Changing The Protective Elements; Inspection Prior To Use; Donning/Fit Check/Doffing - Sundstrom SR 200 Instrucciones De Uso

If you smell, feel or taste anything unusual leave
the contaminated area, check your respirator, and
replace the protective element if necessary. In some
atmospheres breakthrough may be hard to detect
or may occur too late to provide you a safe exit
from the contaminated atmosphere. An air-purifying
respirator is not appropriate for use. However under
certain conditions, the chemical cartridges can be
used but must be changed after a specific exposure
time. This schedule is set by a competent authority
and controlled by your safety professional.
WARNING
Warning. An exhausted chemical cartridge
will allow hazardous fumes or vapors to pass
through to the user who may not notice any
change in breathing resistance. Follow local
procedures and all warnings contained in the
users manual.
Filters – Filters clean the air of particles by capturing the
solid particles and allowing breathable air to enter the
respirator. As the filter loads up with these particulates
inhalation becomes uncomfortable. When you detect
increased inhalation resistance, leave the contaminated
area and change the pre-filter, or if necessary, the
protective filter.
Time use restrictions may also apply to some filters
when efficiency declines or when they are exposed to
specific contaminants. Filters must be replaced every
time these limits are reached.
Pre-filter – This inexpensive nuisance pre-filter is used
with a cartridge or P100 filter. When breathing resistance
increases change the pre-filter first. If the resistance
does not drop change the protective element.

1. 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.
B. Assembling the cartridge, P100 filter combi-
nation. 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.
• Place a pre-filter into the pre-filter holder.
8
• Snap the pre-filter holder 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 towards the face. Insert
one part of the large lip of the 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 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 connector
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.
C. Removing the protective
elements from the respirator.
• Screw off the filter adapter with the protective element
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 cartridge.
• 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. Inpection prior to use
Before donning the respirator always perform
the following checks.
• Ensure that the respirator is clean and dry.
• Check the respirator, valves, harness and visor for
cracks, missing parts, and other defects.
• Check that the appropriate chemical cartridge, filter
or combination is installed properly.

3. Donning/Fit check/Doffing

A. Donning
• Remove any hood, glasses or ear protection from
head.
