Sweden's icicle hotline keeps pedestrians on the hunt for the diciest ice

With freezing temperatures, frequent snows, and prevailing darkness, the Swedish winters can be difficult to endure. The season can also turn dangerous at the drop of an icicle.

In Stockholm, a falling piece of ice knocked one passerby unconscious Wednesday morning as he turned a corner on Kungsholmen, one of several islands that make up the capital.

The man was fortunate to escape with minor injuries. Falling snow and icicles have killed unsuspecting Stockholmers in the past.

In fact, icicle accidents have become such an annual occurrence in Sweden that the city of Stockholm created an emergency number the public can call when they see icicles or snow banks dangling dangerously over walkways. The messages are then passed along to property owners who are legally responsible for clearing the roofs and can be fined if accidents occur.

So far this winter the hotline has fielded about 600 calls, half of which were taken after Christmas, according to the Swedish newspaper Svenska Dagbladet.

Authorities say the mild weather is to blame for the recent tumbling ice and snow. After weeks of sub-zero conditions, temperatures have settled near the freezing point, weakening the ice’s hold on roofs and overhangs.
