When opening the passenger cabin door, the emergency slide accidentally deployed

This is the kind of mishap that happened to a flight attendant of this JetSmart Airbus A320 at Santiago Airport (Chile).

When opening the passenger cabin door, the emergency slide accidentally deployed. 🤷‍♂️

To prevent such situations, flight attendants always perform a cross-check before opening doors, with each crew member verifying the actions of their colleague to ensure that the automatic deployment of emergency slides is indeed disabled.
