1 - INTRODUCTION
The Safe-T-ShieldTM represents the next generation in extraoral
aerosol control for dentists, medical professionals and anyone with
a high exposure to oral vapor.
The Safe-T-Shield provides both a physical barrier to droplet, spray & bio-burden ejection as well
as aerosol evacuation via a patent pending laminar ow air manifold. The device uses a three-part
system to create an H13 level of ltration to capture 99.97% of particles down to .3 um. To maintain
suction and ltration performance, follow the lter replacement schedule on page 21.
While the protection o󰀨ered by the Safe-T-Shield is higher than any other extraoral system
available, the Safe-T-Shield is intended to be used in conjunction with a sensible PPE regime. The
requirements for such PPE use, including gloves, gowns, and masks will vary by region and need.
Users are cautioned to take every available measure to prevent the spread of aerosol and particulate
contamination.
For user safety and optimal performance, please read this Specication and User Guide thoroughly
prior to use.
Demonstration videos for assembly, use and cleaning are referenced throughout this guide
and may be found here in the “Demonstration Videos” tab on the Safe-T-Shield page at

5 - POSITIONING FOR TREATMENT
MOVING THE SAFE-T-SHIELD
When moving the Safe-T-Shield within the operatory or from one
treatment room to another, use the circular handle located at the top
of the Riser Tube (g. 5.1).
While the device is stable, please use caution to avoid tipping –
especially when rolling over uneven surfaces such as thresholds.
BASIC POSITIONING WITHIN THE OPERATORY
The Safe-T-Shield may be located on either side of the patient chair as shown below. For best results,
position the base no more than 24” away from the patient’s head. Distances greater than that may
cause strain on the adjustable Suction Tube and/or make it di󰀩cult to set the Shield at a proper height
above the oral cavity.
During 2-Handed use, you may want to place the unit on the clinician’s side of the patient to allow
easier adjustments of the Shield during treatment (g 5.2).
When used for 4-Handed procedures, we recommend placing the Safe-T-Shield on the assistant’s
side (g. 5.3).
In either case, be sure the unit is not obstructing the patient’s path on initial entry.

5 - POSITIONING FOR TREATMENT cont.
POSITIONING THE SHIELD ABOVE THE PATIENT
Ideal positioning may vary depending on user
preference and treatment requirements.
However, for optimal evacuation and protection from
spray and bioburden ejection, the Shield should be
located at a distance of 8” to 10” directly above the
oral cavity, and at a downward angle of approximately
20˚ as shown (g. 5.4).
To Adjust the Height and Location of the Shield Above the Patient:
Click here for a demonstration video or go to: www.ergonomic-products.com/safe-t-shield
After positioning the base next to the patient chair as needed (see gs. 5.2 & 5.3), follow the steps
below to properly position the Shield above the patient.
1. Place your open hand on the side of the Suction Tube away from you, and approximately 6” above
the circular Handle. Place your other hand on the top of the arch formed by the Tube (g. 5.5).
2. Use lower hand to steady and control the Suction Tube, while carefully bending the top away from
you, down, and toward the patient. Leave the Shield 12” to 15” inches above their face (g. 5.6).
3. Move to the patient's head, place a hand on each side of the Manifold and carefully articulate the
Shield into proper position, in line with the patient and 8"-10" above the oral cavity (g. 5.7).
8” -10”
5.4
Do not bend the Suction Tube immediately above the Handle as this may cause
undo strain on the Tube. Maintain at least 6” of straight Tubing above the Handle.
When establishing this initial “rough” position the Shield may settle, drifting
down 3”-4”. Do not attempt to achieve a nal position at this time.

6 - PROCEDURE TECHNIQUES AND SUGGESTIONS
When we say our products are “designed by dentists, for dentists” we mean it. Our founder and the
source of our industry-changing designs is Dr. David Ahearn, a practitioner with two thriving practices
in Massachusetts. While Dr. Ahearn’s experience-driven insights alone give us a unique position in
the eld, his practices allow us the opportunity to test our designs in live dental environments. We
test, we learn, we rene - and repeat the process to continuously bring you the highest quality, most
e󰀨ective products available.
RECOMMENDED INSTRUMENTS
In testing live procedures under the Safe-T-Shield, we found that angled HVE handpieces provided
the highest level of comfort and access to the oral cavity, while allowing the Shield to best perform it’s
critical task of controlling the aerosols generated in treatment (g. 6.1).
Some of our team hadn’t used these instrument variants before, but all adapted quickly and became
strong proponents.
The team’s reaction was so strong, in fact, that we felt obligated to include (at no charge) the
90O Bull Frog HVE handpiece shipped with your Safe-T-Shield. We encourage you to test the
instrument and see for yourself the benets it brings.
We also tested 45O ASI handpiece as well, and to great e󰀨ect.

6 - PROCEDURE TECHNIQUES AND SUGGESTIONS cont.
RECOMMENDED INSTRUMENTS cont.
We discovered a few other methods to optimize comfort and control without sacricing treatment
quality during Shield use.
Short HVE tips
Shorter HVE tips allowed better positioning. For instance,
assistants suctioning from the left, during treatment of posterior
upper left teeth.
Standard tips may be easily cut to any length desired, as shown
right. We recommend cutting to a length of approximately 4”.
Short handle mirrors
As we mentioned, we included a bag of short handle
mirrors with your shipment at no charge. Our team
found these to be very e󰀨ective in all cases.

7 - CLEANING AND DISINFECTION
For proper infection control, the exterior of all Safe-T-Shield components should be thoroughly
disinfected after each use. These include the Shield, Manifold, Airow Plate, Suction Tube and
Housing as detailed below. See page 20 for weekly cleaning procedures.
USE ONLY RECOMMENDED CLEANING COMPOUNDS AS DESCRIBED BELOW
RECOMMENDED DISINFECTION PRODUCTS
To more e󰀨ectively capture patient exhalations and generated aerosols, the Shield is formed with a
signicant downward curve. The most e󰀨ective material to create this form, while maintaining optical
clarity and patient safety, is PETG (polyethylene terephthalate glycol). While PETG is a very durable
material, some disinfectants in dental use may harm the nish or clarity of the Shield and Manifold.
Though other components of the Safe-T-Shield may be less susceptible to residue or fogging, we
recommend using only the cleaning solutions and disinfection products below on the entire unit to
avoid accidental contact with the Shield and Manifold.

As with all disinfection processes, follow your o󰀩ce’s standard protocols regarding PPE and other
guidelines.
After cleaning and disinfection, inspect the parts and components. Any pieces that appear worn,
cracked, or damaged should no longer be used. Contact us for repairs or replacement parts.
CLEAN & DISINFECT THE SHIELD, MANIFOLD AND AIRFLOW PLATE AFTER USE
1. Use an alcohol wipe to clean any large particulate matter or spray o󰀨 the Shield and Manifold. Let
air dry, approximately 1 minute.
2. Use an allowed disinfection solution and standard protocols to thoroughly disinfect both sides of
the Safe-T-Shield, both the exterior and interior of the Manifold, and the stainless steel Airow
Plate. Follow the disinfection manufacturer’s instructions for appropriate application.
While a clean Shield is obviously important for visual acuity, it is worth mentioning that the Airow
Plate is prominently in the patient’s view during treatment. To maintain a positive patient experience,
it is vital that this plate is not only thoroughly disinfected, but that it LOOKS as clean as possible, too.
An alcohol wipe is eective to remove any streaks or spotting from disinfection. Additionally, we oer
replacement Airow Plates should standard wear and tear degrade the appearance.
CLEAN & DISINFECT THE SUCTION TUBE AND LOWER ELEMENTS AFTER USE
1. If necessary, use an alcohol wipe to clean any large particulate matter or spray o󰀨 the Suction
Tube and lower elements of the Safe-T-Shield. Let air dry, approximately 1 minute.
2. Use an allowed disinfection solution/product and standard protocols to thoroughly disinfect the
Suction Tube, Handle and Riser Tube. Follow the disinfection manufacturer’s instructions for
appropriate application.
3. Follow applicable regulatory board protocols on cleaning & disinfection for equipment below the
chair level when addressing the Housing and Base. Again, use only allowable solutions/products
as listed.

WEEKLY CLEANING AND DISINFECTION
The Suction Tube Interior
In addition to cleaning and disinfection of the exterior elements of the Safe-T-Shield after each use,
we recommend disinfecting the interior of the Suction Tube weekly.
The best method for this is to employ a fogger using hypo-chlorous acid.
1. Remove the Shield from the manifold (see p. 10).
2. Remove the stainless steel Airow Plate from the manifold (see p. 11).
3. Follow your manufacturer’s instructions to prepare your fogger for use.
4. Turn on the Safe-T-Shield.
5. Place the fogger nozzle in the center of the Suction Tube
6. Fog the tube for 10 seconds only and stop. To avoid saturation of the Primary Cotton Filter, do not
run the fogger longer than the recommended 10 seconds.
7. Turn o󰀨 the Safe-T-Shield and replace the Airow Plate and Shield (see pp. 10 & 11).
The Airow Plate
The Airow Plate may be autoclaved. We recommend this weekly as well. See page 11 for
instructions on removal and re-installation of the Plate.
As previously mentioned, some clients prefer to have spare Airow Plates available for a quick swap
out should they require additional cleaning to maintain a pristine appearance.
