Questions and Answers (Verified Answers)
Section 1: OSHA Regulations, Rights, and Responsibilities
Q1: Under the Occupational Safety and Health Act of 1970, what is the primary purpose of OSHA?
A. To enforce building codes and zoning regulations for construction projects
B. To assure safe and healthful working conditions for working men and women [CORRECT]
C. To regulate wages, overtime pay, and minimum wage standards for all industries
D. To provide workers compensation insurance for injured employees
Correct Answer: B
Rationale: The Occupational Safety and Health Act of 1970 established OSHA with the explicit mission to assure safe and healthful working
conditions for workers by setting and enforcing standards. Building codes and zoning fall under local authorities, wage regulations are governed
by the Fair Labor Standards Act (FLSA), and workers compensation is administered at the state level.
Q2: An OSHA compliance officer arrives at a construction site for an inspection. The site supervisor asks how
much advance notice OSHA is required to provide. What is the correct answer?
A. OSHA must provide 24 hours of advance notice for all inspections
B. OSHA must provide 48 hours of advance notice for construction sites only
C. OSHA must provide at least 1 week of written notice before any inspection
D. OSHA inspections are conducted without advance notice [CORRECT]
Correct Answer: D
Rationale: OSHA conducts inspections without advance notice to ensure that workplace conditions are observed in their normal state. Inspections
can be triggered by employee complaints, referrals, planned inspection schedules, or reported fatalities, and providing advance notice would
allow employers to temporarily conceal hazards that would otherwise be cited.
Q3: A construction worker believes that exposed electrical wiring on the jobsite poses a serious hazard. Under
OSHA regulations, which right does the worker have?
A. The right to shut down the entire jobsite immediately without employer consultation
B. The right to request an OSHA inspection and be free from retaliation for exercising safety rights
[CORRECT]
C. The right to personally issue citations to the electrical subcontractor
D. The right to refuse to work only if the hazard has been previously cited by OSHA
Correct Answer: B
Rationale: OSHA grants workers the right to a safe workplace, the right to information about hazards, the right to request an OSHA inspection,
and protection from retaliation for exercising these rights. Workers cannot unilaterally shut down a site or issue citations, as only OSHA
compliance officers have citation authority under the law.
Q4: A construction company was cited by OSHA for multiple safety violations. Which of the following is a
consequence the employer can expect?
A. Only a written warning on the first offense, with no financial penalties
B. Mandatory safety training for employees but no fines or penalties
C. Fines and penalties that vary based on the severity and type of violation [CORRECT]
D. Automatic closure of the jobsite for a minimum of 30 days
Correct Answer: C
Rationale: Employers who violate OSHA standards face fines and penalties that range from other-than-serious to willful or repeated violations,
each carrying different monetary amounts. Penalties can be substantial for willful violations and increase further for repeated offenses, but
automatic site closure is not a standard OSHA penalty.
Q5: Which of the following is an employer responsibility under OSHA?
NCCER Module 1 Safety Exam 2026-2027 Page 1
, A. Provide a workplace free from recognized hazards and comply with OSHA standards [CORRECT]
B. Allow workers to opt out of safety training if they have prior experience
C. Post the OSHA poster only if the company has more than 50 employees
D. Provide PPE only if the employee requests it in writing
Correct Answer: A
Rationale: OSHA requires employers to provide a workplace free from recognized hazards, comply with all applicable standards, provide PPE
at no cost to employees, maintain OSHA 300 logs, and post the OSHA poster regardless of company size. Employers cannot allow workers to opt
out of required training or condition PPE provision on employee requests.
Q6: A worker on a commercial construction project suffers a fatal injury on a Tuesday afternoon. By when
must the employer report this fatality to OSHA?
A. Within 24 hours of the incident
B. Within 8 hours of the incident [CORRECT]
C. Within 72 hours of the incident
D. Within 30 calendar days of the incident
Correct Answer: B
Rationale: OSHA requires employers to report fatalities within 8 hours and inpatient hospitalizations, amputations, or loss of an eye within 24
hours. The 8-hour fatality reporting requirement is one of the most critical employer obligations, and failure to report can result in additional
citations and monetary penalties.
Q7: Which OSHA form is the Log of Work-Related Injuries and Illnesses that employers must maintain?
A. OSHA 300A Summary
B. OSHA 301 Incident Report
C. OSHA 300 Log [CORRECT]
D. OSHA 200 Log
Correct Answer: C
Rationale: The OSHA 300 Log is the primary recordkeeping form for tracking work-related injuries and illnesses throughout the year. The
OSHA 300A is the annual summary posted from February 1 through April 30, and the OSHA 301 is the individual incident report form. The
OSHA 200 is an outdated form that was replaced by the current 300 Log system.
Q8: Under the Hazard Communication Standard (HCS), what must employers provide to employees regarding
hazardous chemicals?
A. Employers must provide Safety Data Sheets (SDS) and proper chemical labeling, and employees have the
right to know about hazardous chemicals [CORRECT]
B. Employers only need to provide verbal warnings about chemicals, with no written documentation required
C. Employers are only required to provide SDS for chemicals that are flammable
D. Employers must provide SDS only upon request from the employee
Correct Answer: A
Rationale: The Hazard Communication Standard (HCS) gives employees the right to know about hazardous chemicals in their workplace and
requires employers to provide Safety Data Sheets (SDS) and proper labeling for all hazardous chemicals present. This right-to-know standard
applies to all hazardous chemicals, not just flammable ones, and SDS must be readily accessible at all times.
Q9: A worker suffers an inpatient hospitalization after a scaffolding collapse on Monday morning. What is the
employer reporting obligation to OSHA?
A. No reporting is required since it was not a fatality
B. Report within 24 hours of learning about the hospitalization [CORRECT]
C. Report within 8 hours of the incident, the same as a fatality
D. Report only if the hospitalization lasts more than 48 hours
Correct Answer: B
Rationale: OSHA requires employers to report inpatient hospitalizations within 24 hours of learning about the incident. The 8-hour reporting
window applies only to fatalities, while the 24-hour window covers inpatient hospitalizations, amputations, and loss of an eye. This distinction is
a commonly tested difference on NCCER safety exams.
Q10: When must the OSHA 300A Summary be posted by the employer?
A. From January 1 through March 31 of each year
