FIRESTONE, Colo. (CBS4) – At least two people were injured Monday afternoon after a home exploded.

The explosion happened just before 5 p.m.

The home, located along Twilight Avenue, collapsed and burned for several hours after the explosion. At least two were injured.

“It was probably the loudest concussion I’ve ever heard,” said John Anderson, a neighbor to the damaged residence.

Anderson said he was home with his family when he heard the explosion.

“I heard a ‘kaboom.’ The whole house shook,” Anderson said.

When Anderson and his wife Leah ran outside they saw the home was on fire.

“The house was completely collapsed, and people were running up to it,” Leah Anderson said.

Witnesses said a construction crew working nearby quickly responded to the explosion to assist in the rescue of victims.

“I saw a bunch of construction men carrying a human,” said Stephanie Utenick, a medical professional who lives nearby.

Utenick said the men were carrying a woman who had just been pulled from the rubble.

“They took the forklift into the house, lifted the house up, and they pulled her out,” Utenick said.

Those on scene said one of the victims was a mother who was inside the home.

“She has visible burns to her extremities,” Utenick said, describing the woman as a petite and young woman. “Her clothes were burned off in various places.”

Utenick said even though the victim’s arms, legs and chest had burns, she still only had one concern.

“She wanted to know how her children were,” Utenick said.

Neighbors said the boy, who was playing outside at the time of the explosion, was also concerned about his parents.

“He believed his dad was still in the house,” John Anderson said.

Firestone authorities would only say two individuals were transported to the hospital, and would not identify their relation to the incident.

One of the victims was airlifted as emergency response worked to extinguish flames.

While the scene was processed, and investigators searched for a cause, some said their prayers were with the victims.

The quick actions of construction crew was to thank for any survival, Utenick added.

“I told them, ‘You have no idea what you just did. Amazing,'” Utenick said.
