Acute Hazardous Waste

Definition

Acute hazardous waste are comprised of listed hazardous wastes with certain waste codes. These codes are:Sodium cyanide

  • From "F list" hazardous waste from non-specific sources F020, F021, F022, F023, F026 and F027
  • From "P list" acute hazardous commercial chemical products and manufacturing chemical intermediates
  • All "P list" waste codes are acute hazardous wastes. Note that this applies only to unused materials that are pure, technical grade, or formulations in which the listed chemical is the sole active ingredient

The full descriptions appear in the hazardous waste regulations in Ch. NR 661, Wisconsin Administrative Code.

Campus and UW System facility considerations

In general, any P-list chemical can appear as a waste at a UW campus, depending on the instructional and research needs of your campus faculty.

As a practical matter, F027 is the only one of the acutely hazardous F-list chemicals that has been noted to appear as a waste at UW campuses. In Wisconsin, this includes only unused formulations containing tri–, tetra–or pentachlorophenol or compounds derived from these chlorophenols .

Acute hazardous waste is a particularly important waste management concern for campuses or facilities that are Very Small Quantity Generators ( VSQGs ) or Small Quantity Generators ( SQGs ), since 1 kg (about one quart) of accumulation will change your status to Large Quantity Generator. This change will increase costs and add work, including requirements that you must:

  • ship waste within 90 days of first accumulation
  • have a written contingency plans
  • maintain written job titles, list of personnel filling those positions, and job descriptions for waste facility personnel
  • train your waste personnel annually
  • document training
  • file an annual hazardous waste report with WDNR
  • have a designated emergency coordinator
  • have a record of agreement with off-site emergency responders
  • comply with other prepared and prevention items

The best way to avoid headaches from acute waste is to limit your generation of these wastes .
