Free OHST Exam Questions That Helps Candidates Pass

Comprehensive and Detailed Explanation:

750 ÷ 15 = 50 units per hour

So the correct answer is B.

OHST professionals use production rate analysis to evaluate workload intensity and identify potential safety risks such as fatigue or equipment stress.

Comprehensive and Detailed Explanation:

Payback period is calculated as:

Cost ÷ Annual savings = 18,000 ÷ 6,000 = 3 years

So, the correct answer is B.

In OHST practice, payback period analysis helps justify safety investments such as engineering controls, training programs, and protective equipment. It demonstrates how long it takes for a safety improvement to recover its cost through reduced injuries, downtime, and compensation expenses. Safety professionals use this data to support management decisions and prioritize risk reduction projects.

Comprehensive and Detailed Explanation:

The correct answer is B.

Ethical responsibility requires timely and honest reporting of hazards to prevent harm. Safety professionals must ensure accurate communication of risks.

Ethical conduct strengthens safety systems and organizational trust.

Comprehensive and Detailed Explanation:

Percentage reduction is calculated as:

[

\frac{240 - 180}{240} \times 100 = \frac{60}{240} \times 100 = 25%

]

So, the correct answer is B.

In OHST practice, tracking lost work hours helps measure the impact of injuries on productivity and operational efficiency. A reduction indicates improved safety performance, better hazard control, or more effective return-to-work programs. Safety professionals use this metric to evaluate the effectiveness of interventions such as training, engineering controls, and enforcement of safe work procedures.

Comprehensive and Detailed Explanation:

The correct answer is B.

Ethical safety practice requires honesty, accountability, and timely reporting of hazards. Reporting unsafe conditions ensures that risks can be addressed before incidents occur.

OHST professionals are responsible for protecting workers by identifying and communicating hazards clearly and accurately. Ethical behavior strengthens trust and supports effective safety management systems.

Failure to report hazards can lead to preventable injuries and undermines organizational safety efforts.
