2.2.3.3 General radiation safety precautions
The Honeywell system has been designed with built-in safety interlocks to handle
anticipated hazards. However, there are a few additional common-sense rules of safety
that must be followed. All personnel working in the area around the head must become
familiar with the following basic precautions regarding these types of devices:
Warning
Laser light or high intensity LED flash
may be emitted from the sensors, which
may cause eye damage. Note that not all
laser lighting is in the visible spectrum.
Laser interlock circuit armed. Sensor
disabled. Sensor software will not be
permitted to enable laser power. No eye
safety hazard. Risk of another person
accidentally re-enabling sensor.
Laser interlock circuit disarmed. Sensor
software will not be permitted to enable
laser power. No eye safety hazard.
• Even though the external radiation field is minimal, personnel should not linger
near the senor heads. Only authorized and qualified personnel with direct business
near the heads are permitted in this area.
•
Do not open or dismantle the sensor heads. Only authorized and qualified
individuals are permitted access to the internal head assembly. Do not insert
hands, fingers, or other body parts in front of the beam exit window. Avoid any direct
body exposure between the sensor heads.
• Do not look directly into the space between the heads if the shutter is open.
• Before approaching the sensor head, determine the status of the source shutter by
observing the shutter status lights. The red light is on when the shutter is open and
radiation is being emitted. The green light is on when the shutter is closed and no
radiation is being emitted.
•
If the head becomes damaged or misaligned, turn main scanner power off to
ensure the source shutter is closed. Authorized personnel must examine the
equipment before returning it to service.
• A site survey must be performed whenever damage to the scanner is suspected.

SCANNER SAFETY AND LOCAL CONTROLS
Safety Precautions
Do not look into gap or insert mirrors for
inspection. Work on heads requires the
laser interlock switch to be turned off and
key removed.
System generally safe, sensor will not
operate when not enabled. Not the highest
level of safety due to risk of accidental
reenabling of sensor at user panel by
coworker: use interlock key.
Normal maintenance work may be done on
the scanner, head, and sensors in this area.
Worker with key ensures higher degree of
interlock control.
