Water rescue gear for firefighters in Kingsway
Derbyshire Fire and Rescue Service has new water and flood rescue equipment.
It will be carried in a dedicated vehicle and there is also a six-person power boat designed for open water.
Kingsway fire station is the first in the county to have the equipment and all its crews have been trained in water rescue.
Station manager Steve Ratcliffe said open water could be very dangerous for people tempted to cool off during the summer holidays.
"While open water always looks inviting, especially when the sun is shining, these areas are extremely dangerous even for strong swimmers."
Derbyshire Fire and Rescue Service is currently training more staff in water rescue so the whole county will be covered.
