Four Pittsburgh firefighters recently filed a lawsuit against several manufacturers alleging loud sirens on the fire trucks have caused them to suffer hearing loss.

Firefighters Ralph Bilski, Jeremiah Dengler, Roger Maher, III, and Mark Godlewski all have worked as firefighters for the city for years, some as many as three decades. They claim that the sirens have caused irreversible hearing damage and they allege that the trucks were defective in that they lacked sufficient insulation to protect their hearing. Additionally, they claim that the defendant manufacturers, American Lafrance, E-One Inc., Kovatch Mobile Equipment Corp., Mack Trucks Inc., Pierce Manufacturing Inc., Seagrave Fire Apparatus and Federal Signal Corp, failed to provide warnings about their use.
 
The lawsuit does not name the city of Pittsburgh as a defendant.
