SECTION 9—METHODS OF SAFEGUARDING
AUXILIARY SAFEGUARDING ON POWER PRESSES
Auxiliary safeguarding can provide additional protection from injuries for all personnel in the machine area. It is most often used in conjunction with
primary safeguarding devices. Auxiliary safeguarding also involves the safeguarding of other hazardous components or openings on machines.
Danger signs, used for warning, must be mounted on the machine in a position that is readily visible to the operator, setup person or other
personnel. Hand tools can be used as auxiliary safeguarding. They are often used when feeding and retrieving small pieceparts. Hand tools by
themselves are NOT a point-of-operation safeguarding device.
OSHA 1910.217 (c) (Ref. MPPS, page 13)

Hand feeding tools.
Hand feeding tools are intended or placing and removing
material in and from the press. Hand feeding tools are not a point-of-operation guard
for protection device and shall not be used in lieu of the guards or devices required.
OTHER SAFETY CONSIDERATIONS
Other areas of machine safety must be considered in order to comply to the OSHA
regulations and ANSI standards, as we know them. This includes, but is not limited to, items
such as a main power disconnect switch, which must be provided for each machine, and
a magnetic type motor starter for the main drive motor. All mechanical power-transmission apparatus of the machine, such as rotating flywheels,
gears, sprockets, chains, and shafts, must be covered in accordance with OSHA 29 CFR 1910.219. As with all machinery, best safety practices
must be a continuing program. The operator, die setter and all personnel must be fully trained and instructed on all safety procedures and have full
knowledge of the safeguarding device being used.
When using any of the devices described for point-of-operation safeguarding, the sides and rear of the hazardous point-of-operation area must be
safeguarded to protect the operator and other employees in the machine area (OSHA 29 CFR 1910.212).
Note: The preceding point-of-operation safeguarding options are explained in OSHA 29 CFR 1910.217 regulation for mechanical power presses
and ANSI B11.1 standard entitled “Mechanical Power Presses—Safety Requirements for the Construction, Care and Use.” Also see the
enclosed Rockford Systems’ booklet entitled “Mechanical Power Press Safety” (MPPS).
