CSB Video on Caribbean Petroleum Explosion - Filling Blind

The U.S. Chemical Safety Board (CSB) has recently  released its vastly informative and interesting new safety video on the 2009 massive explosion at the Caribbean Petroleum, or CAPECO, terminal facility near San Juan, Puerto Rico. 

This incident occurred when gasoline overflowed and sprayed out from a large aboveground storage tank, forming a 107-acre vapor cloud that ignited. 

While there were no fatalities, the explosion damaged approximately 300 nearby homes and businesses and petroleum leaked into the surrounding soil, waterways and wetlands. 

Flames from the explosion could be seen from as far as eight miles away.

Note the re-enactment of this incident as it relates to  monitoring equipment and leak detection.
