Fire doors and windows information

What level of fire doors should be used in the kitchen?

In home decoration, the kitchen, as the main place for home cooking, is also one of the areas with a relatively high probability of fire. Therefore, in the process of kitchen decoration, it is very important to choose the right fire door. However, in the actual decoration process, many people still have a vague understanding of fire doors. Next, let’s discuss in detail how many levels of fire doors should be used in the kitchen.

First of all, we need to understand the causes and characteristics of fires in the kitchen. The main cause of kitchen fires is the fire caused by cooking fumes. This kind of fire is characterized by burning fast, difficult to control, and producing a lot of smoke and high temperature. Therefore, for the kitchen fire door, its fire rating should be at least B1 level or above.

In addition, when purchasing fire doors, we need to pay attention to the following aspects:

1. The material of the fire door. The material of the fire door is preferably steel plate or other special materials. These materials have a high density and can play a very good fireproof effect. And some low-grade fire doors will use wooden materials, so the fire prevention effect is relatively poor.

2. The fire protection time of the fire door. Fire time refers to the period of time a fire door can withstand fire temperatures and then continue to maintain its structural integrity and insulation. Generally speaking, the fire prevention time of kitchen fire doors should be more than 30 minutes.

3. The tightness of the fire door. The tightness of the fire door refers to whether the fire door can effectively prevent the high temperature, dense smoke and other harmful gases generated during the fire from entering other areas. Therefore, the cracks of the fire doors should be tight, and a certain gap should be maintained between the contact surface of the door leaf and the door frame to prevent the fire from spreading through the cracks.

4. Installation of fire doors. The installation of fire doors should be carried out by professionals, and the installation location and size should strictly follow the design specifications to ensure the fire protection effect of fire doors.

In short, for the kitchen, the choice of fire doors should at least meet the fire rating above B1 level, and the material and sealing performance should also be guaranteed. At the same time, in daily use, we must also pay attention to the safety of the kitchen, clean up oil stains such as range hoods in time, and do not store flammable items in the kitchen in case of a fire.
