Scope of application

  1. (1) Subject to the provisions of subregulation (2), these regulations shall apply to every employer and self-employed person at a workplace where -
  1. HBA is deliberately produced, processed, used, handled, stored or transported; or
  2. an incident, for which an indicative list is given in Annexure II, occurs that does not involve a deliberate intention to work with a hazardous biological agent but may result in persons being exposed to a hazardous biological agent in the performance of work.

(2) The provisions of regulations 8, 14, 15, 16 and 17 shall not apply to an employer or self-employed person at a workplace where the exposure is restricted to a Group I HBA.

Classification of biological agents

  1. (1) The chief inspector may publish in the Government Gazette for the purpose of these regulations a document, which may be revised or reissued from time to time, entitled Categorisation of Biological Agents according to hazard and categories of containment" (Annexure V) containing a list of biological agents together with the classification of each agent.

(2) Where a biological agent has not been assigned a classification, the employer and self-employed person shall provisionally classify that agent in accordance with subregulation (3) below, having regard to the nature of the agent and the properties of which he or she may reasonably be expected to be aware.

(3) When provisionally classifying a biological agent the employer and self-employed person shall assign that agent to one of the groups according to its level of risk of infection and, if in doubt as to which of two alternative groups is the most appropriate, the HBA shall be assigned to the higher of the two.

Information and Gaining

  1. (1) Every employer shall, before any employee is exposed or may be exposed, after consultation with the health and safety committee established for that section of the workplace, ensure that the employee is adequately and comprehensively informed and trained, and is thereafter informed and trained at intervals as may be recommended by that health and safety committee with regard to -
  1. the contents and scope of these regulations;
  2. the potential risks to health caused by the exposure;
  3. the measures to be taken by the employer to protect an employee against any risk from exposure;
