(b) Equipment. In selecting equipment, refer to TM 43-0001-47 and TB 43-0195. The most
appropriate equipment available will be selected and used in the operation. Improvised tools
planned for use in this process should be approved by the appropriate commodity command.
(c) Materials. A careful study will be made of the requirements for materials to go into the
product. Materials include such items as new components, sealing compound, paint, etc.
(6) The original flow sheet acts as a blueprint for the layout of the line. It is useful as a reference and
as a guide for locating the various operating tables or operating rooms. Using the flow sheet, a
clear picture of the job as a whole can be obtained. Changes probably will be made in methods,
tools, personnel, and sequence of operations after work has begun. All the changes will be
incorporated into the final flow sheet, and copies sent later to the next higher headquarters.
f. Standing Operating Procedures (SOP).
(1) An SOP is a step-by-step guide to be used for each maintenance operation. Figure 6, page 14
shows the SOP for one operation; there must be one prepared for each operation. Before writing
an SOP the following questions should be answered:
(a) What is to be done? Refer to DA Form 2407 or DA Form 2415.
(b) Where can it be done? Check with personnel in the surveillance section.
(c) How shall it be done? Refer to the process flow sheet.
(d) With what shall it be done? Refer to the process flow sheet.
(e) What safety precautions are necessary? Refer to the technical manuals for items being
maintained, and to TM 9-1300-206.
(2) SOPs must be clear, conclusive, and easily understood by the operators. They must tell exactly
what the operation is to do, leaving nothing open to interpretation. The SOP for each operation
should tie into the operations before and after, and should detail the identification characteristics
of the operation (see items A through I in Figure 6). Each operation should also describe its
activity, special requirements, equipment, etc. Finally, the SOP should have a cover sheet with
information on it as shown in Figure 7, page 15. As a minimum, an SOP for an operation should
contain the following:
(a) Safety requirements.
(b) Personnel. The fewest required to do the job efficiently and safely.
(c) Explosive limits. Explosive limits are in the DMWR and are expressed in rounds. They are
based on the net explosive weight (NEW) for the ammunition. The limits in the DMWR,
however, are based on depot work flows and are usually too high for ASP operations. The
senior ammunition NCO must consider safety, the size of the operation, and past experience
to decide the explosive limits for a particular operation.
(d) Equipment required for the operation.
