## Summary

Framework output for the Material Symbols Emergency Heat icon in the sharp style.

## Interpretation

Visible referent: emergency heat. Intended message: The icon must communicate Emergency Heat in a digital interface. This Material Symbols asset uses the Sharp style in default interface contexts.

## Diagnostic

Assessing the communicative effectiveness of the Emergency Heat icon

This reviewed catalog report estimates clarity for Emergency Heat in default interface contexts. Scores are screening estimates and do not replace user testing.

## Findings

- Primary referent: emergency heat.
- Implied function: The icon must communicate Emergency Heat in a digital interface..
