The components of the M-20.2 EEBD are: (see illustration on next page)
(1) Nose Clip - the yellow nose clip is permanently attached to the mouthpiece.
(2) Mouthpiece - the yellow mouthpiece is placed in the mouth such that the flange seals between the lips
and gums. The bits should be between the upper and lower teeth. Gently bite on the bits.
(3) Neck Strap - the yellow neck strap is be placed over the head for support and can be adjusted for fit.
(4) Oxygen Cylinder - the stainless steel cylinder holds 100% medical grade oxygen.
(5) Oxygen Regulator - starts the flow of oxygen and increases the oxygen flow during high work rates.
(6) Activation Cable - the stainless steel activation cable is attached to the oxygen regulator and
permanently attached to the inside of the base.
(7) Gauge - indicates the amount of oxygen in the cylinder. The green zone indicates the M-20.2 EEBD is
ready for use. The red zone indicates the cylinder is low on oxygen and should be removed from
service. The gauge is visible through the clear case and the orange secondary container.
(8) Scrubber - a chamber containing lithium hydroxide that removes carbon dioxide from the exhaled air.
(9) Breathing Bag - air reservoir that receives oxygen from the regulator and exhaled air from the user.
(10) Relief Valve - a one way valve that automatically allows excess air in the breathing bag to vent.
(11) Yellow Lever - the yellow lever is lifted upwards to open the M-20.2 EEBD.
(12) Cover - may have optional overcase pads, a user replaceable item that provides increased abrasion and
impact resistance.
(13) Base - if belt worn, the base stays on the belt after the M-20.2 EEBD has been removed from the case.
The base has an overcase pad that provides increased abrasion and impact resistance.
(14) S-Hook - the metal hook that receives the cover latch on the belt side.
(15) Face Shield - in the event the user requires head protection from smoke or chemical vapor, the face
shield may be pulled up over the head and secured around the neck by pulling outward on the draw
strings. This should be done only after inserting the mouthpiece and applying the nose clips. The Face
Shield is not part of the breathing circuit and is not required for respiratory protection.
(16) Bag Shield - a cover over the breathing bag providing additional protection to the breathing bag.
(17) Tamper Indicating Ball - the presence of a stainless steel ball bearing located in the center of the
yellow lever assures that the unit has not been opened.
(18) Band Label - user completed label indicating date of belt worn service.
(19) Information Label - contains the following information:
•MFG DATE XX/XX, the date of manufacture as month/year
•LIFE DATE XX/XX, the end of service life date as month/year
