ANSI Z-365 CHECKLIST
Introduction
The American National Standards Institute (ANSI) has published a
draft document
establishing ergonomic guidelines for the control of upper
extremity CTDs (ANSI Z-365
draft, 1993). Included in the guidelines is the checklist that
appears in the following
pages. Relevant features of the checklist are given below:
The checklist is limited to analysis of ergonomic issues
impacting the upper extremities.
The checklist would be appropriate for the evaluation of office
work environments, and
many "assembly" or "processing" line work environments.
The checklist requires fairly intensive analysis on the part of
the user. To determine
many of the criteria set forth in the checklist, it is
anticipated that videotape analysis of
jobs will be required.
The checklist establishes "trigger scores" based on the body
part and motion. For
example, if the sum of ergonomic issues identified for shoulder
flexion is equal to or
greater than 6, it indicates the presence of an ergonomic
situation warranting
implementation of some control strategy, independent of
injuries/illness in the job being
analyzed.
Instructions: Across each row, score the task you are evaluating
for each of the
relevant items. Add the scores across the row and compare them
to the trigger score
in the right-hand column. If the total is equal to or greater
than the trigger score, there
is a potential ergonomic issues related to that part of the
body.
