Risk Assessment
Adept Quattro s650H Robot User’s Guide, Rev A 27
2.4 Risk Assessment
Without special safeguards in its control system, the Adept Quattro s650H robot could
inflict serious injury on an operator working within its work envelope. Safety standards in
some countries require appropriate safety equipment to be installed as part of the system.
Table 2-2 lists some of the safety standards that affect industrial robots. It is not a complete
list. Safeguards must comply with all applicable local and national standards for the
location where the robot is installed.
Exposure
When Arm Power is ON, all personnel must be kept out of the robot work envelope by
interlocked perimeter barriers. The only permitted exception is for teaching the robot in
Manual Mode by a skilled person (see “Qualification of Personnel” on page 32), who must
wear safety equipment (see “Safety Equipment for Operators” on page 33) and carry the
Adept pendant. Therefore, exposure of personnel to hazards related to the robot is limited
(seldom and/or short exposure time).
Severity of Injury
Provided that skilled personnel who enter the robot work envelope are wearing
protective headgear, eyeglasses, and safety shoes, it is likely that any injuries caused by
the robot would be slight (normally reversible).
Avoidance
A programmer must always carry the pendant when inside the work envelope, as the
pendant provides both E-Stop and Enabling switch functions.
For normal operation (AUTO mode), user-supplied interlocked guarding must be installed
to prevent any person entering the workcell while arm power is ON.
