BD15-95-555-002 FIXED GAS FIRE PROTECTION SPECIFICATION (CRANE).pdf

This document is a technical specification drawing for a Fixed Gas Fire Protection System (CRAD) used by the U.S. Army Aviation and Missile Command. The drawing, designated BD15-95-555-002, provides detailed engineering specifications for an automated carbon dioxide gas fire suppression system designed for machinery compartments in military vehicles or equipment.

The system includes several key components: carbon dioxide gas containers with a fire control monitoring panel, CO2 piping distribution network, a diesel engine generator set, heat exchanger, hydraulic reservoir, and associated control instrumentation. The specification requires diesel engine-powered equipment to be housed in the machinery compartment with automatic carbon dioxide suppression capability. Technical requirements include alarms and controllers that automatically activate the fire suppression system upon detection of hazardous conditions, quality-controlled double gas spent cylinders, pressure-operated switches, optical detectors, pressure-operated alarm and pneumatic dump features, and remote pull-line activation with necessary hardware. All piping, tubes, and fittings must be 316 stainless steel with brazing. The system must comply with MIL Rules for Building and Checking Steel Vessels (1968), Part 4, Section 5. Detailed installation drawings, bill of materials, and component specifications are provided across multiple pages with isometric details, manifold configurations, and cylinder bracketing arrangements. The document includes revisions tracking and references to Herbert Fuller as the design organization.
