The start of the new year is the perfect
time to review the January 2009 revisions
to ANSI standard Z358.1-2009
for emergency eyewash. The ANSI
standard has always required that an appropriate
mechanism for flushing injured eyes be
present at the site of any hazardous material.
It mandates that eyewash be made available
within a 10-second walk of a hazard and that
an injured person flush his or her eyes for a
full 15 minutes. It also details how emergency
eyewash should be delivered: the rate of flow,
fluid angle, temperature, user’s position, and
station location, installation and maintenance.
Even though the risks of non-compliance
are costly, approximately half of all businesses
required to meet the ANSI standard remain in
non-compliance. The National Safety Council
reports that the average lost-time injury costs
nearly $30,000, and eye injuries that are not
properly treated can result in partial or complete
vision loss to an individual.
Employers who choose the proper eyewash
fluid and delivery system can reduce the severity
of eye injuries as well as the related costs. This
article will help you determine whether your
business needs to comply with ANSI’s eyewash
standard and how to do so in just five steps.
STEP ONE: Determine whether your site requires eyewash
The first step is to assess your facility for the
presence of eye hazards. As a rule, businesses are
required to have eyewash stations on the premises
if any of the following hazards are found:
- Paint
- Solvents
- Battery-charging stations
- Hazardous chemical storage
- Tool parts washers
- Chemical pumping/mixing areas.
Eyewash protection is likely to be required
as well if employees use:
- Chemical-resistant gloves
- Cartridge or air-supplied respirators
- Chemical-resistant goggles
- Flammable storage containers.
You may be surprised to learn that businesses
as common as hair salons, garden centers
and home goods centers require eyewash facilities
due to the presence of potentially harmful
chemicals. Refer to equipment manuals and material
safety data sheets (MSDS) on chemical packaging to
learn whether emergency eyewash is required because
of specific hazardous materials.
STEP TWO: Select the right eyewash for your needs
Planning how and where eyewash will be used
will help determine what type of delivery system is
best. What are the most common hazards? Does the
workspace layout change as new jobs commence?
Is plumbing readily available at the site of every eye
hazard? Once you have determined your needs, there
are two types of primary emergency eyewash delivery
stations to consider: plumbed and portable.
Plumbed eyewash units deliver plumbed tap water
to the eyes in plentiful amounts. However, they are
expensive to install, impractical to move and require
weekly maintenance. Furthermore, tap water has
proven to be detrimental in treating
injured eyes for many reasons.
Because its temperature is not easily
regulated, plumbed water is often
too hot or too cold to flush with for
the required 15 minutes. Since it
does not match the eye’s natural pH,
flushing can cause irritation. And
tap water often contains harmful
microorganisms or other contaminants
that can further damage an
already compromised eye. In fact, a
2008 Associated Press study found
that public drinking water for at least 41 million
Americans was polluted with chemical contaminants,
many of which can cause secondary injury and possible
vision loss. Plumbed stations also require the
most frequent maintenance; ANSI requires that they
be activated weekly to rinse harmful particle buildup
through pipes and to ensure proper water pressure.
Portable stations come in many varieties. They
contain water, saline solution or 100 percent sterile
saline, each of which is maintained at room temperature
inside the unit. Stations that deliver sterile
flushing fluid offer unmatched safety. Sterile saline
is the only emergency eyewash solution that must be
prepared in an FDA-approved cleanroom to assure
purity as well as pH and isotonic qualities that match
those of the human eye. Because it is devoid of harmful
impurities, sterile saline reduces employers’ risk
of liability if further injury results. Portable devices
that do not deliver sterile fluid still offer advantages
over plumbed units: their fluid is maintained at room
temperature, they require less maintenance and those
with buffered saline solutions more closely match
the pH of the eye. Self-contained portable devices
require less frequent maintenance, including cleaning,
disinfecting and changing the flushing fluid as often
as every three to six months as directed by the
manufacturer. Sealed cartridge devices containing
sterile or purified, buffered saline solution
require the least maintenance and remain free of
bacteria and contamination for up to 24 months.
STEP THREE: Make emergency eyewash accessible
An injured worker may have limited or no
vision while en route to the station, so it is
important to select a location for the unit that is
quickly and easily accessible during an emergency.
ANSI specifies that stations be located:
- Within a 10-second walk from the hazard
- On a travel path from the hazard that is
free of obstructions
- On the same level as the hazard
- Immediately adjacent to the hazard for
strong caustics and strong acids
- In an area that is well lit and identified with a
sign that is highly visible to everyone served by it.
STEP FOUR: Teach proper emergency response
It is the employer’s responsibility to ensure
that every employee is trained and proficient
in using emergency eyewash units. Employees
must know how to reach and activate the unit
and how to properly rinse contaminants from
their eyes. The proper flushing technique calls
for the worker to hold both eyes open with their
forefingers and thumbs and let the fluid rinse
across the eyes from the inside corner out for 15
minutes. The employee should be instructed to
seek follow-up medical care if needed.
STEP FIVE: Put eye safety into practice
The best way to ensure eyewash compliance in
the workplace is by building it into the company’s
safety plan. Employ a safety manager, assign
safety stewards or use a third-party vendor for
employee training and station maintenance. The
appointed safety leader should train staff regularly
as a group and new associates as they join. He or
she should also maintain eyewash units as required
according to ANSI and/or the manufacturer.
Emergency eyewash is an important — and
oftentimes required — part of a company’s
safety equipment. By following these five steps,
your business will not only comply with ANSI
safety standards — it will also reduce costs
related to eye injuries and provide a safer and
more productive work environment.
