It may be a jungle out there, but inside isn’t always
a safe haven, either — especially in work settings
where chemicals, gases and other hazardous
materials pose potential threats to life, limbs, eyes,
skin and other body parts. According to the Bureau
of Labor Statistics, nonfatal injuries in the workplace
declined only slightly between 2006 and 2007, from
4.1 million cases in 2006 to 4 million in 2007. Half
were serious enough to require absences from work,
job transfers or restrictions.
Providing a safe work environment is not only
an employer’s moral and regulatory obligation, it’s
also in a company’s best interest. Beside any liability
concerns, companies that are lax about providing
safe work environments risk ruining their reputations
whenever the public learns about preventable workplace
accidents.
Role of emergency fixtures
The effects of accidents can be diminished by
installing emergency fixtures throughout critical areas
where hazardous materials are used and stored.
Companies must make sure all employees are
aware of the location of those fixtures and trained in
their use. Employers must test emergency equipment
weekly to ensure they are installed correctly, working
properly and meet federal standards.
Emergency equipment should not be modified. Not
only does this void the warranty, it could diminish the
unit’s performance or render the equipment inoperable
in an emergency, and subject your institution to fines
and sanctions.
Getting started
Worksite assessment: If your workplace
uses chemicals or other hazardous materials, place
abundant emergency fixtures such as drench show-ers or
eyewash
equipment at
or near every
location.
Location, location, location:
The ANSI
Z358.1-2004 emergency
equipment standard states
that fixtures be installed within
10 seconds’ reach of each hazard,
or within about 55 feet. Where
strong acids or caustics are used,
place the equipment immediately next to
where the exposure could occur.
Clear identification: Emergency
fixtures must be plainly visible. ANSI mandates
that areas containing emergency fixtures be welllit
and specifies that each fixture has a highly visible
sign for quick identification. Selecting fixtures with a
safety-yellow coating helps ensure they will be easily
located in an emergency.
Cut the clutter: In an ideal world, emergency
fixtures will never have to be used — but there’s always
the risk that they will be needed, and quickly. Workers
often forget or overlook emergency equipment, and may
even use the areas around these fixtures to store boxes
and equipment. Make sure your emergency fixtures are
visible and accessible quickly when they are needed.
Cut any clutter, which can be distracting.
Check water requirements:
Emergency fixtures must have an adequate water supply
at an appropriate pressure and temperature.
- Water Flow Rate and Velocity —
For both drench showers and eyewashes, a minimum
water pressure of 30 pounds per square inch (PSI)
should be supplied to the unit. It must also satisfy the
ANSI minimum flow rate, which is at least 20 gallons
per minute (GPM) for drench showers, 0.4 GPM
for eyewashes and 3.0 GPM for eye and face washes.
Actual flow rates vary by product, so consult with the
equipment manufacturer to verify flow rates. Water
supply to the unit must be sufficient to support a full
15-minute flow of flushing fluid.
- Water temperature — ANSI requires
that a 15-minute flow of tepid water be supplied to
emergency equipment and suggests an incoming water
temperature between 60°F and 100°F. Thermostatic
mixing valves (tmvs) blend hot and cold water to a
specific set point and are an effective solution for delivering
tempered water to emergency fixtures.
Train and test: Establish a solid emergency
response plan that clearly defines the different types
of hazards on the job site and spells out the actions to
take in an emergency.
Train everyone on what constitutes an emergency
and whether a drench shower or eyewash unit is most
appropriate for a particular situation. Then give each
person an opportunity to test the equipment so he
feels comfortable activating it.
Test the equipment regularly. To ensure that your
emergency fixtures will work when they’re needed, follow
ANSI
guidelines
for
weekly and
annual testing.
Selection considerations
When space is tight: If space is at a premium,
look for emergency
fixtures specially designed for
tight areas, such as barrier-free
drench shower and recessed-mounted
eyewash units. Some models feature
a recessed shower handle that activates
the valve when pushed downward.
Privacy concerns: If an employee
is splashed with a hazardous substance, he or
she must quickly disrobe to completely flush all
the chemicals or contaminants from the skin. In a
mixed-gender environment, this may make injured
workers hesitate to use a drench shower.
An effective way to address privacy is to install
curtains around drench showers or combination
shower and eyewash units. Some manufacturers offer
vinyl laminate privacy curtains that resist chemicals
and mildew. Look for a high-visibility curtain, and
use a durable stainless steel curtain rail and mounting
brackets for strong, corrosion-resistant support.
Outdoor settings: If you’re in the construction
business, you often need portable emergency
fixtures that can operate outdoors — even when
temperatures plummet or where plumbed water is not
available.
Manufacturers offer a variety of portable emergency
equipment that can be used as a first response.
Workers can get immediate first-aid relief from
gravity-fed portable and stainless steel pressurized
eyewashes. Each design can provide a 15-minute continuous
flush.
Gravity-fed portable eyewashes are easy to fill,
assemble and transport when properly secured — and
they meet the ANSI Z358.1 standard. Stainless steel
portable pressurized fixtures are ideal for industrial
environments that require corrosion-resistance and
durability. These versatile fixtures also allow for the
attachment of a drench hose to rinse small areas of
the
body.
Finally,
even the most
conscientious
companies can
experience serious on-the-
job injuries. Make
sure you’re equipped to
respond quickly, with the
proper emergency and safety
equipment in place, easily visible
and ready to work in seconds.
