CAUTION
Danger of cutting on the IC and FC camera
There is a risk of cutting your fingers along the edges of the mirror.
► Wear laboratory gloves as protection and avoid touching the edges.
► The laboratory gloves are also required for effective cleaning (fingerprints!).
CAUTION
Only one person must be present at each component preparation station at any
given time.
This is to ensure the safety of the operator and the safety of the second person. Pulling in
the component trolley is a two-handed operation, so only one person can be reliably protec-
ted from the possible risks.
1.1.8 Safety Instructions on Hazardous Materials
CAUTION
Observe the safety data sheets
Observe the applicable safety data sheet, when handling hazardous materials (e. g. Loctite
241, ethanol).
1.2 Preparatory Work...
Purpose and scope
Before performing any preventive maintenance work, conversion work or service work, a procedure
of locking and tagging must be followed and warning signs must be attached if not stated other-
wise. If it is not necessary to switch off the machine, it is explicitly mentioned.
The procedure, when followed correctly, eliminates the possibility of an employee being injured.
NOTICE
Additional safety measures
This procedure represents the minimum lock out and tag out requirements for the machine
during preventive maintenance work and service work. Any additional safeguards needed
to complete work safely can be specified by facilities supervision, the safety officer, the
safety committee and the health department.

► Turn the operating lever(1) counter-
clockwise.
► Use the screwdriver to push the lock-
ing lug(2) out of the operating
lever(1).
► Secure the operating lever with a pad-
lock (3).
► Alternative: Attaching warning signs:
If a machine can be locked, it must be.
However, there are situations where energy isolating devices cannot accommodate locks. In
these cases, the energy isolating devices must be tagged to warn employees that the
machine is de-energized for servicing. The tag or label must be securely fastened, it must be
placed in a position visible to all and it may only be removed by the person who attached it.
