4-1. General Shop Rules. The maintenance
instructions and procedures contained in this chapter are
general in nature and apply to instruments installed in
Department of the Army aircraft. Specific maintenance
instructions that are peculiar to particular instruments
manuals and instrument overhaul manuals and will be
used, when specified, in conjunction with instructions
contained in this chapter. The practices and procedures
described in this chapter pertain to the manufacturing
and repair functions of aviation activities and are
applicable to all levels of maintenance. Because of the
many types of Army aircraft, each shop within the
manufacturing and repair section must, of necessity,
have personnel trained in general practices and
procedures to the extent that different type and model
aircraft do not upset a smooth running shop.
a. Responsibility. All supervisory personnel are
responsible for a continuing and effective shop safety
program. To implement and maintain this program,
shop supervisors will utilize bulletin boards, signs, and
any other effective method. Shop personnel will
cooperate in the shop safety program by making helpful
recommendations, and continually exercising care and
caution in the operation of all shop equipment. All shop
personnel will strive to improve the safety program and
be especially alert to observe and correct hazardous
conditions and unsafe shop practices. All accidents, no
matter how minor, shall be reported to the shop
supervisor, and all published instructions regarding
safety shall be strictly adhered to. Also, safety
engineers and safety officers will ensure that proper
safety procedures are adhered to in accordance with AR
385-10, Army Safety Program; AR-385-30, Safety-Color
Code Markings and Signs; The Occupational Safety and
Health Act of 1971, OSHA 1910.251; all applicable fire
codes, NFPA 410; and other accepted civilian and
military safety practices.
b. Shop Housekeeping. Housekeeping is the
yardstick by which the shops are judged. A clean, well-
arranged shop is a safe shop and reflects credit on all
personnel concerned with its operation. The following
shop practices shall be observed:
(1) Oil pans or drip pans shall be used
where leaking oil, grease, and similar materials may
cause hazardous accumulations on equipment or floors.

shall be adequately illuminated.
c. Equipment Safety. Unsafe equipment shall be
reported immediately. The following equipment safety
practices shall be observed:

operators with sufficient space to handle materials and
perform job operations without interference.
(2) Bolt down all machinery that can move
or walk due to vibration (drill press, bench grinder, etc.).

shall be used to ground all stationary and portable
machines, equipment, or other devices in which static
charges may be generated, or which require electrical
circuits of a hazardous nature.
