What is Smoke School?

Smoke school is the process of training someone to visually measure the opacity (density) of smoke or other visible emissions. Why would you want to look at smoke? Facilities that produce visible emissions (smoke, dust, etc.) are required to monitor the opacity of their emissions to ensure they do not exceed an opacity limit. If the limit is exceeded, the facility may be subject to substantial fines.

The U.S. Environmental Protection Agency (EPA) developed a test method to visually measure opacity. This method is called EPA Method 9. Smoke school trains and certifies you in accordance with EPA Method 9. Smoke school is composed of two parts; the lecture course and field testing. The lecture is recommended every 3 years and the field test is required every 6 months.

How AeroMet's Smoke School is Unique


For over 20 years we have been improving the smoke school process to make it as thorough & efficient as possible. Here are some of the ways we are unique:

  • Our online lecture program replaces traditional classroom lectures. The new online program builds off the success of our multimedia lecture that has been in use since 2004.
  • Our smoke generators are custom-built using modern electronics and computer controls. They produce stable, accurate smoke that eliminates the need to guess. You will be an expert smoke reader when you complete our school and we always stay until you certify.
  • Free support for all of our clients. If you have questions about opacity observations, just give us a call and our support team will be glad to help.
  • Federally-Audited. We requested and successfully passed a Federal Audit. Our certification process is highly-respected by industry professionals.
