Occupational risk management of engineered nanoparticles

Area of Science:

• Occupational health and safety
• Nanotoxicology
• Industrial hygiene

Background:

• Engineered nanoparticles (ENPs) present widespread occupational exposure risks.
• Limited toxicological data necessitates a precautionary approach to ENP handling.
• Current and future workers may be at risk from uncontrolled occupational exposures.

Purpose of the Study:

• To review a conceptual framework for occupational risk management of ENPs.
• To describe an approach for controlling ENP exposures under uncertainty.
• To integrate primary and secondary control strategies for worker protection.

Main Methods:

• Review of existing occupational risk management principles.
• Application of the hierarchy of controls (elimination, substitution, engineering, administrative, PPE).
• Inclusion of health surveillance and medical monitoring as secondary measures.

Main Results:

• A comprehensive framework for managing occupational risks associated with ENPs is proposed.
• The framework addresses exposure routes and factors influencing ENP biological activity.
• Integration of traditional industrial hygiene with health surveillance provides a robust control strategy.

Conclusions:

• A proactive risk management framework is crucial for protecting workers from ENP hazards.
• Implementing the hierarchy of controls, supplemented by health monitoring, can mitigate occupational risks.
• Further research into ENP toxicology is needed to refine control strategies.
