Infection Control, OSHA Bloodborne Pathogens, and Standard Precautions

Why Infection Control Comes First

Before you draw a single drop of blood, you must understand how to protect yourself and your patient from infection. Phlebotomy puts you in direct contact with blood and other potentially infectious materials (OPIM) every shift. OSHA's Bloodborne Pathogens Standard (29 CFR 1910.1030) is the federal regulation that sets the minimum requirements your employer must follow—and that you must follow—to reduce that risk. Violations can cause serious illness or death. For that reason, this lesson must be completed and passed before any hands-on collection practice begins.

The OSHA Bloodborne Pathogens Standard: Key Requirements

The Standard applies to any worker who can reasonably anticipate contact with blood or OPIM on the job. As a medical assistant performing phlebotomy, you are covered. The Standard organizes employer and employee duties into five areas:

1. Exposure Determination. Your employer must identify job classifications and tasks that involve occupational exposure—without regard to whether PPE is used. Medical assisting and phlebotomy are both listed as at-risk roles in most exposure-determination plans.

2. Engineering Controls. These are physical devices that remove or isolate the hazard. Examples include safety-engineered needles with retractable or shielding mechanisms, needleless IV systems, and puncture-resistant sharps containers. Engineering controls are the first line of defense and must be used whenever they are available.

3. Work Practice Controls. These are changes in how tasks are performed to reduce exposure. Key work practice controls in phlebotomy include:

• Never recap a used needle using two hands. The one-hand scoop technique is the only acceptable recapping method when recapping is necessary.
• Activate the needle's safety device immediately after withdrawal from the patient—before you reach for anything else.
• Dispose of sharps directly into a puncture-resistant, leak-proof sharps container; never overfill a container beyond the fill line.
• Wash hands with soap and water (or use an alcohol-based hand rub when hands are not visibly soiled) before and after every patient contact and after removing gloves.
• Never bend, shear, or break contaminated needles.

4. Hepatitis B Vaccination (HBV). Employers must offer the HBV vaccine series at no cost to employees who have occupational exposure. You have the right to decline, but you must sign a declination form. Accepting the vaccine is strongly recommended; hepatitis B can be transmitted by exposure to a very small amount of blood.

5. Post-Exposure Follow-Up. If a needlestick, cut, or splash to mucous membranes occurs, you must report it immediately to your supervisor. Your employer is required to provide confidential medical evaluation and follow-up at no cost. Time is critical: some post-exposure interventions are most effective within hours of exposure.

Standard Precautions

Standard Precautions, established by the CDC, treat all blood and most body fluids as potentially infectious, regardless of a patient's known or unknown diagnosis. This is not an assumption that every patient is sick—it is a recognition that you cannot always know a patient's infectious status. Standard Precautions include:

• Hand hygiene before and after patient contact
• Use of appropriate PPE based on anticipated exposure
• Safe injection and sharps practices
• Respiratory hygiene and cough etiquette
• Proper handling and disposal of contaminated materials

Selecting the Right PPE

PPE creates a barrier between you and infectious material. For routine venipuncture, nitrile gloves (latex-free to protect patients and staff with latex allergies) are required at minimum. Escalate PPE when the situation demands it:

| Situation | Minimum PPE |

|---|---|

| Routine venipuncture | Nitrile gloves |

| Patient is coughing or has known respiratory illness | Gloves + surgical mask |

| Risk of splash or spray (e.g., arterial draw, trauma) | Gloves + mask + eye protection or face shield |

| Isolation precautions in effect | Follow posted isolation signage; may add gown |

Donning order: Hand hygiene → gown (if needed) → mask → eye protection → gloves.

Doffing order (removes contamination from the outside in): Gloves → eye protection → gown → mask → hand hygiene. Remove gloves by grasping the outside of one glove, peeling it off, then using the clean inner surface of the removed glove to peel off the second glove. Never touch the outside of a used glove with bare skin.

Sharps Safety

Needlestick injuries are among the most common occupational exposures in health care. Prevent them by:

1. Using safety-engineered devices and activating the safety mechanism with one hand as soon as the needle is withdrawn.

2. Never passing an uncapped needle hand to hand.

3. Placing the sharps container at or near the point of use—never walk across a room with an exposed needle.

4. Using the one-hand scoop technique only if recapping is required: place the cap on a flat surface, slide the needle in with one hand, then flip the cap upright without using your other hand.

5. Disposing of the entire assembly (needle, holder, or syringe) intact into the sharps container—do not disassemble.

Safety Checkpoint

A 100% pass rate is required on the sharps-disposal and PPE donning/doffing checklist evaluated by your instructor. Any unsafe act observed during this practice session will stop your progress to hands-on labs until the skill is corrected and re-demonstrated successfully. Patient safety and your own safety are not negotiable.
