WARNING: The Hazard Must Be Accessible Only through the Sensing Field
The installation of the SX5 must prevent any individual from reaching around, under, over or through the
sensing field and into the hazard without being detected. Mechanical barriers (for example, hard (fixed)
guarding) or supplemental safeguarding may be required to comply with this requirement, and is
described by ANSI B11.19 safety requirements or other appropriate standards. Failure to follow these
instructions could result in serious injury or death.
3.2.1 Unmonitored Areas
WARNING:
• Unmonitored areas can create an access route to the hazard or a blind zone where a person
cannot be detected. The area behind the Scanner and near it, on either side is not monitored.
• Failure to minimize the unmonitored area could result in serious bodily injury or death.
• Minimize the unmonitored area so that no one can access this area undetected (for example, by
recessing the Scanner into the machine, using supplemental safeguarding, or using mechanical
barriers to prevent access).
Behind and To the Sides of the Scanner
The area behind and on either side the SX5 is not monitored. It must not be possible to walk in unmonitored areas or
otherwise access them. This can be accomplished by recessing the SX5 into the machine, using supplemental
safeguarding, or using mechanical barriers to prevent access. If there is a possibility that the SX5 could be used as a
climbing aid or standing surface, use a physical cover set at an angle over the SX5.
Special attention to these areas must be addressed in vertical Safety Zone applications so that the resolution at the edges
of the Safety Zone does not increase. If an increased resolution cannot be prevented, then the worst-case resolution must
be used to determine the Dpf (U.S. formula) or the C factor (European formula) in the safety distance calculations.
