Most eye injuries which occur on the job do so because the person was
not
wearing eye protection or was not wearing the proper eye protection.
Lack of eye protection and inadequate eye protection are the two leading
causes that contribute to eye injury at work. Most of the eye injuries
occur
among craft workers and industrial equipment operators. Dusts, flying
particles, rays and fumes are among the most common culprits.
The American National Standards Institute (ANSI) sets the standards for
safety glasses. The ANSI requires that safety glasses be able to
withstand
the impact of a quarter inch steel ball traveling 150 feet per second.
Frames of safety glasses must also meet strict standards for strength
and
heat resistance. The ANSI Z87 standards are the safety standards by
which
all safety glasses must conform to for impact resistant lenses and
frames.
According to ANSI standards, lenses must be able to pass a "drop ball"
test.
The test involves dropping a hard ball onto the lens from a certain
height.
If the lens cracks or shatters, it fails the test. The reason for the
failure may be because the lens is too thin or the material is
defective.
It is so important to wear safety glasses when operating machinery.
Regular
glasses do not withstand the impact of projectiles such as flying pieces
of
metal, which can shatter regular glasses. When working with machinery
such
as cutting tools, safety glasses protect from the hot bits of metal.
Safety
glasses with foam or rubber around the lens provide better protection
from
dust and flying particles than safety glasses with only side shields.
