2.4 Exposure Incidents & Universal/Standard Precautions

Two Related but Distinct Standards

PSI outline item A.4 covers "procedures for exposure incidents," explicitly citing Standard/Universal Precautions, OSHA, and the CDC as the tested reference points. Michigan enforces this through MIOSHA General Industry Safety and Health Standard, Part 554: Bloodborne Infectious Diseases, which mirrors the federal OSHA Bloodborne Pathogens Standard (29 CFR 1910.1030) that Part 554 was patterned after.

Universal (Standard) Precautions, Defined

Michigan rule R 325.70005 states the core principle directly: universal precautions must be observed to prevent contact with blood and other potentially infectious materials, and if it is difficult or impossible to tell body fluid types apart, every body fluid must be treated as potentially infectious. In practice, this means a cosmetologist never pauses to judge how "risky" a particular fluid looks — a small speck of blood from a nick during a shave, a client's tears, or an unidentified fluid are all treated with the exact same protective response.

Engineering and Work-Practice Controls

Part 554 requires two layers of protection working together:

• Engineering controls — physical safeguards that isolate or remove the hazard, such as sharps disposal containers and self-sheathing (safety) razors
• Work-practice controls and personal protective equipment (PPE) — behaviors and gear that reduce exposure when engineering controls alone are not enough, such as wearing gloves and washing hands immediately after glove removal

Key work-practice rules tested on the PSI exam include:

• Wash hands and any exposed skin with soap and water as soon as feasible after removing gloves or other PPE
• Wear gloves whenever there is a reasonable chance of contact with blood, other potentially infectious material, mucous membranes, or non-intact skin
• Never wash or reuse disposable (single-use) gloves; replace them immediately if contaminated, torn, or punctured
• Never eat, drink, apply cosmetics or lip balm, or handle contact lenses in a work area with a reasonable likelihood of exposure
• Contaminated sharps must go straight into closable, leakproof, puncture-resistant, labeled containers — never sheared, bent, recapped, or resheathed by hand

Step-by-Step: Responding to a Blood Exposure Incident

The PSI theory exam favors ordered, procedural questions. A defensible salon sequence looks like this:

1. Stop the service immediately the moment blood or another body fluid appears
2. Put on gloves (or fresh gloves, if already wearing contaminated ones) before touching the area
3. Control the injury — apply pressure with a clean, disposable material until bleeding stops
4. Clean and bandage the client's injury, referring to first aid or medical care if warranted
5. Discard contaminated single-use materials (gauze, cotton, disposable files) in a properly labeled waste container
6. Disinfect or sterilize every tool and surface the blood contacted — a tool that penetrated skin during the incident must be sterilized, not merely disinfected
7. Remove and dispose of gloves properly, then wash hands and any exposed skin immediately
8. Resume the service only after the area, tools, and technician's hands are fully decontaminated — or discontinue the service if the client's condition requires it

Exposure Control Plan and Employer Duties

Part 554 requires every covered employer to maintain a written exposure control plan that identifies job tasks with exposure risk and documents the engineering controls, PPE, and schedule used to comply with the standard. A working cosmetologist is not personally required to author the establishment's plan, but the PSI exam expects you to recognize that one must exist and that it must be reviewed and updated to reflect current tasks and procedures.

Hepatitis B Vaccination and Post-Exposure Follow-Up

Part 554 also requires employers to make the hepatitis B vaccination series available at no cost to any employee with occupational exposure, within 10 working days of initial assignment to exposure-risk duties. An employee may decline the vaccine, but must sign a waiver acknowledging the risk, confirming the vaccine was offered free of charge, and confirming it remains available at no cost later if the employee changes their mind while still in an at-risk role. If an actual exposure incident occurs — for example, a client's blood contacting the technician's broken skin — the employer must provide a confidential medical evaluation and follow-up at no cost, including documentation of how the exposure occurred, collection and testing of blood with consent, and counseling on the risks and benefits of further testing.

Documentation Matters on the Exam, Too

Beyond the physical response, PSI expects candidates to know that an exposure incident is documented, not just cleaned up and forgotten — including which employee was involved, the route of exposure, and the circumstances under which it occurred. This record supports both the injured party's medical follow-up and the salon's ongoing exposure control plan.

Why This Ties Back to Universal Precautions

Every rule in this section flows from the same premise stated in R 325.70005: you cannot know, just by looking, whether a fluid carries HBV, HIV, or another bloodborne pathogen. Universal precautions remove the guesswork — treat every incident the same way, every time, regardless of the client or how minor the exposure looks.
