TOOL CHEST
The tool chest (not shown), provides storage space for the electronic repair hand tools, dental tools,
abrasive wheels, solder and solder wicks, eyelets, abrasive disks, ball mills, various burrs, and other
consumables used with the repair procedures. The chest is portable, lockable, and has variously sized
drawers for convenience.
REPLACEMENT PARTS
Replacement parts are provided with the 2M repair set to ensure the technician has the capability to
maintain the equipment properly. Actual preventive and corrective maintenance procedures, as well as
data on additional spare parts and ordering information, are found in the technical manual for the 2M
repair set equipment.
REPAIR STATION FACILITIES
To be effective, 2M electronic component repair must be performed under proper environmental
conditions. Repair facility requirements, whether afloat or ashore, include adequate lighting, ventilation,
noise considerations, work surface area, ESD (electrostatic discharge) protection, and adequate power
availability. The recommended environmental conditions are discussed below. With the exception of
requirements imposed by the Naval Environmental Health Center and other authorities for ship and shore
work conditions, each activity tailors the requirements to meet local needs.
LIGHTING
The recommended lighting for a work surface is 100 footcandles from a direct lighting source. Light-
colored overheads and bulkheads and off-white or pastel workbench tops are used to complement the
lighting provided.
VENTILATION
Fumes from burning flux, coating materials, grinding dust, and cleaning solvents require adequate
ventilation. The use of toxic, flammable substances, solvents, and coating compounds requires a duct
system that vents gasses and vapors. This type of system must be used to prevent contamination often
