answers the most frequently asked questions about these instruments, how to maintain them, and what to do in the unlikely event that a mercury spill should occur.
Please read this manual thoroughly and retain for future reference.
PREVENTIVE MAINTENANCE
Because the mercury units do not rely on moving parts such as metal bellows,
diaphragms, gears, or other sources of mechanical wear, only an occasional inspection of the instrument is recommended.
A regular program of preventive maintenance will extend the life of your sphygmomanometer. The program should include the following simple inspection steps:
1. The mercury level in the graduated plastic tube should be at the “0”
calibration mark with the inflation system disconnected and the mercury unit in
a vertical position.
Note: If the mercury level is below “0”, readings over the entire scale will vary only the
difference between the mercury level and the “0” calibration.
2. Airflow should be tested by partially inflating the instrument to observe the
rising column of mercury, and then slowly deflating - stopping the column at
several points - to observe the falling column.
The diaphragm filter should be replaced if the mercury does not rise easily in
the tube, or if the mercury column bounces noticeably.
Note: The diaphragm filter is designed to dampen oscillations of the mercury during
inflation and deflation while preventing escape of the mercury. If clogged due to
accidental over inflation, it may require replacement.
3. The graduated plastic tube should be clean. If it is streaked with mercury which
has oxidized, the tube and mercury should be cleaned as described in this booklet.
4. The inflation system, consisting of the ADCUFF
ADFLOW™valve can be tested for air leaks.

, inflation bladder, bulb, and
with another twist tie or rubber band closure.
5. Place the double polybagged and wrapped unit inside the packing case,
or inner carton.
6. Arrange some cushioning bags or more bubble wrap around the mercurial
unit to protect it from excessive shifting.
7. If returning two or three mercurial units, repeat steps 1-6 as necessary. We
suggest packaging each of the mercurial units in separate inner cartons that
can fit into the packing case.
8. Seal the packing case closed with a strip of adhesive tape. Carefully place the
specially authorized return address label to the top of the box.
9. Ship via UPS Prepaid Ground Service ONLY. No other carriers are authorized
use for safe return of mercury instruments.
What is a Material Safety Data Sheet (MSDS)? Why do I need it and how do I
get one?
A MSDS sheet is required by OSHA. All medical locations require you keep it on
file. A MSDS provides you with information about mercury, and what protective measures you have to do for your safety. Your ADC dealer will provide you with the
MSDS upon request.

REPAIRING MERCURY LEAKS
If a mercury leak exists at the top or bottom of the plastic tube, the silicone rubber
washers, which provide a seat for the ends of the plastic tube, should be replaced.
Remove the cartridge tube. Then use a small screwdriver to remove the old silicone
rubber washers, and replace with correct size new washer. Replace the graduated
plastic tube.
If a mercury leak exists at the bottom of the reservoir, see the following section
“How to Clean or Replace Mercury,” which includes steps for replacement of the
reservoir gasket.
After a mercury leak has been repaired, check the level of the mercury meniscus (the
top rim of the mercury column in the plastic tube). If it is below the “0” calibration, add
enough mercury to bring it up to the correct level. This is done by unscrewing the
knurled chrome cap at the top of the plastic tube and pouring a small amount of

mercury into the tube with the help of a small paper cone or funnel. The instrument
is then tipped in the direction of the reservoir and returned to a vertical position
before the new mercury level is observed. Repeat the process as necessary to bring
the mercury up to the “0” calibration mark.
How do I return a broken unit?
Regardless of whether or not the unit is intact (no mercury leakage) it may be
returned to ADC for service via UPS only (USPS does not authorize shipment of mercury). When returning an intact mercurial unit, be sure to include a note listing your
name, address, daytime phone number, and symptoms of the unit. When packing mercurial units for transport, be sure to follow the instructions in the “Packing and Shipping”
section below.
HOW TO CLEAN OR REPLACE MERCURY
When removing the mercury from an instrument we strongly suggest you wear
disposable rubber gloves and goggles. Be sure to remove all jewelry. Also, an inexpensive plastic storage box makes an excellent portable work station. Unscrew the
knurled cap at the top of the graduated plastic tube. Then carefully pour all the mercury
into a paper cup or glass container and tap reservoir in order to get all the mercury
out of the reservoir.
Roll a small cone of ordinary copy paper, leaving a small opening at the end of the

cone, and pour the mercury through this cone into another clean paper cup or glass
container. Repeat a few times. Residue will adhere to paper.
Remove the graduated plastic cartridge tube and clean it. The bore of the tube may be
easily cleaned with alcohol and a lint free pipe brush. The outside of the tube should also
be cleaned occasionally by wiping with a damp cloth.
Replace the graduated plastic tube and return the clean mercury to the instrument
through the opening at the top of the tube, using the paper cone described above.
Check the mercury level - it should be at the “0” line on the plastic tube with the
inflation system disconnected and the instrument in its correct position (vertical for
desk or wall mount models, 15° incline for mobile instruments). If some mercury has
been lost, add enough (through the top of the plastic tube) to bring the rim of the
mercury meniscus to the “0” calibration mark. Then replace the knurled cap at the top
of the graduated plastic tube, and screw it down firmly.

PACKING AND SHIPPING INSTRUCTIONS
Important Note: Failure to follow the proper packing and shipping instructions below
for mercurial return kits could result in mercury leakage during transit. The shipper will
be responsible for all costs associated with cleaning mercurial spills that were caused
by improper packaging and shipping methods.
You will be sealing each mercury unit in TWO polybags with bubble wrap in
between. Only pack a MAXIMUM of 3 units per return. (Assorted styles are acceptable) It is very important to note that the Department of Transportation (HAZMAT)
requirements will require special caution labels for any boxes that contain 1 pound
or more of mercury. Three mercurial units are below this 1 pound requirement, and
do not require any additional labeling.
1. Remove the inflation system, basket(s), rod, and base from all mercurial
units before packing and dispose of in accordance with local regulations.
ADC will ONLY accept the main mercurial units for return.
2. Put ONE mercurial unit in a polybag and seal it with a twist tie or
rubber band closure.

FAQ (FREQUENTLY ASKED QUESTIONS)
Why use mercury?
Mercury (Hg) is a liquid metal with very stable performance characteristics. As such,
mercurial blood pressure devices remain the internationally recognized standard for
accuracy. Because there are no moving parts, springs, needles, casings, or other components that may become defective or wear with age, mercury instruments are inherently
the most reliable and accurate. With minimal care and maintenance, these instruments
should last a lifetime.
What is so special about DIAGNOSTIX™ mercury instruments?
Our exclusive Safety First
that provide you with a level of protection no other mercurial instrument can match.
Unbreakable graduated plastic cartridge tube. Designed from space age polymers, the
tube exhibits remarkable performance stability. It will not crack, craze, or shatter. Yellowing, a problem that plagued first generation plastic tubes, is all but gone. Tolerances to .1mm assure measurement repeatability.
Reservoir Locking Switch secures the mercury safely in the reservoir during routine
maintenance, cleaning, or transport.
EZ Tube
™
System simplifies the safe removal of the cartridge tube or top cap filters
for cleaning or maintenance without risking a spill.
Is Elemental Mercury dangerous?
Yes, it can be. Once vaporized, the lungs readily absorb elemental mercury from
inhaled air. High level acute doses and lower level chronic doses are both causes for
concern.
If accidentally ingested, very small amounts of elemental mercury will not be
absorbed by the digestive system and will be excreted.
Some forms of mercury COMPOUNDS (not the type used in blood pressure instruments) are highly toxic and particularly dangerous. These should NOT be confused
with elemental mercury.
Because there is so little actual mercury in a mercurial blood pressure instrument,
the exposure to a spill or leakage, if properly and promptly contained, will generally
pose little if any health risk.
DIAGNOSTIX
™
Blood Pressure instruments use less than 2 ounces of 99.9999% pure
elemental mercury.
What should I do in the event of a spill?
First, isolate the area to prevent further contamination or spread of the spilled liquid.
Spilled mercury should be picked up at once since the mercury will vaporize rapidly
and may contaminate the surrounding air.
Larger spills involving the entire contents of the mercury instrument (about 2 oz.) may
be cleaned up with a commercially made mercury suction pump. Do not dry sweep or
use ordinary vacuum cleaners on floors exposed to mercury spills since this may produce additional hazardous vapors.
In the unlikely event of a spill, it will most likely involve very small amounts of just

Waste mercury should be placed in a tightly covered container and disposed of in
accordance with state and local environmental regulations.
As a convenience to our customers, we can help arrange returns to a waste reclamation facility. Contact our customer service department toll-free at 1-800-ADC-2670
for the necessary packaging supplies and return authorization.
Do not incinerate mercury or mercury compounds or dispose of down the drain.
Please note: Liquid mercury combines with many soft metals. Jewelry should be
removed prior to cleaning of instruments, or mercury spills. We also recommend the
wearing of latex gloves and protective eyewear when cleaning mercury spills.
What if a mercury spill should occur and I don’t have a spill kit?
Chances are that a spill kit is on the premises. Contact your building’s maintenance
department. However if you do not have one, they can be ordered from most laboratory safety supply houses. As a convenience to our customers, a basic spill kit can be
purchased directly from ADC. Call our customer service department toll-free at 1-800ADC-2670 and ask for ADC part number 980SK. We will be glad to rush one out to
you immediately.
Please note: As a precaution, we strongly recommend that you keep a mercury spill
kit on hand.
Doesn’t mercury spill all over the place?
A mercury spill can be cleaned up fairly easily. It rolls into one large bead. It can be
cleaned up with any commercially available mercury spill kit specifically designed for
this job. When spilled on a hard surface a simple soft bristled brush or a 3cc syringe
may even be used to collect very small amounts of mercury quickly and safely. Elemental mercury is a non-wetting liquid. It does not absorb into rugs or fabrics. It can
be removed quickly and completely from carpeted surfaces using a mercury
absorbent powder that reacts with mercury to form a harmless amalgam which can
then be easily contained.
Don’t I have to report mercury spills and put special hazardous markings on
the collection container?
No. Mercurial spills of less than one (1) pound are exempt from any Federal, State, or
local agency reporting requirements. According to DOT (Department of Transportation)
CR49. 173.164 no special markings of any kind are required when dealing with quantities
of LESS than 1 pound. ADC DIAGNOSTIX
™
instruments contain about 2 ounces of
99.9999% pure elemental mercury.
What should I do in the event of accidental eye contact with mercury?
Symptoms of eye exposure can include redness, pain, and watery eyes. If mercury contaminates the eyes, open the contaminated individual’s eyes while under gently running
water, using sufficient force to open eyelids. Have the contaminated individual “roll” their
eyes. Flush the contaminated individual’s eyes with running water for a minimum of 15
minutes and seek immediate medical attention.
a few drops of spilled mercury. These smaller amounts may be picked up with mercury
absorbent sponges or gently swept into a collection container using a soft bristled
DISPOSABLE brush. (Remember to dispose of the brush after use).
Carpet, crevices, and other difficult to clean areas may be cleaned using a mercury
absorbent powder that reacts with mercury to form a harmless amalgam.
The suction pump, sponges, and powder are available through laboratory and safety
supply companies.
