More than a dozen propane tanks inside a burning South Side home added to the concerns for San Antonio firefighters who responded to the scene to battle the blaze.

Two men who live in the home in the 100 block of Grosvenor Boulevard said the heat of the fire woke them up shortly before 6:30 a.m. Friday.

Firefighters arrived within minutes and began battling the fire.

However, they soon realized the smoke and flames weren’t their biggest threat.

Inside and around the home, firefighters found 16 propane tanks which they said threatened to add unwelcome fuel to the fire.

“We were very cautious because one of those propane bottles could've exploded and done a lot of damage and danger to everybody,” said District Fire Chief Jacob Mendiola. "Luckily they didn't get direct flame exposure. The flames were never hitting the tanks.”

Mendiola said if they hadn’t removed the tanks in time, firefighters may have had to evacuate a number of homes in the area.

The two men who live in the home that burned managed to escape on their own.

One of them -- Gabriel Martinez -- suffered minor burns on his hands and  face while trying to put out the fire initially.

Martinez, who speaks no English, said he thanks God for his safety.

Although the fire gutted his home, he said  what he lost were just “material things that can be replaced.”

Fire investigators believe faulty wiring in a lamp caused  the fire.
