New York City's Transport Workers Union Local 100 is fighting to get to the bottom of health and safety issues, sparking conflicts with the Transit Authority. The latest is at Brownsville Brooklyn where workers are exposed to creosote - a carcinogenic wood preservative. TWU's John Samuelson says Mt. Sinai hospital is testing workers and the union has had to fight the Transit Authority every step of the way.

[John Samuelson 1] : "Transit Authority has been an impediment to us on every time we raise a safety or health concern with the New York City Transit Authority. They're the furthest thing from cooperative. They've wasted tax dollars and energy trying to impede our investigation into creosote effects on workers."

Sameulson says if medical tests show creosote metabolites present in transit workers legal action could result..

[Samuelson 2] : "The medical records will be reviewed and I guess we will be moving first to protect the workers and then to seek a legal remedy for the exposure."
