First Aid Measures

Inhalation: Move to fresh air immediately, keep at rest, seek medical attention for persistent symptoms such as wheezing or shortness of breath
Skin Contact: Remove contaminated clothing, rinse skin generously with soap and cool water, monitor for allergic rash
Eye Contact: Rinse gently with water for at least 10 minutes, remove contact lenses if present, seek evaluation for persistent discomfort
Ingestion: Rinse mouth with water, drink water to dilute, seek medical advice if large amounts consumed or symptoms develop
Note for Physicians: Treat symptomatically, pay attention to signs of respiratory sensitization

Fire-Fighting Measures

Suitable Extinguishing Media: CO₂, dry chemical, foam, or water spray
Unsuitable Extinguishing Media: Strong water jets may spread powder
Combustion Hazards: Enzyme powders can form combustible dust in air, producing carbon oxides and nitrogen oxides upon burning
Protective Equipment: Full emergency gear, self-contained breathing apparatus
Firefighting Procedures: Control dust clouds, contain run-off water to prevent environmental contamination

Accidental Release Measures

Personal Precautions: Wear dust mask, chemical safety glasses, gloves, and lab coat; use local exhaust ventilation
Environmental Precautions: Prevent runoff into sewers, surface water, or drains
Spill Cleanup Methods: Gently sweep or vacuum without raising dust, use damp absorbent material for remaining residues, transfer to labeled waste containers
Decontamination: Rinse spill area with plenty of water after dry clean-up

Handling and Storage

Handling: Open containers with care to minimize dust, work within a chemical fume hood where possible, always wash hands after handling, do not eat/drink/smoke when using this material
Storage: Store in tightly-sealed container, avoid moisture exposure, keep at 2–8°C (refrigeration recommended unless otherwise specified), restrict access to trained personnel
Incompatibilities: Strong acids, oxidizers may degrade protein component or generate hazardous byproducts

Exposure Controls and Personal Protection

Engineering Controls: Local exhaust ventilation, keep dust levels below 1 mg/m³
Respiratory Protection: Particulate-filtering mask (P2 or N95 standard), especially during weighing or mixing
Eye Protection: Chemical splash goggles
Skin Protection: Nitrile or latex rubber gloves, laboratory coat
Hygiene Measures: Wash hands, face, and exposed skin thoroughly after handling, remove soiled clothing and launder before reuse
Occupational Exposure Limits: No established limits for this enzyme, avoid prolonged or repeated inhalation exposure

Stability and Reactivity

Chemical Stability: Stable under normal conditions, sensitive to extreme heat and strong acids or bases
Hazardous Reactions: None known under recommended storage/use
Conditions to Avoid: Excess humidity, high temperature, open flames
Incompatible Materials: Powerful oxidants, strong acids, alkalis
Hazardous Decomposition: Combustion can yield carbon monoxide, carbon dioxide, nitrogen oxides

Toxicological Information

Routes of Exposure: Inhalation, skin, eyes, ingestion
Acute Toxicity: No data indicating acute oral, dermal, or inhalation toxicity for maltase enzyme from dietary sources; may trigger allergy/asthma in predisposed individuals
Irritation: Mild, typically limited to skin and eyes upon contact; pre-existing allergies may exacerbate
Sensitization: Some risk in occupational settings for respiratory/skin sensitization; sensitization risk grows with repeated handling
Chronic Effects: No carcinogenic, mutagenic, reproductive risks identified by IARC, NTP, OSHA
Medical Symptoms: Wheezing, sneezing, red or itchy skin, watery eyes possible with direct contact or airborne enzyme dust

Ecological Information

Ecotoxicity: Enzymatic protein biodegradable under environmental conditions, not classified as dangerous for aquatic life at anticipated concentrations
Persistence and Degradability: Rapidly broken down by soil and aquatic microorganisms
Bioaccumulation Potential: Does not bioaccumulate
Mobility in Soil: Highly mobile in water, broken down by natural processes
Other Adverse Effects: Excessive release into water may contribute to nutrient enrichment (eutrophication)

Disposal Considerations

Waste Treatment Methods: Small laboratory quantities can be flushed with ample water if permitted, avoid large-scale water disposal
Disposal Containers: Tight-sealing, clearly labeled chemical waste containers
Recommended Disposal: Incineration or landfill in compliance with local, regional, and national regulations
Contaminated Packaging: Rinse thoroughly or dispose as chemical waste
Additional Information: Consult licensed waste disposal contractor for bulk quantities
