The Soviet steamer Dalstroy (formerly known as the Yagoda) operated in the 1930s and 1940s from the port of Nakhodka to Magadan, delivering cargo and prisoners to Kolyma.
On July 24, 1946, during the loading of ammonal in Nakhodka, an explosion occurred due to gross safety violations.
In one of the holds, as a result of careless handling and a serious breach of safety precautions, seven thousand tons of ammonal had started to burn while being loaded onto the Dalstroy.
In another hold, because of the increased heat, four hundred tons of TNT exploded completely destroying the port facilities at Cape Astafieva and causing numerous casualties.
Some of the ship’s crew, having disembarked shortly before the explosion, were in a protected area and sustained only minor injuries.
