Program Objectives In light of industrialization trends across the globe, new hazards are constantly introduced in many workplaces. This program aims to provide Young Safety Professionals (YSPs) from diverse backgrounds with the requisite skill to address the health and safety hazards in the modern workplace.

5. The Risk Assessment Process
Hazard Analysis & Risk Assessment Process from ANSI/ASSE Z590.3-2011
1) Data gathering –
Injury and protective data
2) Set scope or Limits of Assessment
3) Develop and charter risk reduction team
4) Identify task and hazards
5) Assess risk – Initial risk scoring system
6) Reduce risk – Hazard control hierarchy
7) Assess Risk – residual risk scoring system
Identify current
controls
Test/verify

6. The Risk Assessment Process
 The purpose of the risk assessment matrix is to provide “a method to
categorize combinations of probability of occurrence and severity of harm,
thus establishing risk levels.” (ANSI/ASSE Z590.3-2011)
 It is important that the risk rating criteria and matrix used by an organization
are consistent.
 When developing or selecting a risk assessment matrix which expresses
numerical values, rating criteria should be standardized so that a lower risk
score or risk priority number (RPN) value indicates a lower risk level.
 Thus, on a 10 point risk scale, a risk score of 1 is considered the lowest level, while a 10
is considered the highest risk.

10. The Risk Assessment Process
Establish Context
1. Define the purpose and scope of the risk assessment.
2. Set the boundaries for the assessment with internal (resources, knowledge,
culture and values among others) and external (legal, regulatory, economy,
perceptions of external stakeholders, etc.) parameters in mind.
3. Should be clear, concise and well understood by all stakeholders.
4. Clearly define and communicate the risk criteria and ‘acceptable risk’ level.

11. The Risk Assessment Process
Assemble Team
1. Context of the risk assessment assignment will determine the size and makeup
of the team.
2. Cross-functional group of individuals who are familiar and knowledgeable with
the hazards and operations.
3. May require outside expertise in more complex situations.
4. Good communication and skills are essential.

12. The Risk Assessment Process
Identify Hazards
and Risks
 Hazards are the source of risk. Thus, if risks are to be assessed, hazards must
first be identified.
 Risk identification is defined as the process of finding, recognizing and
recording risks
 Key components of risk identification are the identification of the causes and
source of the risk (hazard in the context of physical harm), events, situations or
circumstances which could have a material impact upon objectives and the
nature of that impact. Once identified, existing controls for the risk should also
be identified. (ANSI Z690.3-2011)

13. The Risk Assessment Process
Analyze Risks
 Risk analysis involves developing an ‘understanding’ of the risk. (ISO
31010/ANSI Z690.3)
 The analysis of each hazard/risk includes:
 determining the severity of consequences
 estimating the likelihood of occurrence
 assessment of the effectiveness of existing controls
 an estimation of the risk level

14. The Risk Assessment Process
Evaluate Risks
 Risk evaluation involves comparing the estimated risk levels with the defined risk
criteria to determine the significance of the level and type of risk.
 It is based on the combination of estimated consequences and likelihood and
uses information from the hazard/risk identification and risk analysis phases to
make recommendations for decision makers.

15. The Risk Assessment Process
Treat Risks
 Risks that are judged unacceptable must be ‘treated’ to reduce risk.
 The risk treatment process involves:
 the assessment of a risk treatment;
 determining if residual risk levels are tolerable;
 selecting new risk treatments for those residual risks that are not
acceptable;
 and assessing the effectiveness of any new control measure.
 Risk treatment involves the selection and implementation of one or more risk
control measures or enhancements to existing controls. Treatment options
include:
1. avoiding the risk by deciding not to start or continue with the activity
that gives rise to the risk;
2. removing the risk source;
3. changing the likelihood;
4. changing the consequences;
5. sharing the risk with another party such as insurance contracts and
risk financing; and
6. retaining the risk by informed decision.

16. The Risk Assessment Process
Document
 Successful risk assessment processes are dependent on effective communication
among stakeholders prior to, during and after the process.
 Virtually all aspects of the risk assessment process should be documented
 Selecting the risk assessment matrix
 Determining the purpose and scope (context)
 Selecting the team
 Identifying the hazards or operations to be assessed
 Hazard/risk identification
 Risk analysis
 Risk evaluation
 Communication and documentation
 Monitoring and continuous improvement

17. The Risk Assessment Process
Monitor and Review
 Hazards and operations continuously change and with these changes come new
and different risks.
 Examples of these might include different equipment, processes, operating
environments, production rates, etc. Each of these changes could have an effect
on the existing controls and their effectiveness.
 Thus, it may be appropriate to update risk assessments to consider these
possible changes.
