3 Warnings
There are hazardous aspects associated with the operation of this equipment. Under normal
use, no hazard is presented to the operator. The areas where a potential hazard may occur
are listed in the following sections.
3.1 General
The following warnings are identified as hazards:
• Always observe all current safe working practices when working on electrical
systems.
• Both X-ray production and manipulator use are interlocked to the door closed switch.
• Ensure the required space set out in the installation drawing is left around the system.
• The system is designed to be used either standing or on a draftsman's chair. Users
should perform their own risk assessment for operator comfort.
The following warnings are identified as mandatory actions which must
be followed to prevent a hazard:
• If the operator door interlock switches become damaged, the operator must stop
using the system at once and report this damage to Nikon Metrology.
• Damage, however small, to the cabinet door glass (where fitted) must not be
repaired, as the glass is a special leaded type. If damaged, the system must not be
used, and the damage reported to Nikon Metrology.
The following warnings are identified as prohibited actions that must
not be performed:
• Do not remove any panels or covers from the machine whilst operating or powered
up in any way.
• Do not try to produce X-rays with any safety interlock overridden or with any radiation
shielding removed.
• Do not apply power to the machine until all covers or panels have been fitted and
secured correctly.
• Never operate the system at full X-ray power without a sample between the X-ray
source and the imaging system.
• Do not interfere with or try to override the door interlock switches as this may result in
exposure to mechanical or radiation hazards.
• Do not block or restrict any exterior vents.
