ACCIDENT SCENARIO
Consequence:
1.1 Hitting
1.12 Perforation or puncture
Situation:
Standing near the loading/unloading area.
NOTE: risk assessed after machine setup for changing from TANDEM processing
to SINGLE-STEP, loading/unloading working cycle.
Event:
Risk of getting hit by tool fragments or by the tool itself, projected outward as a
result of a breakup.
Body part:

RESIDUAL RISK
After machine setup for changing from TANDEM processing to SINGLE-STEP, loading/unloading
working cycle, a risk remains of getting hit by tool fragments or the tool itself, projected outward as a
result of a breakup, if in the course of the setup procedure the central guard for the two axes (Y1-Y2) is
not reassembled (PROTECTION MEASURE M11).
REDUCTION MEASURES
Mechanical:
The perimeter protections (PROTECTION MEASURE M04), the access doors
(PROTECTION MEASURE M05), the central protection installed between the piece
support devices (axes Y1 and Y2, PROTECTION MEASURE M11), and the
combinations of movable guards (PROTECTION MEASURE M06) have been
properly designed to withstand any tool breakage and allow containment.
Electrical:
-
Informative:
At the end of the TANDEM processing cycle, the maintenance technician who carry
out machine setup is required to reassemble the central guard (PROTECTION
MEASURE M11) before enabling the SINGLE-STEP, loading/unloading working
cycle. Follow the procedure described in the instruction manual.
NOTE: The ejection of tool fragments is reduced to a minimum, at least along the
direction of two horizontal axes (ref. EN 848-3:2007+A2:2009-, section
5.3.7.1.2.3.1).
