Maintaining illumination during emergency situations in large, industrial boats is a difficult task. In most cases, power sources for vessels are limited due to the remote nature of ships at sea. Because of this, and due to the presence of rough, corrosive elements, numerous boats in the industrial sector will use a self-illuminating exit sign to reinforce safety measures.
Tritium Exit Signs
Self-illuminating exit signs are equipped with special coatings that allow the units to light up without electricity or batteries. Additionally, tritium exit signs consume very low energy and do not require activation. During an emergency, individuals will only be able to see the sign clearly in dark environments. Under bright conditions, the panel does not appear illuminated.
The active element inside the sign responsible for illumination is tritium gas. Interestingly, it comes with unstable properties and can be categorized as a radioactive isotype. However, the risk associated with this type of gas is minimal.
To prevent leakage or breakage, a heavy-duty shield encases the tubing, which holds the unstable isotype. This also eliminates tampering and damage during installation.
Most boat LED Lights feature a lifespan of 3-10 years. One of their drawbacks is that they have to be replaced after the expiration date. Furthermore, registration or documentation is needed during purchase and disposal.
By law, such products must be registered with the US Nuclear Regulatory Center (USNRC). The details of the location, operator and contact information of the end user are needed during this process.
Despite the presence of tritium gas, this type of emergency exit sign closely adheres to fire code safety regulations set forth by the NFPA Life Safety Code 101. It is also possible to achieve UL, OSHA and FAA approvals for the units, making the products usable on tightly regulated vessels.
