3.2 Hand Hygiene & Respiratory Etiquette

3.2 Hand Hygiene & Respiratory Etiquette

Hand hygiene is the single most effective action a phlebotomy technician can take to interrupt transmission of pathogens between patients, specimens, and the healthcare environment. Respiratory etiquette complements hand hygiene by limiting droplet and aerosol spread during coughs, sneezes, and close patient contact. AMCA PTC Tasks 2.01–2.02 expect you to apply WHO/CDC guidance consistently—not as a checklist performed once per shift, but as a habit timed to specific moments of care.

WHO/CDC Five Moments of Hand Hygiene

The World Health Organization (WHO) and Centers for Disease Control and Prevention (CDC) align on five critical moments when hand hygiene must occur. Memorize these moments by clinical sequence rather than by number alone:

In practice, a single draw often triggers several moments: before contact (Moment 1), before cleansing and puncture (Moment 2), after blood exposure and glove removal (Moment 3), and after leaving the chair or bedside (Moments 4–5). Skipping any moment creates a transmission opportunity that PPE alone cannot fix.

Soap and Water vs Alcohol-Based Hand Rub

Alcohol-Based Hand Rub (Preferred for Routine Use)

Alcohol-based hand rub (ABHR) containing 60% to 95% ethanol or isopropanol is the preferred method for routine hand hygiene when hands are not visibly soiled. Advantages include faster application, better compliance, and superior reduction of many vegetative bacteria and viruses compared with plain soap when used correctly.

Correct ABHR technique:

1. Apply product to dry hands in the manufacturer-recommended volume.
2. Rub all surfaces—palms, backs of hands, between fingers, thumbs, fingertips, and wrists—for at least 20 seconds until dry.
3. Do not rinse or wipe off product before it dries; incomplete drying reduces kill.

Soap and Water (Required Situations)

Plain or antimicrobial soap and water are required when:

• Hands are visibly dirty, soiled with blood or body fluids, or contaminated with proteinaceous material.
• Caring for patients with known or suspected Clostridioides difficile (C. diff) infection, or when spore-forming organisms are a concern (alcohol does not reliably kill spores).
• After using the restroom, before eating, or when ABHR is unavailable.
• Hands feel sticky or heavily soiled after multiple glove changes with powder or residue.

Correct soap-and-water technique: Wet hands with water, apply soap, scrub all surfaces for at least 20 seconds, rinse thoroughly, and dry with a disposable towel. Use the towel to turn off the faucet when possible to avoid recontamination.

Respiratory Etiquette

Respiratory (cough) etiquette reduces spread of influenza, RSV, COVID-19, and other respiratory pathogens in waiting areas and draw rooms.

Core Cough Etiquette Steps

1. Cover the mouth and nose with a tissue when coughing or sneezing.
2. If no tissue is available, cough or sneeze into the upper sleeve or elbow, not into bare hands.
3. Dispose of used tissues in a waste container immediately.
4. Perform hand hygiene after contact with respiratory secretions or contaminated tissues.
5. Maintain distance from others when symptomatic, and follow facility screening rules.

Phlebotomy areas should stock tissues, no-touch waste bins, and hand hygiene supplies at entrances and chairs. Posting visual reminders supports patient compliance, especially in outpatient labs where symptomatic individuals may wait near others.

Mask Use When Indicated

Masks are not required for every routine draw under standard precautions alone, but they are indicated when:

• The phlebotomist has respiratory symptoms and must continue essential work per facility policy.
• The patient is coughing, sneezing, or on droplet/airborne precautions.
• Facility policy requires source control during seasonal respiratory surges or outbreak periods.
• There is splash or spray risk during arterial sticks, difficult draws, or procedures involving body fluids near the face (face protection is covered further in PPE sections).

Surgical/procedure masks primarily block large droplets from the wearer’s mouth and nose. Fit and continuous wear matter: adjusting a mask with contaminated gloves defeats the purpose. Perform hand hygiene before donning and after doffing.

Common Exam Traps

• Trap: Choosing alcohol rub for a C. diff room because it is “faster.” Spores require soap and water plus contact precautions per facility protocol.
• Trap: Washing once at the start of the shift and relying on gloves. Gloves are not a substitute for hand hygiene; clean hands before donning and after doffing every pair.
• Trap: Re-contaminating clean hands by touching the faucet, phone, or tourniquet before the aseptic step. Moment 2 must occur immediately before the clean procedure.

Hand hygiene and respiratory etiquette are low-tech skills with high clinical impact. On the AMCA PTC exam and on the floor, correct timing and method selection matter more than memorizing brand names of products.
