2.5 Lock-out/Tag-out

The Lockout and Tag out Procedure protects employees from injury or death from stored energy in, on, from, or around
machines/equipment during repair, maintenance, operation, and associated activities.
The Energy Lockout and Tag out Policy requires all personnel to follow the procedure in this document. Personnel refers to 3D
Systems employees, temporary employees, general contractors, or subcontractors.

2.5.1 Policy

In the operation and maintenance of the DMP system, it is necessary to inspect, repair, clean, adjust or work on equipment,
facilities, and instruments of all types. 3D Systems' policy is that this work will be done with maximum safety to all personnel
and equipment involved. Individuals must assume responsibility for their own safety as well as that of fellow employees. This
Lockout and Tag Procedure is essential to fulfill that responsibility and must be followed in all areas.
2.5.2 Principles, Beliefs and Philosophy
Principles: The following principles provide the basis for lockout and tag:
• Lockout is defined as the determination by area management, operating personnel, or service personnel that the
equipment or process needs to be isolated for repair, adjustment, or replacement so that inadvertent operation of the
equipment or process does not cause injury.
• Servicing equipment in a powered-on condition presents unique hazards and must be performed only by personnel
trained to perform the needed functions. When dealing with potentially hazardous situations, approved area procedures
must define how to troubleshoot or operate equipment or processes in a safe manner. If there are no area-approved
troubleshooting or operating procedures, then the equipment or process must be locked out.
Beliefs: 3D Systems believes the following:
• All equipment and processes can be worked on safely by eliminating the hazards or by taking precautions to protect people.
Philosophy: Our philosophy is to secure energized or power-driven equipment prior to adjusting, repairing, or replacing in a
way that protects employees and customers from injury and equipment from damage.

2.5.3 Rules

• All equipment shall be locked out to protect against accidental or inadvertent operation when such operation could
cause injury to personnel. Do not attempt to operate any switch, valve, or other energy isolating device bearing a lock.
• The electrical disconnect panels of all equipment bays not in use must be locked out/tagged out by the area manager.
2.5.4 Electrical Lockout-tagout Procedure
1. Switch off the machine following the regular shutdown
procedure.
