ventilation to reduce vapor build-up.
Handling: Avoid inhalation, ingestion, or skin contact. Wash thoroughly after handling. Use only in well-ventilated areas. No open flames, spark sources, or smoking.
Storage Conditions: Store in a cool, dry, well-ventilated area. Keep container tightly closed and away from heat, direct sunlight, acids, and oxidizers.
Incompatibilities: Strong oxidizing agents, reducing agents, acids, and alkalis.
Packaging Materials: Use corrosion-resistant containers, properly labeled.
Exposure Limits: No available occupational exposure limits established specifically for 2-Formylpyrrole.
Engineering Controls: Use local exhaust and general ventilation to maintain airborne concentration below recommended limits. Emergency eye wash stations and safety showers are recommended.
Respiratory Protection: Use a NIOSH-approved organic vapor respirator in case of insufficient ventilation.
Skin Protection: Wear chemical-resistant gloves (nitrile or neoprene), long-sleeved clothing, and lab coat.
Eye Protection: Chemical safety goggles or face shield.
Hygiene Practices: Do not eat, drink, or smoke during use. Remove contaminated clothing before entering eating areas. Wash hands thoroughly after handling.

Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Effects: Causes skin and eye irritation, respiratory tract irritation, can be harmful if swallowed or inhaled.
Chronic Effects: Prolonged or repeated exposure may cause dermatitis, sensitization, or other health effects yet inadequately studied in humans.
Toxicity Data: Limited animal data; oral LD50 (rat) not precisely determined due to scarcity of studies in literature.
Symptoms of Overexposure: Headache, dizziness, nausea, abdominal pain, skin redness or rash, eye redness.
Carcinogenicity: No components identified as probable or confirmed human carcinogen by IARC, NTP, or OSHA.
Mutagenicity: Data sparse; no strong evidence found.
Teratogenicity: Not clearly established in animal models.
Target Organs: Skin, eyes, respiratory system, possibly liver with large exposures.
Ecotoxicity: No reliable long-term data, but similar compounds show moderate toxicity to aquatic organisms.
Persistence and Degradability: Likely to undergo biodegradation under aerobic conditions; slow in anaerobic environments.
Bioaccumulative Potential: Partition coefficient suggests moderate bioaccumulation risk, though lack of data for precise estimate.
Mobility in Soil: Some mobility expected due to partial water solubility.
Other Adverse Effects: Avoid release into waterways, drains, or environment; may impact aquatic life and microorganisms in large quantities.
Disposal Methods: Material and containers should be collected and disposed of as hazardous waste through licensed waste disposal contractors. Incineration preferred, following national and local environmental regulations.
