Free OHST Exam Questions That Helps Candidates Pass

Comprehensive and Detailed Explanation:

The correct answer is C.

Injury rate is a reactive metric because it measures incidents that have already occurred. It is used to evaluate past safety performance.

OHST professionals use both reactive and proactive metrics to get a complete picture of safety performance.

Comprehensive and Detailed Explanation:

The correct answer is C.

Ignoring safety violations is unethical because it puts workers at risk and undermines safety systems. OHST professionals are responsible for identifying and addressing hazards promptly.

Ethical behavior ensures trust, accountability, and effective safety management.

Comprehensive and Detailed Explanation:

900 ÷ 9 = 100 units per hour

So, the correct answer is C.

OHST professionals use production rates to assess workload intensity and potential safety risks such as fatigue or equipment overuse.

Comprehensive and Detailed Explanation:

To determine the amount remaining, subtract the amount transferred from the original quantity:

900 − 275 = 625 gallons

Therefore, the correct answer is C.

Basic arithmetic calculations are frequently required in occupational safety and health work. Safety technicians may calculate inventory levels, chemical usage rates, exposure durations, training attendance, incident statistics, and equipment capacities. Accurate calculations help ensure compliance with procedures and support informed decision-making.

For example, understanding remaining chemical quantities may affect emergency planning, environmental compliance, hazard communication, and storage requirements. Errors in calculations can lead to operational problems or safety concerns. Therefore, strong mathematical skills are an important competency for OHST professionals.

The ability to perform accurate calculations also supports trend analysis, budgeting, risk assessments, and performance measurement. Reliable data contributes to better management decisions and improved safety outcomes throughout an organization.

Comprehensive and Detailed Explanation:

The correct answer is C, Percentage of completed safety inspections.

Leading indicators measure activities intended to prevent incidents before they occur. Examples include safety inspections, training completion rates, hazard correction rates, safety observations, and participation in safety meetings. These indicators provide insight into the effectiveness of preventive efforts.

In contrast, fatalities, injury counts, and compensation costs are lagging indicators because they measure events that have already occurred. While lagging indicators remain important for evaluating outcomes, they do not provide early warning signs of potential problems.

OHST professionals often help organizations develop balanced performance measurement systems that include both leading and lagging indicators. Monitoring preventive activities allows management to identify weaknesses before injuries occur.

A strong safety management system emphasizes proactive measures. Leading indicators encourage continuous improvement and help organizations focus on activities that reduce risk rather than simply tracking incidents after they happen.
