Hazards

This page shows the hazards associated with products.

You can relate hazard objects to requirements in the Traceability Matrix tab.

To access this page:

  1. From the Design Projects tab, click a design project name.
  2. In the navigation pane for the design project, click Traceability.
  3. Click the Hazards tab.

Columns

Column NameDescription

Name

If the context is a design project, a tree structure displays the root node of the product, expanded to the hazards, which can be further expanded to related hazards.

If the context is a product, no root product object is shown since the context is already that of the product. Hazards are directly listed, which can be further expanded to related hazards.

TypeThe object type, which is "Hazard."
StateThe lifecycle state of the hazard object.
RequirementsThe number of requirements for the hazard.
TitleThe hazard title.

Identification

Whether the hazard is "Known" or "Foreseeable."
ConditionWhether the hazard is possible in a "Normal" or "Fault" condition.
MajorThe major classification of the hazard.
MinorThe minor classification of the hazard.
Sequence of EventsThe sequence of events for hazardous situations. A rich-text enabled field.
Hazardous Situation Circumstances in which people, property or environment are exposed to hazards.
Harm Identifies physical injury or damage to people, damage to property or environment.
Parent HazardsThe name of the parent hazards to which this hazard is associated as a related hazard.

Current SevCurrent severity of the hazard.
Current OccCurrent occurrence of the hazard.
Current RPNCurrent Risk Priority Number for the hazard. The system calculates the RPN value by multiplying the occurrence (probability) value by the severity (impact) value. The occurrence and severity values can both range from 1 to 5, 1 being the lowest and 5 the highest. Therefore, the RPN can range from 1 (1x1) to 25 (5x5).
Original SevOriginal severity of the hazard.
Original OccOriginal occurrence of the hazard.
Original RPNOriginal Risk Priority Number for the hazard. The system calculates the RPN value by multiplying the occurrence (probability) value by the severity (impact) value. The occurrence and severity values can both range from 1 to 5, 1 being the lowest and 5 the highest. Therefore, the RPN can range from 1 (1x1) to 25 (5x5).
AcceptableIndicates whether the residual risk is acceptable.
Benefit Exceeds RiskIndicates whether the benefit exceeds the risk.
DisclosureThe residual risk disclosure.
OwnerThe owner of the hazard.

Traceability Context Actions/Toolbar Commands

ActionDescriptionFor More Information
Relate RequirementTo execute this command, select one or more requirement or document objects in the Design Input table in the Traceability Matrix tab. Then select one or more objects in the Hazards table. This command associates the selected documents and requirements to the selected hazard objects.

This action opens a form where you can optionally type the "Reference within the selected document." Once submitted, the provided text is set in the attribute on the "Mitigated By" relationship.

The Traceability Matrix is refreshed to show the updated details.
