Employees shall:

• Select the correct tool for the task and material.
• Inspect tools before use and remove defective tools from service.
• Use tools only for their intended purpose.
• Follow manufacturer instructions and applicable site requirements.
• Use required guards, handles, accessories, and protective devices.
• Wear PPE appropriate to the tool and task.
• Stop work and report unsafe conditions or damaged tools.

Required PPE

PPE shall be selected based on the hazards created by the specific tool and task and may include:

• Safety glasses with side protection; a face shield may be required for flying-particle or splash hazards.
