Chemical Name: Pancreatic Elastase Type I, sourced from porcine pancreas
Chemical Formula: Protein enzyme, not a simple chemical compound, falls under serine protease class
Common Uses: Laboratory research, protein digestion, cell biology, and molecular studies
Physical Description: Typically appears as a lyophilized powder or crystalline substance, sometimes off-white or pale yellow
Odor: Usually no significant odor detectable
Industries Using Product: Biotech, pharmaceutical research, academic laboratories, diagnostics
Globally Harmonized System (GHS) Classification: Not listed as a hazardous substance for most laboratory uses, but exposure may cause respiratory sensitization or allergic reactions
Symptoms of Exposure: Sneezing, coughing, possible shortness of breath, rare cases of skin or eye irritation
Warning Symbols: Irritant, although many labs do not require hazard pictograms for non-dust-form activities
Target Organs: Respiratory tract, mucous membranes
Routes of Entry: Inhalation, skin and eye contact exceed food-related exposure risks
Long-term Risks: Sensitization in some individuals over repeated exposure
Active Ingredient: Pancreatic elastase Type I, purified from porcine pancreas
Concentration: Purity often exceeds 90% for lab-grade product
Other Components: Low levels of buffer salts or stabilizers, depending on supplier, but primary constituent is the enzyme
Allergen Potential: Animal-derived ingredient introduces risk for people with sensitivities to animal proteins
Inhalation: Remove exposed person to fresh air, encourage gentle breathing, medical attention required if symptoms linger
Skin Contact: Wash area thoroughly with water and mild soap, remove contaminated clothing, ongoing irritation warrants medical review
Eye Contact: Rinse immediately with clean water for at least 15 minutes, blink often, medical help recommended for persistent discomfort
Ingestion: Rinse mouth, do not attempt to induce vomiting, seek medical evaluation for moderate to severe symptoms
General Advice: Always report exposures in occupational health records, especially if symptoms persist after initial response
Suitable Extinguishing Agents: Water spray, carbon dioxide, dry powder, foam—choose method based on materials nearby
Hazardous Combustion Products: Burning can yield carbon monoxide, carbon dioxide, nitrogen oxides
Special Firefighting Procedures: Wear self-contained breathing apparatus, avoid inhaling smoke or protein dust
Fire/Explosion Risks: Low flammability as an isolated enzyme, moderate concern if dispersed in air as fine powder
Additionals: Remove containers from exposure if possible and safe, cool with water
Personal Protection: Gloves, dust mask or respirator, goggles
Containment: Avoid generating dust, cover spill with damp disposable towels
Clean-up Procedures: Scoop up solids, wipe surfaces with wet material—do not use dry sweeping
Environmental Cautions: Prevent runoff into drains, protein content could disrupt aquatic systems
Waste Disposal: Place waste into sealed containers, label with biohazard warning if local policy requires
Safe Handling Procedures: Work in well-ventilated area, avoid inhaling dust, wear lab protective clothing
Avoidance: Prevent formation of aerosols or mists during weighing or transfer
Storage Conditions: Store in tightly closed bottles at specified low temperature (usually recommended 2-8°C, some forms benefit from -20°C for long-term), avoid humidity
Incompatible Materials: Strong oxidizers, acids, bases can degrade enzyme function
Labeling: Clear labeling, including animal-origin warning, assists in safe workplace practices
Ventilation: Local exhaust or fume hood recommended especially for weighing or transfer
Personal Protective Equipment: Laboratory gloves (nitrile or latex), lab coat, safety glasses or chemical splash goggles
Respiratory Protection: Dust masks (N95 or equivalent) if manipulating large quantities or if ventilation is poor
Engineering Controls: Closed systems or biosafety cabinet reduces airborne dust
Hygiene Practices: Wash hands and forearms after handling, avoid touching face or exposed skin
Appearance: White to pale yellow powder, crystalline or lyophilized solid
Solubility: Soluble in water, buffer solutions
pH Range: Displays enzymatic activity at near-neutral to slightly alkaline range
Melting Point: Not well-defined; protein denaturation occurs instead of melting
Odor Threshold: No notable detectable odor
Decomposition: Above 50°C or outside neutral pH, rapid loss of enzymatic activity
Chemical Stability: Remains stable in dry form, loses activity exposed to heat, humidity, repeated freeze-thaw cycles
Conditions to Avoid: High temperature, light, acids, strong bases
Hazardous Decomposition: Burning generates toxic fumes such as nitrogen oxides and carbon monoxide
Materials to Avoid: Strong oxidizers, incompatible with strong bleaching agents
Polymerization: Product not known to polymerize
Acute Toxicity: Oral or dermal toxicity data for pure enzyme is limited
Skin/Eye Effects: Mild irritant in some sensitive individuals, rarely causes dermatitis
Respiratory Sensitization: Laboratory workers report allergic symptoms after repeated exposure
Chronic Effects: Not widely studied, risk of occupational asthma for sensitized personnel
Carcinogenicity: Not classified as carcinogenic by major regulatory bodies
Aquatic Toxicity: No large-scale studies, but as a protein, elastase may increase oxygen demand in waterways
Persistence/Degradability: Biodegradable, unlikely to persist long in typical environments
Bioaccumulation: Not expected, most proteins quickly degrade in soil and water
Environmental Impact: Release in high quantities can cause imbalance in small water systems, proper disposal remains better than dilution
Recommendations: Avoid release into sewage systems or natural bodies of water
Waste Handling: Collect used or expired product in labeled, closed containers
Preferred Disposal: Incinerate in approved, lined facility for biologicals, compliant with local waste rules
Avoided Practices: Do not flush down drains, avoid landfill unless permitted for biological laboratory materials
Handling of Containers: Clean thoroughly if being reused, or dispose as biological waste if single-use
Documentation: Keep disposal records available for laboratory audits
Transport Classification: Not classified as dangerous for transport under most chemical safety rules
Packaging Requirements: Leakproof, sealed vials or jars, inside sturdy outer packaging
Environmental Risks in Transit: Avoid temperature extremes, especially excessive moisture
Spill Response: Clean spills using personal protective equipment, notify carrier if major spill occurs
General Note: Animal-derived, so must comply with documentation requirements for international shipments in some jurisdictions
Relevant Regulations: U.S. OSHA Hazard Communication Standard (29 CFR 1910.1200) recognizes enzyme dusts as potential sensitizers
Labeling Guidance: Biohazard or animal-origin symbol often added for laboratory use
Restricted Uses: Prohibited in foods and drugs without further purification and clearance
Compliant Practice: Follow institution and local government laboratory safety policies
Worker Protection: Proper training and documentation matter for compliance with workplace safety standards
