Those who are most at risk are: - people who have "unprotected sex" with someone who has HIV. - people who share needles, syringes or other equipment to inject drugs or medicine with someone who has HIV. - babies can potentially become infected during their mother's pregnancy, during delivery or after birth in the immediate post-partum period. they can also become infected through breastfeeding. - health care and maintenance providers who may be exposed to blood and body fluids.

Every day we conduct a rudimentary form of risk assessment without recognizing it as such.  When we consider the consequences of an action, so as to inform our decision on how to perform that action, we have carried out an assessment of the risk.  For example, when considering overtaking a vehicle, we assess if we can do it safely.

Within the workplace, risk assessments are critical for ensuring good occupational safety and health. The conduct of such assessments can significantly improve working conditions and therefore, contribute to increased productivity and efficiency.



What Really Is A Risk Assessment?

There are two components to risk assessment:


1. Risk Analysis


The process of scrutinizing a task or job to identify all of the associated hazards. During this phase the adequacy of precautionary measures is examined, and the risk involved is measured qualitatively or quantitatively.

2. Risk Evaluation  


The comparison of the measured risk against a pre-determined criterion to ascertain if the risk is tolerable.



How to Conduct A Risk Assessment

Step 1 - Establish the Objective


The reason for undertaking the risk assessment must be clearly understood, as should be the operation being assessed.  The objective may be to comply with legislation or simply improve occupational standards, thus the requirements of the legislation or standards must be known.

Step 2 - Define the  Activity


The set of tasks making up the job or process must be stated.  This lays the foundation for the next step.

Step 3 - Identify the Hazards


Examine every action so as to identify the potential hazards - those that may result from something going wrong, as well as those that may normally occur. A hazard is any physical, chemical or biological agent that has the potential to cause harm to individuals or damage to property.

Identifying hazards involves considering what; when; where; who; why; and how injury or damage can occur.
There are several techniques that may be used to assist in the identification of hazards such as: Hazard and Operability (HAZOP) Study; Failure Mode Effects Analysis (FMEA);  Fault-Tree Analysis (FTA) and Task-Based Analysis (TBA).

Step 4 - Analysing Consequences


Once it has been established that hazards exist, it is necessary to analyse the consequences should the hazards materialise.  This involves considering several factors including the number of persons affected; the severity and permanence of the injury.

Step 5 - Measuring the Risk


Risk refers to the likelihood or probability that a hazard will actually occur. In assessing the risk, consideration is given to the consequences. The risk may be measured or estimated in quantitative;  semi-quantitative or qualitative terms, using established models.  In measuring the risk, attention may be given to the adequacy of existing control measures. This is the final step in the risk analysis component and is the precursor to the risk evaluation aspect.

Step 6 - Evaluating the Risk


Having determined the degree of risk involved, the question is asked "Is the risk tolerable?" Recall that the primary objective should be to reduce the risk as low as is reasonably practicable (ALARP). With this in mind, the calculated risk is compared against  identified criteria which may be established occupational standards or industry standards.

Step 7 - Take Action


The need to take action will follow from the answer to Step 6.  If the risk is found to be tolerable, no action may be necessary but the process must be monitored and the risk assessment repeated at a later date or if any changes are introduced.  Where the risk is found to be unacceptable, appropriate corrective measures must be instituted.  Care must be taken to ensure that the action to be instituted does not create new hazards.

Step 8 - Monitor and Review


Maintaining acceptable occupational safety and health standards is a continuous process, thus monitoring and reviewing is crucial.  There may be instances when achieving acceptable standards must be done incrementally, thus repeating the risk assessment is essential.  Furthermore, conducting risk assessments at regular intervals demonstrates good enterprise governance  and commitment to safeguarding the well being of workers.



Who Should Conduct A Risk Assessment?


All health and safety initiatives should be the joint effort between employers and workers, and risk assessments are no exceptions.  Using the team approach increases the chances of success by allowing for the recognition of all hazards - without which the process will be flawed.



When Should A Risk Assessment Be Conducted?


The risk assessment process should be repeated until the risk is reduced to as low as is reasonably practicable. Risk assessment should be done on the introduction of a new process or after significant changes are made to an existing process. Risk assessment should also be periodically reviewed.
