The duct can have a releasable connector configured to releasably connect the duct to a brim of a safety helmet shell.

Abstract: A screwdriver device including a handle having an elongate channel extending partially therethrough of the handle and an axial blade member having a first distal end and a second distal end being configured and disposed for sliding through the elongate channel of the handle and a locking mechanism configured and disposed for releasably locking the axial blade member at a first operable position relative to the handle wherein the first distal end is exposed and the second distal end is disposed within the handle. The screwdriver device further includes a first tool head disposed on the first distal end of the blade member and an ejection mechanism configured and disposed within the handle to constantly urge the axial blade member out of the locking mechanism from the first operable position to a second inoperable position.

Abstract: A nut driver includes an elongate drive shank and a reversible socket. The socket has a first hex socket opening sized to engage a hexagonal profile of a first size, and a second hex socket opening sized to engage a hexagonal profile of a second size that is larger than the first size. The socket is mountable on the drive shank in either a first orientation that presents the first hex socket opening for use, or a second orientation that presents the second hex socket opening for use. Additionally, in the first orientation, the socket is mountable in either a screw head receiving position or a drive bit receiving position.
