CLC Regulatory Compliance & Safety Standards 2 — Questions and Answers
Question 1: Under OSHA's Bloodborne Pathogens Standard (29 CFR 1910.1030), how often must employers offer the hepatitis B vaccine to at-risk laboratory employees?
- At time of initial assignment to tasks involving potential exposure (Correct answer)
- Annually during flu season
- Every three years after initial hire
- Only after a documented exposure incident
Correct answer: At time of initial assignment to tasks involving potential exposure
The standard requires the hepatitis B vaccine series to be offered at no cost to employees within 10 working days of initial assignment to tasks with occupational exposure risk.
Question 2: Which regulatory body enforces the Clinical Laboratory Improvement Amendments (CLIA) in the United States?
- Centers for Medicare & Medicaid Services (CMS) (Correct answer)
- Food and Drug Administration (FDA)
- Occupational Safety and Health Administration (OSHA)
- Environmental Protection Agency (EPA)
Correct answer: Centers for Medicare & Medicaid Services (CMS)
CMS is responsible for CLIA program oversight, which regulates laboratory testing on human specimens to ensure accuracy, reliability, and timeliness of patient test results.
Question 3: A laboratory receives a new chemical with an unfamiliar hazard profile. Under OSHA's Hazard Communication Standard (HazCom), what must be present before lab personnel use the chemical?
- A Safety Data Sheet (SDS) accessible in the work area (Correct answer)
- Approval from the state health department
- A signed waiver from each employee
- A minimum 30-day review period by the lab director
Correct answer: A Safety Data Sheet (SDS) accessible in the work area
HazCom requires that an SDS be readily accessible to employees during each work shift for every hazardous chemical in the workplace before use begins.
Question 4: Under CAP accreditation requirements, what is the minimum retention period for quality control records in a clinical laboratory?
- 2 years (Correct answer)
- 6 months
- 5 years
- 10 years
Correct answer: 2 years
CAP requires that QC records be retained for at least 2 years, though some specific records (e.g., transfusion records) have longer retention requirements.
Question 5: When a laboratory's CLIA certificate of waiver is expired, what is the laboratory legally permitted to do?
- Perform only the waived tests listed on the expired certificate while awaiting renewal
- Perform no testing until the renewed certificate is received (Correct answer)
- Perform any testing as long as a renewal application is pending
- Continue all testing with increased QC frequency until renewed
Correct answer: Perform no testing until the renewed certificate is received
A laboratory must not perform any testing after its CLIA certificate expires; testing must cease until a valid certificate is issued.
Question 6: Which NFPA rating system is used on chemical labels to quickly communicate health, flammability, instability, and special hazard information in laboratory settings?
- NFPA 704 diamond (Correct answer)
- GHS pictogram system
- DOT placard system
- HMIS color bar system
Correct answer: NFPA 704 diamond
The NFPA 704 diamond uses a four-quadrant color-coded diamond with numeric severity ratings (0–4) for health (blue), flammability (red), instability (yellow), and special hazards (white).
Question 7: A laboratory consultant discovers that a facility has been disposing of chemical fixatives (e.g., formalin waste) down the drain. Which federal regulation is most directly violated?
- Resource Conservation and Recovery Act (RCRA) (Correct answer)
- Clinical Laboratory Improvement Amendments (CLIA)
- Health Insurance Portability and Accountability Act (HIPAA)
- Occupational Safety and Health Act (OSH Act)
Correct answer: Resource Conservation and Recovery Act (RCRA)
RCRA governs the generation, transportation, treatment, storage, and disposal of hazardous waste, and formalin waste must be properly characterized and disposed of as hazardous chemical waste.
