Section 1: OSHA Regulations, Rights, and Responsibilities (Q1-Q12)
Q1: A construction worker notices that a fellow employee is operating a circular saw without a guard in place.
Under OSHA regulations, which of the following is the worker's most appropriate course of action?
A. Ignore the situation since it is not their responsibility to monitor other workers
B. Report the hazardous condition to a supervisor immediately, as employees have the
right to a safe workplace [CORRECT]
C. Confront the coworker and physically remove the saw from their hands
D. Wait until the end of the shift to mention it to the foreman casually
Correct Answer: B
Rationale: Under OSHA, employees have the right to a safe workplace and the responsibility to report recognized
hazards. Option A violates the duty to maintain a safe environment; option C could create a more dangerous
confrontation; and option D delays correction of an immediate hazard, increasing the risk of injury.
Q2: Which of the following statements correctly describes the purpose of the Occupational Safety and Health
Administration (OSHA)?
A. To regulate wages and working hours for all employees in the United States
B. To assure safe and healthful working conditions for working men and women by setting
and enforcing standards [CORRECT]
C. To provide workers' compensation insurance for employees injured on the job
D. To issue professional licenses and certifications for construction tradespeople
Correct Answer: B
Rationale: OSHA was created by the Occupational Safety and Health Act of 1970 specifically to assure safe and
healthful working conditions. Wages and hours are regulated by the Department of Labor's Wage and Hour Division
(FLSA), workers' compensation is managed at the state level, and professional licensing is handled by state licensing
boards, not OSHA.
Q3: A worker at a construction site believes that OSHA safety standards are being violated and wants to file a
complaint. Which of the following employee rights under OSHA is most relevant to this situation?
A. The right to request an OSHA inspection and to be free from retaliation for exercising
safety rights [CORRECT]
B. The right to refuse any work assignment that the employee personally considers too difficult
C. The right to choose which PPE to wear based on personal comfort preferences

D. The right to shut down any construction site where a violation is suspected
Correct Answer: A
Rationale: OSHA guarantees workers the right to request inspections and protection from employer retaliation. Option
B is incorrect because refusal to work is only protected under imminent danger conditions, not personal preference.
Option C is incorrect because PPE selection is determined by the employer based on hazard assessment. Option D is
incorrect because only OSHA can officially shut down a site.
Q4: An employer at a commercial construction project must report a workplace incident to OSHA. A worker
suffered an inpatient hospitalization due to a fall from scaffolding. Within what timeframe must the employer
report this to OSHA?
A. Within 4 hours of the incident
B. Within 8 hours of the incident
C. Within 24 hours of the employer learning of the incident [CORRECT]
D. Within 72 hours of the incident
Correct Answer: C
Rationale: OSHA requires employers to report fatalities within 8 hours and inpatient hospitalizations, amputations, or
loss of an eye within 24 hours of the employer learning about the incident. The 8-hour window applies only to fatalities,
making option B incorrect for this scenario. Options A and D are not OSHA-mandated reporting timeframes.
Q5: Which OSHA recordkeeping form must be posted annually in a visible workplace location from February 1
through April 30?
A. OSHA 300 Log of Work-Related Injuries and Illnesses
B. OSHA 300A Summary of Work-Related Injuries and Illnesses [CORRECT]
C. OSHA 301 Injury and Illness Incident Report
D. OSHA 200 Log and Summary
Correct Answer: B
Rationale: The OSHA 300A Summary is the specific form that must be posted annually from February 1 through April
30. The OSHA 300 Log is the detailed log maintained throughout the year but is not the posted form. The OSHA 301 is
an individual incident report that is not posted publicly. The OSHA 200 form is obsolete and was replaced by the 300
Log.
Q6: During an OSHA inspection, an inspector arrives at a construction site without prior notice. Which of the
following statements is TRUE regarding OSHA inspections?
A. OSHA must provide at least 48 hours of advance notice before conducting any inspection
B. Employers can legally deny OSHA inspectors access to the worksite if no prior appointment was made
C. OSHA inspections are conducted without advance notice and can be triggered by
complaints, referrals, or planned inspections [CORRECT]
D. OSHA inspectors must obtain a search warrant before entering any private construction site
Correct Answer: C
Rationale: OSHA inspections are conducted without advance notice as a standard practice. This ensures that
workplace conditions are observed in their normal state. Advance notice is only given in exceptional circumstances.
Employers cannot deny access to OSHA inspectors, and while OSHA may obtain warrants if access is refused, they do
not require one as a default.
