OSHA 10 Module 2: Personal Protective Equipment, Bloodborne Pathogens, and Universal Precautions

Why PPE and Universal Precautions Matter in Early Childhood Settings

Preschool classrooms are busy places where diaper changes, wound care, and unexpected body-fluid spills happen every day. OSHA's Bloodborne Pathogens standard establishes the principle that you must treat every person's blood and certain other body fluids as potentially infectious — every time, with every child and adult. This approach is called universal precautions. In early childhood settings, universal precautions overlap with a broader concept called standard precautions, which also covers non-bloody body fluids such as vomit, saliva, and nasal secretions. Understanding both terms prepares you for real work and for your CDA credential.

The Chain of Infection

Disease spreads only when six links form a complete chain:

1. Infectious agent — the pathogen (virus, bacterium, etc.)

2. Reservoir — where the pathogen lives (a person, surface, or object)

3. Portal of exit — how it leaves the reservoir (blood, feces, respiratory droplets)

4. Mode of transmission — contact, droplet, or airborne spread

5. Portal of entry — how it enters a new host (mucous membranes, broken skin, mouth)

6. Susceptible host — a person with insufficient immunity

Breaking any single link stops infection. PPE, hand hygiene, and proper disinfection each break one or more links. As a preschool teacher you are both a potential host and a potential reservoir, so protecting yourself also protects children.

Selecting the Right PPE

Not every task calls for the same PPE. Match your protection to the hazard:

• Diapering or wound care: Disposable nitrile gloves are the minimum. Latex gloves are avoided because of latex allergy risk to children and staff. Choose a glove size that fits snugly — loose gloves tear; tight gloves restrict movement.
• Cleaning a body-fluid spill (vomit, blood, feces on a surface): Add a disposable apron or gown and, if there is any risk of splashing, protective eyewear (goggles or a face shield).
• Respiratory illness situations: Follow current public-health guidance, which may require a mask.

Never reuse single-use gloves. Inspect gloves before donning; discard any that are torn or have pinholes.

How to Don and Doff Gloves Without Self-Contamination

Donning (putting on):

1. Perform hand hygiene first (wash with soap and water for at least 20 seconds, or use alcohol-based hand rub if hands are not visibly soiled).

2. Open the glove package without touching the outside of the gloves with bare hands.

3. Slide each glove on, adjusting for a snug fit.

Doffing (taking off) — this is the highest-risk moment:

1. Pinch the outside of one glove at the wrist with the other gloved hand.

2. Peel the glove off so it turns inside-out; hold it in the still-gloved hand.

3. Slide two bare fingers under the wrist of the remaining glove.

4. Peel it off inside-out over the first glove, forming a glove-inside-glove bundle.

5. Drop the bundle directly into a lined waste container — do not set it on any surface.

6. Perform hand hygiene immediately.

The key rule: only glove touches glove; skin never touches the contaminated outside surface.

The CFOC4 Diapering Procedure

Caring for Our Children, Fourth Edition (CFOC4), published by the American Academy of Pediatrics and the American Public Health Association, is the national health and safety performance standard for early care. It describes a 10-step diapering procedure. The steps cover: preparing the changing area, putting on gloves, placing the child safely, removing the soiled diaper and cleaning the child, disposing of waste, removing and disposing of gloves, cleaning and sanitizing the changing surface, performing hand hygiene, recording the change, and washing hands again. Working through each step aloud during practice helps you internalize the sequence so it becomes automatic under the pressure of a crying child.

Key safety points within the procedure:

• Never leave a child unattended on a changing table, even for a second — falls are a leading cause of injury.
• Bag soiled diapers in a sealed, plastic-lined receptacle inaccessible to children.
• The changing surface must be sanitized between every child.

Preparing a Disinfectant Solution for Body-Fluid Spills

Dilute bleach (sodium hypochlorite) solution is a commonly used, low-cost disinfectant for body-fluid spills on hard, non-porous surfaces. CFOC4 and the product label together guide the correct concentration. Always read the product label first because bleach products vary in concentration. Mix fresh solution daily — bleach degrades quickly, especially in sunlight or heat — and label the container with the contents, concentration, date mixed, and hazard warning.

Safe handling rules:

• Wear gloves and eye protection when mixing and applying bleach solution.
• Mix in a well-ventilated area; never mix bleach with ammonia-based cleaners or any other chemical — toxic gases can result.
• Store bleach and all cleaning products in a locked cabinet out of children's reach, as required by licensing regulations.
• Rinse surfaces that children will contact after the disinfectant has had adequate contact time.

Hand Hygiene: The Single Most Effective Infection-Control Step

Handwashing with soap and running water is required before and after every diaper change, after removing gloves, after handling waste, before food preparation, and after outdoor play. Alcohol-based hand rub is an acceptable substitute when hands are not visibly soiled, but soap and water must be used after toileting, diapering, or contact with feces.

Connecting to Your Credentials

The CDA credential assessment evaluates competency in keeping children healthy and safe, including proper sanitation and infection control. State childcare licenses require programs to follow health and safety standards — including documented cleaning and sanitation procedures — as a condition of legal operation. Demonstrating the skills in this lesson makes you both credential-ready and legally compliant on day one of work.
