ANAHEIM HILLS, Calif. (KABC) -- A 17-year-old boy was holding an e-cigarette inside his Anaheim Hills home when it blew to bits. The fragments burned a hole in the wall and carpet. The teenager suffered cuts and burns to his hand.

The incident was the second in two days in Southern California. Cal Fire reported that a Ramona man was rushed to a burn unit after his e-cigarette exploded. It also shattered a window nearby.

The Federal Emergency Management Agency is tracking incidents of electronic cigarette fires and explosions. The data is gathered from media reports.

In a safety study issued four months ago, FEMA reported: "The shape and construction of e-cigarettes can make them more likely than other products with lithium-ion batteries to be-have like 'flaming rockets' when a battery fails."

According to the FEMA, 25 injuries have been reported between 2009 and October 2014.
