Officials are investigating whether fireworks are behind a blaze that destroyed about 350 portable toilets outside San Antonio.
The San Antonio Express-News reports that Bexar County spokeswoman Monica Ramos said the blaze started about 10:30 p.m. Tuesday at United Site Services, east of the city center.
Ramos said the cause of the fire is unknown and that it is still under investigation.
Other officials, however, say fireworks may have started a grass fire that eventually spread to the business, reaching the portable toilets.
United's website says that, with 52 locations nationwide, it is the largest provider of portable toilets and restroom trailers in the country.
