The food service division is responsible for routine
preventive maintenance of all mess deck equipment.
Any major troubleshooting, repairs, or overhauls are the
responsibility of the repair or auxiliary division. You
should advise the division responsible to submit all
requests for repairs and parts replacements on Ship’s
Maintenance Action Form, OPNAV 4790/2K.
GALLEY EQUIPMENT
Galley equipment must be maintained in a safe,
sanitary, and economical way. Enginemen maintain this
equipment, and they frequently tram the food service
personnel on how to properly operate the equipment. It
is always a good practice to post operating instructions
near the equipment. This will help to ensure that the
operators do not abuse the machines. You may be called
on to help inspect galley equipment. You can also help
determine the type of maintenance and the extent of
repairs required to keep the equipment safe and efficient.
Remember, the medical department is responsible for
conducting sanitary inspections.
The supply
department is responsible for keeping food-handling
equipment clean. And, the engineering department is
responsible for maintaining the operation of this
equipment.
REFRIGERATORS (SELF-CONTAINED)
Galley refrigerators will not have any problems if
the user will do the following:
- Allow proper clearance in the back of the
refrigerator. The refrigerator must have a
distance of at least 4 inches away from the
bulkhead. Any obstruction will reduce the
airflow required for an air-cooled condenser.
Do not overload the refrigerator.
Properly store foods with space for air
circulation.
Follow the MRC for routine maintenance like
defrosting and cleaning.
Do not use any sharp objects like knives or
scrapers when defrosting the refrigerator. This is
not an acceptable procedure for removing frost
buildup on a refrigerator.
When repairing or overhauling a refrigerator, refer
to the manufacturer’s manual. “Refrigeration System,”
Chapter 516 of NSTM contains general procedures on
how to maintain or repair a self-contained refrigerator.
Follow all the necessary safety precautions when
handling and disposing of a refrigerant!
