Tri-Lock BG/BF bag-in/bag-out contamination
filter housings are designed to protect
facility personnel and the general public
from dangerous materials by filtering those
materials. The filters that you are to change
contain the filtered material. In order for you
to be protected as fully as possible, you must
follow these instructions as amended by
your chief safety officer. The bagging
method of changing a filter is not foolproof,
but it is the safest practical method available
for changing contaminated filters.
We realize that a single manual cannot
address all types of housing designs and
configurations, so we are offering the
concepts of installing a new filter(s) into a
new system and replacing dirty filters in
systems that are already in operation. Once
the concept is understood, both maintenance
personnel and safety personnel can adapt
the most suitable method to use considering
the housing, location, type of filter, and any
other items that can affect safety.
Carefully study this manual and the safety
officer’s amendments so that you have the
entire procedure in mind before attempting
filter change out. Be sure to have all tools
and equipment on hand prior to actually
beginning work. In this manual, we describe
the Tri-Dim Filter Corporation banding
method of sealing the bag.
The important thing to remember is to use
this manual, your safety officer’s instructions,
and your own reasoning ability to prevent
yourself and the immediate environment
from being contaminated with the material
that is captured on the dirty filter.
