Sawyer offers additional features to support further risk reduction if necessary, e.g. operation at
reduced speed, Category 0 E-stop and protective stop functions, however, the integrator is respon-
sible for ensuring that:
•
All hazards have been eliminated or minimized in the final installation using
appropriate means,
•
Risks have been reduced to levels as low as reasonably practicable, and
•
Residual risks have been communicated to end users.
The sections below offer guidance on best practices for a number of topics relating to risk assess-
ment and use of Sawyer.
Use considerations
Collaborative use of Sawyer presumes that there is no safeguarding or presence sensing used, and
as such, expected or unexpected contact between personnel and Sawyer or its end-effectors/parts
will not pose unacceptable risks. Expected or unexpected contact with other objects in the work-
space (equipment, surfaces, conveyors, etc.) will likewise not pose unacceptable risks. If the inte-
grator’s risk assessment determines hazards are present in their specific application that pose
unacceptable risks to users, then the integrator must use appropriate risk reduction measures to
eliminate or minimize those hazards until risks are reduced to an acceptable level. Any use of Saw-
yer prior to appropriate risk reduction (if required) is considered unsafe.
Safe use of Sawyer requires that integrators and users follow Rethink’s installation and mounting
instructions for Sawyer.
Sawyer is not intended for use in explosive atmospheres or any environment designated as a haz-
ardous location under relevant electrical codes.
Use of Sawyer without perimeter safeguarding requires risk assessment to determine whether or
not associated hazards pose unacceptable risks, for example, hazards could be present with the
use of sharp end-effectors/parts or with the handling of toxic or other hazardous substances. The
integrator must take into account such hazards and their associated risk levels through risk assess-
ment and identify and implement appropriate measures to reduce risks to acceptable levels.
