STATISTIK KECELAKAAN - Frequency Rate (FR) dan Severity Rate (SR)

Summary

In this video, the speaker discusses how to calculate key safety metrics, such as frequency rate (FR) and severity rate (SR), based on workplace accidents in the mining industry. The video references Indonesian regulations, specifically Kepmen 185/2019, which standardizes lost workdays for different injuries. The speaker clarifies common misunderstandings regarding the measurement units (days vs. hours) and emphasizes the importance of accurate reporting for assessing safety performance. The video also touches on how these metrics serve as indicators of effective safety management in mining operations.

Takeaways

• 🛠️ The script focuses on mining industry safety, addressing the calculation of lost workdays due to accidents.
• 📜 The discussion is based on regulations from the Dirjen Minerba, specifically Nomor 185 Tahun 2019, which provides a standard for calculating lost workdays in mining.
• 👷‍♂️ Amputation injuries, such as losing the tip of a thumb, result in 300 lost workdays, as specified in the mentioned regulation.
• ⏱️ The calculation for lost time is based on workdays, not work hours, despite some confusion in safety groups.
• 📊 Two key safety indicators are used: Frequency Rate (FR) and Severity Rate (SR), which are essential in evaluating workplace safety management.
• 🔢 FR is calculated by dividing the number of accidents by cumulative work hours, multiplied by one million.
• 💼 The script emphasizes that high FR and SR numbers indicate poor safety performance, even if safety programs exist.
• ⚠️ FR doesn’t differentiate between minor and severe injuries, so SR is used to reflect the severity of incidents by counting lost workdays.
• 📝 SR is calculated by dividing the total lost workdays by cumulative work hours, multiplied by one million, emphasizing the difference between FR and SR.
• 🔍 In conclusion, the presenter reinforces that the unit for measuring lost time is in days, not hours, as per the regulation and industry standard.

Q & A

What is the main topic discussed in the transcript?

The transcript discusses the calculation of lost workdays and accident statistics, particularly in the mining industry, using specific formulas and guidelines from Indonesian regulations, such as Kep Dirjen Minerba 185/2019.

What is the importance of determining workdays lost in accident reports?

Determining workdays lost is crucial because it helps measure the severity of workplace accidents. It reflects how long injured workers are unable to return to their normal duties and provides a key metric in safety performance evaluations.

What confusion is addressed in the video regarding lost workdays?

The confusion addressed is whether the lost time from accidents should be measured in days or hours. The video clarifies that in the guidelines of Kep Dirjen Minerba 185/2019, the unit of lost workdays is measured in days, not hours.

How does the video explain the calculation of 'Frequency Rate' (FR) in accident statistics?

The Frequency Rate (FR) is calculated by dividing the number of accident victims by the total cumulative work hours, then multiplying the result by one million. This calculation is used to standardize accident frequency over a year.

What is 'Severity Rate' (SR), and how is it calculated?

The Severity Rate (SR) represents the seriousness of workplace accidents by calculating the total number of lost workdays due to injury. It is computed by dividing the total lost workdays by the cumulative work hours and then multiplying by one million.

Why is it important to differentiate between minor and severe injuries in accident reports?

It’s important because Frequency Rate (FR) alone does not distinguish between the severity of accidents. For instance, a company with many minor injuries might have a higher FR than a company with fewer, but fatal, injuries. Severity Rate (SR) helps account for the seriousness of the injuries.

Why is a standard table of lost workdays used in calculating SR?

A standard table of lost workdays, such as the one in Kep Dirjen Minerba 185/2019, is used to ensure consistency in reporting the number of lost days for specific injuries. It standardizes how different injuries, like amputations, are recorded across different workplaces.

What assumptions are made when calculating the one million work hours in the formula?

The one million work hours assume an average workforce of 500 people, each working 8 hours per day, with 250 workdays in a year. This calculation is used as a standard constant for annual accident reporting.

How are partial workdays treated in accident statistics according to the transcript?

Partial workdays are still counted as lost days if the injured worker cannot return to their regular duties. For example, if a worker comes back but performs a different task due to injury, those days are still considered lost until they resume their original duties.

What is the significance of FR and SR in evaluating safety management performance?

FR and SR are key indicators of the success of safety management. A low FR and SR suggest fewer and less severe accidents, respectively, while higher numbers indicate potential issues in implementing safety protocols effectively.
