(1) Grasp injector set with your nondominant hand by the plastic clip with
the big autoinjector (2-PAM Cl) on top in front of your body at eye level where you can
see it (figure 8-5 A). This will make it easier to remove the injectors from the clip without
(2) Grasp the atropine (small) autoinjector with the thumb and two fingers of
the other hand without covering or holding the needle (green) end of the autoinjector
(figure 8-5 B). Putting pressure on the green end could cause the autoinjector to
function prematurely during removal.
Pull the injector out of the clip with a smooth motion (figure 8-5 C).
The injector is now armed. Take care to not press the green (needle)
end until the autoinjector is pressed against your thigh.
Figure 8-5. Removing the atropine autoinjector from the MARK I clip.
(4) Form a fist around the atropine autoinjector with the needle end (green)
extending beyond the little finger end of the fist. Be careful not to inject yourself in the
hand. This will not give you a fully effective dose of the antidote. If you should
accidentally inject yourself in the hand, you need to obtain another atropine autoinjector
and use it to inject yourself in the thigh/buttock.
(5) Make sure the injection site is cleared of any objects that could interfere
with the injection. If the injection site is in the thigh, grasp the trouser cargo pocket with
your nondominant hand and pull forward, clearing possible obstructions from the site. If
you are going to give the injection in your buttock, lift the flap of your jacket if it is
covering the injection site. Avoid the mask carrier, straps, buttons, or other possible
(6) Place the green (needle) end of the atropine autoinjector against the
selected injection site at a 90 angle.
