6.7.3 Performing a Lockout/Tagout
The Lockout/Tagout (LOTO) procedure defines the process by which the microscope is isolated
from potential hazards associated with the unexpected release of hazardous energy. This proce-
dure needs to be performed when service, maintenance work, or unscheduled repairs can cause
exposure to any form of hazardous energy.
Info
The customer is responsible for providing instructions on how to operate the energy-isolating
devices properly.
Prerequisite ü
The microscope has been de-energized.
1. Verify that the microscope has been de-energized properly.
2. To secure the microscope against accidental re-activation, lock the energy-isolating devices.
