Many　construction　accidents　occur　in　China　each　year,　leading　to　a　large　number　of　deaths,　injures,　and　property　losses.　Due　to　the　outbreak　of　COVID-19,　little　attention　is　paid　to　construction　safety,　resulting　in　severe　accidents.　To　prevent　construction　accidents　and　learn　to　how　address　safety　issues　in　future　pandemics,　this　study　proposed　an　improved　STAMP　(Systems　Theoretic　Accident　Modeling　and　Processes)　model　to　analyze　the　collapse　accident　of　the　Xinjia　Express　Hotel　used　for　COVID-19　quarantine　in　China.　Through　the　application　of　the　STAMP　approach,　the　causes　of　the　construction　accident　and　the　relationship　between　various　causal　factors　are　analyzed　from　a　systematic　perspective.　The　identified　causes　are　divided　into　five　categories:　contractors,　management　of　organizations,　technical　methods,　participants,　and　interactive　feedback.　Finally,　safety　recommendations　are　drawn　from　this　study　to　improve　construction　safety　and　safety　management　in　pandemics.
