HOUSTON (FOX 26) - The fire at the Holmes recycling center at 2820 Holmes Road broke out around 4:20 p.m. Wednesday.
The immediate concern for firefighters was any chemicals burning. The hazmat team was called in and began testing the air and water.
"The air seems to be in expected ranges for a fire," said HFD fire captain Ruy Lozano. "We really want the public to know there's no need to panic."
The blaze sent huge plumes of smoke for miles and a pungent smell. Anyone smelling it should not be concerned, said fire officials.
Burning metal was the reason for all the plumes of smoke and foul odor. That's also why firefighters were expected to remain at the fire scene for several more hours.
No injuries were reported. A firefighter was checked out at the scene for smoke inhalation.
The cause of the blaze remains under investigation.
