Dual Protection From Combustion and Smolder
Nothing is superior to the protection of the life form in any places, especially when it is about the industrial or technical area, where there are many complex and intricate equipment that have the risk of explosion or high temperature. It is important not only as a legal obligation, but also for the mental satisfaction and the moral boost of the employees of that area to have the assurance of safety from flames, and the other secondary problems like that of the smolder or exudate of the combustion gases or particles. There are many methods that can be applied for this purpose, while all share the common goal of provided the much needed safety and security.
But the most commonly used among all are the fire smoke dampers, that serve the dual purpose of passive protection not only from the flames or combustion, but also from gases or particles, which are emitted as a result of the process of combustion. While these can’t be used alone, therefore it is used in combination with the heating, ventilation and air conditioning systems (HVAC) that comprises of the ducts, via which the flames or the gases can easily travel from one place or media to another. Here are some of the unique features that are specific to these:
These are in many way similar to that of the other types of the flame protection dampers in their resistance ration, and the spread of the gases after combustion.
These have a thermal element inside which gets activated as the temperature in the ambiance rises.
The thermal element melts when there is a rise of the temperature above certain level, and thus activating the alarm as well as the functioning of these units.
They are attached to the electrical system, so as to set on the alarm, thus signaling the presence of combustion or gases anywhere in the building.
Their design and application is subjected to variation, because the rule, regulation, standards and testing of this equipment varies from one region to another.
There can be mechanical fire smoke dampers which has the ability to shut down the cross sectional area of the duct or pipe when there is an incident of combustion, thereby providing resistance from flames and the potential of hazards that it may cause.
