Plaintiff lawyers have made New Jersey the latest front for litigation by firefighters over alleged hearing loss from long-term exposure to sirens.

According to a suit removed to federal court in Newark on Dec. 4 the pitch and decibel on fire truck sirens made by Federal Signal Corp. are unreasonably dangerous to firefighters.. Five fire truck manufacturers are also named in the suit, which was filed on behalf of 34 current and former firefighters.

The law firms that filed the New Jersey suit also brought 20 suits against the same defendants on behalf of 193 Buffalo, New York, firefighters in October 2014. Those cases are still pending in the Western District of New York.
