The Legionella Risk Assessment is conducted to enable the risk to be determined and for appropriate measures to be implemented to quantify the risk (via monitoring if necessary) and to reduce or control the risk. The Legionella Risk Assessment is conducted in accordance with SANS 893 (Part 1 and 2). The risk assessment enables management to comply with the Occupational Health and Safety Act, 1993 (Act 85 of 1993) and the Regulations for Hazardous Biological Agents (R 1390 of 2001) and to implement successful environmental health and safety programmes.
