PRESENTATION (STEP 2) INSTRUCTOR NOTES

II. Donning SCBA From the Ground

A. Crouches or kneels at the end opposite the cylinder

valve

B. Checks the air cylinder gauge to ensure that the

cylinder is full

C. Opens the cylinder valve slowly and listens for theaudible alarm as the system pressurizes

D. Fully opens the cylinder valve after the alarm

sounds

- If the audible alarm does not sound, or if it

sounds but does not stop, place the unit out

of service by tagging it and notifying an

officer; use another unit

E. Check the regulator gauge and cylinder gauge

pressure to ensure that they read within 100 psi of

the same pressure

F. Spreads the harness straps out to their respective

sides

G. Grasps the back plate or cylinder with both hands,

one at each side, making sure that the cylinder valve

is pointed away from them

H. Lifts the cylinder, letting the regulator and harness

hang freely

I. Raises the cylinder overhead, letting the elbows

find the respective loosened harness shoulder strap

loops

J. Grasps the shoulder straps as the SCBA begins to

slide down the back

K. Lets the straps slide through the hands as the

backpack lowers into place

L. Leans forward to balance the cylinder on the back

and then fastens the chest buckle if the unit has achest strap

M. Continues leaning forward and tightens the shoulder

straps by pulling them outward and downward.

(NOTE: It is sometimes necessary to lean forwardwith a quick jumping motion to properly position

the SCBA on the back while tightening the straps)

N. Fastens and adjusts the waist strap until the unit fits

snugly

O. If the facepiece harness is a web-type, grasps the

harness with their thumbs through the straps from

the inside, and spreads the straps

P. Pushes the top of the harness up their forehead

to remove hair that may be present between

the forehead and the sealing surface of the

facepiece

Q. Center the chin in the chin cup and position

the facepiece harness so it is centered at the

rear of the head

R. Tightens the harness straps by pulling them

evenly and simultaneously to the rear the

lower straps first

S. Repeats R with the temple straps

T. Repeats R with the top straps

U. Checks the facepiece seal by exhaling deeply,

sealing the end of the low-pressure hose with

your bare hand, and inhaling slowly (not

deeply), holding their breath for 10 seconds.(NOTE: Inhaling very quickly will

temporarily seal any leak and will give a false

sense of a proper seal)

1. If there is evidence of leaking, adjustor re-don the facepiece

V. Checks the exhalation valve by inhaling while

sealing the end of the low-pressure hose with

the palm of their hand, and then exhaling

1. If the exhalation escapes at the edges

of the facepiece and does not go

through the exhalation valve, keep the

low-pressure hose sealed, press the

facepiece against your face, and

exhale to free the valve

2. Use caution when exhaling against a

sealed facepiece in order to prevent

discomfort and possible damage to the

inner ear from exhaling forcefully

facepiece and does not go through the

exhalation valve, keep the low-pressure

hose sealed, press the facepiece against

your face, and exhale to free the valve

2. Use caution when exhaling against a sealed

facepiece in order to prevent discomfort

and possible damage to the inner ear from

W. Connects the low-pressure hose to the regulator. If

the unit has a donning switch, turn it to the

PRESSURE, USE or ON position. If the unit does

not have a donning switch, open the mainline valve

X. Checks for positive pressure by gently breaking the

facepiece seal by inserting two fingers under the

edge of the facepiece
