General Contractor License Safety and OSHA Regulations Questions and Answers — Questions and Answers
Question 1: According to OSHA standards for construction (29 CFR 1926), what is the minimum height at which fall protection is required on a walking/working surface with an unprotected side or edge?
- 4 feet
- 10 feet
- 6 feet (Correct answer)
- 8 feet
Correct answer: 6 feet
OSHA standard 29 CFR 1926.501(b)(1) requires that employees on a walking/working surface with an unprotected side or edge that is 6 feet or more above a lower level must be protected from falling by a guardrail system, safety net system, or personal fall arrest system.
Question 2: A trench is dug to a depth of 8 feet in Type B soil. Which of the following is an acceptable protective system according to OSHA?
- Benching the excavation walls at a 90-degree angle.
- Having a competent person visually monitor the trench for signs of collapse while work is performed.
- Sloping the excavation walls at a 1-to-1 ratio (45 degrees). (Correct answer)
- No system is needed as long as the trench is less than 10 feet deep.
Correct answer: Sloping the excavation walls at a 1-to-1 ratio (45 degrees).
For trenches deeper than 5 feet, a protective system is required. For Type B soil, OSHA allows for sloping at a maximum angle of 45 degrees (a 1-to-1 horizontal to vertical ratio). Benching at 90 degrees is never acceptable, and visual monitoring alone is not a substitute for a required protective system.
Question 3: Under OSHA's Hazard Communication Standard (HCS), which of the following is a key responsibility of a general contractor on a multi-employer worksite?
- Authoring the Safety Data Sheet (SDS) for every chemical brought on site.
- Ensuring Safety Data Sheets for all hazardous chemicals are readily accessible to all workers. (Correct answer)
- Personally testing each chemical to verify its listed hazards.
- Requiring subcontractors to use only non-hazardous materials.
Correct answer: Ensuring Safety Data Sheets for all hazardous chemicals are readily accessible to all workers.
The Hazard Communication Standard requires employers to have a written program and ensure that all workers, including those of subcontractors, have access to information about the hazardous chemicals they may be exposed to. This is primarily achieved by maintaining an inventory and ensuring Safety Data Sheets (SDSs) are available. The manufacturer or importer authors the SDS, not the contractor.
Question 4: A worker is tasked with servicing a permanently installed air conditioning unit. To comply with Lockout/Tagout (LOTO) standards, what is the critical first step in the process?
- Apply the lock and tag to the disconnect switch.
- Immediately begin the repair to minimize downtime.
- Verify that the system is de-energized by trying to start it.
- Notify all affected employees that the equipment will be shut down for service. (Correct answer)
Correct answer: Notify all affected employees that the equipment will be shut down for service.
The first step in the LOTO procedure is preparation, which includes identifying all energy sources and notifying all affected employees of the impending shutdown. This ensures that no one attempts to operate the equipment while it is being serviced. Applying the lock, verifying isolation, and performing the work all come after notification and shutdown.
Question 5: A contractor identifies a serious ergonomic hazard related to repetitive heavy lifting that is causing injuries, but there is no specific OSHA standard for this particular task. Under which provision can OSHA still cite the employer for failing to protect its workers?
- The Whistleblower Protection Act
- The General Duty Clause (Section 5(a)(1)) (Correct answer)
- The Personal Protective Equipment (PPE) Standard
- The Hazard Communication Standard (HCS)
Correct answer: The General Duty Clause (Section 5(a)(1))
The General Duty Clause, Section 5(a)(1) of the OSH Act, requires employers to provide a workplace free from recognized hazards that are causing or are likely to cause death or serious physical harm. It is used to cite employers for hazards when no specific standard applies, such as ergonomics or workplace violence.
Question 6: An employer is required to maintain records of work-related injuries and illnesses. Which OSHA form serves as the detailed incident report for each individual recordable case?
- Form 300A (Summary of Work-Related Injuries and Illnesses)
- Form I-9 (Employment Eligibility Verification)
- Form 300 (Log of Work-Related Injuries and Illnesses)
- Form 301 (Injury and Illness Incident Report) (Correct answer)
Correct answer: Form 301 (Injury and Illness Incident Report)
OSHA's recordkeeping system uses three forms. Form 301 is the Injury and Illness Incident Report, which is used to capture detailed information about each specific incident. Form 300 is the log where all incidents are tracked throughout the year, and Form 300A is the annual summary that gets posted for employees to see.
