Gas explosion in Mexico caused by worn bolts on gas truck

MEXICO CITY (AP) — Mexican officials said Monday that two worn-out bolts on a gas tanker truck broke, causing a leak that resulted in a hospital explosion that killed five people last month.
The results of the investigation again highlighted the unsafe conditions that many propane tankers operate under.
The failure "was caused by (metal) fatigue on the bolts due to a lack of proper maintenance," said Mexico City chief prosecutor Rodolfo Rios.
When the two bolts on a pipe flange connected to the truck's pump cracked, a gasket partially blew out, allowing gas to accumulate on the hospital grounds for about 25 minutes.
