A barrier device (1) that stores a flexible barrier (2) wrapped around a shaft (3) is disclosed. The barrier (2) may be unwound to cover an area with only the barrier (2) inside that area. The device (1) consists of the barrier which is formed from sheet material, at least one anchor point (9c), a storage device for storing the barrier (2), and a line (6). The storage device includes the shaft (3) around which the barrier (2) is wrapped when in a stored position. The storage device is also positioned substantially outside the area the barrier (2) occupies while in an operational or un-stored position. A driving mechanism (4) is attached to the shaft (3) of the storage device which causes the shaft (3) to rotate, transferring the barrier (2) between the stored position and the operational position. The line (6) is attached between an attachment point (7c), on the opposite side of the barrier (2) to the shaft (3), and the driving mechanism (4) via an anchor point (9c). A biasing device (8) is mounted to the anchor point (9) and maintains the line (6) in a tensioned state. The biasing device (8) includes at least one pulley (10) through which the line (6) passes, and a spring (11) configured to bias the at least one pulley (10). The spring (11) is positioned substantially outside the area the barrier (2) occupies while in an operational position.
