 WARNING:_______THE OXYGEN GENERATOR IS A PYROTECHNIC-ACTIVATED DEVICE. MAKE SURE THE RELEASE PIN OR SAFETY PIN WITH THE WARNING FLAG IS INSTALLED ON THE GENERATOR. IF THE RELEASE PIN OR SAFETY PIN IS REMOVED AND THE GENERATOR FIRES, THE GENERATOR SURFACE TEMPERATURE WILL GET HOT (450 DEGREES F OR MORE). CONTACT WITH A HOT GENERATOR CAN CAUSE INJURY.
 WARNING: MAKE SURE YOU OBEY ALL APPLICABLE REGULATORY REQUIREMENTS
_______ FOR THE TRANSPORT OF OXYGEN GENERATORS. IF THE SERVICE LIFE OF THE GENERATORS HAS EXPIRED, YOU MUST DISCHARGE THE GENERATORS TO MAKE SURE THE OXIDIZER CORE IS EMPTY. THIS MUST BE DONE BEFORE PREPARING THE GENERATORS FOR TRANSPORT. IF THE GENERATORS ARE NOT DISCHARGED AND EMPTY, THEY COULD ACCIDENTALLY DISCHARGE DURING TRANSPORT AND IGNITE A FIRE. THIS COULD CAUSE DEATH OR INJURY TO PERSONS.
 CAUTION: MAKE SURE THAT THE RELEASE PIN IS INSTALLED IN THE LARGER OF
_______ THE TWO HOLES, AND THAT THE SAFETY PIN IS INSTALLED IN THE SMALLER OF THE TWO HOLES IN THE FIRING PIN. FAILURE TO DO SO COULD PREVENT THE OXYGEN GENERATOR FROM CORRECTLY ACTIVATING WHEN OXYGEN MASKS DEPLOY.
 (2)  Visually inspect the firing mechanism to make sure the release pin is correctly installed in the larger of the two holes in the firing pin.
 S 212-112
 (3)  Do these checks to find if the generator fired: (a) If the heat sensitive band on the generator is black, the generator fired. (b) If the firing pin is in the fired position (you cannot install the release pin), the generator has fired.
 S 962-095
 (4)  If the generator has fired, do these tasks: (a) Remove the generator (AMM 35-22-11/401). (b) Install a new generator (AMM 35-22-11/401).

 (5)  If the generator has not been fired, deactivate the generator as follows:
 (a)  
Put the retraction pliers between the release pin and the generator firing pin spring case.

 (b)  
Carefully retract the firing pin by moving the release pin away from the firing pin spring case with the retraction pliers, until the safety pin hole is visible; do not release the pliers.

 (c)  
Put the safety pin into the firing pin's safety pin hole.

 NOTE: The safety pin hole is the smaller of the two holes
____ found in the firing pin.
 NOTE: Make sure the safety pin is between the release pin and
____ the firing pin spring case (Fig. 201).
 (d)  Carefully release and remove the pliers.
