Free CHSP Hazardous Materials Management Questions and Answers 1 — Questions and Answers
Question 1: A hospital pharmacy is disposing of several partially used vials of warfarin with a concentration of 1%. According to the EPA's Resource Conservation and Recovery Act (RCRA), how must this specific pharmaceutical waste be managed?
- As a P-listed acute hazardous waste. (Correct answer)
- As a U-listed toxic hazardous waste.
- As standard regulated medical waste (red bag waste).
- As a characteristic hazardous waste for toxicity (D-code).
Correct answer: As a P-listed acute hazardous waste.
Warfarin at concentrations greater than 0.3% is classified by the EPA as a P-listed acute hazardous waste (P001). This classification subjects the waste to the most stringent RCRA management standards, including lower quantity accumulation limits for determining generator status.
Question 2: A healthcare facility is reviewing its Hazard Communication Program. According to OSHA's standard (29 CFR 1910.1200), which of the following is a mandatory section within the standardized 16-section Safety Data Sheet (SDS) format?
- Section 9: Physical and chemical properties
- Section 4: First-aid measures
- Section 8: Exposure controls/personal protection
- All of the above (Correct answer)
Correct answer: All of the above
OSHA's Hazard Communication Standard requires a specific 16-section format for all Safety Data Sheets. All the options listed—Section 4 (First-aid measures), Section 8 (Exposure controls/personal protection), and Section 9 (Physical and chemical properties)—are required sections that provide critical safety information to employees.
Question 3: An employee in the oncology pharmacy accidentally drops and breaks a vial of a liquid cytotoxic drug, resulting in a small spill on the floor. After alerting others and securing the area, what is the MOST appropriate immediate action for the trained responder to take?
- Quickly wipe up the spill with paper towels from the nearest dispenser.
- Don the appropriate chemotherapy-specific Personal Protective Equipment (PPE) from a designated spill kit. (Correct answer)
- Pour a bleach solution over the spill to neutralize the drug.
- Complete an incident report before starting the cleanup process.
Correct answer: Don the appropriate chemotherapy-specific Personal Protective Equipment (PPE) from a designated spill kit.
The immediate priority in any hazardous material spill response is the safety of the responder. Before any cleanup attempt, the individual must don the appropriate PPE, which for cytotoxic drugs typically includes double gloves, a non-permeable gown, eye protection, and respiratory protection. This is a critical step to prevent occupational exposure. Using standard paper towels is insufficient, bleach can have dangerous reactions, and documentation occurs after the immediate hazard is controlled.
Question 4: A hospital laboratory must ship a patient's sputum specimen, which is suspected to contain *Mycobacterium tuberculosis*, to a reference lab for diagnostic testing. How should this specimen be classified for shipment under Department of Transportation (DOT) regulations?
- As an Exempt Human Specimen since it is for diagnosis.
- As a Category B Infectious Substance, UN 3373. (Correct answer)
- As a Category A Infectious Substance, UN 2814.
- As Regulated Medical Waste, UN 3291.
Correct answer: As a Category B Infectious Substance, UN 3373.
Under DOT regulations, an infectious substance transported for diagnostic purposes that is not in a form capable of causing permanent disability or fatal disease in healthy humans is classified as a Category B Infectious Substance, UN 3373. While a *culture* of Mycobacterium tuberculosis would be classified as Category A, a patient specimen for diagnosis falls under the less stringent Category B requirements.
Question 5: Which of the following is the primary factor that determines a healthcare facility's hazardous waste generator status (e.g., Very Small, Small, or Large Quantity Generator) under the EPA's Resource Conservation and Recovery Act (RCRA)?
- The number of licensed patient beds.
- The total amount of hazardous waste generated in a calendar month. (Correct answer)
- The proximity of the facility to a licensed treatment, storage, and disposal facility (TSDF).
- The total volume of chemical inventory maintained on-site.
Correct answer: The total amount of hazardous waste generated in a calendar month.
The EPA categorizes hazardous waste generators based on the quantity of hazardous waste they produce in a calendar month. For example, generating more than 1,000 kg of hazardous waste or more than 1 kg of acutely hazardous waste per month typically classifies a facility as a Large Quantity Generator (LQG), which has the most stringent regulatory requirements.
Question 6: A hospital's laboratory conducts initial air monitoring for formaldehyde and finds employee exposures are at 0.6 ppm as an 8-hour time-weighted average (TWA). According to the OSHA Formaldehyde standard (29 CFR 1910.1048), what is the employer now required to do?
- Repeat the monitoring within 6 months.
- Mandate the use of respirators for all employees in the area.
- Initiate periodic exposure monitoring and implement a medical surveillance program. (Correct answer)
- Label the area as a 'Danger, Formaldehyde, Cancer Hazard' zone.
Correct answer: Initiate periodic exposure monitoring and implement a medical surveillance program.
The OSHA Formaldehyde standard has an 'Action Level' of 0.5 ppm. When initial monitoring shows exposures at or above this level, the employer is required to begin periodic monitoring and establish a medical surveillance program for exposed employees. Respirators are mandated at the higher Permissible Exposure Limit (PEL) of 0.75 ppm, and specific danger signs are also required when the PEL is exceeded.
