A civil defence shelter is a separate room or separate structure provided inside or in connection with a building. Its task is to protect the people at locations where they normally move, work, and live. The purpose of the defence shelter is to protect people against toxic spills, radioactive fallout, or a military attack, for example. In Finland, civil defence shelters are mainly intended for protection during armed conflicts.

The purpose of civil defence is to protect the civilian population and non-military persons during wars, armed conflicts and battles. The construction of civil defence shelters is included under civil defence. The Ministry of the Interior manages and co-ordinates national arrangements of civil defence. The construction and upkeep of civil defence shelters is regulated by the Rescue Act.

Karanttia has over 37 years of experience in the construction of prefabricated civil defence shelters complying with official regulations. Our unique expertise ensures the most comprehensive and reliable information for architects and other construction professionals. Our experts are at your service in all matters related to civil defence shelter design and construction.

Civil defence is related to exceptional situations in which people and property are protected and emergency measures are prepared for. Civil defence is also an important part of rescue operations, which involve minimisation of damages and injuries from accidents and first aid. In Finland, rescue operations are managed by the Ministry of the Interior, which supervises the Rescue Services and is liable for their service capacity.

According to Section 1 of the Civil Defence Act, the purpose of civil defence is to protect the population and property against damage resulting from war and other comparable circumstances, as well as to limit the damage caused by them and mitigate their consequences.

In Finland, rescue operations are managed by the Ministry of the Interior, which supervises the Rescue Services and is liable for their service capacity. Instructions for citizens on practical measures related to civil defence are always accompanied with guidelines from the Ministry of the Interior, the Rescue Services, and municipal authorities.

Based on the Finnish value system, for more than five decades, we have sought to equally protect all citizens instead of just soldiers and leaders by building civil defence shelters throughout the country. The Finnish civil defence shelter construction system has been an ingenious solution, as the shelters have been built in connection with other construction. The costs for the construction have been paid by the owner of the building, who in turn has had the possibility to decide how the shelter is to be used under normal circumstances. We, Finns, should be proud of such an achievement.

In Finland, modern civil defence shelters have been built since 1959. The justification has been the necessity to guarantee basic security. Building civil defence shelters in the hour of need is difficult or even impossible. Because of this, they must be designed and built under normal circumstances with a long-term outlook. By a legislative amendment in 2011, the deployment term of the civil defence shelters was extended from one day to three. This means that in normal times, more attention must be paid to the condition of civil defence shelters.

According to VSSR, a civil engineering protection association, a large majority of Finns still support construction of civil defence shelters. Eight years ago, the feeling of insecurity among Finns was more common than ever since 1990. Today, the situation is even worse.
