Extinguishant

Extinguishing agents are substances which have a deletion, and can therefore be used to extinguish fires. They are used for firefighting by the fire or automatic fire extinguishing systems, or themselves in hand-held portable fire extinguishers or fire extinguishers available. Each substance has a principal extinguishing efect and possyply a second. A wrong choice of extinguishing agent can lead to fatal consequences.

Extinguishing systems

Sprinklers

Fire sprinkler systems are in the category. The sprinkler system is a automatic extinguishing system. It prevents a fire developed into a major fire. On the one hand, to the people more time to leave the danger zone to give, on the other hand, to protect the building itself and its facilities before the destructive fury of the flames. Sprinkler systems are usually as in public buildings (department stores, office buildings, etc.)

But when the sprinkler system triggers?

Sprinkler heads are sealed with glass ampoules, which are filled with a special colored liquid. A fire warms the special liquid into the glass ampoules and begins to expand, wherein the ampoule bursts open so that the noozles and outlet water from the sprinkler piping. In a fire selectively open only the sprinklers, the ampoules have reached the activation temperature. The color of the liquid indicates the trip temperature.

Sprinkler systems are fundamentally different in wet and drying. In the wet pipe sprinkler piping is always filled with water. Wet systems are therefore very quick to deloy. However, make sure that they are installed only in frost-free areas. In areas where there is a risk of frost and could freeze the sprinkler piping be used so-called dewatering. In these plants, the pipeline network is filled woth compressed air. It was only after triggering of the sprinkler system is filled with water.
