Free CHSP Hazard Control Practices Questions and Answers 1 — Questions and Answers
Question 1: A hospital is renovating a wing that is adjacent to a high-risk patient care area for immunocompromised patients. To MOST effectively control the hazard of construction dust and airborne pathogens from entering the patient care area, which of the following should be the primary intervention?
- Requiring construction workers to wear N95 respirators at all times.
- Installing temporary, sealed, hard-wall barriers and creating negative air pressure in the construction zone with HEPA-filtered exhaust. (Correct answer)
- Increasing the cleaning frequency of the adjacent patient care area and placing adhesive floor mats at the entrances.
- Providing surgical masks for patients to wear when they are outside of their rooms.
Correct answer: Installing temporary, sealed, hard-wall barriers and creating negative air pressure in the construction zone with HEPA-filtered exhaust.
The most effective hazard control method, according to the hierarchy of controls, is an engineering control that isolates the hazard. Installing sealed, hard-wall barriers and using negative pressure with HEPA filtration is a comprehensive engineering control that contains the hazard at its source, preventing it from migrating to patient care areas. The other options are administrative controls or PPE, which are lower on the hierarchy and less effective for controlling environmental hazards of this scale.
Question 2: A healthcare facility's safety committee is analyzing injury data and notes a high incidence of musculoskeletal disorders (MSDs) among nursing staff, primarily linked to patient repositioning. Which of the following initiatives represents a comprehensive ergonomic hazard control approach?
- Mandating annual training on 'proper body mechanics' for all nursing staff.
- Implementing a strict disciplinary policy for staff who do not use proper lifting techniques.
- Conducting a risk assessment and implementing a Safe Patient Handling and Mobility (SPHM) program that includes mechanical lifts and staff training. (Correct answer)
- Providing back support belts to all nursing staff and encouraging their use during patient handling tasks.
Correct answer: Conducting a risk assessment and implementing a Safe Patient Handling and Mobility (SPHM) program that includes mechanical lifts and staff training.
A comprehensive ergonomic approach involves a systematic process of identifying hazards, assessing risks, and implementing controls. A Safe Patient Handling and Mobility (SPHM) program that combines engineering controls (mechanical lifts) with administrative controls (training, policies) is the most effective strategy to reduce MSDs related to patient handling. Relying solely on 'proper body mechanics' training has been shown to be insufficient. Back belts are a form of PPE and are the least effective control measure, with limited evidence of effectiveness.
Question 3: During a routine safety inspection in a hospital's central sterile supply department, a safety professional observes an employee using a glutaraldehyde solution for cold sterilization without wearing any gloves or eye protection. What is the MOST appropriate immediate action for the safety professional to take?
- Immediately report the finding to the department manager to handle.
- Post a new sign reminding staff of the personal protective equipment (PPE) requirements.
- Stop the employee, instruct them to use the required PPE, and ensure they understand the risks and proper procedures. (Correct answer)
- Note the deficiency in the inspection report for later follow-up with the safety committee.
Correct answer: Stop the employee, instruct them to use the required PPE, and ensure they understand the risks and proper procedures.
The most appropriate immediate action is to intervene directly to stop the unsafe act and prevent potential harm to the employee. This involves stopping the work, ensuring the employee immediately uses the correct PPE, and providing on-the-spot education about the chemical hazards and required safety protocols. While reporting to the manager and documenting the finding are also necessary steps, they do not address the immediate risk to the employee.
Question 4: Which of the following is the primary purpose of conducting a proactive risk assessment in a healthcare setting?
- To assign blame for past safety incidents.
- To satisfy the requirements of insurance carriers.
- To reactively address hazards after an adverse event has occurred.
- To systematically identify and evaluate potential hazards before they cause harm, enabling the implementation of preventive controls. (Correct answer)
Correct answer: To systematically identify and evaluate potential hazards before they cause harm, enabling the implementation of preventive controls.
A proactive risk assessment is a forward-looking process designed to identify potential hazards and evaluate the associated risks before incidents occur. This allows an organization to prioritize and implement control measures to prevent harm to patients, staff, and visitors. The other options describe reactive, compliance-focused, or punitive approaches, which are contrary to the proactive and preventive nature of risk assessment.
Question 5: A hospital is implementing its Hazard Communication Program in accordance with OSHA standards. Which of the following is a key component required by this program?
- Developing a list of all non-hazardous chemicals used in the facility.
- Ensuring that Safety Data Sheets (SDSs) for hazardous chemicals are readily accessible to all employees. (Correct answer)
- Requiring employees to purchase their own personal protective equipment for handling chemicals.
- Conducting chemical safety training for management personnel only.
Correct answer: Ensuring that Safety Data Sheets (SDSs) for hazardous chemicals are readily accessible to all employees.
OSHA's Hazard Communication Standard (HCS) requires employers to ensure that information about chemical hazards is available and understandable to workers. A critical component of this is maintaining a library of Safety Data Sheets (SDSs) for every hazardous chemical and ensuring employees have unrestricted access to them in their work areas. Training is required for all exposed employees, not just management, and employers must provide necessary PPE.
Question 6: When selecting Personal Protective Equipment (PPE) for healthcare workers who will be in contact with a patient with a known airborne infectious disease, which factor is LEAST critical for the safety professional to consider?
- The specific mode of transmission of the disease.
- The brand name and cost of the PPE. (Correct answer)
- Proper fit and training for the healthcare worker on use and disposal.
- The level of protection offered by the equipment (e.g., N95 respirator vs. surgical mask).
Correct answer: The brand name and cost of the PPE.
While budget is a practical consideration, the brand name and cost of PPE are the least critical factors when it comes to worker safety. The primary considerations must be the effectiveness of the PPE for the specific hazard, which is determined by the mode of disease transmission, the level of protection the equipment provides (e.g., an N95 respirator is required for airborne precautions), and ensuring the worker is trained and the equipment fits correctly to provide a proper seal.
