1. According to the hierarchy of controls, which of the following is the most
effective method for managing workplace hazards? A. Administrative
controls B. Personal protective equipment (PPE) C. Engineering controls D.
Elimination Rationale: Elimination physically removes the hazard from the
workplace, making it the highest level of protection in the hierarchy.
Other options like engineering controls, administrative controls, and PPE
are secondary methods that do not remove the hazard itself.
2. Which regulatory agency is responsible for establishing and enforcing safety
standards in the United States? A. Occupational Safety and Health
Administration (OSHA) B. National Institute for Occupational Safety and
Health (NIOSH) C. Environmental Protection Agency (EPA) D. Mine Safety
and Health Administration (MSHA) Rationale: OSHA is the primary federal
agency responsible for setting and enforcing workplace safety and health
regulations. While NIOSH conducts research, it does not have the
authority to enforce standards.
3. What is the primary purpose of a Job Hazard Analysis (JHA)? A. To
determine employee salary based on risk B. To evaluate the cost-benefit of
safety equipment C. To identify potential hazards in a task and implement
controls D. To provide grounds for employee termination Rationale: A JHA
is a systematic process that breaks down a job into steps, identifies
, hazards associated with each step, and determines appropriate control
measures to mitigate those hazards.
4. Heinrich’s Domino Theory suggests that the primary cause of industrial
accidents is: A. Unsafe equipment B. Unsafe acts of persons C. Poor
management oversight D. Lack of training Rationale: Heinrich’s theory
postulates that the majority of accidents are caused by the unsafe acts of
persons, emphasizing human behavior as the primary factor in the
accident sequence.
5. In the context of fire protection, a Class C fire involves which of the
following? A. Ordinary combustibles B. Flammable liquids C. Energized
electrical equipment D. Combustible metals Rationale: Class C fires are
defined specifically as fires involving energized electrical equipment where
the use of a non-conductive extinguishing agent is necessary to prevent
electrical shock.
6. Which of the following is considered a trailing indicator of safety
performance? A. Number of safety meetings conducted B. Number of
hazard inspections completed C. Percentage of employees trained D. Lost-
time injury rate Rationale: Trailing indicators, such as injury rates,
measure the outcome of past performance, whereas leading indicators
measure proactive activities taken to prevent future incidents.
7. According to the Theory of Constraints, the throughput of a system is
limited by: A. The most efficient resource B. The total number of resources
C. The bottleneck or constraint D. Management decision-making Rationale:
The Theory of Constraints identifies the "bottleneck" as the limiting factor
that restricts the overall output or performance of an entire system.
8. What does the acronym PEL stand for in OSHA regulations? A. Potential
Exposure Limit B. Primary Effect Level C. Personal Evaluation Limit D.
Permissible Exposure Limit Rationale: PEL represents the maximum
amount or concentration of a chemical or physical agent to which a
, worker can be exposed over a specific time period (usually 8 hours)
without adverse health effects.
9. When conducting an accident investigation, the primary goal should be: A.
Identifying root causes to prevent recurrence B. Assigning blame to the
employee at fault C. Minimizing company liability and legal costs D.
Completing the necessary OSHA 300 logs Rationale: The objective of a
professional accident investigation is to identify systemic issues and root
causes to implement corrective actions, rather than focusing on punitive
measures.
10.Which of the following best describes the "Swiss Cheese Model" of accident
causation? A. Latent conditions and active failures align to allow a breach
in defenses B. Accidents are caused solely by individual human error C.
Accidents happen when management ignores safety rules D. Engineering
controls are always sufficient to prevent failures Rationale: The Swiss
Cheese Model illustrates that systems have layers of defense, and an
accident occurs when the "holes" in these defenses align, allowing a
hazard to pass through the barriers.
11.Which type of ventilation is preferred for removing airborne contaminants
at their source? A. General dilution ventilation B. Local exhaust ventilation
C. Natural ventilation D. Positive pressure ventilation Rationale: Local
exhaust ventilation captures contaminants directly at the point of origin,
preventing them from spreading into the general work environment,
making it more effective than dilution.
12.What is the main characteristic of a "Safety Culture"? A. Mandatory training
programs B. Shared values and beliefs regarding safety by all employees C.
High fines for safety violations D. Frequent use of PPE Rationale: Safety
culture refers to the collective commitment, shared values, and ingrained
attitudes that employees at all levels have toward safety, which drive
behaviors even when no one is watching.
