Given the dynamic nature of most industrial
facilities, safety managers might feel like
they’re aiming at moving targets when they
seek to address the many variables that can
lead to workplace hazards. Without question, the
first line of defense is personal protection equipment
(PPE). However, PPE is only effective when an
employee selects the correct type and size and uses it
consistently.
Since industrial workers still run the risk of injury,
any comprehensive safety plan must also include emergency
eyewash or drench showers anywhere there is
a potential hazard from corrosives, toxic chemicals or
flying debris. In fact, OSHA requires suitable drenching
facilities in any area where the eyes or body may
be exposed to injurious corrosive materials.
How can you determine whether an emergency fixture
is needed and where it should be located? A thorough
safety tour that includes a detailed walk-through
of each workstation can help safety managers address
hazards that can be dangerous and costly for both the
worker and the organization.
Guidelines for evaluating job sites
During a walk-through, it is essential to reference
the American National Standards Institute (ANSI)
Z358.1–2004 emergency equipment standard. This
standard outlines the specific requirements for emergency
eyewash and drench shower equipment
installation, testing, performance, maintenance,
training and use.
ANSI requires that fixtures be installed
within 10 seconds reach of each hazard, which
translates to about 55 feet. The equipment
must be on the same level at which the user is
working and on the same level as the potential
hazard. If there are any doors between the hazard
and the fixture, the doors must swing in the
direction of the worker’s travel. At sites with
strong acids or caustics, the equipment should
be placed immediately adjacent to where the
exposure could occur.
Jobsite evaluations should not be a one-time
event. Annual inspections are required to ensure
that the right equipment is readily available and
working.
Identify hazards
When evaluating hazards, think in terms of
the following three categories:
1. Dangerous liquids — Many kinds
of liquids, even those that may seem innocuous,
can cause serious injuries to the face or eyes.
Think of the acronym STUD to remember the
different situations in which liquids can pose a
threat in your workplace:
- Storing
- Transferring
- Using
- Disposing
Bleach, acids, boiler chemicals, pesticides
and solvents are liquids commonly handled and
stored. All require emergency washing equipment
as part of an emergency preparedness plan. In
thinking about your facility, is there a 55 gallon
drum of a chemical being stored in the warehouse?
What about cleaners on a shelf in a janitorial
closet or a solvent used to clean equipment?

2. Activities that end in ‘ing’ — Many
hazards on worksites are related to actions. When
employees are performing physical activities, debris
and matter move around. Look for the different action
verbs that end in ‘ing’ to identify potential hazards,
such as:
- Welding
- Painting/staining
- Chipping
- Blowing
- Oiling
- Sanding
3. Activities where PPE is in use —
If PPE is being used, it means there is a hazard which
may require an emergency fixture within easy access.
Employees in hazardous situations are required to wear
ANSI-approved eye protection and clothing, but a
worker could remove protective gear to leave a job site
while co-workers are still working or could take off
goggles to inspect something — and an injury occurs.
Emergency fixtures can help treat and minimize injury
when PPE fails or when people fail to use it.
Assess emergency needs
After identifying potential hazards, determine if the
existing emergency equipment meets
the facility’s needs or, if none is
present, determine what type and
how many emergency fixtures are
needed. Workstations may need
to be relocated when applications
change, which is why re-evaluations
are important.
Choose equipment based on the
level of worker exposure and the
number of workers affected. For
example, evaluate a specific chemical
and the process of using it to
determine whether an eyewash,
eye/face wash, drench shower
or combination drench shower/
eyewash is most appropriate. In
general:
- Eyewash is effective for spills
or splashes likely to affect only the
eyes.
- Eye/face wash is designed to
be used when the entire face is at
risk.
- Drench showers are used to
quickly flush a larger portion of the
body but are not appropriate for the eyes.
- Combination eyewash and drench showers are
designed to flush the eyes and rinse larger areas of
the body.
Workers sanding surfaces who are not wearing
eye
protection
can easily
get contaminants
lodged in
their eyes. This
situation calls for
plumbed or portable
eyewash units. Individuals
splashed with a corrosive
chemical or exposed to an airborne
toxic gas need access to a
drench shower to rinse their entire
body. If both the eyes and body are
at risk, make sure a combination drench
shower and eyewash is available.
Injuries to the eye are the most common
preventable cause of blindness. The first few
seconds of an emergency are critical because
after 10 seconds of contact, the chances for a full
eye recovery are slim. Therefore,
immediately flushing the eyes at an
ANSI-compliant eyewash station is
crucial.
Eliminate obstacles and obstructions
Ideally, emergency equipment
will be used infrequently, but this
infrequent use often leads to the
area being used for storage, thus
creating clutter that prohibits
workers from quickly reaching
the equipment. Be sure to remove
any objects that block the emergency
station and check that fixtures
are easily identified. Draw
attention to emergency fixtures
by applying brightly colored tape
on the floor to mark off the area
or by painting footsteps on the
floor leading to the unit.
ANSI mandates that areas containing
emergency fixtures be
well-lighted and specifies that
each fixture must have a highly
visible sign for quick identification. Selecting fixtures
with a safety-yellow coating helps ensure visibility
in an emergency.
Consulting with a third-party safety consultant
and/or an emergency equipment product
manufacturer
can also
help eliminate
obstacles standing
in the way of a solid
safety plan. Some manufacturers
conduct free
job-site evaluations to assist
with ANSI compliance issues.
Meeting with experts and implementing
a strategy for installing,
maintaining, testing and training
employees about equipment use
can provide valuable peace of mind
for all.
