What “type of action” entry should be made on a "lifirs" report when the fire is out upon arrival?

When the fire is out upon arrival, the appropriate type of action entry on a "lifirs" report is "Investigation only." This is because the primary responsibility of the responding personnel in such a scenario is to ascertain the situation, ensure that no fire remains, check for hot spots, and evaluate any potential hazards that may still be present.

Fire suppression and rescue operations would not be applicable here since the fire has already been extinguished and there is no immediate rescue needed if no individuals are in danger. Fire prevention might relate to subsequent measures, but is not relevant as an action taken on site during that specific incident, especially since the report should accurately reflect what was observed and undertaken at the time of response.

Choosing "Investigation only" accurately captures the nature of the response to a situation where the fire has already been controlled or extinguished, focusing on assessment and safety rather than active firefighting or rescue efforts.
