An effect is prioritized over an unexplained fault

A fictional rehearsal uses fog and a compressed-gas effect near a stage pit. The team has not completed the actual ventilation assessment, emergency-access check or authorized coordination with the venue’s alarm arrangements. An electrical protective device trips repeatedly, and someone suggests bypassing it so rehearsal can continue. A manager argues that the event has a safety officer, so no other contractor needs to check its own work. No effect or electrical operation occurs in this case. Identify the interacting hazards, unsupported assumptions and controlled decisions needed before work continues, without inventing a universal sound level, gas concentration, alarm-isolation procedure or authority to modify equipment.
