1. What is the Number of Fatalities Formula?

The Number of Fatalities formula calculates the estimated number of fatalities based on the Fatal Accident Rate, number of employees, exposure time, and number of days. It provides a quantitative measure of risk assessment in occupational safety.

2. How Does the Calculator Work?

The calculator uses the Number of Fatalities formula:

\[ n = \frac{FAR \times nE \times t \times d}{10^8} \]

Where:

\( FAR \) — Fatal Accident Rate (fatalities per 10⁸ exposure hours)
\( nE \) — Number of Employees
\( t \) — Time per day in seconds
\( d \) — Number of Days

Explanation: The formula estimates the number of fatalities by considering the risk rate (FAR), workforce size, daily exposure time, and duration of exposure period.

3. Importance of Fatal Accident Rate Calculation

Details: Accurate fatality estimation is crucial for occupational safety planning, risk assessment, implementing safety measures, and compliance with health and safety regulations.

4. Using the Calculator

Tips: Enter Fatal Accident Rate, number of employees, time per day in seconds, and number of days. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is Fatal Accident Rate (FAR)?
A: FAR is a measure of individual risk expressed as the estimated number of fatalities per 10⁸ exposure hours in occupational settings.

Q2: How is exposure time typically measured?
A: Exposure time is usually measured in hours, but can be converted to seconds for calculation purposes (1 hour = 3600 seconds).

Q3: What industries use this calculation?
A: This calculation is commonly used in high-risk industries like construction, mining, manufacturing, and chemical processing for safety planning.

Q4: Are there limitations to this formula?
A: The formula provides an estimate based on historical data and assumes constant risk factors. Actual results may vary due to changing safety conditions.

Q5: How can organizations reduce the number of fatalities?
A: Through improved safety protocols, regular training, proper equipment maintenance, and implementing safety management systems.
