The Los Alfaques disaster was an explosion that took place near a campsite in Tarragona, Spain, when a leaking tanker truck loaded with 23 tons of highly flammable liquid propylene ignited.

It killed 217 people, including the truck’s driver, and severely burned more than 200. What regulations were later instituted to prevent future disasters of this sort? Discuss
