Summary

This video presents a health risk analysis of toluene exposure among footwear factory workers in Ciomas, Bogor, West Java. The study assesses the hazard, exposure, and risk of non-carcinogenic effects of toluene. Workers' inhalation rates were calculated, and risk characterization using the Risk Quotient (RQ) determined that 5 out of 40 workers faced unsafe exposure levels (RQ > 1), while the rest were considered safe. The findings highlight the importance of monitoring and mitigating industrial chemical exposure to protect worker health.

Takeaways

• 😀 The script discusses a health risk analysis of toluene exposure among shoe factory workers in Ciomas, Bogor, West Java.
• 😀 The process starts with hazard identification, where toluene concentrations are measured at various points in the factory.
• 😀 Exposure assessment is performed by calculating the Individual Time-Weighted Average (intk) for each worker, using inhalation rate data.
• 😀 The study emphasizes that toluene exposure poses non-carcinogenic risks to workers, which is a key finding from the analysis.
• 😀 Dose-response values, such as the Reference Concentration (RFC), are derived from IRIS data and are crucial for assessing the potential health effects of exposure.
• 😀 The Risk Quotient (RQ) is used for risk characterization, comparing individual exposure values (intk) to the RFC values.
• 😀 If the RQ value exceeds 1, workers are categorized as being in the 'unsafe' exposure category.
• 😀 For this study, 5 workers had RQ values greater than 1, placing them in the unsafe category due to high exposure.
• 😀 35 workers had RQ values below 1, indicating their exposure levels were within the safe, acceptable range.
• 😀 The conclusion of the analysis helps to identify which workers need further intervention and protection to reduce health risks from toluene exposure.

Q & A

What is the purpose of calculating the Intake (intk) value in the health risk analysis?

The Intake (intk) value represents the amount of toluene inhaled by an individual worker, which is crucial for assessing their exposure and determining whether it exceeds safe levels.

How is the Risk Quotient (RQ) value calculated in this analysis?

The Risk Quotient (RQ) value is calculated by comparing the Intake (intk) value to the Reference Concentration (RFC) value. If the RQ is greater than 1, the exposure is considered unsafe.

What does an RQ value greater than 1 signify?

An RQ value greater than 1 indicates that the exposure level is unsafe, meaning that workers may be at risk of adverse health effects from toluene exposure.

What method was used to measure toluene concentration in the workplace?

Toluene concentration was measured at 9 different points in the work area, allowing for a comprehensive assessment of exposure across the factory.

How many workers were involved in this health risk analysis study?

The study involved 40 workers from three different footwear industries in Ciomas, Bogor, West Java.

What kind of health risk did the study focus on for toluene exposure?

The study focused on non-carcinogenic health risks from toluene exposure, assessing whether the exposure levels were safe or unsafe for the workers.

What does the Reference Concentration (RFC) value represent in the analysis?

The RFC value is a threshold representing a safe exposure level for a substance. It is used to assess whether the measured intake exceeds safe limits.

Why was the RQ value used instead of other risk characterization methods?

Since the study focuses on non-carcinogenic effects, the RQ value was used to compare the intake with the RFC, which is the standard for non-carcinogenic risk characterization.

How are workers categorized based on their RQ values?

Workers are categorized into two groups based on their RQ values: those with an RQ above 1 are considered to be in the unsafe exposure category, while those with an RQ below 1 are considered to be in the safe category.

What were the results of the risk assessment for the workers in the study?

Out of 40 workers, 5 had an RQ value above 1, indicating unsafe exposure levels, while 35 workers had an RQ below 1, meaning their exposure was within safe limits.
