How Many Questions Are on the OSHA 30 Final Exam?

The OSHA 30 final exam typically consists of 100 multiple-choice questions. However, the exact number of questions may vary slightly depending on the training provider or course format. For example, with Osha.com, the final exam consists of 20 questions.

The exam covers all the topics taught in the OSHA 30 training program and tests your knowledge of the information covered throughout the course. Participants are required to achieve a passing score to obtain an OSHA 30 certification, which is typically set at 70% or higher. 

Keep in mind, you only get three opportunities to pass the final exam. If you do not pass it after the third try, you will be locked out of the course and cannot complete your outreach training in an online setting. 

How Long Is the OSHA 30 Final Exam? 

The OSHA 30 final exam completion time depends on the number of questions on the exam and how well you studied and attended class. 

As mentioned earlier, participants are required to achieve a passing score to obtain an OSHA 30 certification, which is typically set at 70% or higher. 

It's important to manage your time effectively during the exam and pace yourself so that you have enough time to read and answer all the questions. 

Moreover, you have six months from your course enrollment date to complete the 30-hour OSHA Outreach Training. Once the six months pass, your account expires, and you will be required to purchase the course again.

OSHA 30 Answer Key 

1. D) 10 feet 

Explanation: OSHA requires that a minimum clearance distance of 10 feet be maintained between overhead power lines and any person or equipment unless specific engineering controls are put in place to protect workers.

2. B) 50 pounds

Explanation: OSHA recommends that the maximum allowable weight for manually lifting objects is 50 pounds. Anything heavier than that should be lifted using mechanical aids such as cranes, forklifts, or hoists.

3. B) Before each use

Explanation: Scaffolds should be inspected before each use to ensure that they are in safe working condition. 

4. C) Mold exposure

Explanation: Biological hazards in the workplace include exposure to mold, bacteria, viruses, and other microorganisms. 

5. C) 6 feet

Explanation: Fall protection is required on a construction site when working at a height of 6 feet or more.

6. C) Fall hazards

Explanation: Excavation work presents a risk of cave-ins, which can lead to falls and other injuries. Proper shoring and trenching techniques should be used to prevent cave-ins and other hazards associated with excavation work.

7. A) Isolation of equipment from its energy source

Explanation: The most effective way to control hazardous energy during maintenance or servicing of equipment is to isolate the equipment from its energy source through lockout/tagout procedures. 

8. A) To prevent workers from being exposed to hazardous energy

Explanation: Lockout/tagout procedures are used to prevent workers from being exposed to hazardous energy, such as electrical, hydraulic, or pneumatic energy while servicing or maintaining equipment. 

9. B) Ultraviolet (UV) radiation

Explanation: Non-ionizing radiation hazards include UV radiation, infrared radiation, and microwave radiation, among others. Ionizing radiation hazards include X-rays, gamma rays, and beta particles. 

10. B) 10 feet

Explanation: A forklift must maintain a minimum distance of 10 feet from an electrical power line.
