(c) Personnel who are experienced in the operation must be assigned to various sections of the
job. Inexperienced personnel must receive training so that they will be able to help when
needed.
(d) Technical information must be obtained so that the job will be performed correctly.
Consideration must be given to safety so that each operation may be conducted with minimal
possibility of injury to either the operator or the equipment.
(e) Once operations are begun, provisions must be made for removing bottlenecks and increasing
production, making operations more simple, and increasing safety.
(f) Operational planning is used to plan jobs of other types by deciding in advance of starting the
operation. Critical questions that must be considered are: What is to be done? How is the
work to be done? Who is to do the work? Where is the work to be done?
(2) These items apply themselves very well to maintenance. The paperwork applied, to be discussed
later, is merely a step in answering these questions so as to build up to an official line layout.
d. Renovation Facilities.
(1) The maintenance building is a specially designed structure which provides the maximum degree
of safety for operators, while at the same time facilitating production. See Figure 4, page 10.
(2) The building is constructed with laced reinforced concrete dividing walls to prevent simultaneous
detonation of the explosives in the building. They are not designed to provide complete
protection for personnel. The dividing walls are a minimum of 12 inches thick (some buildings
are constructed with twice this thickness so that completely separate operations can be conducted
on both sides of the building).
(3) The building walls and roof coverings should be of non-combustible material. The interior
surfaces should be of fire retardant material and as free from cracks as possible. Seams should be
taped over, and if painted, the paint should be a gloss to facilitate cleaning. The building is
designed to vent an explosion.
(4) The building is designed so that materials enter one end of the building and flow to the other.
Conveyors and hoists are setup throughout the building along with larger items of machinery,
electrical power, and compressed air.
(5) The work is divided so that different operations are performed in each of the cubes. The building
can be adapted for numerous jobs by installing or removing equipment and machinery.
(6) Marking and color coding of areas and equipment, water lines, high pressure air lines, hazard
areas, electrical lines, etc., contribute to safety. For example, color coding for identification of
the different power lines, high pressure lines, and hazard areas could be as follows:
(a) High pressure water lines ----- Red.
(b) High pressure air lines -------- Green.
