Deadly gas explosions have occurred in Maine, Maryland, and Massachusetts in recent years. A new standard being developed by NFPA aims to address the problem. Angelo kicks off the episode with a story about one recent incident in a small town in Maine, before interviewing the technical committee chair for the new standard, NFPA 715 (6:30), as well as one researcher whose work will heavily inform the document (26:00). Lastly, Derek Vigstol hosts a segment on reconditioned equipment and the NEC (37:45).   Public input on NFPA 715 ends October 15. Go to nfpa.org/715 to submit input and learn more about the standard.
