Preparing
for Communication Access During Power Outages:
Equipment Needs
By Dana Mulvany
People with hearing loss are especially
at risk of losing communication access during power
outages since the devices we use for communication
access generally require power in some form.
Here are some suggestions for equipment that
can help preserve your ability to receive information
about emergencies and to communicate with others.
Universal power supplies (UPSes). UPSes
are often used as a temporary source of power for computers
(to keep them running long enough so they can be shut
down properly) but they can be used for other devices,
such as AC-powered telephones or TTYs. (If you have
a desktop computer, it's a very good idea to use a
UPS with the computer so you will not lose your work
during unexpected power outages.)
Surge protectors. Important and expensive
equipment, such as TVs, computers and adaptive equipment
should be protected from power surgesthat can be caused
by lightning storms. (Many UPSes also have surge protection
built in.)
Battery back-up capability. When shopping
for AC-powered equipment such as certain amplified
phones, VCO phones, TTYs, or alerting technology, consider
whether the equipment has battery back-up capability
if the power goes out. Also, if the equipment uses
a rechargeable battery or batteries, can standard batteries
be used if the existing batteries cannot be recharged
right away?
Battery-powered equipment. You may want
to consider getting battery-powered equipment, either
in place of or to supplement AC-powered equipment.
For example, are you considering whether to get a laptop
computer or a desktop computer? A laptop computer will
be easier to power from different sources, such as
vehicles. Some laptop computers are designed to have
an especially long battery life and may also have the
option of additional high-capacity batteries. (Computers
can also be used for making Internet Relay calls, and
thus are an alternative to TTYs.)
Alternative sources of light. People with more
severe hearing loss generally need light at night in
order to understand other people. Although flashlights
are important, a source of light that will illuminate
people's faces without needing to be held will be much
easier to use. Oil lamps and candles need to be handled
very carefully to avoid fire (first ask yourself whether
the people or pets in your house might easily knock
them over). Some kinds of lights are much more efficient
with battery power than others -- the label may indicate
this information.
Wireless pagers and phones. Most wireless
devices, including wireless phones, now allow two-way
communication by e-mail. Some also provide access to
customized web pages designed for a small screen. Generally,
text communication seems to require less power than
voice communication. Some wireless phones can be used
as modems for computers or hand-held devices, thus
potentially providing full access to the Internet.
Because most emergencies are now reported over the
Internet by text, Internet access can be very useful
for researching accessible information about emergencies.
Wireless devices are also an effective way of quickly
being notified about emergencies wherever you are (unless
you happen to be in an area that is not covered by
the service). Some of the new wireless phones have
been designed to work with new portable TTYs and thus
can also meet text-based telecommunications needs.
Power inverters for cars. Suppose you
have an important device with rechargeable batteries
that can't use other kinds of batteries, and the power
has been out for a couple of days. One thing you may
be able to do is to buy a power inverter so that you
can charge the device while you're driving. You will
need to make sure the power inverter has enough wattage
to handle the device you want to charge.
Note: be careful about powering devices from one's
vehicle. Never run your vehicle (or gasoline-powered
generator) in a standing position inside a garage or
if the exhaust pipe is blocked by snow. Carbon monoxide
fumes from the car are odorless and injure or kill
people. Running the car for a long time in a standing
position may also drain the car's battery.
Portable power supplies. These are often
used to jump start a car with a dead battery, but some
can power AC-powered devices or devices with a cigarette
lighter adapter. Costco and Sam's have been sources
of such power supplies, but possibly automotive stores
will also have similar products. Some may also have
a built-in light.
Gasoline-powered generators or solar-powered
chargers. Both are expensive but for some people,
will be worth the peace of mind. Gasoline-powered
generators are often very noisy. Solar-powered chargers
generally have a high up-front cost but there may
be special tax incentives in some states for installing
them in a residence. Follow the safety instructions
carefully for the gas-powered ones.
9-inch TVs with closed captioning capability. Nine-inch
TVs require less power than larger TVs, and many come
with a cigarette lighter adapter. Although nine-inch
TVs are not required to have closed captioning, some
manufacturers have included this functionality anyway.
(We do not have a comprehensive list of nine-inch TVs
with closed captioning and because models change quickly,
we suggest asking store representatives which nine-inch
TVs have this capability.) Such TVs can be a useful
method of receiving local information if you have alternate
sources of power for them such as those mentioned above.
Are You Prepared? Checklist for Power Outages
If the power goes out in my home:
- Do
I still have an effective way of calling people?
- Will
I be able to understand local emergency information
from my local government?
- Will
I be able to get understandable news updates from
news stations and other sources?
- Do
I have lighting sources to let me speechread people's
faces in the dark?
- Do
I have enough batteries to power my hearing aid(s)
and/or cochlear implant processors for several weeks?
Taking extra measures to preserve your communication
access during power outages now could save your life
and others in the future, ease stress for you during
a difficult time, and give you peace of mind. Good
luck!
