According to the Occupational Health and Safety Act No 85 of 1993, Hazardous Biological Agents sub-regulation there is a need for a risk assessment, monitoring and management, and training for all employees on organisms categorised as group 2.  Legionella pneumophila is one such organism and we include Pseudomonas aeruginosa in our assessments as the control measure pertain to both organisms.


Any person who contravenes or fails to comply with any provisions of these regulations shall be guilty of an offence and liable on conviction to a fine or to imprisonment.  It is therefore critical to ensure compliance to the Act and ensuring company policies are aligned at to the regulations as a minimum standard.


The National Standard for Legionella is the SANS 893:1-2: 2018

Our goal is to help the Statutory Duty Holder to be informed and have a clear understanding of his/her legal responsibility.

Know the risk, establish a plan, training

History of Legionnaires Disease

Legionella pneumophila was first identified by the CDC in Atlanta after a number of people contacted pneumonia and some died following an American Legion’s Convention in Philadelphia.  The convention was held at The Bellevue Stratford Hotel.  After months of investigation and research scientist managed to isolate the bacterium and they presumed it was from the cooling tower system at the hotel.


Legionella pneumophila is a bacterium that grows in water systems and cause Legionellosis, which is an umbrella term for all illnesses caused by Legionella bacteria, such as Pontiac Fever, Lochgoilhead Fever and Legionnaires Disease.  Legionnaires’ disease is the most common one and has the highest mortality rate (it kills the most people) of the three.


While the bacteria are commonly found in water at low levels, they can grow to dangerous levels in poorly maintained water systems which create favourable conditions for the bacteria, allowing it to reproduce.


At Accu-AQUA we help facilities managers and business owners to protect their staff and guests by providing them with the tools needed to implement and maintain a safe water system, preventing them from inadvertently causing a Legionnaires disease outbreak.

Hotels and Hospitals

Hotels and Hospitals are subject to the Occupational Health and Safety Act of South Africa along with many other regulations.  This is due to the vulnerable groups make up the majority of the people in hospitals and the lack of knowledge of the health status of the hotel guests.


Hospital water is a high risk since it is involved in a number of different processes such as cooling tower water, water for domestic use, water supply to the autoclaves, kitchen water supply and drinking water.


Hotels may have simpler systems but ultimately have similar problems and requirements. The requirements simply put are as follows:

  • Have a risk assessment of the facility
  • Manage and monitor the water system based on the risk
  • Train up staff on the risks involved for awareness
  • Provide adequate training for staff who manage and mitigate these risks
Assistance and Guidance to Hotels and Hospitals

At Accu-AQUA, we provide assistance and guidance to hotels and hospitals with regards to the water safety management with specific focus on Legionella pneumophila and Pseudomonas aeruginosa.  We can assist your facility with each step required to have a successful water safety management plan if you do not have anything in place yet, we can also assist you with the parts which may be missing or outdated, or we can audit the systems you have in place against the national standard.


The unique service we offer is a collaboration between the relevant service providers and role players of the hotels and hospitals by helping them establish a water safety management team.  This is the approach recommended by many other countries and it is extremely effective since you will include the infection control manager, engineering, water treatment specialists and ourselves. Together these facilities can make educated decisions and take effective action for the water management.
