1. What is the primary purpose of a workplace safety program?
A. To increase production speed
B. To prevent injuries, illnesses, and property damage
C. To reduce employee benefits
D. To eliminate all workplace rules
Answer: B. To prevent injuries, illnesses, and property damage
Rationale:
The fundamental purpose of workplace safety programs is to identify
and control hazards before they cause harm. Effective programs protect
employees and others while also reducing equipment damage,
operational disruptions, and associated costs.
2. Which of the following is considered a hazard?
A. A condition or activity with the potential to cause harm
B. An employee's paycheck
C. A completed safety inspection
D. A safety meeting
Answer: A. A condition or activity with the potential to cause harm
Rationale:
A hazard is anything that has the potential to cause injury, illness,
,property damage, or other loss. Examples include exposed electrical
conductors, unguarded machinery, hazardous chemicals, excessive
noise, and unsafe work practices.
3. What is the first step in controlling a workplace hazard?
A. Purchase personal protective equipment
B. Identify the hazard
C. Discipline the employee
D. Increase production
Answer: B. Identify the hazard
Rationale:
A hazard cannot be effectively controlled until it is recognized. Hazard
identification involves observing the workplace, reviewing incident
information, inspecting equipment, and evaluating work procedures.
4. Which control is generally considered most effective in the
hierarchy of controls?
A. Personal protective equipment
B. Administrative controls
C. Elimination
D. Warning signs
Answer: C. Elimination
Rationale:
The hierarchy of controls generally ranks controls from most to least
effective: elimination, substitution, engineering controls,
administrative/work-practice controls, and PPE. Eliminating the
hazard removes the source of risk entirely.
,5. What is an example of an engineering control?
A. Wearing safety glasses
B. Installing a machine guard
C. Conducting employee training
D. Posting a warning sign
Answer: B. Installing a machine guard
Rationale:
Engineering controls physically isolate workers from hazards. Machine
guards, ventilation systems, barriers, and interlocks are common
examples. PPE and training depend more heavily on worker behavior.
6. Why should near misses be reported?
A. They are required only after someone is injured
B. They can identify hazards before an injury occurs
C. They automatically result in employee discipline
D. They have no safety value
Answer: B. They can identify hazards before an injury occurs
Rationale:
A near miss is an incident in which injury or damage could have
occurred but did not. Investigating near misses can reveal weaknesses in
procedures or controls and provides an opportunity to correct hazards
before a more serious event occurs.
7. Which action is safest when a worker discovers an unsafe
condition?
, A. Ignore it if no one has been injured
B. Report it and take appropriate action to prevent exposure
C. Wait until the next annual inspection
D. Continue working without notifying anyone
Answer: B. Report it and take appropriate action to prevent
exposure
Rationale:
Prompt reporting allows the hazard to be evaluated and controlled.
Depending on the situation, the worker may also need to stop work,
isolate the hazard, warn others, or notify a supervisor.
8. What is the main purpose of a job hazard analysis (JHA)?
A. To determine employee salaries
B. To identify hazards associated with individual job steps
C. To replace all employee training
D. To determine vacation schedules
Answer: B. To identify hazards associated with individual job steps
Rationale:
A JHA systematically breaks a job into steps, identifies hazards
associated with each step, and determines appropriate controls. It helps
organizations prevent injuries by addressing hazards before work begins.
9. Which of the following is a common ergonomic hazard?
A. Repetitive motion
B. Proper lighting
C. Emergency exits
D. Safety training
