What Is VR Smoke School and How Does It Work?

For decades, EPA Method 9 certification has meant one thing: attending an in-person smoke school, being outdoors, and hoping the weather cooperates. Organizations managing multiple certified readers face the added challenge of coordinating schedules, arranging travel, covering shifts, and dealing with weather-related cancellations — all on a recurring six-month cycle. VirtualOpacity® by Compliance Assurance Associates, Inc. (CAA) was designed to solve these challenges, reshaping the smoke school experience.

Approved by the EPA in August 2024, VirtualOpacity is the first commercial 100% online EPA Method 9 solution. Designated as ALT-152A, VirtualOpacity is CAA's implementation of ALT-152, the EPA's alternate test method for Method 9 certification using virtual reality technology. Using a VR headset and an internet connection, visible emission observers can complete their field certification in as little as 15 minutes for experienced readers.

Combined with CAA's self-paced lecture platform, both EPA Method 9 lecture and field certification are available completely online.

Method 9 Certification Requirements

As with in-person smoke schools, VR certification must be renewed every six months. CAA stores and manages Method 9 field and lecture certifications, accessible 24/7 through our website.

To ensure certifications do not lapse, company contacts and students receive CAA email notifications at 60, 30, and 14 days prior to field certification expiration, depending on account setup.

How VirtualOpacity Works

VirtualOpacity uses a VR headset to simulate the smoke reading experience required for Method 9 certification. Students observe smoke plumes through a VR headset and record their opacity estimates, just as they would at a traditional in-person smoke school — but without the smoke generator, travel, time constraints, or weather dependency.

The platform includes smoke opacity samples and practice exercises that allow students to become comfortable with the VR interface and opacity reading process before beginning actual testing.

The VR field certification process follows EPA Method 9 standards. Students read smoke plumes and enter their opacity readings through the headset interface. Results are graded automatically, and certification is issued immediately upon successful completion. For single users, payment in full is required before certification is released.

Why Organizations Are Choosing VirtualOpacity

Traditional smoke schools require coordinating work coverage, booking travel, and dealing with weather-related conditions. VirtualOpacity eliminates those obstacles.

Available 24/7 — Students can certify any time of year, day or night. No waiting for the next scheduled smoke school or coordinating multiple employees' schedules around a single training date.

No travel required — Students certify from their own location. No flights, hotels, rental cars, or lost workdays spent in transit. For organizations with employees spread across multiple states or facilities, this is a significant cost and time savings.

Weather independent — With traditional smoke schools, students complete their certification outdoors in whatever weather occurs that day — extreme heat, cold, rain, or high winds. VirtualOpacity eliminates exposure to the elements entirely.

Environmentally friendly — VirtualOpacity eliminates emissions from physical smoke generation and the carbon footprint associated with student travel and instructor transport of trucks and smoke generator trailers.

Electronic records — Certification records and testing data for both field certification and the visible emission lecture course are stored and managed by CAA, available 24/7 online.

Ongoing reference — Both training platforms are available 24/7 for refresher training and reference material.

Who Is VR Smoke School Right For?

VirtualOpacity is a strong fit for organizations that need to certify or recertify multiple employees on a regular six-month cycle. It's particularly valuable for:

• Organizations with employees in multiple locations or states
• Teams with tight schedules that make coordinating travel to an in-person school difficult
• Companies looking to reduce training costs without compromising certification quality
• Facilities in remote areas that are far from scheduled in-person smoke schools

The Same Quality of Method 9 Certification

VirtualOpacity does not compromise on the quality or validity of your Method 9 certification. The platform meets the same EPA standards as traditional in-person smoke schools.

Before You Start

Headset Required

You will need an approved virtual reality headset. If you work for an organization, your manager should supply you with one. You can find information on the headset on CAA's VirtualOpacity smoke school page.

Lecture Certification Requirement

To begin using VirtualOpacity, you must have a lecture certification on file in CAA's database. The certificate can be from CAA or another smoke school provider.

For traditional smoke schools, the EPA recommends an initial lecture followed by refresher courses every three years, though some states have their own requirements. The introduction of ALT-152 formalized this approach, making the lecture a prerequisite for VR-based certification rather than just a recommendation.

CAA provides an online lecture certification program that covers the fundamentals of opacity and visible emission observations. It can be completed at your convenience before beginning VR field certification. If you are an employee in an organization, your environmental manager or designated contact will typically enroll you in the online visible emission course and the field portion at the same time.

Enrollment

If you are employed by an organization that has an account with CAA, the designated contact for your organization will enroll you in VirtualOpacity smoke school (and the lecture course, if applicable). You will receive a confirmation email from CAA that includes:

• Your student record number — this is important!
• A link to CAA's webpage that provides an introduction to virtual reality along with a video and user guide for VirtualOpacity
• Information on the self-paced lecture course

If you are an individual user, you will sign up for VirtualOpacity and move through the certification process as directed on the single-user page.

Keep Your Student Record Number Handy

Your CAA student record number will be required when you start VR certification. You'll find it in your enrollment confirmation email, or you can retrieve it from CAA's student record lookup page.
