Top 10 Questions for Decontamination Technician Interview

1. Describe the steps involved in decontaminating personal protective equipment (PPE)?

The steps involved in decontaminating personal protective equipment (PPE) include:

• Establish a designated decontamination area: The decontamination area should be located in a well-ventilated space and away from any potential hazards.
• Prepare the decontamination solution: The appropriate decontamination solution will vary depending on the type of PPE and the contaminants present. Follow the manufacturer’s instructions for preparing the solution.
• Remove any gross contamination: Use a brush or wipes to remove any visible dirt or debris from the PPE.
• Immerse the PPE in the decontamination solution: Submerge the PPE in the solution and allow it to soak for the recommended amount of time.
• Rinse the PPE thoroughly: Use clean water to rinse the PPE until all traces of the decontamination solution have been removed.
• Dry the PPE: Allow the PPE to air dry completely or use a fan or dryer to speed up the process.
• Inspect the PPE: Check the PPE for any damage or wear and tear. If any damage is found, the PPE should be discarded.

2. What are the different types of decontamination methods?

Physical methods

• Wiping: Using a clean cloth or sponge to remove contaminants from surfaces.
• Brushing: Using a brush to remove contaminants from surfaces.
• Vacuuming: Using a vacuum cleaner to remove contaminants from surfaces.
• Mopping: Using a mop and water to clean surfaces.

Chemical methods

• Disinfection: Using a chemical solution to kill microorganisms on surfaces.
• Sterilization: Using a chemical or physical process to kill all microorganisms on surfaces.

3. What are the safety precautions that should be taken when handling hazardous materials?

• Wear appropriate personal protective equipment (PPE): This includes gloves, goggles, a respirator, and a protective suit.
• Work in a well-ventilated area: This will help to prevent the inhalation of hazardous fumes or vapors.
• Handle hazardous materials carefully: Avoid spills and leaks. If a spill or leak does occur, clean it up immediately.
• Dispose of hazardous materials properly: Follow all local, state, and federal regulations for the disposal of hazardous materials.
• Be aware of the potential hazards of hazardous materials: This includes knowing the symptoms of exposure and the appropriate first aid measures.

4. What are the different types of radioactive contamination?

• Alpha contamination: This type of contamination is caused by alpha particles, which are large and heavy and cannot penetrate the skin.
• Beta contamination: This type of contamination is caused by beta particles, which are smaller and lighter than alpha particles and can penetrate the skin.
• Gamma contamination: This type of contamination is caused by gamma rays, which are electromagnetic waves that can penetrate the skin and internal organs.

5. What are the basic principles of radiation protection?

• Time: The less time spent in a radiation field, the lower the dose of radiation received.
• Distance: The further away from a radiation source, the lower the dose of radiation received.
• Shielding: Using lead or other materials to block radiation can reduce the dose of radiation received.

6. What are the different types of radiation detectors?

• Ionization chambers: These detectors measure the number of ions produced by radiation in a gas.
• Geiger-Mueller counters: These detectors use a gas-filled tube to detect radiation.
• Scintillation detectors: These detectors use a material that emits light when it is struck by radiation.

7. What are the potential health effects of radiation exposure?

• Acute radiation syndrome: This is a condition that can occur within hours or days of exposure to a high dose of radiation. Symptoms include nausea, vomiting, fatigue, and hair loss.
• Chronic radiation syndrome: This is a condition that can occur months or years after exposure to low doses of radiation. Symptoms include cancer, heart disease, and stroke.

8. What are the different types of radioactive waste?

• Low-level radioactive waste: This type of waste contains small amounts of radioactivity and can be disposed of in a landfill.
• Intermediate-level radioactive waste: This type of waste contains higher levels of radioactivity and must be disposed of in a special facility.
• High-level radioactive waste: This type of waste contains the highest levels of radioactivity and must be disposed of in a deep geological repository.

9. What are the different methods of radioactive waste disposal?

• Landfills: Low-level radioactive waste can be disposed of in landfills that are lined with special materials to prevent the release of radioactivity.
• Near-surface disposal facilities: Intermediate-level radioactive waste can be disposed of in near-surface disposal facilities that are located in remote areas.
• Deep geological repositories: High-level radioactive waste can be disposed of in deep geological repositories that are located in stable rock formations.

10. What are the challenges of radioactive waste disposal?

• The long-lived nature of radioactivity: Radioactive waste can remain radioactive for thousands of years, which makes it difficult to find a safe and permanent disposal solution.
• The potential for radioactive waste to migrate: Radioactive waste can migrate through soil and water, which can contaminate the environment and pose a health risk to humans.
• The high cost of radioactive waste disposal: The construction and operation of radioactive waste disposal facilities is expensive, which can make it difficult to find funding for these projects.

Decontamination Technicians are responsible for ensuring that hazardous materials are safely removed from equipment, surfaces, and other objects. They work in a variety of settings, including hospitals, laboratories, and industrial facilities. Key job responsibilities include:

1. Decontaminating Equipment and Surfaces

Decontamination Technicians use a variety of methods to decontaminate equipment and surfaces, including chemical disinfection, UV radiation, and heat sterilization. They must be familiar with the different types of hazardous materials that they may encounter and the appropriate decontamination procedures for each type.

• Follow established protocols for decontaminating equipment and surfaces to ensure the safety of personnel and the environment.
• Select and use appropriate decontamination methods based on the type of hazardous material present.

2. Monitoring Decontamination Processes

Decontamination Technicians must monitor decontamination processes to ensure that they are effective. They may use a variety of monitoring devices, such as chemical indicators, biological indicators, and radiation detectors, to verify that the decontamination process has been successful.

• Monitor decontamination processes to ensure that they meet established standards and regulations.
• Use monitoring devices to verify the effectiveness of decontamination procedures.

3. Maintaining Decontamination Equipment

Decontamination Technicians are responsible for maintaining the decontamination equipment that they use. They must ensure that the equipment is in good working order and that it is calibrated correctly. They may also be responsible for repairing or replacing decontamination equipment.
