Question 1

A demolition contractor's designated first-aid responders completed bloodborne pathogens training on June 5 of last year. In March of this year, the contractor assigns the same responders to a new task: cleaning up and disposing of sharps-contaminated debris from a vacated clinic, a task they have never performed and which creates new exposures. The safety technician plans to simply wait for the regularly scheduled refresher in the following June. What does the standard require?

Answer: C. Additional training on the new exposures must be provided now because the new task changes their occupational exposure; the regular annual refresher is still due within one year of their previous training

The standard requires additional training when new tasks or procedures affect an employee's occupational exposure, and that training may be limited to the new exposures. The annual refresher is separate and must still occur within one year of the previous training, so waiting for June alone is not compliant.

“Employers shall provide additional training when changes such as modification of tasks or procedures or institution of new tasks or procedures affect the employee's occupational exposure. The additional training may be limited to addressing the new exposures created.”
Question 2

A clinic employee is about to start a shift in which she will draw blood from walk-in patients. The clinic manager says that precautions will be used only for patients who disclose a bloodborne infection or are known to have one, since "the rest are probably fine." The clinic's written Exposure Control Plan is to be built on the Universal Precautions approach. Which response correctly applies that approach to this practice?

Show answer and source

Answer: B. The practice is not consistent with Universal Precautions, because all human blood and certain body fluids are treated as if known to be infectious, regardless of the patient's disclosed status.

Universal Precautions means all human blood and certain body fluids are treated as if known to be infectious for HIV, HBV, and other bloodborne pathogens, so a patient's disclosed or unknown status cannot decide whether precautions apply. Limiting precautions to documented infections, visible skin contamination, or post-test confirmation contradicts that approach.

“According to the concept of Universal Precautions, all human blood and certain human body fluids are treated as if known to be infectious for HIV, HBV, and other bloodborne pathogens.”
Question 3

An outpatient clinic completed its annual review of the written Exposure Control Plan five months ago. Last week it created a new phlebotomy technician position, whose duties include drawing blood. The plan does not list this position, and no exposure incidents have occurred. What does the standard require the clinic to do?

Show answer and source

Answer: C. Update the plan now to reflect the new position with occupational exposure, even though the annual review is not yet due

The standard requires the plan to be updated whenever necessary to reflect new or revised employee positions with occupational exposure, in addition to the annual review. Waiting for the annual cycle is wrong because the new position triggers an update on its own.

“The Exposure Control Plan shall be reviewed and updated at least annually and whenever necessary to reflect new or modified tasks and procedures which affect occupational exposure and to reflect new or revised employee positions with occupational exposure.”
