What protective feature is incorporated into the construction of approved disconnects?

The incorporation of a fusible link that melts in case of fire is an essential safety feature in approved disconnects. This mechanism is designed to provide an automatic response in the event of excessive heat, such as might occur during a fire. When the temperature exceeds a certain threshold, the fusible link melts, thereby disconnecting the gas supply. This action helps to prevent the spread of fire and reduces the risk of further combustible gas being released into a potentially hazardous environment.

This safety feature is crucial in commercial kitchens and other settings where gas appliances are in use, as it adds an additional layer of protection against fire hazards. By ensuring that the gas supply is automatically shut off during a fire, the fusible link aids in safeguarding both equipment and personnel.
