Symptoms/Effects: Severe irritation, burns, difficulty breathing, coughing, nausea, headache, drowsiness; medical monitoring required for vapor exposure
Suitable Extinguishing Media: Carbon dioxide, alcohol-resistant foam, dry chemical powder
Unsuitable Extinguishing Media: Direct water spray may be ineffective
Hazards from Combustion: Toxic vapors of hydrogen chloride and phosgene can arise; danger of explosive vapor-air mixtures above 35°C
Protective Equipment for Firefighters: Self-contained breathing apparatus, full protective clothing
Advice: Evacuate area, cool exposed containers with water spray, avoid inhaling combustion products, contain run-off to prevent contamination
Personal Precautions: Evacuate unprotected personnel, ventilate area, use personal protective equipment including gloves, goggles, and respirator
Environmental Precautions: Prevent runoff into drains, surface water, or soil
Containment: Dike and absorb spill with inert material (e.g. sand, earth, vermiculite)
Cleanup Methods: Collect residues into sealable containers for proper disposal, wash contaminated area with plenty of water, ventilate area further
Special Considerations: Vapor is heavier than air, can accumulate in low areas causing explosion or health hazard
Handling: Avoid all contact with skin and eyes, minimize vapor generation, work in fume hood or well-ventilated space, keep away from ignition sources
Hygiene Practices: Wash hands and face after handling, do not eat or drink where chemical is used
Storage Conditions: Store in tightly closed containers, away from direct sunlight and incompatible materials; use a flammable cabinet approved for corrosive liquids
Incompatible Materials: Strong oxidizers, alkalis, chlorinated compounds, metals, acids
Stability Risks: Avoid storing near heat sources or in temperatures above 25°C to prevent vapor buildup
Occupational Exposure Limits: Hydrogen Chloride OSHA PEL: 5 ppm ceiling; Isopropanol OSHA PEL: 400 ppm TWA
Engineering Controls: Use chemical fume hood, local exhaust ventilation; safety shower and eyewash in work area
Personal Protective Equipment (PPE): Nitrile gloves, chemical splash goggles, lab coat, acid-resistant apron; use respirator with organic vapor acid gas cartridges for high vapor concentrations
Environmental Controls: Prevent release to environment, collect spills with care
Hygiene Measures: Remove contaminated clothing immediately, launder before reuse, wash thoroughly after exposure
Appearance: Clear, colorless to slightly yellow solution
Odor: Strong, pungent acidic and alcoholic
Odor Threshold: HCl noticeable at low ppm; Isopropanol 43 ppm

Vapor Density: >1 (heavier than air)
Solubility in Water: Complete (miscible)
Partition Coefficient (n-octanol/water): Not available for mixture
Auto-Ignition Temperature: ~425°C
Decomposition Temperature: Decomposes with toxic fume production above 350°C
Viscosity: Low, similar to water

Reactivity: Reacts vigorously with bases and strong oxidizing agents, releases heat
Conditions to Avoid: Heat, sparks, flames, direct sunlight, contact with incompatible substances
Hazardous Decomposition Products: Hydrogen chloride gas, chlorine, phosgene (in fire), carbon monoxide
Polymerization: Hazardous polymerization unlikely
Incompatible Materials: Alkalis, strong oxidizers, most metals (corrosion and hydrogen gas can form)
Likely Routes of Exposure: Inhalation, skin and eye contact, ingestion
Acute Effects: Corrosive burns to skin and eyes, irritation and damage to respiratory tract, headache, dizziness, possible flash burns
Chronic Effects: Repeated inhalation may damage respiratory tissues, chronic bronchitis, dermatitis, possible liver and kidney impacts from isopropanol

Symptoms: Cough, chest pain, vomiting, burn sensation, visual disturbance, CNS depression
Cancer/IARC Status: Not classifiable as human carcinogen; no strong evidence of mutagenicity or carcinogenicity in humans; exposure risks are acute and chemical burns
Ecotoxicity: Hydrogen chloride and isopropanol both demonstrate high acute toxicity to aquatic organisms, even in small quantities; disrupts pH and oxygen transfer
Persistence and Degradability: Isopropanol degrades biologically and photochemically in environment, hydrogen chloride dissociates to ions in water
Bioaccumulative Potential: Low for both substances
