Carbon monoxide (CO) is not Carbon dioxide (CO2)
CO = carbon monoxide CO2 = carbon dioxide CO ≠ CO2
You can't see, taste, smell or hear either of these.
One is a result of complete combustion (yay). One is a result of incomplete combustion (uh-oh).
But, due to the Covid pandemic, you're likely hearing about CO2 in schools right now.
Folks, these aren't the same things.
Onto the lesson:
Suddenly, there's all this extra money available to install CO2 monitors for "air quality observation and monitoring." (My thoughts on this are a post for another time.)
CO2 Monitors + Detectors (Covid air quality related) ARE NOT CO monitors, alarms or Detectors (toxic gas detection).
(a) are not measuring the same gas (b) measure gas differently (CO2 measures using infrared sensors, CO detection typically uses electrochemical sensors)
When a CO2 monitor is installed and alerts in your child's classroom, it's shouting:
"Hey! There's not a lot of fresh air in this classroom! This means air (that includes coughs, sneezes now in aerosol particles) between breathing individuals and germs are more likely to spread!"
When a CO alarm or detectors is installed alerts in your child's classroom, it's shouting:
"GET THE EFF OUT OF THIS SPACE AND INTO THE OUTDOORS IMMEDIATELY. DO NOT WAIT. YOU'VE ALREADY BEEN EXPOSED AT A HEALTH-HAZARDOUS AMOUNT. ALERT EVERYONE AROUND YOU AND CALL 911."
So, if you're interested in purchasing a detector for the protection of your child at school, might I interest you in one that focuses on saving their life?
