Mich. Admin. Code R. 408.13345 - Headgear
Rule 3345.
(1)
A headgear shall consist of at least a headband and a crown strap. The headgear
shall be made from materials having a low heat conductivity. The design shall
hold the window and window support comfortably and firmly in place on the
wearer's head and shall provide for tilting the window away from the
face.
(2) A headgear shall be
readily adjustable to head sizes from 6 1/2 to 7 5/8 without the use of tools.
The crown strap or band shall be attached to and extend between the front and
rear centers or from the middle sides of the headband. It shall form an arc
over the head to assist in positioning and holding the headgear in place. An
adjusting device shall be positive and hold firmly in place after being
adjusted. Its mechanisms and movements shall be protected so that the wearer's
hair cannot catch in the device.
(3) For greater protection, a headgear may be
replaced by an impact-resistant hat or cap to which the window support is
connected. The attachment may be either rigid or swiveled. If swiveled, the
design shall permit lifting and adjusting the window to permit unobstructed
vision or lowering to furnish protection.
