How are OEH hazards generally characterized?

OEH hazards are characterized as any chemical, biological, or physical health hazard because this classification encompasses a wide range of potential threats to human health and the environment. Understanding OEH hazards in this broad manner allows for a comprehensive approach to risk assessment and mitigation. This includes recognizing various types of hazards, from toxic substances and infectious agents to physical agents like radiation or noise, which can all have detrimental effects on health.

By including all three categories – chemical, biological, and physical – the assessment of OEH hazards becomes more effective and inclusive, ensuring that various sources of risk are acknowledged and managed appropriately. This holistic perspective is crucial in bioenvironmental engineering and public health to devise effective solutions and protective measures against diverse environmental hazards. The other options are too limited in scope, focusing only on specific aspects of hazards rather than the comprehensive view necessary for effective assessment and intervention.
