Kharkiv Metro Can Withstand a Nuclear Strike: How the 19-Ton Airtight Seal Works.

Unique Protection Mechanism of Kharkiv Metro

According to Novyny.live: Kharkiv Metro has a unique mechanism that allows it to withstand a nuclear strike — an airtight seal weighing 19 tons. The construction of the metro began in Soviet times with consideration for the possibility of nuclear war, and this seal is a crucial part of the protection system.

The airtight seal closes at each metro station, providing additional protection in case of an emergency. These seals can withstand an impact of 1 megaton. For comparison, the atomic bomb dropped on Hiroshima had a yield of 15 kilotons, indicating the high reliability of the protective system.

Importance of Airtight Seals

At the beginning of the war, the seals were closed every night and opened at 6 a.m., ensuring the safety of passengers and staff. The conditions under which the metro operates underscore the importance of such safety measures in the modern world. According to Oleksandr Petrovskyi, the airtight seal is a critically important element of protection for all who use this mode of transport.

The situation in Ukraine, especially in the context of military conflicts, highlights the necessity for reliable security systems such as airtight seals in the metro. This is not only a means of protection against nuclear threats but also an important component of the overall infrastructure that ensures the safety of citizens in crisis situations. Although historically these systems were developed with potential disasters in mind, their relevance remains high in the face of modern challenges.
