Input parameters

The following input parameters are defined for this template:

Description (Type='STRING')

The description of how the risk may arise as a result of the hazard.

ID (Type='STRING')

The identifier of the hazard risk relationship.

ID_source_organization (Type='STRING')

The organization that created the identifier.

Related_hazard (Type= 'ENTITY (Activity_actual)' )

The reference to the hazard that may result in the associated risk.

Risk_arising (Type= 'ENTITY (

Error ER1: The entity Risk does not exist
Risk)'

Error EXP-1: The EXPRESS entity Risk
does not exist in data/schemas/ap239_arm_lf.xml.
)

The reference to the risk that may arise as a result of the related hazard.

Reference parameters

The following reference parameters are defined for this template:

hazard_risk_relationship(Type='ENTITY (Applied_activity_assignment)')

Allow the Applied_activity_assignment entity instantiated in this path to be referenced when this template is used.

Note: The Applied_activity_assignment entity can be referenced in a template path by:

%^target = $hazard_risk_relationship.hazard_risk_relationship%

where target is the parameter to which the Applied_activity_assignment is bound.

Instantiation path

The instantiation path shown below specifies the entities that are to be instantiated by the template.

A description of templates and the syntax for the instantiation path is provided in the Templates Help/Information section.
