M-20.2T TRAINER INFORMATION
Note:
The M-20.2T Trainer is identified by a blue secondary container and a blue scrubber.
WARNING
: The M-20.2T Trainer provides NO protection from hazardous atmospheres and is to
be used for training purposes only.
WARNING:
It is critical that the M-20.2T Trainer be segregated from regular work spaces so it is
not mistaken for an actual M-20.2 EEBD unit.
The M-20.2T Trainer is designed to look like, don like and have breathing resistance similar to the
M-20.2 EEBD.
Opening and donning an M-20.2 EEBD is a motor skill. The most effective method of teaching a motor
skill is to have the student repetitively perform the motor skill.
It is essential that the students have “hands on” experience with the M-20.2T Trainer. The more often
students have the M-20.2T Trainer in their hands and the more often the M-20.2T Trainer is donned in
practice, the better their recall will be. Periodic training is highly recommended to achieve proficiency.
A. The following describes the theory of operation of the M-20.2T Trainer:
1. The M-20.2T Trainer is worn on the belt to demonstrate the proper orientation on the belt or is
placed in the blue Secondary Container to simulate the stored position.
2. The Latch assembly is identical to the M-20.2 EEBD, so that the opening of the M-20.2T Trainer is
practiced “hands on”.
3. As the unit is pulled from the base by the Neck Strap, the Activation Cable Snap disconnects from
the Oxygen Regulator, simulating the oxygen activation of the M-20.2 EEBD.
4. During inhalation, air is supplied to the student from the atmosphere through holes in the
Mouthpiece.
5. During exhalation, air is exhaled into the Mouthpiece, passing through the holes in the Mouthpiece
to the atmosphere. During inhalation and exhalation, the breathing resistance through the
Mouthpiece holes simulates the breathing resistance of the M-20.2 EEBD.
