Intervention is defined as specific services, activities or products developed and implemented to change or improve individuals’ risk, attitudes, behavior, and awareness.  Intervention is a purposeful response to an event or possible event base on risk assessment.  The intervention can be direct, where services are provided at the scene of the exposure (the job) or the intervention can be provided indirectly to the individual (employee) by education and conditioning.  Interventions can take many forms and involve the action of a variety of professionals.

Workplace interventions may include modifications to methods, materials, and processes.
