Impurities: No hazardous impurities expected under normal use
Inhalation: Remove affected person to fresh air; artificial respiration if breathing stops; seek medical attention for symptoms from heated fumes
Skin Contact: For contact with molten HDPE, cool area with running water—do not attempt to peel material from skin; for dust or solid material, wash skin with soap and water
Eye Contact: Rinse with plenty of water for at least 15 minutes; consult medical attention if irritation persists
Ingestion: Unlikely accidental hazard; rinse mouth, drink water if conscious, seek medical help if discomfort occurs
Note to Physician: Treat burns from molten polymer conventionally; support respiratory and systemic symptoms for inhalation exposure
Suitable Extinguishing Media: Water spray, dry powder, foam, carbon dioxide
Unsuitable Extinguishing Media: Direct water jet for fire in molten pool may cause spatter
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, possible aldehydes, ketones, hydrocarbons, small amounts of irritating fumes
Protective Equipment: Full protective gear, self-contained breathing apparatus
Specific fire-fighting procedures: Cool fire-exposed containers and melt pools with water spray from safe distance
Personal Precautions: Avoid dust formation; ventilate area; wear appropriate respiratory and skin protection when handling large spills of powder or pellets
Environmental Precautions: Prevent entrance into drains, sewers, or water bodies; sweep up spilled granules promptly to prevent environmental loading
Containment and Clean Up: Collect by sweeping or vacuuming; reuse or place in containers for recycling or disposal; avoid creating dust clouds
Methods for Cleaning Up: Use non-sparking tools to gather product; ready absorbent materials for melted or hot polymer spills
Handling: Ground and bond equipment to dissipate static; use with local exhaust for powder or fine granules; avoid breathing dusts or vapors; handle away from ignition sources
Storage Conditions: Store in well-ventilated, dry places, away from direct sunlight, heat sources, strong oxidizing agents;
Packaging Materials: Use original polyethylene bags, FIBC, drums; keep sealed when not in use
Hygiene Practices: Wash hands after handling, remove contaminated clothes
Engineering Measures: Provide ventilation in processing areas; use dust controls where needed; ground all equipment for static prevention
Exposure Limits: No workplace exposure limits for HDPE; use general dust threshold limits (ACGIH TLV for nuisance particulates: 10 mg/m³ total, 3 mg/m³ respirable)
Personal Protection: Safety glasses recommended for routine handling; dust mask or respirator if dust levels high; gloves for mechanical protection; heat-resistant gloves and protective clothing for hot/molten HDPE
Environmental Controls: Use collection and filtration on extruders and grinders; monitor dust and vapor in atmosphere
