What happened

A fire broke out before closing time at the Alcalá 20 nightclub in Madrid. Contemporary reporting described synthetic curtains and plastic fittings catching fire, toxic fumes, panic, crowd pressure toward exits, and allegations that emergency exits were blocked or poorly marked. Later Spanish reporting states that lack of safety measures and padlocked emergency exits led to an overhaul of safety protocols in Spain. (The Washington Post)
