- CISF's role during emergencies like fire is focused on initial response: securing the area, assisting personnel, alerting professional emergency services, and potentially aiding in containment if trained and equipped. - Registering an FIR is a function of the police (station house officer) based on information received about a cognizable offense. While CISF might report the incident to the police, they do not typically register the FIR themselves in the immediate chaos of an active fire.
