Black Seal High Pressure
Boiler Operator

Black Seal High-Pressure Operator Overview

The New Jersey Black Seal High Pressure license is required for boilers over 100 horsepower and more than 15 pounds pressure steam. If it's a hot water heating system the boilers must be over 160 psi with a water temperature over 250° Fahrenheit. This classification of boiler operator’s license is a prerequisite for blue seal eligibility (operating engineer/stationary engineer with complimenting refrigeration license).

Experience

The state of New Jersey and New Jersey Department of Labor and Workforce Development requires 90 days of experience in a location or boiler plant that has a boiler that is over 100 horsepower or has over 4 million BTUs with a pressure greater than 15 psi for steam and greater than 160 PSI if it's a hot water system to be eligible for a high pressure black seal license exam. If you're from out of state and work a boiler that is over 100 horsepower or 4 million BTUs, you can qualify to become a licensed operator, provided that we can show your experience in the form of endorsement letters, which we can provide you a template for. See NJ code for Black Seal HP (12:90-8.6).

If you don't have prior experience, please explore The Externship Program!

Endorsements

Provide an endorsement from a manager from your place of employment for your application. If your boilers are over 500 horsepower, you also need two licensed engineers' signatures to endorse your application (personnel with a blue, red, or gold seal license). Provide our school with NJ state inspection certificates. These certificates can be found hanging in your boiler room framed behind glass. They contain all the information that we need to fill out your application properly. Navy personnel can provide us with your DD 214 and the experience of equipment found on ships that you served on.  Our school can go forward and get you a license based on that experience.

Test

Your test consists of a 50-question multiple-choice test, and the passing score is 66%.
