Keep out zone system

Various hard hat fan systems are provided. In a certain embodiment, fan system includes an impact absorbing layer with a channel that defines a recessed surface which extends into the impact absorbing layer away from an inner surface of a shell of a hard hat. Together, the inner surface of the shell and the recessed surface define a duct configured to provide fluid communication between an inlet of the channel and an air vent positioned along the channel. In another embodiment, fan system includes a mounting bracket with first and second cam levers which may be actuated into a locked position, and first and second channels. When in the locked position, the first and second cam levers bias the edges of a mounting ridge of the shell against the first and second channels of the mounting bracket such that the mounting bracket is retained on the shell.

Various face shield assemblies for hard hats are described. In one embodiment, the face shield assembly includes a hard hat, a mounting bracket, a face shield, a first pivot arm and a second pivot arm. The first pivot arm and second pivot arm are pivotally coupled to the hard hat and rotate with respect to the mounting bracket and the face shield. The face shield is coupled to the first pivot arm and the second pivot arm. The face shield actuates between stowed and operating positions such that the face shield can avoid objects near a front of the hard hat, such as a bill and/or lamp. In other embodiments the face shield assembly includes an adjustable frame coupled to the face shield and the hard hat. The adjustable frame rotates and/or slides with respect to the hard hat.
