Hazard Class: Sensitizing agent, Respiratory irritant
Label Elements: Exclamation mark symbol for warning
GHS Classification: Skin Sensitizer Category 1; Respiratory Sensitizer Category 1
Signal Word: Warning
Known Hazards: Can trigger allergic reactions via inhalation or skin contact, respiratory tract irritation, possible eye irritation
Precautionary Statements: Avoid dust formation, wear respiratory protection, prevent skin and eye contact, seek medical attention if exposed
Chemical: Trypsin
Concentration: 100% (lyophilized powder or solution)
Chemical Formula: C41H63N11O12
Molecular Weight: Approximately 23,800 Da
Impurities: May contain traces of sodium chloride or buffer components if supplied as a solution
Inhalation: Move exposed individual to fresh air, provide respiration or oxygen therapy as necessary, consult medical personnel for persistent discomfort
Eye Contact: Immediately rinse with copious amounts of clean water for at least 15 minutes, remove contact lenses, obtain medical advice if irritation persists
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing, seek medical assistance for persistent symptoms
Ingestion: Rinse mouth with water, avoid inducing vomiting, seek immediate medical advice if symptoms develop
Most Important Symptoms: Possible sneezing, coughing, skin redness, rash, allergic reactions
Extinguishing Media: Use water spray, carbon dioxide, dry chemical powder, or foam
Specific Hazards: Heating may produce irritating or toxic fumes such as carbon oxides and nitrogen oxides
Protective Equipment: Firefighters should use self-contained breathing apparatus and full protective gear
Firefighting Instructions: Move undamaged containers from fire area if safe to do so, cool containers exposed to fire with water spray
Personal Precautions: Avoid breathing dust or aerosols, use personal protective equipment, ensure proper ventilation
Environmental Precautions: Prevent release into sewers or waterways, minimize soil contamination
Containment: Carefully sweep or vacuum up spilled material, avoid dust generation, place in a closed, labeled container for disposal
Decontamination: Wipe area with damp cloth to remove residues, thoroughly ventilate area
Safe Handling: Work in a well-ventilated area, minimize dust exposure, use appropriate personal protection including gloves, lab coats, and eye/face shields
Storage Conditions: Store in tightly closed containers, keep in a cool, dry place away from incompatible materials like strong oxidizers
Incompatibilities: Avoid exposure to strong acids, bases, or oxidizing agents that may degrade enzyme activity
Special Requirements: Maintain storage temperature as recommended by supplier (commonly -20°C for lyophilized trypsin)
Workplace Exposure Limits: No strict national occupational exposure limit, but minimize exposure using good laboratory practices
Engineering Controls: Use local exhaust ventilation or biosafety cabinet to reduce airborne concentrations
Personal Protection: Wear laboratory gloves (nitrile or latex), chemical safety goggles or full-face protection, lab coat, and approved dust respirator for high concentrations
Hygiene Measures: Wash hands after handling, do not eat or drink in work areas, avoid touching face
Appearance: White or off-white powder or crystalline solid, sometimes provided as a clear solution
Odor: Odorless
pH (solution): Typically neutral to slightly alkaline (pH 7–8)
Boiling Point: Not applicable for proteins
Melting Point: Decomposes above 100°C
Solubility: Soluble in water
Stability: Stable under recommended storage conditions, sensitive to heat and denaturing chemicals
Chemical Stability: Maintains activity at low temperatures, loses function upon repeated freeze-thaw or exposure to extreme pH
Reactive Hazards: Inactive in the presence of metal ions, harsh chemicals, or strong oxidants
Decomposition Products: Thermal degradation produces CO2, NOx, and ammonia
Polymerization: Will not polymerize
Routes of Exposure: Inhalation, skin and eye contact
Acute Effects: May trigger irritation of airways or skin, possible allergic (asthmatic) reactions
Chronic Effects: Repeated or prolonged exposure can sensitize susceptible individuals, increasing allergy risks
LD50 (Oral, Rat): Data not fully established; protein enzymes generally low toxicity but high allergenicity
Carcinogenicity: Not classified as a carcinogen by ACGIH, IARC, NTP, or OSHA
Environmental Fate: Biodegradable protein, unlikely to persist in soil or water
Toxicity to Aquatic Life: Not expected to cause significant ecological harm at low concentrations, but large discharges may trigger minor oxygen demand
Bioaccumulation: Proteins degrade rapidly, no potential for accumulation
Mobility: Dissolves in surface water, disperses readily; harmless breakdown products
Waste Handling: Dispose of in accordance with local, regional, and national guidelines as non-hazardous laboratory waste
Preferred Method: Dilute remaining solutions with large amounts of water, dispose into sanitary sewer if allowed
Solid Waste: Seal in labeled container and send to authorized chemical waste facility if disposal down the drain is not permitted
Do Not: Dump concentrated enzyme directly into aquatic environments or public sewers
UN Number: Not regulated as dangerous goods under international transport guidelines
Proper Shipping Name: Not classified
Hazard Class: Non-hazardous
Packing Group: Not assigned
Transport Precautions: Protect from moisture, prevent breakage of containers, keep away from food and feedstuff cargos
Inventory Status: Listed on TSCA, EINECS, and other chemical inventories
Labeling Requirements: GHS-compliant hazard and precautionary statements as above
OSHA Status: Not classified as hazardous chemical under OSHA regulations
SARA Title III: Not subject to reporting
Other Regulations: Observe workplace health and safety regulations, apply good laboratory hygiene at all times
