VICE PROCEDURES
CARE OF FIBERGLASS BOOMS
BOOM CLEANING RECOMMENDATIONS
Fiberglass booms and inserts must be kept clean
and in good condition to preserve their dielectric
properties and appearance.
1. The fi berglass outer surface of the boom should
be cleaned daily with a lint free cloth.
2. DO NOT Steam Clean Any Fiberglass or
Insulated Components.
3. When the boom is dirty, raise the boom slightly,
so it will drain, and wash the boom with a mild
dish-washing detergent, using a cloth or sponge.
Once the boom is washed inside and out, wipe
the outer boom clean and dry with a lint-free cloth
and allow the inner boom to air-dry completely.
4. In extremely difficult cleaning situations,
pressure washing (using a garden hose and
nozzle) can be used to clean the fi berglass
boom. CAUTION: If the water pressure is too
high, the boom, hoses, and fi ttings could be
damaged.
5. If the boom has creosote, grease or other
deposits that cannot be removed as suggested
above, stronger cleaners may be used.
However, be sure that these cleaners are not
either 1) abrasive because they may damage
the boom surface or 2) some other type that
may leave a conductive residue on the boom.
Time Manufacturing suggests Donar Chemicals
“Electra Clean” and Costa Chemicals “Formula
Five” as an acceptable product for the cleaning
of these fiberglass booms. When heavily
soiled booms are cleaned, make sure they
are thoroughly rinsed and allowed to air dry as
described in Item 3.
6. Once the fi berglass boom is clean, it should
be coated with a product designed to protect
its surface. A good wax designed for use on
fi berglass not only protects the boom’s glossy
surface, but also provides a barrier against
dirt, creosote, etc. Hasting Fiberglass Product,
Inc., Costa Chemicals and Kearney offer a
waxes designed for use on fi berglass. Donar
Chemicals also offer a product called “Electra
Guard”, for use on fi berglass. For best results,
fi berglass booms should be polished by hand.
7. After a boom is cleaned and dried, it should be
dielectrically tested in accordance with ANSI
Standards (Section 5.4.3) to verify its dielectric
integrity and to detect conductivity changes in
its insulating section.
8. Fiberglass booms and inserts should always be
cleaned before any dielectric test. Remember
that cleaning and testing is required after repair
or modifi cation of any component that crosses
the insulating system(s) or the repair or
replacement of an insulating component(s).
9. If fi berglass accessories such as line-hose boxes
or saw scabbards are attached to the boom, they
should be removed during dielectric testing of the
unit. They should also be washed and cleaned
on a regular basis because they could reduce
the dielectric integrity of the boom. Care should
be exercised in the selection and placement of
such accessories to ensure that the insulation
is not compromised.
10. If, while inspecting or cleaning the boom, you
discover chips, scrapes or abrasions that would
allow moisture to get into the fi berglass boom,
it should be recoated or sealed in accordance
with manufacturer’s recommendations. Any
time there is a doubt regarding damage to
the fi berglass booms or inserts, contact
Time
Manufacturing Company before any repairs
are done.
