Hazard Process Properties

A hazard object has a processing cycle that consists of stages for Analysis, Evaluation, Reduction, Verification, and Completeness. This topic describes the fields in each process.

This page discusses:

Analysis
Evaluation
Reduction
Verification
Completion

Analysis

In the Analysis process you enter basic hazard details.

Analysis Fields


Field Name	Description
Current Severity	The current severity level. Values are 1 through 5.
Initial Severity	The initial severity level.
Current Occurrence	The current occurrence level. Values are 1 through 5.
Initial Occurrence	The initial occurrence level.
Current RPN	The current Risk Priority Number for the hazard. The system calculates the RPN value by multiplying the probability value by the impact value. The probability and impact 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).
Initial RPN	The initial Risk Priority Number for the hazard.
Title	The title of the hazard.
Process	The current process of the hazard.
Identification	Whether the hazard is "Known," "Foreseeable," or "Undefined."
Sequence of Events	The sequence of events for hazardous situations.
Condition	Whether the hazard is possible in a "Normal" or "Fault" condition. This can also be "Undefined."
Hazardous Situation	Circumstances in which people, property or environment are exposed to hazards.
Major Classification	The major classification of the hazard.
Harm	Identifies physical injury or damage to people, damage to property or environment.
Minor Classification	The minor classification of the hazard.

Analysis Actions/Toolbar Commands


Action	Description	For More Information
Done	Saves the entered information and keeps the hazard object in the Analysis process.	--
Start Risk Evaluation	Completes the Analysis process and moves the hazard object to the Evaluation process.	Evaluation
Restart Risk Analysis	Displays only when a hazard has completed the Analysis process. Moves the hazard back to the Analysis process.	--

Evaluation

In the Evaluation process, you determine how acceptable the risk is.

Evaluation Fields


Field Name	Description
Risk Acceptability Criteria	The criteria that should be met to accept the risk on this hazard.
Risk Acceptable	Whether the risk is acceptable, or undefined.
Risk Reduction Required	Whether risk reduction is required to make the risk aceptable.
Risk Acceptable Justification	The justification for accepting the risk.
Risk Reduction Not Required Rationale	The reason why risk reduction is not required.

Evaluation Actions/Toolbar Commands


Action	Description	For More Information
Done	Saves the entered information.	--
Start Risk Reduction	Displays if "Risk Reduction Required" is set to "Yes." Completes the Analysis process and moves the hazard object to the Reduction process.	Reduction
Restart Risk Evaluation	Displays only when a hazard has completed the Evaluation process. Moves the hazard back to the Evaluation process.	--

Reduction

In the Reduction process, you adopt/apply one or more risk reduction options.

Reduction Fields

To edit reduction options, see Hazard Reduction Options.


Field Name	Description
Option	The risk reduction option. Typically, this is an option to ensure safety or provide a protective measure.
Measure	The control measure taken. A free-text area.
Implementation Practicable	Whether the control measure can be put into practice successfully.
Implementation Verification	Verification of control measure implementation.
Effectiveness Verification	Verification of the control measure's effectiveness.
Residual Risk	The risk remaining after the control measure is taken.
Residual Risk Disclosure Information	Safety information to be disclosed for a residual risk.
Residual Risk Disclosure Verification	Verification of the residual risk disclosure.
Generates Hazard	Whether the mitigation of the current hazard generates any new hazards.

Reduction Actions/Toolbar Commands


Action	Description	For More Information
Mass Update	Updates values in the column name you select with the value you enter. You can apply an update to all options or only to selected options.	--
Save	Saves any information you entered or updated.	--
Complete Risk Reduction	Completes the Risk Reduction process and moves the hazard object to the Verification process.	Verification
Restart Risk Reduction	Displays only when a hazard has completed the Reduction process. Moves the hazard back to the Reduction process.	--

Verification

In the Verification process, you verify the risk reductions.

Verification Fields

The table is the same as the one used in the Reduction process. See Reduction. You are allowed to update verification fields if you restart the verification process.

Verification Actions/Toolbar Commands


Action	Description	For More Information
Restart Risk Reduction Verification	Displays only when a hazard has completed Verification process. Allows you to update verification fields.	--
Complete Risk Reduction Verification	Completes the verification process and moves the hazard object to Completion.	Completion

Completion

In the Completion process, you make any updates to the hazard based on previous risk processing.

Completion Fields


Field Name	Description
Current Severity	The current severity level. Values are 1 through 5.
Initial Severity	The initial severity level.
Current Occurrence	The current occurrence level. Values are 1 through 5.
Initial Occurrence	The initial occurrence level.
Current RPN	The current Risk Priority Number for the hazard. The system calculates the RPN value by multiplying the probability value by the impact value. The probability and impact 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).
Initial RPN	The initial Risk Priority Number for the hazard.
Residual Risk Acceptable	Whether the residual risk is acceptable.
Risk/Benefit Analysis	A free-form field for any risk/benefit analysis.
Disclose Residual Risk	Whether to disclose the residual risk.
Benefit Exceeds Risk	Whether the benefit exceeds the risk.

Completion Actions/Toolbar Commands


Action	Description	For More Information
Done	Saves any information you entered or updated.	--
Complete Review	Completes all hazard processing. After the review is completed it is possible to restart one of the earlier processes and make updates to risk information..	--
