Risk Assessment Reports

PURPOSE

A risk assessment acts as guidance for the requirements for the identification, assessment and management of Health and Safety Hazards and Risk Assessment and Management Risk Management Plans will be applicable to all CSA Fire & Safety SHE personnel, Risk Assessors and Site Management.

Types of Risk Assessments

Baseline Risk Assessment

The purpose of conducting a baseline HIRA is to establish a risk profile or set a risk profile. It is used to prioritise action programmes for issue-based risk assessments with Baseline Risk Assessments the major and significant risks are identified and prioritized. A baseline risk assessment focuses on the identification of risk that applies to the whole organisation or project. Baseline risk assessments – Methodology and risk matrix:

Step 1   IDENTIFY TASK
Step 2   IDENTIFY POTENTIAL HAZARD
Step 3   IDENTIFY UNDER WHICH CONDITIONS THE HAZARD WILL OCCUR
Step 4   IDENTIFY EXISTING CONTROLS
Step 5   EVALUATE CONSEQUENCES
Step 6   EVALUATE PROBABILITIES
Step 7   EVALUATE RISK

Important details to note on the above steps

Step 4   EVALUATE CONSEQUENCES

How serious is the identified risk, and the consequences thereof, to safety, health, environment or financial?

Consequence rating factors

CONSEQUENCES
 
Safety
Health
Environmental
Financial loss and damages
Probability
1NegligibleFirst aid, moderate, bruising, abrasionMinor health impact, no lost time, complete recovery.Limited short-term impact, resulting in immediate or no clean up.Less than R10 000Very low – Rare, very unlikely: Less than once a year.
2MinorLost time injury, medical referral, stitches, serious sprainsTemporary illness, with recovery after exposure ceases.Medium impact on environment, short term recovery, clean up.R10 000 – R50 000Low – Not likely to occur, but not impossible. Few times a year.
3ModerateFracture, amputation, second degree burnsPossible medium-term incapacity/illness, with likely recovery.Measurable/serious damage to flora/fauna, medium term recovery.R500 000 – R1MILModerate – Possible. Isolated incidents could happen. Few times a week.
4SeriousSingle fatality, permanent disability, Para/quadriplegic, third degree burns.Exposure resulting in permanent illness/long term incapacity, but not deathMajor impact on environment, long term recovery, damage claims, fines.R1MIL – R10MILHigh – likely, Possible of regular occurrences have occurred, few times a week.
5MajorMultiple fatalities, permanent disability.Exposure which could result in deaths, permanent/total incapacities.Catastrophic eco system/environmental damage/pollution, closure of plant, withdrawal of permits.More than R10milVery high – Most likely. Common regular occurrences, certain to occur. Continuously, every day.

Step 5   EVALUATE PROBABILITIES

Probability rating factors.

1. Very low – Rare, very unlikely: Less than once a year.
2. Low – Not likely to occur, but not impossible. Few times a year.
3. Moderate – Possible. Isolated incidents could happen. Few times a week.
4. High – likely, Possible of regular occurrences have occurred, few times a week.
5. Very high – Most likely. Common regular occurrences, certain to occur. Continuously, every day.

Step 6   EVALUATE RISK

RAW RISK = SEVERITY x PROBABILITY

Risk ratings

1 TO 8 = Tolerable – no actions required
9 TO 16 = Avoid Hazard – review and improve work requirements or control measures as soon as possible
17 TO 25 = Intolerable – immediate improvement to work requirements or to control measures required

The output of a baseline risk assessment

it is a risk profile or set of risk profiles; and
it is a clear description of the methodology, system, terminology etc. used in the scoping exercise, and what may be required for the improvement of the baseline HIRA in the future.

Examples of baseline risk assessments

Hygiene and Health Surveys (Noise, Lighting, Ventilation, Temperature Extremes)
Environmental Impact and Aspect Registers
Fire Risk Assessments

Issue base risk assessment

The purpose of conducting an issue-based HIRA is to assist in the development of action plans for the treatment of significant and other risks.

This type of risk assessment is normally focused on at operational activities, processes and systems-based functions. It focuses the identification of the risks within a certain task, process or activity.

Risk profiles from the baseline HIRA form the basis for establishing issue-based HIRA programmes.

Issue-based risk assessments: Methodology and Risk Matrix

Methodology

The methodology of the Issue-based risk assessments will correspond with the Baseline risk assessments.

Step 1   INDENTIFY TASK
Step 2   IDENTIFY POTENTIAL HAZARD
Step 3   IDENTIFY UNDER WHICH CONDITIONS THE HAZARD WILL OCCUR
Step 4   IDENTIFY EXISTING CONTROLS
Step 5   EVALUATE CONSEQUENCES
Step 6   EVALUATE PROBABILITIES
Step 7   EVALUATE RISK

The output of an issue-based risk assessment

The output of an issue-based HIRA is clear recommendations to management for further action in terms of Section 11(2) of the MHSA.

Examples of issues based risk assessments

A new machine is introduced at the site
A system of work or an operations is changed
After an accident or a ‘near-miss’ has occurred
new designs, layouts, equipment, or processes, etc
Task risk assessments
findings that come to the fore during continuous HIRA
requests from employees
a change in the risk profile
new knowledge and information becoming available on the level of risk to employees
Process hazard analysis
Environmental impact assessments
Major hazardous installations risk assessments
HAZOP (Hazard And Operability Study

Daily risk assessment

The purpose of conducting continuous HIRA is to:

identify hazards with the purpose of immediately treating
significant risks.
gather information to feed back to issue-based HIRA; and
gather information to feed back to baseline HIRA.

Continuous risk assessments are done prior to each task done. It is done by the team conducting the work on site. The whole team will partake and sign the risk assessment before commencing.

Output of a continuous risk assessment

A continuous risk assessment should be conducted on a continuous basis in the work environment. It is a powerful and important form of assessment and should take place continually, as an integral part of day-to-day management. In continuous HIRA, the emphasis is on day to day hazard awareness, through HIRA, and immediate risk treatment.

In developing hazard awareness, memory joggers such as inspection checklists, pre-use checklists, and critical part and paths checklists, can be produced from management controls that are a product of issue-based HIRA. Planned Task Observations could also be conducted on an ongoing basis.

It is performed at an operational level, where the system, process and activities are monitored on a continuous basis by the operational floor management and first line supervisors.

It must not be sophisticated and should mainly be conducted by first line supervisors.

Formal training in this regard is essential. The main emphasis is on “hazard awareness through hazard identification”.

Examples of continuous risk assessment

Hazardous activities need to undergo this type of risk assessment prior to the conducting of the activity and can include:

Inspections
Critical task observations
OHS audits
Work permits
Toolbox talks
Medical surveillance
Occupational hygiene measurements
Planned maintenance systems

Business risk analysis

The purpose of conducting a business risk analysis is to identify and mitigate the impact and financial loss of the organisation.

Business risk analysis- methodology and risk matrix:

Step 1   IDENTIFY NEEDS AND EXPECTATIONS OF INTERESTED AND AFFECTED PARTIES
Step 2   IDENTIFY POSSIBLE THREATS AND WEAKNESSES
Step 3   IDENTIFY EXISTING CONTROLS
Step 4   EVALUATE CONSEQUENCES
Step 5   EVALUATE PROBABILITIES/FREQUENCY
Step 6   EVALUATE RISK / RISK RATING
Step 7   MITIGATING/OPPORTUNITIES
