Pictograms: Corrosion, Exclamation mark
Precautionary Statements: Wear protective gear; wash face, hands thoroughly after handling; do not breathe mist or vapors; keep away from incompatible materials
Chemical Name: Hydrochloric Acid
Concentration: 20–38% w/w in commercial grades, balance is water
Impurities: Trace metals and other minor acids depending on process; not always present
CAS Number (HCl): 7647-01-0
Inhalation: Move person to fresh air immediately; provide oxygen if breathing is labored; seek medical help for persistent cough or chest pain
Skin Contact: Remove contaminated clothing; flush skin with copious amounts of water; continue rinsing for at least 15 minutes; medical attention needed for burns or persistent irritation
Eye Contact: Remove contact lenses; rinse eyes continuously with water for at least 15 minutes, lifting upper and lower lids occasionally; immediate medical attention required
Ingestion: Do not induce vomiting; rinse mouth with water; provide water or milk if alert; never give anything by mouth to an unconscious person; seek emergency medical help
Delayed Symptoms: Potential for damage to mucous membranes, skin or respiratory system with delayed complications possible
Flammability: Hydrochloric acid does not ignite
Appropriate Extinguishing Media: Water spray, dry chemical, carbon dioxide, or appropriate foam for surrounding fire; avoid direct stream on acid to minimize spattering
Fire Hazards: At high temperatures, hydrogen chloride gas can form; intense heat may cause containers to rupture
Protective Equipment: Firefighters use chemical splash suits and self-contained breathing apparatus; keep upwind of fire
Combustion Products: Hydrogen chloride gas, chlorine gas under certain extreme conditions; both are highly irritating, toxic
Personal Precautions: Evacuate area if needed; wear acid-resistant gloves, chemical splash goggles, face protection, full protective clothing, and respiratory protection for mist or gas exposure
Environmental Precautions: Prevent spillage from entering drains, sewers, or surface waters; dike area with sand or other non-combustible absorbent
Methods for Cleaning Up: Neutralize spill with soda ash (sodium carbonate) or lime; collect residue for disposal; ventilate area; wash affected surfaces with water after neutralization
Reporting: Notify authorities for significant releases according to local environmental regulations
Safe Handling: Use in well-ventilated areas; avoid inhaling vapors; use non-sparking, corrosion-resistant tools; ensure containers are tightly closed; handle only with proper training
Storage Conditions: Store in cool, dry, well-ventilated area far from direct sunlight, heat sources, and incompatible substances; use only containers designed for hydrochloric acid
Incompatibility: Avoid organic materials, strong oxidizers, bases, metals (especially reactive/reactive metals like sodium, potassium, or aluminum), cyanides, sulfides, some plastics
Other Precautions: Keep separated from food, feed, and incompatible chemicals; periodic inspection of storage area and containers advised
Occupational Exposure Limit: OSHA PEL: 5 ppm Ceiling; ACGIH TLV: 2 ppm Ceiling
Engineering Controls: Use chemical fume hoods, acid-resistant local exhaust ventilation systems; emergency shower and eyewash station accessible nearby
Personal Protective Equipment: Chemical splash goggles, face shield, acid-resistant gloves (PVC, neoprene, butyl rubber), full-body chemical-resistant apron or suit, boots; use NIOSH-approved respirator if exposure limits are exceeded or in low ventilation
Hygiene Measures: Do not eat, drink, or smoke while using this product; wash hands and face before breaks and after handling
Appearance: Clear, colorless to slightly yellow liquid
Odor: Acidic, pungent, sharp
pH: Highly acidic (typically <1 for concentrated solutions)
Boiling Point: 110°C (conc. solution, can vary with %)
Melting Point: -27°C (conc. solution)
Vapor Pressure: 40 mm Hg at 20°C
Vapor Density: 1.3 (air = 1)
Solubility in Water: Completely miscible
Specific Gravity: 1.18–1.20 (depends on strength)
Evaporation Rate: Not readily measured, rapid for concentrated solutions
Chemical Stability: Stable under normal conditions if kept sealed
Decomposition Products: Hydrogen chloride gas
Incompatible Materials: Bases, oxidizers, reducing agents, reactive metals, organic compounds; mixing can generate heat, toxic gases
Hazardous Reactions: Reacts violently with strong alkalis and oxidizers; emits hydrogen chloride gas on contact with water or heat
Routes of Exposure: Inhalation, skin contact, ingestion, eye contact
Acute Effects: Corrosive to skin, eyes, mucous membranes; severe burns possible; inhalation may cause cough, hoarseness, inflammation and edema of larynx and bronchi, chemical pneumonitis
Chronic Effects: Prolonged inhalation may cause tooth erosion, chronic bronchitis; repeated skin exposure can cause dermatitis
LD50 (oral, rat): 900 mg/kg (for concentrated solutions)
Symptoms: Burning of eyes, nose, throat; coughing, choking, nausea, vomiting, abdominal pain, chest tightness
Aquatic Toxicity: Harmful to aquatic organisms; rapid acidification of water bodies can be fatal to fish and invertebrates
Soil Impact: Low pH alters soil microflora and may limit plant growth
Bioaccumulation: Not considered bioaccumulative
Persistence and Degradability: Dissociates into hydrogen and chloride ions, which persist but do not bioaccumulate
Water Contamination Risks: Acid release leads to dangerous pH shifts in streams and lakes; municipal and industrial water treatment required for spills or wastewater
Waste Treatment: Neutralize with lime or sodium carbonate until slightly alkaline; confirm pH before disposal
Method: Dispose in accordance with all local, regional, national, and international regulations; never pour undiluted acid down drains or into water bodies
Container Disposal: Triple rinse with water and treat rinseate as hazardous waste; do not reuse for food or drink storage
Regulatory Waste Class: Classified as hazardous waste under RCRA (U.S.) and many international regulatory frameworks
UN Number: UN1789
