  1. Flush with clean water for at least 15 minutes ✔
  2. Have the hiker rub the eye

Why: Flushing dilutes and removes the chemical before it burns more tissue. Hold the eyelid open and flush from the inner corner outward.

Huh, didn't know that: For a speck of grit, blink and flush, but never rub the eye.
