Hazardous Components: No regulated hazardous ingredients in typical polycarbonate grades
Inhalation: Move to fresh air, support breathing, seek medical aid if cough or irritation develops after inhaling dust or fumes from machining
Skin Contact: Remove contaminated clothing, rinse exposed skin with soap and water if melted polymer contacts skin, seek medical help for burns or persistent irritation
Eye Contact: Flush with water for at least 15 minutes if dust or hot polymer enters eyes, continue rinsing and get ophthalmological assessment
Ingestion: Rinse mouth, drink water, avoid inducing vomiting, obtain medical attention if symptoms persist
Most Important Symptoms: Mechanical irritation, burns from molten polymer, headache from fumes
Notes to Physician: Treat symptomatically according to exposure type
Suitable Extinguishing Media: Use water fog, dry chemical, foam, or carbon dioxide for small fires
Unsuitable Media: Avoid high-pressure water stalks which may spread burning material
Specific Hazards: Sustained burning possible at high temperature, toxic fumes include carbon monoxide, carbon dioxide, possible phenolic compounds
Special Protective Equipment: Firefighters need self-contained breathing apparatus and full protective gear
Explosion Data: Fine dust accumulation presents ignition hazards in processing plants
Thermal Decomposition: Decomposition may release irritating or dangerous gases such as bisphenol A, phenol, diphenyl carbonate
Personal Precautions: Wear gloves, goggles, and dust mask to control contact and inhalation risk in the event of dust or pellet spills
Environmental Precautions: Prevent entry of spilled material into aquatic networks, municipal sewers, or stormwater drains
Methods for Cleaning Up: Sweep up pellets or vacuum dust, use spark-proof tools, store collected waste in designated containers for re-use or proper disposal
Other Precautions: Report large spills to site safety personnel, ensure adequate ventilation in processing zones after fire or thermal event
Handling: Handle with care to reduce dust, keep containers closed, avoid breathing fumes from molten or burned plastic
Storage: Store indoors in dry, cool, well-ventilated spaces, keep away from strong oxidizers, acids, alkalis, or ignition sources
Packaging Materials: Use original or approved containers, protect from physical damage and moisture
Special Considerations: Rotate inventory, shield from direct sunlight to reduce thermal or UV degradation
Hygiene Practices: Wash hands before eating, drinking, or smoking after handling polycarbonate granules or parts
Exposure Limits: No formal occupational limits for PC dust, but maintain minimal airborne concentrations
Engineering Controls: Install local exhaust at processing equipment, maintain ambient air quality with general ventilation
Respiratory Protection: Use approved dust masks or respirators if dust formation exceeds recommended levels, or if fumes build up during high-heat operations
Skin Protection: Wear heat-resistant gloves and long sleeves to handle hot or molten polymer, regular chemical gloves suffice for granules
Eye Protection: Use safety goggles or face shields during pellet handling, processing, or when wind may blow dust or chips
Other Protective Measures: Eyewash stations and emergency showers should be accessible in all production settings where polycarbonate is melted or formed
Appearance: Transparent to slightly opaque granules or molded shapes, various colored & uncolored

Decomposition Temperature: Begins at 300°C (572°F)
Viscosity: N/A to granules and solid parts
Stability: Remains stable under standard conditions of use and storage
Incompatible Materials: Strong acids, bases, oxidizing agents, halogens cause degradation or chemical reactions
Hazardous Decomposition: Releases carbon monoxide, carbon dioxide, possibly phenol, bisphenol A vapors at high heat
Hazardous Polymerization: Will not occur under recommended use
Other Reactivity Notes: Absorbs moisture over time, may hydrolyze slowly in warm aqueous alkaline environments
Conditions to Avoid: Avoid overheating, prolonged sunlight exposure, and strong mechanical shock to minimize physical changes
Acute Toxicity: Not harmful under regular handling, minimal toxicity as solid material
Chronic Toxicity: Repeated inhalation of dust could cause respiratory tract discomfort
Skin Corrosion/Irritation: No evidence of irritation for intact skin, molten polymer causes burns
Eye Effects: Mechanical irritation from dust or chips, severe damage from splashes of hot material
Respiratory Effects: Heated fumes can cause short-term irritation, minimum risk with effective controls
Carcinogenicity: No classification by IARC or OSHA for finished polycarbonate; residual BPA monomer not a risk at trivial levels
Mutagenicity / Teratogenicity: Not identified as mutagenic or teratogenic in current literature
Other Data: Medical-grade and food-grade polycarbonate complies with relevant health standards
Ecotoxicity: Large pellet or dust spills harm aquatic animals by ingestion or physical blockage
Persistence and Degradability: Extremely slow to degrade, typical persistence in natural environments for decades
Bioaccumulation: No significant bioaccumulation expected
Mobility in Soil: Settles in terrestrial environments, may be carried by runoff as microplastics
Other Adverse Effects: Improper disposal exacerbates plastic pollution, affecting waterways and land ecosystems
Decomposition: Sunlight and UV cause slow physical breakdown, not true mineralization
Regulatory Listings: Not classified as environmentally hazardous under most national standards, ongoing global scrutiny for plastic waste risks
Waste Disposal Methods: Prefer mechanical recycling or energy recovery, solid landfill disposal remains common for non-recyclable or mixed grades
Incineration: Permitted where local regulation allows, only in properly equipped facilities with emission controls
Waste Codes: Check local and national codes for plastic (thermoplastic polymer) disposal
Handling Considerations: Do not release dust, granules, or finished pieces into natural water bodies or municipal drainage
Packaging Disposal: Recycle or send to approved waste handler according to resin code and regional policy
