Who developed the SLICE-RS mnemonic?

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

Answer: (C)

SLICE-RS is a quick, standardized risk assessment used on the fireground to keep safety top of mind and guide decision-making in fast-changing conditions. It provides a concise way to size up hazards, locate yourself and your resources, identify escape routes, and determine when it’s prudent to proceed, pause, or withdraw. This mnemonic was developed by the International Society of Fire Service Instructors, an organization dedicated to creating consistent training and safety guidance for firefighters across departments. Because it comes from ISFSI, SLICE-RS serves as a shared framework that helps crews across different agencies speak the same language during incident operations. The other groups listed are important fire-service entities, but they did not originate this mnemonic.
