Intent

To provide a building block for modeling hazardous situations.

situations where one or more objects is exposed to one or morehazards to some extent (exposure value)

they have some cause that triggered the enactment of a hazard

they also result in some consequences

Competency questions

What object (person, organization, equipment etc.) is exposed to ahazard?

To which hazard is exposed an object (person, organization,equipment etc.)?

Which hazardous events are associated with a hazardous situation?

What is the cause of a hazardous event?

What is the consequence of a hazardous event?

What is the value of exposure of an object being exposed to a hazard?

Example scenario

”The farmer is spraying pesticides on the fields. He asked a studentworking on a farm for help in carrying pesticide sprayers and storagecontainers. In this situation, neither the farmer nor the student is wearingany personal protective equipment such as gloves or using any respirators.After 4 hours of spraying, they student developed skin irritation.”.

Example scenario: ODP population

Objects are Farmer and Student that are both Workers. The Workplace isthe field. HazardousSituation is associated with at least twoHazardousEvents both defined as a Worker (Farmer and Student) beingexposed to an OccupationalHazard (pesticides). The Cause of thisexposure is lack of personal protective equipment, and the immediateConsequence is HealthDeterioration (skin irritation).

Summary & future work

ODP for modeling hazardous situations and events

work done within modeling the domain of occupational safety andhealth

future work: adopting existing model(s) of events
