Probabilistic Approach for Assessing the Occupational Risk of Olfactometric Examiners: Methodology Description and...

Area of Science:

• Occupational Health and Safety
• Environmental Science
• Toxicology

Background:

• Human examiners (panelists) face unknown occupational risks during dynamic olfactometry.
• Existing occupational risk assessments for olfactometry are primarily deterministic.
• A need exists for a more robust risk assessment methodology in olfactometry.

Purpose of the Study:

• To develop and apply a probabilistic risk assessment approach for olfactometric examiners.
• To evaluate occupational exposure risks using randomized exposure parameters.
• To compare probabilistic risk assessment with deterministic methods.

Main Methods:

• Utilized a Monte Carlo simulation to randomize exposure parameters.
• Conducted a one-year survey of olfactometric examiners' working activities.
• Calculated hazard index (HI) and inhalation risk (IR) for non-carcinogenic and carcinogenic risks.

Main Results:

• Developed probability distributions for risk parameters based on collected data.
• Compared risk distributions across different industrial sample categories.
• Determined negligible non-carcinogenic and carcinogenic risks for panelists based on annual data.

Conclusions:

• Probabilistic risk assessment offers a comprehensive evaluation of olfactometric examiner exposure.
• This approach surpasses the limitations of deterministic methods.
• The methodology can inform effective risk management strategies for protecting examiner health.
