Evaluate the risk and decide on precautions
Table 1 outlines the consequence levels by assigning numerical values to each level, providing clear definitions regarding their impacts on the environment, health and safety, production loss, and property damage In cases of uncertainty about which outcome poses a greater risk, both outcomes should be evaluated, and the one with the higher risk level should be chosen.
Where there is doubt as to which outcome would have the highest risk level, both should be considered with the highest one being selected
Negligible impact on strategic objectives Nil/negligible:
Injury, loss, service interruption, environmental/estate impact, impact on reputation impact on quality litigation or complaint
Small variance from overall strategic objective First aid treatment with full recovery
Complaint possible Local low key external interest
Minor: financial loss (up to 5K),service interruption
,environmental/estate impact, impact on reputation, impact on quality
Notable variance from overall strategic objective Medical treatment required up to 3 months to recover
Reportable under RIDDOR(Reporting of Injuries, Diseases and
A moderate financial loss ranging from $5,000 to $200,000 can lead to service interruptions exceeding one week, alongside potential environmental and estate impacts This situation may also affect the organization's reputation, drawing concern from local press and stakeholders While there is a moderate risk of losing valuable information, recovery is possible, resulting in a moderate loss of data and a low-value claim.
Significant variance from overall strategic objective Long term illness or injury (up to one year)
Reportable under RIDDOR Complaint expected/received
A major financial loss ranging from $200,000 to $3 million can occur due to service interruptions lasting over one month, which also lead to environmental and estate impacts that compromise service delivery Such disruptions significantly tarnish the organization's reputation, attract substantial media attention for over a week, and raise serious concerns among stakeholders Additionally, these issues adversely affect quality, increasing the risk of failing to meet established standards.
‘excellent’ in annual health check in one or more standards, major loss of information (recoverable) , high value claim or action by HSE anticipated, moderate risk of low value claim
Failure to meet strategic objective threatens independent functioning or stability
The potential consequences of a significant data breach include severe financial losses exceeding $3 million, reputational damage that could attract national media attention for over three days, and the risk of serious long-term or permanent loss of critical information affecting service delivery Additionally, external controls may be enforced, leading to threats of judicial review and anticipated litigation valued at over $1 million The breach could also involve high-profile exposure of confidential information, such as patient identities, and may result in the condemnation of buildings or property, causing substantial disruption to services.
Likelihood can be examined with regard to the chance that a particular outcome will happen to any of the following:
• A single person or member of the general public
• The project (more persons potentially exposed)
Table 2 – Likelihood Levels below assigns a number to the likelihood As can be seen, likelihood can be very variable In order to protect people on a Project, the Likelihood Level for
Scor e Descriptor LIKELIHOOD OF REPEAT EVENT
1 Very unlikely to occur Will only occur in exceptional circumstances
2 Unlikely to occur Unlikely to occur but the potential exists
3 Could occur Reasonable chance of occurring – has happened before on occasions
4 Likely to occur Likely to occur – strong possibility
5 Almost certain to occur The event is expected to occur in most circumstances
• Use the Risk Matrix Tool and guidance in the Risk Assessment pro forma to grade the risk
Negligib le Minor Moderate Major Catastroph ic / Fatal Consequence
A combination of Tables 1 and 2 can be used to evaluate the risk by determining the overall risk level of a particular outcome eventuating
The matrix (Table 3 - Risk Level Matrix) below is shown in the conventional format of
Consequence on the horizontal axis increasing to the right and Likelihood on the vertical axis increasing with height
Escalation of Risk is determined by risk score
Risk level Risk score Escalation level
Extreme Red 15- 25 Board of Directors
High Orange 9-12 Management committee (reporting to Board) Moderate Yellow 6-8 Directorate/Department
Department but monitored at Directorate level
• For an initial risk assessment, the Risk Level is known as the Risk Factor Number
• For a residual risk assessment, the Risk Level is known as the Residual Risk Number
• In both cases, the risk level dictates the response and timing of risk controls required
The management of risks identified through the risk assessment process will be determined by the risk rating
The amount of effort/resources that are to be committed to an identified risk is determined by the risk score The Contractor has a scheme of escalation
• Risks scored 1-5: are considered low risk (L) and therefore risks are accepted (tolerated) by the Contractor No more countermeasures are required.
