⚠️ Carbon Monoxide (CO) PPM Safe Levels — Quick Chart + Action Guide

CO is odorless and invisible, but it can become dangerous fast. I made a simple ppm quick reference so you can understand what’s normal, what’s high, and when to evacuate.

✅ Includes:
• PPM ranges (0–9 / 10–34 / 35–69 / 70–199 / 200+)
• Key limits (EPA / WHO + workplace references)
• What to do if the alarm sounds
