Blue Seal Engineer 1-C Overview:

The Blue Seal license is required for boilers over 500 hp and greater than 15 pounds pressure steam. 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.


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).


The application will require management endorsement, along with two engineer endorsements (personnel who have a blue red or goals seal license). Out-of-state and Navy personnel can obtain a license, provided they have worked at least four years in the plant with such horsepower. However, we would need letters of endorsement from the company. These letters would state the boiler horsepower and all the necessary information needed about the equipment to provide the state. These applications must be approved on a case-by-case situation. One can skip the Black Seal license with the necessary background to state requires.
