Central to our preferred methodology is the Occupational Risk Assessment. Traditional Occupational Health and Safety and Medical Surveillance Programmes are often geared towards merely detecting the presence of (mainly) occupational disease. SDI believes that SHELQ is a preventive discipline, dedicated to reducing the likelihood of adverse events and circumstances that could potentially lead to unnecessary injuries, illness or material losses with your organisation.

We also believe that too little attention is given to the holistic approach that begins with occupational risk assessments and moves towards the implementation of the required changes and programmes designed to minimise future adverse occupational health and safety risks.

Any holistic occupational health and safety programme needs to begin with a thorough Occupational Risk Assessment, which would form the foundation for the strategic design and development of a comprehensive occupational health and safety programme that includes the four essential components of medical surveillance, occupational hygiene audits and monitoring, safety programmes and human resource department liaison, alignment and reconciliation.

This approach is based on the principles of risk and ensures that any programme design is along the lines of ‘risk-based’ theory, thereby deploying financial, human and facility resources appropriately, efficiently and effectively.


SDI’s philosophy is that occupational health risk assessments are key to the systematic examination of the activities and processes in the workplace. Without an occupational risk assessment one would not be able to determine the probability of harmful events, and the extent of the potential damage.
As far as we are concerned, these evaluations enable one to carefully evaluate the degree of exposure of the target groups (or probability of an adverse event), and the consequences (or harmfulness) of this exposure.
These processes and services include but are not necessarily limited to:
      · Workplace Health and Safety risk assessments
      · Walk-through risk assessments
      · Hazardous chemical substance risk assessments
      · Legal compliance audits: to determine the compliance to the requirements of the Occupational Health & Safety Act
      · Occupational Hygiene Surveys
      · Biological Risk Assessments
      · Monitoring Surveys
The outcomes of these workplace health & safety risk assessments will clearly identify the following;
      · The Hazards: what, how harmful, where, how much
      · The Exposures: Quantitative and Qualitative
      · The Risks (combination of Harmfulness and Exposure)
      · The Risk Control action plans ("Corrective Action Report")

SDI produces a comprehensive risk-based analysis report, or GAP Analysis report from the data collected during the occupational health and safety risk assessment, in order to develop the appropriate medical surveillance programme and occupational hygiene audit programme that would best meet and address the gaps identified in the report. This methodology ensures that unnecessary and costly interventions are avoided and focuses the corrective implementation plan on prioritised risk-based initiatives.
