2.4 Order of precedence. Unless otherwise noted herein or in the contract, in the event of a conflict between
the text of this document and the references cited herein, the text of this document takes precedence. Nothing in this
document, however, supersedes applicable laws and regulations unless a specific exemption has been obtained.
3. REQUIREMENTS
3.1 Acquisition requirements. Equipment shall be designed and constructed to comply with the requirements
3.2 Design requirements.
3.2.1 Safety. Equipment shall be designed and constructed in a way that will ensure safety to operating and
maintenance personnel. When the equipment is properly installed and the enclosure is grounded, there shall be no
accessible way for operating personnel to receive an electric shock even though an internal fault may exist between
any two circuits, between any circuit and a structural member, or between any circuit and ground. The design shall
hold to a practical minimum the possibility of maintenance personnel being exposed to electric shock while
servicing, adjusting, or checking out the equipment. For access to such circuits, further positive action shall be
required to remove a cover or open a portion of the guard means. A warning plate shall be prominently displayed to
remind the maintenance personnel of appropriate precautions to ensure de-energization of the guarded circuit
(see 3.17).
External moving parts which are a potential hazard to personnel shall be avoided. When their use is
unavoidable, positive protection in the form of a guard shall be provided. Sharp corners and projections which may
cause injury or catch on clothing shall be avoided.
3.2.2 Compatibility. Materials and parts used in equipment shall be mutually compatible with the environment
for which they are intended.
3.2.3 Accessibility. All parts, assemblies, and other items which may require servicing or replacement during
the life of the equipment shall be readily accessible for such actions without major disassembly of the equipment
and without removing the equipment from its foundation. Installation information shall be in accordance with
MIL-D-23140 (see 6.2). Access to internal parts of equipment, other than rotating machinery, shall be from the
front of the enclosure since units are likely to be installed with their backs to bulkheads and their sides adjacent to
other equipment. Operating controls and indicators shall be conveniently located on the front of the enclosure or on
an operating panel appropriately oriented with respect to the operator's station. Non-operating controls shall be
located behind access doors within the enclosure or in other accessible locations within the equipment. Adjustment
mechanisms; such as for calibration, compensation, or alignment, shall be located within the equipment and shall be
readily accessible when the equipment is open for servicing (see 3.2.1 for protection to personnel).
