Fire Safety: The Role of Fusible Links

Discover the critical role of fusible links in ensuring fire safety and why their regular inspection is paramount for protecting your establishment.

It’s crucial to inspect fusible links during your Fire Suppression Inspection every six months. Unfortunately, this task often gets forgotten, mainly because the kitchen can get really hot from cooking or because the system is busy doing its job while the inspection is happening. However, skipping this step and not replacing these links regularly can seriously affect how well your system works in case of a fire, or it might even accidentally go off when you don’t want it to.

Fusible links are essential in helping your suppression system detect fires automatically in your commercial kitchen. To follow the rules set by NFPA 17A, you must change these links every six months. It’s also important to use the right one that matches the heat level of your kitchen appliances. One practical way to make sure you’re doing this correctly is to ask your service provider to swap out the links during each service visit with ones that have the current year marked on them. At Boss Fire Protection, we take photos to show that we’ve replaced them every time, giving our customers peace of mind.

Now, let’s explore how a fusible link actually works:

Step 1: Normal Operations When everything is running smoothly in the kitchen, the fusible link remains solid, keeping the fire suppression system connected.

Step 2: Temperature Rise If a fire breaks out, the temperature around the link increases. Different links react to different levels of heat.

Step 3: Melting Point As the temperature surpasses the link’s designated melting point, it starts to soften and eventually melts.

Step 4: Mechanical Release Once melted, the fusible link triggers a mechanism that activates the fire suppression system, causing it to release fire suppressant to control the flames.
