A 2010 priority: Use proper head, eye & face PPE

Revisit the standards, challenges and trends in PPE
In spite of one of the worst economic climates
in nearly 60 years and the resulting cost cutting,
the dedication to proper, quality personal
protective equipment (PPE) in the workplace
was never abandoned. In fact, recent studies cite
that in 2009, 73 percent of companies devoted
more resources to risk management activities,
including compliance and safety.
As the industry looks to the year ahead, it is
important to revisit the standards, challenges and
trends in PPE.
Eye protection
As with any safety guidance, recommended
eye, head and face protective equipment for your
worksite is based on the results of an assessment
of potential hazards, as well as comprehensive
knowledge of all applicable standards, laws and
regulations.
Historically, it
was hard to get
employees to comply
with wearing
proper protective
eyewear because it
was, quite frankly,
ugly. Over the
years, manufacturers
figured out
that if they made
protective glasses
more aesthetically
pleasing, sales and,
even more importantly,
use, would
increase. As a
result, modern eyewear
is lightweight,
adjustable and cost effective. In fact, eyewear is so
inexpensive, manufacturers rarely offer free lens
replacement because buying new pairs is more cost
effective.
Recommendations for protective eyewear on the
worksite are governed by OSHA and are required
to meet the American National Standards Institute
(ANSI) standard Z87.1-2003 when manufactured.
The standard largely addresses the eyewear’s ability
to withstand impact; however, lens clarity can
be among the most important
factors in protective eyewear.
Look for manufacturers that
use virgin resin in order to
ensure maximum clarity —
unclear lenses can cause
employees to experience
headaches or slight disorientation
that adds hazards to
the worksite.
Some 75% of all lenses
sold are clear or clear
with an anti-fog treatment.
Consider amber or lightblue
colored lenses to help
reduce glare. Additionally,
indoor/outdoor lenses can
help employees assimilate
when moving between different
work environments in artificial or natural light.
Shaded and mirrored lenses (sunglasses) come in a
large variety of tints and are appropriate in outdoor
situations where both impact and glare protection
are required. In the case of welding eyewear, glass
shades are infrared and vary from lighter 3.0 to
darker 5.0 shades or higher depending on whether
the employee is welding or will be in the vicinity
of welding activity.
One of the fastest growing varieties of protective
called a “reader”—
meaning it
has a magnifying
glass on the bottom
of the lens (similar to a
bifocal lens). The growth
in this segment is due to
the aging demographic of
the workforce and the resulting
eyesight changes that come with
aging. OTG or Over-the-Glass eyewear
is intended to fit over the top of
prescription eyewear.
Head protection
If the work environment requires it, the
standard head protection is a hard hat. They
are produced under standards specified by ANSI
Z89.1-2009. There are essentially two types, based
on the potential impact protection required. Type
I protects against injury from above and Type II
protects against injury from the side. Standards for
head protection also consider the risk of interaction
with electric elements (Class E, G or C), including
those that are completely dielectric or without
metal parts.
The biggest concern in head gear, however, is
maintenance. Over the years, it has become something
of a tradition for employees to attach stickers
or other decals to their hard hats from job sites.
These decorations make the hard hat extremely
difficult to inspect for cracks or other abnormalities
(as required by the regulations) on the outside,
though some visual inspection can happen inside
the hat. While most work sites stop short of prohibiting
decals, a compromise could be found in
imprinted logos now sold on more than 50 percent
of all hard hats nationwide. These make the head
gear easy to customize, but still able to be safely
and comprehensively inspected for defects.
Three non-mandatory tests outlined in the recently
updated ANSI/ISEA Z89.1-2009 exist to identify
head protection that meet minimum requirements
for reverse donning (hard hats can be worn backwards
or with a swing ratchet suspension), lower
temperature (appropriate for -30ºC or -22ºF),
and high-visibility hard hats (those with bright
colors or reflective materials and used primarily by
road construction crews). Smaller, lighter “bump
caps” are also available for industries such as food
service, though there is no requirement to do so.
Face protection
Face shields come in four primary materials:
polycarbonate, propionate, acetate and PETG. Each
has strengths in areas such as heat or scratch resistance,
impact protection or superior optics. In many
cases, these strengths are weighed against cost in
purchasing decisions. Traditionally, PETG is a disposable
product that meets ANSI standard Z87.1
for face protection, but it does not address ANSI
Z87.1+, a newer, tougher standard for high-impact
protection. Polycarbonate is good for impact and
heat resistance and optics but can be susceptible
to
scratching.
Acetate
is resistant to
scratching but
not as effective for
impact protection.
Propionate is generally
recognized as a mid-level
choice, offering good protection
and value.
ANSI Z87.1+, which we hope
will be adopted by OSHA as well,
also mandates that face shields and
head gear be tested together for effectiveness
before use. This is good news for safety
professionals and employees alike because
it offers more comprehensive protection, knowing
the headgear and faceshield are designed to
work as a unit.
Welding helmets are designed to provide protection
for the eyes and face from optical radiation
and weld spatter. Manufacturing safety standards
are outlined by ANSI Z87.1. Today, there are two
types of helmets. A passive helmet has a standard
polycarbonate or hardened glass filter lens with
shades ranging from 4 (the lightest) to 14 (the
darkest) and remains stable throughout the welding
process. Auto-darkening helmets can be purchased
in a single shade or variable shade range with various
features such as delay, sensitivity, and grind
modes. More than 60 percent of the industry uses
auto-darkening welding helmets today.
Whether for the eyes, head or face, PPE has
undergone significant improvements over the
past several years. As the industry looks to a
robust
2010, it
is important
that
every safety
officer
maintain risk management
activities
that properly
protect this industry’s
most valuable resource —
its people.
