Head Harness Adjustment and Donning the Butyl Hood
Note:
If possible, the ‘buddy system’ should be utilized to aide in effective and fast donning of the system. A second
person can help the wearer by insuring that the head harness is adjusted and donned properly, and to check proper
positioning of the hose and hood skirt.
Don the blower and hood in a safe hazard-free area and accomplish the following:
•
Confirm that the three cartridges are properly mounted on the blower unit.
•
Adjust the hood’s head strap according to your head size making adjustments to ensure a comfortable/stable fit.
•
Initial sizing is based upon head circumference, although other factors including the subject’s head shape,
forehead size and shape, and hair will affect the sizing of the product.

HEAD HARNESS SIZING INSTRUCTIONS
Remove the protective wrap from the head
harness and discard.
The Sentinel XL CBRN head harness is packaged
pre-sized to the XXL head adjustment. To adjust
the head harness to different size, unsnap the female
end and move the female adjustment snap to the
proper male location and fasten into place. If the
user is sizing for small or XS this will cause the hood
slot material to bunch.
