The plaintiffs represent current and former employees of the county-owned arena. They include electricians and carpenters who worked as independent contractors.

Attorney Joseph Dell told Newsday that 140 people have filed notices of claim, the first step toward filing a lawsuit. He says they’ll name the county, the New York Islanders and facility manager SMG.

The lawsuits will claim they failed to protect them from asbestos exposure throughout the arena.

The lawsuits will likely be consolidated into a class action. They’ll seek between $500 million to $1 billion.
