The men loosen their collars, ties, and belts and then stand or sit as
instructed with their hats in their hands. The procedure described below
and illustrated in figure 5-7 should be followed. The operator may remain
in one position and have the subject turn as required or the operator may
move around the subject. At least two full, even strokes of the plunger are
required each time the hand duster is pointed in different directions.
(1) Head . First, dust the subject's head. Have the person rub the
powder into his hair until it is whitened. Then dust his hat.
(2) Right arm . Have the subject stretch his right arm out to the side at
shoulder height, insert the nozzle of the duster into the sleeve next to the skin, and
direct the flow of powder toward the armpit. Hold the trigger on the duster down until
powder is seen coming from the loosened neck of the shirt. The subject's face should
be turned away from the side being dusted.
(3) Left arm . Dust the left arm using the same procedures as were used for
the right arm.
(4) Neck . Insert the nozzle inside the shirt collar at the back next to the
skin. Blow powder toward the right side, toward the waistline, and then toward the left
side. Be sure that some powder is dusted on the collar where lice are likely to hide.
This can be done most effectively with the operator standing in front of the subject and
the subject resting his chin on his chest.
(5) Chest . Insert the nozzle inside the shirt collar at the front next to the
skin. Blow powder toward the right armpit, toward the waistline, and then toward the left
armpit. The subject should lean forward with his head tipped backward.
(6) Groin and legs. With the subject standing, insert the nozzle inside the
top of his loosened drawers at front next to the skin. Blow powder toward the right leg,
toward the crotch, and then toward the left leg.
(7) Buttocks and legs . Insert the nozzle inside the top of the loosened
drawers at the back next to the skin. Blow powder toward the right leg, toward the
buttocks, and then toward the left leg.
