New to Smoke School?

The following information will help you understand what it is and who may need it.


What are Visible Emissions?

Power Plant Emissions

A visible emission is the visible particulate matter that occurs as the result of a process. Smoke exiting a stack at a power plant is a visible emission

Road Emissions

Dust produced from driving down a gravel road is a visible emission

House Emissions

Smoke from the chimney of your fireplace is a visible emission

What is Opacity?

When you’re talking about visible emissions, opacity is the degree to which light is blocked by the emissions. When you are observing emissions there is always a background behind the smoke plume. This background can be anything, but ideally it should contrast with the emissions you are observing.


Opacity with Trees as Background Tree as a background
Opacity with Sky as Background Sky as a background
Opacity with Bricks as Background Building as a background

Step 3: Attend a Smoke School Field Event.

During the field event, our instructors will demonstrate various levels of opacity using a custom smoke generator. After your eyes have been calibrated, they will run practice tests until everyone is ready to take the certification test. AeroMet will run certification tests until everyone passes.

Re-Certification
Step 4:Re-Certification

To maintain your certification, you must pass the field certification test every 6 months. This is why we return to each field event location every 6 months.
