Difference between above-ground fire hydrants and above-ground foam fire hydrants

However, after checking various sources carefully, it seems that apart from slight differences in appearance, there is no fundamental difference between the two. I wonder why they need to be designed as two different types – ordinary fire hydrants can also be used as foam fire hydrants. Moreover, fire hydrant manufacturers say that there is still no **standard** for above-ground foam fire hydrants
Above-ground hoses can be used to deliver both fire foam and fire water. What’s the difference? At my previous workplace, we would place markers or labels on fixtures used for different purposes in order to distinguish between foam and fire extinguishing water.
It is designed in two styles to distinguish between fire hydrants for water-based firefighting and foam hydrants; they serve different purposes. Foam is used to extinguish fires involving flammable and explosive materials as well as oils, while fire water can not only be used to put out ordinary fires but also for flushing purposes, among other uses
You mean not to use another separate system, but to use just one system; if foam is needed, then foam should be used, right? It’s a good idea. Perhaps it’s because of the emphasis placed on this aspect – systems that use foam don’t have a water function, as there’s a fear of using them incorrectly. That’s what I think, haha
Above-ground fire hydrants and above-ground foam fire hydrants belong to two separate systems: above-ground fire hydrants are part of the fire water supply network system, which is further divided into high-pressure and low-pressure fire water supply networks. Foam fire hydrants are part of the foam fire station system. Of course, the foam system requires a high-pressure fire water supply network to provide the water for mixing the foam solution.
Their structure and such are the same; it’s only their external coloring that differs. In our company, the above-ground fire hydrants are red, while the foam hydrants are yellow. The reason for this is to prevent accidental misuse – using the wrong type of extinguishing agent could lead to more serious consequences.
I agree with what was said on the sixth floor; it’s better to make a distinction. We’re all using red colors now, so I’ll have them use markers to indicate it
