1. When applying the hierarchy of controls, which of the following is
considered the most effective method for controlling a workplace hazard?
A. Personal Protective Equipment B. Administrative Controls C. Engineering
Controls D. Elimination Rationale: Elimination is the most effective control
method because it physically removes the hazard from the workplace,
thereby completely mitigating the risk of exposure. Other methods like
engineering, administrative, and PPE only reduce the risk or control
exposure to an existing hazard.
2. A safety professional is calculating the potential severity of a fall. According
to the hierarchy of control effectiveness, which action should be prioritized
first? A. Designing a guardrail system to prevent the fall. B. Implementing a
fall arrest system. C. Creating a written procedure for working at heights. D.
Requiring harnesses for all employees. Rationale: Engineering controls like
guardrails are prioritized over administrative or PPE solutions because
they provide a permanent, passive safety measure that protects workers
without relying on behavioral compliance. Fall arrest systems and PPE are
lower on the hierarchy as they rely on equipment integrity and proper
usage.
,3. What is the primary purpose of conducting a Job Safety Analysis (JSA)? A. To
discipline employees for unsafe behavior. B. To determine the insurance
premiums for a department. C. To identify hazards associated with each
step of a task. D. To replace the need for formal safety training. Rationale:
A JSA is a systematic process that breaks down a job into individual steps
to identify potential hazards and determine the necessary controls to
mitigate them. It serves as a foundational tool for safety training and risk
assessment, not for performance management or insurance calculations.
4. Which regulatory agency is responsible for enforcing workplace safety
standards in the United States? A. Environmental Protection Agency (EPA)
B. Occupational Safety and Health Administration (OSHA) C. National
Institute for Occupational Safety and Health (NIOSH) D. National Safety
Council (NSC) Rationale: OSHA is the federal regulatory body mandated by
the OSH Act of 1970 to establish and enforce safety and health standards
for workplaces in the United States. NIOSH provides research and
recommendations, but does not have regulatory enforcement authority.
5. When assessing noise exposure levels, at what decibel level (TWA) must an
employer implement a hearing conservation program under OSHA
standards? A. 80 dBA B. 85 dBA C. 90 dBA D. 95 dBA Rationale: OSHA's
Hearing Conservation Amendment requires that a hearing conservation
program be implemented for employees whose noise exposure equals or
exceeds an 8-hour time-weighted average (TWA) of 85 decibels. This
threshold triggers requirements for monitoring, training, and audiometric
testing.
6. Which type of fire extinguisher is most suitable for a fire involving electrical
equipment? A. Water-based (Class A) B. Foam (Class B) C. Carbon Dioxide
(Class C) D. Dry Chemical (Class D) Rationale: Class C extinguishers are
designed specifically for fires involving energized electrical equipment
because the extinguishing agent is non-conductive and leaves no residue,
protecting the equipment and the operator from shock. Water and foam
can conduct electricity and pose significant danger.
, 7. According to the "Swiss Cheese Model" of accident causation, what is the
primary role of safety barriers? A. To eliminate all human error. B. To
prevent the alignment of "holes" in systemic defenses. C. To replace all
active management oversight. D. To ensure no accidents ever occur in the
organization. Rationale: The Swiss Cheese Model posits that while
individual defenses have weaknesses (holes), a well-designed safety
system ensures that these holes do not align, preventing a latent failure
from resulting in a catastrophic incident. It acknowledges that human
error exists and focuses on system resilience.
8. What is the main characteristic of a "leading indicator" in safety
performance metrics? A. It measures past accidents and injuries. B. It
measures proactive activities to prevent future incidents. C. It focuses
exclusively on insurance claim costs. D. It only tracks compliance with
previous citations. Rationale: Leading indicators are proactive, predictive
measures, such as the number of safety audits conducted, training
sessions completed, or hazard reports generated. They provide insight into
the effectiveness of safety management efforts before an incident occurs,
unlike lagging indicators which track past events.
9. Which ergonomic factor is most closely associated with the development of
Cumulative Trauma Disorders (CTDs)? A. Occasional lifting of heavy objects.
B. High repetition of tasks over long periods. C. Proper workstation
lighting. D. Periodic short breaks during a shift. Rationale: Cumulative
Trauma Disorders arise from repetitive physical stresses that exceed the
body's ability to repair itself over time. Repetition, force, and awkward
postures are key contributors, whereas proper ergonomics and breaks are
designed to mitigate these risks.
10.When handling hazardous chemicals, what is the most important document
to review for first aid procedures? A. The company's internal safety
newsletter. B. The manufacturer’s marketing brochure. C. The Safety Data
Sheet (SDS). D. The facility’s emergency evacuation map. Rationale: The
Safety Data Sheet (SDS) is the standardized document provided by
