The person generating the waste is ultimately responsible for the waste he or she produces. Below are general policies regarding hazardous waste accumulation and management:<\/p>\n\n\n\n

Satellite Accumulation Area (SAA)<\/h2>\n\n\n\n
\"hazardous<\/figure>\n\n\n\n

Every area where chemical waste is produced and accumulated until the waste containers are full is called a Satellite Accumulation Area (SAA). Here are the rules to be followed for its management:<\/p>\n\n\n\n

    \n
  • Waste being generated elsewhere should not be kept in this area.<\/li>\n\n\n\n
  • If the area accumulates acutely hazardous waste, one quart is the maximum amount allowed to be accumulated. If not acutely hazardous, 55 gallons of waste is the limit.<\/li>\n\n\n\n
  • The SAA must be located in a dry and cool location away from direct sunlight.<\/li>\n\n\n\n
  • The SAA must have a sign with the words “Hazardous Waste Satellite Accumulation Area.”<\/li>\n\n\n\n
  • Waste must be kept inside a dishwashing pan, basin or tub to prevent spills.<\/li>\n\n\n\n
  • Waste must be segregated from incompatible chemicals.<\/li>\n<\/ul>\n\n\n\n

    Waste containers<\/h2>\n\n\n\n
    \"a<\/figure>\n\n\n\n
      \n
    • Use only one container per waste stream.<\/li>\n\n\n\n
    • The container must be compatible with the waste inside and free from cracks, leaks, corrosion or any sign of degradation.<\/li>\n\n\n\n
    • The container must be clean on the outside.<\/li>\n\n\n\n
    • Never overfill a waste container. A container filled to 80% of its capacity is considered full.<\/li>\n\n\n\n
    • Recycled containers must have the original label defaced to avoid confusion regarding contents.<\/li>\n\n\n\n
    • The container holding hazardous waste must be closed with a screw cap at ALL TIMES except when waste is being added.<\/li>\n<\/ul>\n\n\n\n

      Note: Disposal cost is based on waste type and container size, not amount of waste. Please choose a container that fits the quantity or volume and, when possible, combine compatible waste.<\/em><\/strong><\/p>\n\n\n\n

      Waste labels<\/h2>\n\n\n\n
        \n
      • Give FULL NAME of contents, no abbreviations, codes, or omission of any of the information on the label is allowed.<\/li>\n\n\n\n
      • The container holding the hazardous waste must be marked with the words “Hazardous Waste”, and must list components and their percentages(Must equal 100%). Also, check the type of hazard (Ignitable, corrosive, reactive or toxic).<\/li>\n\n\n\n
      • Date container once it is full.<\/li>\n<\/ul>\n\n\n\n
