Ingestion: Rinse mouth, do not induce vomiting, seek immediate medical care
Notes for Doctors: Treat symptomatically, monitor for respiratory distress, consider risk of chemical pneumonitis
Important Symptoms: Burns, irritation, pain, redness, possible blindness if eyes exposed
Suitable Extinguishing Media: Use water spray, dry chemical, foam, or carbon dioxide depending on surrounding fire
Unsuitable Media: Do not use direct streams of water on burning liquid
Hazards from Fire: May release toxic fumes such as sulfur oxides; container can rupture under intense heat
Protective Equipment: Firefighters wear full protective clothing and self-contained breathing apparatus
Special Instructions: Move containers away from fire area if safe to do so, cool fire-exposed tanks with water spray
Personal Precautions: Evacuate unnecessary personnel, ensure sufficient ventilation
Protective Equipment: Wear chemical-resistant gloves, goggles, protective suit
Environmental Precautions: Prevent entry to waterways, sewers, basements or confined areas
Spill Cleanup: Absorb spillage with inert material like dry sand, earth or vermiculite and collect in suitable container for disposal
Decontamination: Rinse spill area with plenty of water following cleanup
Safe Handling: Use only in areas with adequate ventilation, avoid breathing vapors and contact with skin, eyes, or clothing, handle with appropriate personal protective equipment
Storage Conditions: Store in tightly closed original container in a cool, dry, well-ventilated, corrosion-resistant area away from incompatible substances such as bases, oxidizers, metals
Incompatibilities: Strong bases, strong oxidizers, alkali metals, reducing agents
Special Considerations: Keep away from sources of ignition, protect from physical damage
Exposure Limits: No established occupational exposure limits for Propanesulfonic Acid (consult local regulations)
Engineering Controls: Use fume hood or local exhaust to maintain airborne levels below relevant exposure guidelines
Personal Protective Equipment: Chemical-resistant gloves, safety goggles, face shield, lab coat or apron
Respiratory Protection: Approved respirator when ventilation is inadequate
Hygiene Measures: Wash hands before breaks and after work, remove contaminated clothing and wash before reuse

Routes of Exposure: Skin and eye contact, inhalation, ingestion
Acute Effects: Corrosive, severe burns to skin and eyes, respiratory tract irritation, gastrointestinal burns if swallowed
Chronic Effects: Prolonged exposure may result in chronic skin or eye irritation
Toxicity Data: LD50 (oral, rat): Not precisely available; estimated to be moderately toxic; serious risk at high exposures
Sensitization: Not known to cause sensitization, but potential based on structure
Carcinogenicity, Mutagenicity, Reproductive Toxicity: No classification due to lack of data
Aquatic Toxicity: Harmful to aquatic organisms due to acidity, may cause long-term adverse effects
Degradability: Expected to be biodegradable; environmental persistence low with neutralization
Bioaccumulation: Not expected to bioaccumulate
Mobility in Soil: High water solubility suggests high mobility
Other Environmental Effects: Large spills can alter local pH and harm microorganisms, plants, and aquatic life
Waste Handling: Dispose of in accordance with local, regional, and national regulations as hazardous chemical waste
Methods: Neutralize with alkali (such as sodium carbonate) and dilute before disposal, collect in appropriate containers
Contaminated Packaging: Rinse thoroughly with water and dispose of according to regulations
Prevention: Do not discharge into sinks, waterways, or soil; use authorized waste management contractors
