Acutely and Extremely Hazardous WastesAcutely and extremely hazardous wastes are wastes that would cause death, disabling personal injury, or serious illness. These wastes are more hazardous than ordinary hazardous wastes.
Acutely hazardous wastes are listed as “P” wastes in the federal system. The main difference between P listed wastes and other federally regulated hazardous wastes is the criterion used to identify acutely hazardous chemicals. The criteria:
- Separates highly toxic (acutely hazardous) waste from other toxic wastes (U listed wastes)
- Establishes the management method for containers that held P listed wastes
