Heat safety: Stories meant to help protect New York’s Very Own

Explosion destroys NJ home; nearby high school damaged

HARDYSTON, N.J. — An explosion in New Jersey left a house "at a total loss," officials said, reducing the home to rubble.

Authorities received a call just before 11 p.m. Tuesday about an explosion at 33 Grumm Rd. in Hardyston.

There were no occupants inside the home at the time of the explosion, according to the Hardyston Township Volunteer Fire Department.

The house had been vacant for the last couple of months and that propane was the only gas available on the block, said Dave Hook, the home's developer.

"Propane [is the] only gas being available on Grumm Road. However a mere 1,000 feet away is a main natural gas line. However they never made it available down Grumm," he said.

No injuries were reported, authorities said.

A spokesperson for Elizabethtown Gas told PIX11 they have no indication the incident was a natural gas-related event.

"Of course, the safety of all those in the communities we serve is our highest priority, and out of an abundance of caution, our Elizabethtown Gas crews are verifying the integrity of any infrastructure we may have in the surrounding area."

A neighboring house had window damage following the explosion, the fire department said.

Wallkill Valley Regional High School, located nearby the house, also had structural damage and will be closed for the day, said authorities. The extent of the damage was not immediately known.

Grumm Road will be closed indefinitely. The cause of the explosion remains under investigation.


Residents in northern New Jersey took to social media, describing the explosion's sound as "thunder," others saying their homes shook.
