Figure 1 — Graphical Representation for Business Object Hazard

Hazard

This information object represents information about an identified hazard arising as a result of normal operation of an item.

NOTE This includes all aspects of operation of the system, including operational use, maintenance, installation, decommissioning etc. as well as the potential impact on indirect uses and users, such as the effect on bystanders. It also includes different states of system operation and the conditions which emerge as a result of those different states.

Defined_for	This is the reference to the usage context of the item, or a task, for which the hazard is defined.	SELECT of Task, Product Role, or Required PSE Constituent Usage Pattern	Mandatory
Description	This is the description of the hazard.	intrinsic	Optional
ID	This is the identifier of the hazard.	Relationship to Identifier	Mandatory
Name	This is the name of the hazard.	intrinsic	Optional
Quantity	This is the quantification of the hazard category that has been identified as being caused by the source.	Intrinsic	Optional

Related Support Solution	This is a reference to the related support solution.	Relationship to Support Solution Definition	Mandatory
Severity	This is the severity category of the hazard.	Intrinsic	Mandatory

The instance diagram in Figure 4 shows an example of the EXPRESS entities and templates that are instantiated by the template:

/hazard(Category='Hazard_category', Defined_for='@158', Description='Description of hazard', ID='H001', ID_source_organization='UK_Defence', Name='Name of hazard', Name_source_organization='UK_Defence', Quantity_value='50', Quantity_unit='Percent', Related_support_concept='@305', Related_support_solution='@385', Severity='Severity_category', Source='@104')/

(an illustration of the consolidated hazard template is shown in Figure 5 below.)

The instance diagram in Figure 5 shows the graphic symbol for the template that is to be used in other instance diagrams. The example template is:
