1 Purpose
The purpose of these requirements is to ensure the safe use of machine tools. They cover the procurement, safeguarding, use, and maintenance of such tools. They apply to workers, supervisors, machine and shop custodians, and building and area managers.
2 Requirements
Use of machine tools must meet the following general requirements.
2.1 Procurement
All machine tools will meet the applicable standards of this program (see Chapter 25, “Machine and Portable Tools”, Section 6.1, “External Requirements”).
2.2 Authorization
Only authorized workers will be permitted to operate machine tools. Machine tool use is authorized through a machine-specific competency evaluation, as described in Chapter 25, “Machine and Portable Tools”, Section 4, “Training”, for each machine to be operated. Hand tool and portable power tool use is authorized through an activity and training authorization (ATA) or job safety analysis (JSA) (see Chapter 2, “Work Planning and Control”).
2.2.1
Working Alone
When a machine tool is in use, a second person in addition to the operator must be present. (For this purpose, “present” means that they would know if the machine operator needs emergency assistance. This should be clarified in the shop-specific safety rules or machine-specific competency standard.) That second person must, at a minimum, be able to shut the machine off and contact emergency services. Exceptions to this working-alone policy may be made for tools that, while in setup or operation, do not pose a risk of significant injury to a person working alone. These cases must be documented in the shopspecific safety rules or the machine-specific competency
