Clifford Law Firm filed three lawsuits following the Des Plaines gas explosion that injured 18 people in the Chicago suburbs. The May 6 explosion damaged a condominium building near O’Hare International Airport and triggered several injury claims against NICOR Gas and property manager Tom Dase Management LLC.

Des Plaines explosion sparked massive emergency response
Residents escape through windows during fire
Witnesses described a chaotic scene after the explosion ripped through the three-story condominium complex.
Some residents reportedly jumped out of windows before firefighters arrived. Emergency crews then used ladders to rescue trapped occupants as smoke and flames spread through the structure.
As a result, local authorities evacuated nearby residents while firefighters worked to contain the fire.
Reports indicate that eight victims, including four children, remained hospitalized after the explosion. Several victims are said to be in critical condition.
Additionally, the American Red Cross assisted displaced families after the explosion left many residents without housing.
Clifford Law Offices Leads Litigation Efforts
Bradley Cosgrove represents injured victims
Bradley M. Cosgrove, a partner at Clifford Law Offices, is leading the litigation efforts on behalf of several injured residents.
Cosgrove said the prosecution was aimed at preserving evidence and discovering the cause of the explosion. He also described the explosion as a tragedy that deeply affected the surrounding community.
The lawsuits claim residents warned authorities about the smell of natural gas before the explosion occurred. Therefore, attorneys will likely focus on maintenance records, inspection reports, emergency response times, and prior tenant complaints.
Legal analysts expect the litigation to involve extensive forensic investigations and expert testimony.
NICOR gas and property managers face scrutiny
Utility negligence claims could grow
Gas explosion lawsuits often turn into complex legal battles involving multiple defendants and technical evidence.
In this case, attorneys can examine whether NICOR Gas properly investigated reports of gas odors before the explosion. Lawyers could also check whether the property management company followed safety protocols and maintenance requirements.
Additionally, litigation may determine whether building safety warnings were ignored or improperly addressed.
Utility negligence cases frequently trigger aggressive discovery litigation because plaintiffs and defendants often rely on competing engineering experts. Therefore, early preservation of evidence can significantly affect the outcome of litigation.
Legal professionals say catastrophic explosion cases can expose companies to significant financial liability, especially when multiple victims suffer serious injuries.
Illinois explosion litigation continues to grow
Catastrophic injury cases remain a major area of practice
Explosion and fire litigation remains an important practice area for plaintiff firms across the United States.
Law firms handling catastrophic injury claims often respond quickly after large-scale disasters. Immediate investigations can help attorneys obtain witness statements, preserve physical evidence, and coordinate with engineering experts.
As a result, many firms are investing heavily in rapid-response litigation teams for high-profile cases involving utilities, transportation companies and landowners.
Legal recruiters also note that attorneys with trial experience, forensic investigative skills and a track record of mass torts remain in high demand.
