These regulations typically involve restrictions in four general areas: 

1. Discharge or use requirements – These regulations usually limit or prohibit the use of AFFF in training or testing exercises, and only allow the use of AFFF in active firefighting situations;
2. Storage or “take-back” provisions – Some states have enacted state run programs to purchase and dispose of AFFF, usually purchasing from government agencies;
3. Notification or reporting requirements – When continued use of AFFF is allowed, some states have required that businesses report specific details regarding their use; and
4. Limitations on personal protective equipment (“PPE”) – In some cases states have limited or prohibited PPE for firefighters that contains PFAS-materials.
