Cost-cutting exercises by KiwiRail could end up costing workers their lives if tests on Chinese-made trains show positive results for asbestos, the train drivers' union says.
It comes after 40 of the state-owned company's locomotives were taken out of action following the discovery of the potentially deadly material in a soundproofing compound inside one of the vehicles on Friday.
Initial tests had confirmed the asbestos was contained and not a health risk, KiwiRail chief executive Peter Reidy said. However, further testing will be carried out tomorrow to see if the material had leaked into the air or onto surfaces of any of the trains.
Wayne Butson, general secretary of the Rail and Marine Transport Union (RMTU), said the situation had left many workers fearing for their health and that of their families.
"There's the likelihood that they may either have breathed in asbestos fibres and be susceptible then to what is essentially a death sentence if it materialises in the lungs and triggers mesothelioma, or they may have taken it home in their clothing, put it into the washing machine and therefore any member of the family is at risk as well,'' he said.
