ST. LOUIS -- A broken pipe containing asbestos is blamed for a massive plume of steam in downtown St. Louis Thursday morning; city officials are evaluating several locations for possible exposure.
The 20-inch steam pipe broke beneath North 11th Street, near the America’s Center convention center, around 6:45 a.m. Thursday.
Crews arrived on the scene and were able to turn off the steam supply.
No injuries were reported, but steam could be seen from miles away and the street buckled near the site.
Captain Sutter with the St. Louis Fire Department said 11th Street between Convention Plaza and Lucas Avenue will be closed for at least two weeks so repairs can be performed.
Officials say they have found no evidence of asbestos in the air, but are taking precautions and continuously checking air quality.
Swab samples have found small levels of ground level asbestos, all air quality tests have come back clean.
The City Health Director does advise residents along Lucas Avenue between 11th and Tucker Boulevard to keep windows closed and stay off balconies until cleanup is complete.
