Ingestion: Rinse mouth thoroughly with water; do not induce vomiting; seek immediate medical attention
Notes for Physician: May cause severe mucosal injury; treat symptomatically; monitor for respiratory, gastrointestinal, and dermal complications
Suitable Extinguishing Media: Dry chemical, foam, or carbon dioxide; avoid water as run-off may be corrosive or toxic
Unsuitable Extinguishing Media: Direct water jets increase runoff risk
Specific Hazards: Toxic gases including sulfur oxides, fluorinated compounds, and nitrogen oxides released by thermal decomposition
Protective Equipment for Firefighters: Full-body suit, positive pressure self-contained breathing apparatus, chemical-resistant boots and gloves
Advice: Isolate area, approach upwind, use non-sparking tools, cool unopened containers with spray if safe
Personal Precautions: Wear full protective suit, gloves, face protection, breathing apparatus in case of heavy exposure
Environmental Precautions: Prevent spillage from entering drains, surface water, or soil; use barriers for containment
Methods for Cleanup: Absorb spillage with inert material such as sand or earth; place in corrosion-resistant container; ventilate area; wash spill site after material pickup
Decontamination: Use alkaline solution for residual acid neutralization; wash down with large quantities of water, controlling run-off
Safe Handling: Use only in well-ventilated areas; keep away from heat, sparks, open flame; avoid inhalation, ingestion, and contact with skin or eyes; keep containers tightly closed
Storage Conditions: Store in corrosion-resistant containers with tight-fitting lids; keep in cool, dry, well-ventilated space; segregate from strong bases, oxidizers, reducing agents, metals, and foodstuffs
Transfer Recommendations: Use dedicated lines and equipment; regularly inspect for corrosion or leakage
Incompatible Materials: Avoid storage near alkali metals, cyanides, chlorinated solvents, strong oxidizers, and reducing agents
Occupational Exposure Limits: Methanesulfonic acid: TLV not established; use limits for strong acids as guidance
Engineering Controls: Chemical fume hood or local extraction ventilation; non-sparking, corrosion-resistant equipment
Personal Protective Equipment: Impermeable gloves (butyl rubber or neoprene), chemical goggles with face shield, acid-resistant lab coat, long pants, closed shoes
Respiratory Protection: Air-purifying respirator with acid gas filter for low exposure, self-contained breathing apparatus for high concentration

Chemical Stability: Stable under recommended handling and storage conditions
Reactivity: Vigorous reaction with bases, water, or oxidizers possible, producing heat or hazardous vapors
Hazardous Reactions: Exothermic reactions with alkali metals, cyanides, chlorinated compounds
Hazardous Decomposition Products: Toxic gases such as hydrogen sulfide, sulfur dioxide, nitrogen oxides, hydrofluoric acid
Conditions to Avoid: Heat, open flame, direct sunlight, moisture, incompatible substances
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Toxicity: Oral LD50 (rat) for methanesulfonic acid: around 1600 mg/kg; inhalation exposure can cause lung damage
Corrosivity: Severe skin and eye damage with direct exposure
Chronic Effects: Prolonged exposure may lead to dermatitis, respiratory sensitization, or mucosal injuries
Carcinogenicity: Not listed as carcinogen by IARC, NTP, or OSHA; seek updated studies for complex mixtures
Mutagenicity: Data unavailable; recommend precautionary approach
Other Effects: Risk of delayed pulmonary edema from inhalation; potential CNS depression upon overexposure
Aquatic Toxicity: Very toxic to aquatic organisms; fish and invertebrates highly sensitive to low concentrations
Persistence and Degradability: Methanesulfonic acid expected to be readily biodegradable; fluorinated components may bioaccumulate or persist
Bioaccumulation Potential: Fluorinated thioamides have potential for bioaccumulation in aquatic systems
Mobility in Soil: Acid readily mobile, especially with water; fluorinated portions may display lower mobility
Other Adverse Effects: Potential for long-term effects in aquatic environments; may lower pH of water bodies causing indirect ecosystem impacts
