ENVIRONMENTAL watchdogs have been called in to investigate a new £330,000 ambulance depot after workers began falling ill.

Paramedics at the Scottish Ambulance Service station at Cumbernauld, North Lanarkshire, have suffered breathing problems since moving to the site.

One worker is believed to have left the site and another is on sick leave.

The Scottish Environmental Protection Agency (SEPA) has been called in to monitor dust levels at the depot.

The centre is close to two industrial plants, including a recycling facility.

A source said: "We believe the problem is caused by dust levels. One colleague has left because the doctor told him that his health would be affected if he stayed. Now another member of staff is on sick leave."

Jamie Hepburn, the MSP for Cumbernauld and Kilsyth, said: "I welcome the fact that SEPA are responding to the concerns expressed by Scottish Ambulance Service staff about the impact on them by the adjacent recycling facility.

"Clearly we need recycling facilities of this type, but it is important that they are located sensibly."

The station, home to around 43 staff, was officially opened in April last year. Two emergency ambulances and a paramedic response unit operate from it.

A Scottish Ambulance Service spokesman said: "The welfare of our employees is paramount and following concerns raised by staff we have asked SEPA to look into the dust levels in the area which may be associated with neighbouring businesses.

"We will await the outcome of that process before determining the most appropriate course of action."
