residuals behind that must eventually be deposited in
a controlled sanitary landfill facility.
At all levels of society, we must take appropriate
action to abate pollution and to preserve the
environment by properly disposing of solid waste
Since all Navy facilities must conform to the laws
and regulations of federal, state, and local
environmental agencies, the Navy has produced its
own instruction and guidelines. The information
developed specifically for Navy use is as follows: 29
CFR 1910 (OSHA), 40 CFR 240-262 (series),
OPNAVINST 5090.1 (series), Environmental and
Natural Resources Protection Manual; NAVFAC
MO-213, Solid Waste Management; and NAVFAC
DM 5.10, Solid Waste Disposal.
HAZARDOUS MATERIAL CONTROL
The Hazardous Material Control Program is a
Navy-wide program that enforces the correct storage,
handling, usage, and disposition of hazardous
material. Hazardous waste disposal is a serious
concern to the NCF today. Cleaners, acids, mastics,
sealers, and even paints are just a few of the hazardous
materials that may be present in your shop or on your
project site. As a crew leader, you are responsible for
the safety and protection of your crew.
PROPERTIES OF HAZARDOUS WASTE
Few discarded materials are so compatible with
the environment or so inert as to have no short- or
long-term impact. Hazards that appear minor may
have unexpected impacts long after disposal. When
two or more hazards pertain to a material, the lesser
may not receive the necessary consideration. When
two discarded substances are mixed, a chemical
reaction with severe and unexpected consequences
Since waste is generally a mixture of many
components, its physical and chemical properties
cannot be defined with any degree of accuracy.
Whenever possible, the approximate composition of a
hazardous waste should be ascertained from the
originating source or from the manifest accompanying
the waste being transported. Generally, when one
component predominates, the physical and chemical
properties of the waste mixture are nearly those of the
major component. This is not true for the hazardous
properties of waste mixtures consisting of relatively
harmless major components and small amounts of
highly toxic, radioactive, or etiologically
(disease-producing) active components. The hazard,
in this case, is determined by the smaller component.
The EPA defines hazardous solid waste as any
material that has the potential to produce the following
Cause, or significantly contribute to, an increase
in mortality or any serious, reversible, or
incapacitating reversible illness.
Pose a substantial hazard to human health or the
environment when the hazardous material is
improperly stored, treated, transported, or
By EPA standards, the determining factor for a
material to be classified as hazardous waste is that it
must meet one or more of the conditions of being
ignitable, corrosive, reactive, or toxic, as covered in
the following information.
It is a liquid, other than an aqueous solution,
containing less than 24 percent alcohol by volume and
has a closed-cup flash point of less than 60°C (140°F).
It is not a liquid, but is capable under standard
temperature and pressure of causing fire through
friction, absorption of moisture, or spontaneous
chemical changes, and when ignited, burns so
vigorously and persistently that it creates a hazard.
It is an ignitable, flammable compressed gas,
which is defined as a gas that forms a flammable
mixture when mixed with air at a concentration less
than 13 percent (by volume) or has a flammability
range with air that is greater than 12 percent,
regardless of its lower flammable limit.
It is an oxidizer, such as a chlorate, permanganate,
inorganic peroxide, nitrocarbo nitrate, or a nitrate that
yields oxygen readily, and stimulates the combustion
of organic matter.
It is a watery solution with a pH less than or equal
to 2 or greater than or equal to 12.5.
It is a liquid, that corrodes steel at a rate greater
than 6.35 mm (0.25 inch) per year at a test temperature
of 55°C (130°F).
It is normally unstable and readily undergoes
violent change without detonating.
