General

Safeguards

Safeguards must be provided at three basic locations:

  1. At the point of operation
  2. At mechanical power transmission apparatus
  3. At other moving parts which could potentially create a hazard

Machinery containing moving parts with rotating, transverse, or reciprocating action will be effectively guarded according to OSHA regulations. One or more methods of machine safeguarding must be provided to protect from hazards such as those created by point of operation, nip points, rotating parts, flying chips, sparks and so on. Safeguards must conform to OSHA standards and are recommended to be designed in conformance with the American National Standards Institute (ANSI) B11 standard series (see Resources).

Neither OSHA nor ANSI standards offer guarding requirements for every possible machine configuration; therefore each machine must be evaluated by a knowledgeable, trained person and compared to the appropriate machine safeguarding standard. (See Tools, for general recommendations on ensuring the safety of the operator and other employees.)

Note OSHA does not grant a grandfather clause for old equipment. All equipment must be safeguarded. Equipment must also be installed in conformance to applicable facility standards, such as electrical and seismic.

Authorization

No person will operate machine tools without proper authorization from their supervisor and the machine custodian.
