Changing The Protective Elements; Taking The Equipment Off - Sundstrom SR 200 A irline Instrucciones De Uso

Chemical Cartridges
Each chemical cartridge is designed to provide re-
spiratory protection against specific contaminants. A
chemical cartridge absorbs and/or adsorbs specific
vapors and gases from a contaminated atmosphere.
This process continues until the sorbent becomes
saturated and allows the contaminant to break through.
OSHA requires a chemical cartridge change out
schedule based on workplace aerosol concentration
and no longer relies on breakthrough sensory detection
to initiate chemical cartridge changing.
Particulate filters
Filters provide protection against particulates. All
Sundström particulate filters trap and hold particles in
the filtering media. As the amount of the captured con-
taminant in the media increases, breathing resistance
also increases. Replace the filter when the change in
breathing resistance becomes noticeable.
The P100 filter is 99.97% efficient against all particulate
aerosols.
Sundström Safety has conducted degradation testing
of our P100 filter. Our test results show that even after
an extensive period exposed to oil based contaminants
this filter will not degrade.
Combination Protective Elements
An appropriate chemical cartridge and P100 filter can
be combined to provide protection from a combination
of certain vapors, gases and particulates.

2.4.2 Changing the protective elements

A. Installation / removal
Select the appropriate protection. Remain in a safe
atmosphere and select the proper cartridge and ap-
propriate filter.
Assembling the cartridge, P100 filter combination.
Fig. 2
• Place the P100 filter on top of the cartridge. Grasp
both protective elements.
• Squeeze hard until you hear the P100 snap onto
the cartridge.
• Pull on the filter and cartridge to check that they
are properly connected.
• Snap the sealing cover onto the filter.
• Check to see that it is firmly attached to the cartridge
or filter.
Installing the protective element into the respirator.
• Hold the protective element in your hand with the
arrows on the label pointing toward the face. Insert
one part of the large lip of the protective element
into the filter adapter flange.
• Grab the flange with your finger and pull the lip of
the adapter flange around the protective element
until the entire protective element is seated inside
the filter adapter.
• Squeeze the top edge of the protective element
and the bottom edge of the respirator filter adapter
together until the filter adapter flange is seated
against the edge of the cartridge.
• Make sure that the gasket in the respirator con-
nector is in place, screw the filter adapter with the
protective element onto the respirator connector.
Carefully tighten the filter adapter by hand to prevent
damage to the thread and to ensure a good seal
against the gasket.
B. Removing the protective elements from the res-
pirator.
• Screw off the filter adapter with the protective ele-
ment from the respirator connector.
• On the top of the respirator filter adapter flange is
a small tab that touches the side of the protective
element.
• Grasp the protective element with one hand and this
tab with the finger and thumb of the other hand.
• Peel back on the tab while pulling on the car-
tridge.
If you are using a stacked cartridge and filter, you must
now remove the filter from the cartridge.
Take a coin, or similar item, and place it in the space
between the lower lip on the P100 Filter and the small
raised plastic tab on the side of the cartridge. Twist the
coin until the filter pops off the cartridge. Fig. 3.

2.5 Taking the equipment off

1. When using a back-up filter
• Remove the sealing cover, if fitted.
• Disconnect the compressed air hose from the
regulator. See below.
• Leave the polluted work area and take the equip-
ment off.
• Slacken the four elastic straps in pairs by moving
the strap holders forward. Fig 9. The two inelastic
straps need not be released.
• Pull the head harness forward over your head and
remove the mask.
2. When using the sealing plug
• Leave the polluted work area and then take the
equipment off. See below for details of releasing
the hoses.
• Slacken the four elastic straps in pairs by moving
the strap holders forward. Fig. 9. The two inelastic
straps need not be released.
• Pull the head harness forward over your head and
remove the mask.
Releasing the air supply hoses:
CEJN connectors
Push the coupling towards the nipple, at the same time
pulling the locking ring back. Fig. 10.
Schrader and Hansen connectors
Twist the locking ring on the coupling.
