In April 2023, Damasec Mine Action Systems carried out a specialized demolition task in Älvdalen Municipality, Sweden. This project involved the opening of two so-called “explosive chests”—old storage chests for explosives once used in rock blasting for road construction and other infrastructure projects. Since these chests might contain dangerous explosives, professional assistance was essential to manage the potential risks. The municipality had been in close dialogue with Damasec about the project since January 2022, discussing solutions and obtaining necessary permits for handling the chests.
Lost Knowledge and Forgotten Explosives – A Growing Problem
As highlighted by Sveriges Radio, several municipalities today are facing the challenge of “forgotten explosive stockpiles.” Many of the individuals who originally worked with these explosives have either retired or passed away, leading to a loss of essential knowledge about these old explosive chests and, in some cases, even their locations. This includes expertise on safely opening the chests and handling explosives that may be up to 60 years old and potentially unstable.
Safe Opening of Explosive Chests
To tackle the task safely and avoid accidental explosions, Damasec employed a controlled method that involved a small amount of explosive to open the chests. The operation required two carefully planned detonations, one for each chest, to open them securely. Once opened, the chests were inspected, and the explosive contents were carefully removed. A final detonation was then carried out to safely destroy the contents. This approach ensured the entire operation was completed with minimal risk and posed no danger to the surroundings. Inside the two chests, Damasec found explosives and old detonators—materials left behind and forgotten for decades.
Securing and Destroying Old Explosives
Over the years, Damasec Mine Action Systems has developed substantial expertise in securing and destroying old explosives in Denmark, Sweden, and internationally. This project in Älvdalen Municipality exemplifies how Damasec’s expertise can address complex challenges associated with abandoned and potentially hazardous explosives.
The challenges faced by Swedish municipalities with explosive chests underscore the need for specialized companies capable of addressing issues that arise when forgotten explosives are discovered.
