A hazardous materials incident on the South Side of Chicago ended up secured after a gas main break Thursday morning forced an evacuation, officials said.
Construction crews hit the high pressure gas main break in the 600-block of East 91st Place in the Chatham neighborhood around 6:45 a.m.
The break prompted a Level 2 HazMat response, the Chicago Fire Department said.
A Level 2 response is an incident involving hazardous materials that is beyond the capabilities of the first responders on the scene and could be beyond the capabilities of the public sector responders having jurisdiction. Level 2 incidents might require the services of a state or regional response team or other state or federal assistance. This level can pose immediate and long-term risk to the environment and public health, according to the National Fire Protection Association (NFPA).
The Chicago Fire Department evacuated homes as a precaution and a nearby school was put on lockdown to shelter-in-place.
The HazMat incident was secured by 10:30 a.m. and no injuries were reported.
