| The American National Standards
Institute (ANSI) approved the American National Standard for High-Visibility
Safety Apparel (ANSI/ISEA 107-2004). This standard provides
consistent, authoritative guidelines for the selection and use of high-visibility
apparel in the United States.
ANSI/ISEA 107-2004 is a voluntary
standard that offers performance specifications for reflective materials,
including minimum amounts, placement, background material, test methods
and care labeling. In simplest terms, the ANSI/ISEA 107-2004 standard
provides for a high degree of reflective material incorporated into garments...thus
improving visibility...and safety.
ANSI/ISEA 107-2004 specifies
three classes of garments based on work environment:
Class III
Class III garments provide
the highest level of visibility to workers in high-risk environments that
involve high task loads, a wide range of weather conditions and traffic
exceeding 50 mph. Class III garments, provide coverage to the arms
and/or legs as well as the torso, and can include pants, jackets, coveralls
or rain wear. The standard recommends these garments for all roadway construction
personnel and vehicle operators, utility workers, survey crews, emergency
responders, railway workers and accident site investigators.
Class II
Class II garments are for
users who need greater visibility in poor weather conditions and whose
activities occur near roadways where traffic speeds exceed 25 mph. This
class of garment is suitable for railway workers, school crossing guards,
parking and toll gate personnel, airport ground crews and law enforcement
personnel directing traffic. Carolina Safety Sport manufactures a full
range of vests that conform to Class II requirements.
Class I
These garments are intended
for workers who have ample separation from vehicular traffic that does
not exceed 25 mph. Class I garments are often safety vests thay are recommended
for parking service attendants, workers in warehouses with equipment traffic,
shopping cart retrievers, sidewalk maintenance workers and delivery vehicle
drivers.
