task at an advanced base. It is a carefully balanced
combination of material, equipment, and/or
personnel.
Each functional component is grouped
according to its primary function into 1 of 11
major groups, including aviation. Each major
group is identified by letter designation and title.
The functional components contained in each are
identified by a combination letter, number, and
its title designation. The major group designation
for aviation is “H.”
“H” components are designed to provide
maintenance, support, and operation of aircraft
in an advanced area under combat conditions.
“H” components may be combined with other
functional components to form several types of
air stations.
Complete information and data are given in
the abridged and the detailed outfitting lists for
functional components. It should be apparent to
the AMEC that the advanced base requirements
may not be exactly as they appear in the Advanced
Base Initial Outfitting Lists. To use these lists as
guides, it will be necessary, in most cases, to alter
or tailor them to fit the individual needs of the
unit about to deploy.
Other necessary repair parts, supplies, and
equipment may be determined from the outfitting
lists for the aircraft or other weapon systems to
be supported.
It is quite likely that the AMEC will be
required to advise the personnel office in making
assignments of individuals to advance base or
forward area operating units. It would seem
logical that the number of AMEs assigned to
deploy be in the same ratio as the percentage of
supported aircraft scheduled to deploy. This may
be true if the proposed flight hours per aircraft
of the detachment exactly equalled the planned
utilization of the remaining aircraft. There must
also be no significant environmental problems to
be overcome (i.e., excessive heat or excessive cold
conditions, depending on the location of
deployment). The list of personnel assigned to
deploy should represent a cross section of the skill
levels available unless special maintenance factors
indicate otherwise. The selection of personnel
should be made as objectively as possible so the
deployed unit can function as safely and
efficiently as possible.
SAFETY PRECAUTIONS FOR
HAZARDOUS SUBSTANCES
Learning Objective: Identify safety
precautions for working with hazardous
substances and equipment.
There are many ways for a careless or
inexperienced worker to hurt themselves or others
on the job. This section discusses safety
precautions in three hazardous work areas: liquid
oxygen, gaseous oxygen, and high pressure air.
Other specific safety precautions are discussed in
OPNAVINST 5100.19 (series).
It has been said that every safety precaution
has been originally written in blood. There is no
room for complacency in the performance of
AME tasks. Every job must be performed in a
“heads-up” manner to ensure maximum safety
awareness is maintained. Anything less can and
will be disastrous.
LIQUID OXYGEN
Aviators breathing oxygen (ABO) comes in
both gaseous (type 1) and liquid (type 11) states.
Liquid oxygen (LOX) is converted to a gas before
its delivered to the aircrew. LOX requires frequent
monitoring to prevent contamination and to
ensure safe use. A surveillance program is the
primary method of ensuring that each operation
in the LOX supply system is carried out in strict
compliance with established procedures. Surveil-
lance begins with procurement or generation of
LOX and continues throughout storage, handling,
transfer, and servicing of aircraft.
The best assurance of personnel safety lies in
the safety education of the people themselves. The
safety of personnel can be assured only when there
is thorough understanding of potential hazards,
the correct procedures and equipment are used,
and the equipment is in good working condition.
Knowledge of a job situation and appropriate
safety equipment is vital to successful completion
of a job. Follow established safety procedures in
NAVAIR 06-30-501.
Description and Properties of
Liquid Oxygen
Oxygen can exist as a solid or gas, depending
upon the temperature and pressure under which
it is stored. At atmospheric pressure, oxygen exists
as a solid at temperatures below its melting point,
– 361°F (–281°C). Solid oxygen turns into a
