Purity: Typically >99% HDPE resin
Additives: May contain small quantities of processing aids, pigments, stabilizers (exact formulation depends on grade and application)
Inhalation: Remove to fresh air if exposed to fumes from overheating; seek medical attention if symptoms develop
Skin Contact: Cool affected area with water, do not attempt to remove solidified polymer from skin; seek medical help for burns
Eye Contact: Rinse with clean water if particles enter eyes; obtain medical attention for discomfort
Ingestion: Not regarded as hazardous by ingestion, but seek medical advice if symptoms occur
Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Unsuitable Extinguishing Media: Avoid direct stream of water as it may spread molten material
Fire Hazards: Burns rapidly with a high heat release; melting product may flow and spread fire
Hazardous Combustion Products: May produce carbon monoxide, carbon dioxide, aliphatic and aromatic hydrocarbons
Protective Equipment: Firefighters should wear full protective clothing, including self-contained breathing apparatus
Personal Precautions: Use gloves to avoid contact with molten polymer, avoid creating dust
Environmental Precautions: Prevent pellets, granules or powder from reaching drains, waterways, or soil
Cleanup Methods: Sweep up spilled material for recycling or disposal; avoid dust generation; ventilate if in enclosed area
Disposal of Cleanup Materials: Place in suitable containers for disposal or recycling as appropriate
Safe Handling: Avoid breathing dust or processing fumes, wash hands after handling, use mechanical ventilation where heated
Storage Conditions: Store away from direct sunlight, heat sources, and incompatible materials
Packaging Materials: Store in bags, bulk containers, or silos suitable for plastics
Incompatibilities: Strong oxidizing agents can trigger reactions with HDPE
Occupational Exposure Limits: No exposure limits established for HDPE as a solid
Engineering Controls: Provide adequate ventilation in areas where dust or processing fumes may develop
Personal Protective Equipment: Safety glasses to prevent eye contact with dust, heat-resistant gloves when handling hot material, respiratory protection if threshold limit for nuisance dust or fumes is exceeded
General Hygiene Measures: Wash hands thoroughly after handling; remove contaminated clothing before eating, drinking, or smoking
