Never stow chlorinated-cleaning solvents near heat
sources or open flames. Do not allow them to come in
contact with hot surfaces. Make sure stowage areas are
well ventilated and monitored regularly by the gas-free
engineer. Additionally, do not stow these solvents near
incompatible materials. Incompatible materials include
strong alkalies, such as sodium hydroxide; oxidizers,
such as calcium hypochlorite and sodium nitrate; and
powdered metals, such as aluminum.
When handling chlorinated-cleaning solvents, wear
the following personal protective equipment (PPE):
Safety goggles that will protect against splashes
or a face shield
A chemical cartridge respirator for protection
against small amounts of organic vapors or for
protection for a short duration; or an air line respirator
(or some other type of supplied-air respirator) if use is
extensive or in a confined space
Make sure work areas in which you use
chlorinated-cleaning solvents have proper ventilation.
For enclosed spaces, an air change every 3 minutes is
recommended. Consult the gas-free engineer to
determine if the ventilation is adequate.
Organic-cleaning solvents include toluene, xylene,
some alcohols, acetone, methyl ethyl ketone, ethyl
acetate, dry-cleaning solvent (PD-680, Type II),
kerosene, petroleum, ether, turpentine, morpholine,
and other related compounds. These compounds are
highly flammable and moderately to highly toxic.
Some also cause corrosion. Inhalation of concentrated
vapors may cause dizziness, nausea, or vomiting.
Stow organic-cleaning solvents in a flammable
liquid storeroom, or flammable liquid lockers,
according to OPNAVINST 5100.19 (Series), Chapter
C23, Appendix C23-C. Keep the solvents away from
heat, open flames, or spark-producing devices. Stow
them away from oxidizers, such as calcium
hypochlorite, sodium nitrate, and hydrogen peroxide.
When handling organic-cleaning solvents, wear
the following PPE:
Safety splash goggles
In addition, if vapors accumulate over 100 parts
per million (ppm), wear an oxygen-breathing
apparatus (OBA) and notify the gas-free engineer.
DISPOSAL OF HAZARDOUS MATERIAL.
When it becomes necessary to dispose of any
hazardous material, it is important to consult with the
commands hazardous material control authority.
Containers of unused, contaminated, toxic, corrosive,
and so forth, material have different guidelines for
disposal. Absorbents used in cleaning, applying, or
packing HAZMATS should be treated using the same
precautions followed for the hazardous material they
absorbed. The many procedures and directives that
govern the disposal of hazardous material are
constantly changing and being updated. As mentioned
earlier, supervisors are charged with following
established safety procedures. OPNAVINST 5100.19
(Series), gives further details on disposal of hazardous
When working with solvents, which of the
following actions should you take?
Make sure the space in which you are
working does not have adequate
Remove protective clothing if it gets too
Leave spilled solvents on the deck
Check the labels on all containers of liquid
Most cleaning compounds do NOT contain
Absorbents used in cleaning, applying, or
packing hazardous materials will be treated
and disposed of using the same precautions
followed for the material they absorbed.
