Summary
A pressure-test near miss involved an incompatible dummy hot stab ejecting from its receptacle while personnel stood nearby but outside the direct line of fire. The flash identifies missing retention, undocumented work controls and inadequate barriers, and recommends secure compatible fittings, safe-distance exclusion zones and depressurisation before investigating leaks.
