## Root Cause

Wet gauze or cloth masks quickly become clogged with fine ash particles, reducing airflow and causing breathing difficulty; they also do not filter out toxic gases like sulfur dioxide.

## Workarounds

1. **Use a dry N95 or P100 respirator mask if available; if not, stay indoors with windows and doors sealed, and use a damp cloth only as a last resort, replacing it frequently.** (85% success)

## Dead Ends

- **** — Multiple layers of wet fabric create a dense barrier that clogs quickly with ash, making it hard to breathe and inducing panic. (70% fail)
- **** — This makes the mask even more impermeable and can cause inhalation of harmful vapors, increasing respiratory distress. (65% fail)
