Raw sewage is mainly water containing excrement, industrial effluent and debris and may exist in varying concentrations in flood waters.
Excrement is a major source of harmful micro-organisms, including bacteria, viruses and parasites.
Exposure to sewage or its products may result in a number of illnesses, the majority of these are mild cases of gastro-enteritis characterised by cramping stomach pains, diarrhoea and vomiting. By skin contact, through cuts, scratches or penetrating wounds. Certain organisms can enter the body through the surfaces of the eyes, nose and mouth. Micro organisms can enter the body by breathing dust from dried contamination on personal protective equipment and other equipment. Use safe systems of work and wear the protective equipment that is provided.
