ANSI Z359.3, “Safety Requirements for
Positioning and Travel Restraint Systems”

Work Positioning Defined:

“Supporting a worker on a vertical surface while working
with hands free”


Work positioning systems are designed to prevent a fall
from occurring. When a fall hazard is present, positioning
systems must be used in conjunction with a separate and
independent personal fall arrest system
Travel Restraint Defined:

“Limiting a worker’s travel in such a manner that they
cannot reach a fall hazard zone”


Restraint systems do not support a portion of the worker’s
weight
Used only on walking/working surfaces with a slope
between zero and 18.4 degrees
