HI-FOG® Protects Finnish Tunnel

Marioff Corporation Oy announced that it has been selected to install a HI-FOG® Water Mist Fire Protection System in Helsinki's new underground tunnel service network. The installation will be Finland's first automatic tunnel fire protection system. Marioff is part of UTC Fire & Security, a unit of United Technologies Corp.

The Helsinki underground service network will allow the city to expand its pedestrian zones by limiting traffic through the downtown area. The project includes a two-kilometre service tunnel, one kilometre of which will be protected by the new HI-FOG® system.

"This is a very important project for Helsinki, and we are pleased to be working with the City's planners to make the service tunnels safer," said Markku Vuorisalo, Marioff's General Manager of Transportation and Infrastructure.

The HI-FOG® system uses high pressure to produce a fine water mist that combines the extinguishing characteristics of water with the penetrative qualities of gases to minimize property damage and environmental hazard upon activation.

"HI-FOG® has proven to be highly suitable for a variety of land-based applications, especially in retro-fitting, where its thin tubes and multiple power options have given it a significant advantage over competing products," says Vuorisalo.

Construction of the Helsinki service tunnel is coordinated by the Public Works Department of the City of Helsinki. All the equipment contracts for the project were publicly tendered, including the fire protection system in the summer of 2007.
