Which organization developed the SLICE-RS mnemonic?

• A. IAFC
• B. ISFSI
• C. Los Angeles Fire Department
• D. Emergency Management Institute

Answer: (B)

SLICE-RS is a structured approach to incident scene size-up and action planning that guides firefighters through a predictable sequence of critical steps, focusing on safety, locating the key area, isolating and containing the incident, and then extinguishing while planning for rescue and salvage. This framework was developed by the International Fire Service Safety Institute to standardize training and decision-making across fireground operations, helping responders share a common mental model and communicate more effectively, especially during command transfers. The other organizations listed are known for different roles—one is a national professional association, another is a federal training institute, and the last is a large city department—but none of them are credited with originating this mnemonic.
