SECTION 1: INFECTION CONTROL & SANITATION (12 Questions)
Q1: A lash artist completes a full set application. Which sanitation procedure is required for
stainless steel tweezers before the next client according to TDLR and OSHA standards?
A. Wipe with alcohol pad and air dry
B. Rinse with water and store in closed container
C. Immerse in EPA-registered tuberculocidal disinfectant for the manufacturer's specified
contact time (typically 10-15 minutes), rinse, dry, and store in clean, covered container
[CORRECT]
D. Spray with disinfectant and wipe clean
Correct Answer: C
Rationale: TDLR requires all non-porous tools that contact clients to be disinfected between
clients using EPA-registered disinfectants with tuberculocidal, bactericidal, virucidal, and
fungicidal claims. Stainless steel tweezers must be fully immersed for the full contact time
specified by the disinfectant manufacturer (typically 10-15 minutes). Simply wiping (Option A)
or spraying (Option D) doesn't provide sufficient contact time for pathogen destruction. Rinsing
alone (Option B) provides no disinfection. Proper disinfection prevents transmission of
bloodborne pathogens (HBV, HCV, HIV) and bacterial infections between clients, as required by
OSHA Bloodborne Pathogens Standard 29 CFR 1910.1030 and TDLR Title 16, Part 4, Chapter
83.
Q2: Which item used during lash extension application is classified as single-use and must be
properly discarded after each client?
A. Stainless steel lash tweezers
B. Jade stone adhesive palette
C. Micro-swab used to apply primer or adhesive remover [CORRECT]
D. Reusable under-eye gel pads
,2
Correct Answer: C
Rationale: Micro-swabs (microfiber applicators, microbrushes) are classified as single-use items
because they cannot be properly cleaned and disinfected between clients without compromising
their structure and function. TDLR regulations and infection control standards require disposal of
single-use items after each client in a lined trash receptacle. Options A and B are non-porous
tools that can be disinfected and reused. Option D (reusable gel pads) must be thoroughly
cleaned and disinfected between clients if designed for reuse, though most lash artists use
disposable hydrogel pads for optimal hygiene. Reusing single-use items violates Universal
Precautions and risks cross-contamination.
Q3: What is the required contact time for an EPA-registered intermediate-level disinfectant to
effectively kill Mycobacterium tuberculosis on non-porous lash tools?
A. 30 seconds to 1 minute
B. 10-15 minutes (or per manufacturer's label instructions) [CORRECT]
C. 30 minutes minimum
D. 2 hours for complete sterilization
Correct Answer: B
Rationale: EPA-registered tuberculocidal disinfectants (intermediate-level) require specific
contact times to achieve claimed efficacy against Mycobacterium tuberculosis, the most resistant
vegetative bacteria. Most products require 10 minutes of wet contact; some newer formulations
require 3-5 minutes. The lash artist must follow the specific manufacturer's label instructions for
contact time, concentration, and compatibility with tools. Contact time begins when the item is
fully immersed and ends when removed for rinsing. Option A is insufficient for tuberculocidal
claims. Option C exceeds typical requirements. Option D describes sterilization (not required for
lash tools) rather than disinfection.
Q4: A lash artist accidentally cuts a client's skin while removing an outgrown extension with
tweezers. Which procedure is required?
A. Continue service and apply lash sealant to the area
B. Stop service immediately, apply pressure with clean gauze to stop bleeding, don fresh
gloves, clean area with antiseptic, apply bandage if needed, disinfect contaminated tools
and surfaces, document incident, and follow blood spill procedures per OSHA
[CORRECT]
C. Wipe blood with tissue and continue with new set
D. Have client wash eye and return next day
, 3
Correct Answer: B
Rationale: Any break in skin integrity constitutes an exposure incident under OSHA Bloodborne
Pathogens Standard. The artist must stop service immediately to prevent further injury and
exposure. Standard first aid (pressure, cleaning, bandaging) is followed by proper cleanup:
disinfecting tools (re-immersion), cleaning contaminated surfaces with EPA-registered
disinfectant, and disposing of contaminated materials (gauze, gloves) as regulated waste if
dripping blood present. Documentation is required for worker's compensation and liability.
Continuing service (Options A, C) violates infection control and safety standards. Option D
inadequately addresses immediate bleeding and contamination risks.
Q5: Which personal protective equipment (PPE) is required for lash artists during application to
comply with OSHA standards regarding adhesive fumes and potential splashes?
A. Nitrile gloves and optional protective eyewear (goggles or safety glasses with side shields)
when working with adhesives [CORRECT]
B. Surgical mask and latex gloves only
C. Face shield and double gloves for all clients
D. No PPE required for non-invasive procedures
Correct Answer: A
Rationale: OSHA requires PPE appropriate to hazards present. Nitrile gloves are mandatory to
prevent skin contact with cyanoacrylate adhesives (can cause allergic sensitization and bonding
of skin). While lash application is not invasive, protective eyewear is recommended when
working with chemical adhesives that can generate fumes or accidental splashes. Latex gloves
(Option B) are discouraged due to allergy potential and inferior chemical resistance to
cyanoacrylates. Full face shields (Option C) are excessive for standard application but may be
used if splashing risk exists. Option D violates OSHA General Duty Clause and TDLR sanitation
requirements.
Q6: Where should clean, disinfected tweezers be stored to maintain sanitation standards?
A. In the artist's pocket or apron
B. In a clean, dry, covered container labeled "clean" or "disinfected," separate from
dirty/used tools [CORRECT]
C. Mixed with used tools in a disinfectant solution
D. On the work station next to adhesive
Correct Answer: B
