Cleanup Methods: Absorb spill with inert material, sweep or shovel into properly labeled container for disposal; clean area with detergent and water; ventilate space
Disposal: Dispose of in accordance with local, state, and federal regulations
Decontamination: Avoid flushing uncured material into waterways; use authorized chemical waste disposal
Handling: Use only in well-ventilated areas; avoid breathing vapors or spray; avoid contact with skin or eyes; wash thoroughly after handling; keep away from sources of ignition; use non-sparking tools
Storage: Store in tightly closed containers in cool, dry, well-ventilated location; keep away from direct sunlight, heat, and incompatible materials such as strong acids, strong oxidizers
Other Precautions: Ground and bond containers during transfer; keep separate from food, drink, animal feed; keep containers labeled and securely closed when not in use
Engineering Controls: Provide general and local exhaust ventilation; use enclosures or fume hoods where possible
Exposure Limits: No established specific Occupational Exposure Limit for styrenated phenol; reference OSHA, ACGIH guidelines for similar materials
