According to this story, the welding was specifically as a result of the ammonium nitrate: > In January 2020, a judge launched an official investigation after it was discovered that Hangar 12 was unguarded, had a hole in its southern wall and one of its doors dislodged, meaning the hazardous material was at risk of being stolen. > In his final report following the investigation, Prosecutor General Oweidat “gave orders immediately” to ensure hangar doors and holes were repaired and security provided, a second high-ranking security official who also requested anonymity said. > ...During the work, sparks from welding took hold and fire started to spread, the official said. It's really mind-boggling. https://uk.reuters.com/article/uk-lebanon-security-blast-documents-excl/exclusive-lebanons-leaders-warned-in-july-about-explosives-at-port-documents-idUKKCN2562L3 https://uk.reuters.com/article/uk-lebanon-security-blast-doc...
