Blue Seal

Blue Seal Engineer 1-C Overview

The Blue Seal license is required for boilers over 500 hp and greater than 15 pounds of steam pressure. If it is a hot water heating system, the boilers must be over 160 psi with a water temperature over 250° Fahrenheit.  Any plant that generates electricity with a prime mover that is over 6 hp and not greater than 100 hp requires a blue seal license.

Experience

To be eligible for this license, one must possess a black seal high pressure boiler operator's license for a period of at least six months and show experience on equipment that is over 500 boiler horsepower. Equipment must high-pressure boiler equipment, which means the boilers must be over 15 psi for steam and over 160 PSI for hot water.  Prime movers 6 hp up to 100 hp require a blue seal license. See NJ code for Blue Seal (12:90-8.8).

Endorsements

The application will require management endorsement and one engineer's endorsement (personnel with a Blue, Red, or Gold Seal license). Out-of-state and Navy personnel can obtain a license, provided they have worked at least two years in a plant over 500 horsepower. However, the state would require a letter of endorsement from the company signed by management. This letter would state the boiler horsepower, all the information needed about the equipment, and the length of time you have operated the boilers. These applications must be approved on a case-by-case situation. An applicant can skip the Black Seal license with the necessary background to state requirements.
