Impurities: Minimal; varies depending on manufacturer
Hazardous Components: None known under normal processing and use
Inhalation: Move person to fresh air; dust irritation may need medical attention
Eye Contact: Rinse eyes gently with water for at least 15 minutes; seek medical advice if irritation persists
Skin Contact: Rinse exposed skin with soap and water; for contact with molten polymer, cool area with water immediately and seek medical attention
Ingestion: Unlikely during normal handling; if swallowed, rinse mouth and consult physician
Burns: Do not remove molten polymer from skin; cover with clean, wet dressing and get emergency care
Flammability: Polypropylene monofilament burns readily
Suitable Extinguishing Media: Water spray, foam, dry chemical, CO2
Unsuitable Extinguishing Media: Direct water jets can spread burning material
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, aldehydes, hydrocarbons, possible acrolein
Protective Equipment: Firefighters need self-contained breathing apparatus and protective clothing
Special Instructions: Cool adjacent containers with water spray, keep area ventilated to avoid smoke inhalation
Personal Precautions: Avoid inhaling dust, wear gloves if warm or hot material is present
Environmental Precautions: Prevent entry into drains or waterways; collect fibers to avoid environmental contamination
Methods for Clean-Up: Sweep or vacuum spilled product, place into suitable containers for disposal or recycling
Other Precautions: Use non-sparking tools if collecting near ignition sources; ventilation recommended if cutting generates dust
Handling: Use proper lifting techniques for large rolls; avoid creating fine dust; keep away from open flames and high heat sources
Storage Conditions: Store in a cool, dry, well-ventilated location, away from sunlight and strong oxidizers
Packaging Materials: Original packaging, polyethylene liners, closed containers
Incompatibilities: Avoid strong acids, bases, oxidizing agents
Special Requirements: Keep storage area free of combustible materials; label & organize stock to avoid accidental use of damaged or degraded material
Occupational Exposure Limits: Not established for polypropylene itself; nuisance dust (particulate) limit may apply (e.g. OSHA PEL 15 mg/m³ for total dust)
Engineering Controls: Local exhaust ventilation if dust generated by processing
Personal Protective Equipment: Safety glasses for cutting or grinding; gloves for handling hot material; dust mask or respirator for fine particle exposure
Hygiene Measures: Washing hands after handling polymer; do not eat, drink, or smoke in work areas
Environmental Controls: Use containment to prevent spilled material from entering storm sewers or surface waters
