4-Alarm Fire Ravages West Houston Warehouse Complex

Explosions rocked a warehouse complex earlier today.

— -- A four-alarm fire at a warehouse complex in the Texas city of Spring Branch, located in the northwest Houston area, sent roaring flames and long plumes of black smoke into the sky, as canisters of hazardous materials exploded loudly throughout the morning.

The blaze started at a nearby house fire before spreading to the warehouse complex. It is unknown what caused the initial fire and arson investigators are investigating. The warehouse is used by a custom packaging company. Several other businesses were part of the complex as well.

Nearly 200 firefighters have been deployed to put out the blaze, according to ABC's Houston affiliate KTRK.

A resident of the area told KTRK that the explosions shook the foundation of her home.

The warehouse complex is situated near several schools, including Spring Ranch Elementary, which was evacuated. A hazmat team is on site to determine if any hazardous chemicals have been released into the air as a result of the blaze.

No one has been injured or killed in the fire, which the Houston Fire Department has said is now under control.
