10. PEDESTAL DRILL A list of authorised users is posted next to the drill and only they can operate the pedestal drill. The Resident Technician will maintain this list. The following points must be adhered to by all users:- The guard must be in position at all times. Eye protection must be worn. Beware of loose clothing. No jewellery or bandages, and gloves must not be worn. Long hair must be tied back. 11. LEGIONELLA CONTROL Legionnaires’ Disease disease [legionellosis] is a form of pneumonia, which is caused Legionnaires’ by inhaling airborne water droplets [aerosols] that are contaminated with bacteria of the Legionella species. There is no evidence to show that the disease can be contracted from someone who is already infected. Legionellosis principally affects those who are susceptible due to age, illness, Immune suppression, smoking etc and can be fatal. Legionella can also cause less serious illnesses which are not fatal or permanently debilitating but which can affect any person. Legionella is commonly found in water systems. However the issue of concern is the avoidance of the conditions necessary for the growth and proliferation of the organism. These include:- Dirty water systems the presence of sludge, scale, rust, algae and – organic matter; Water temperatures in the range 20 to 45C Legionella multiplies – within this range. It is killed rapidly at water temperatures above 60C. Below 20C it stays dormant but will grow if the temperature is raised and other conditions are favourable. Prevention The fluid tanks and systems used in and around the laboratory are used for experiments and use a large volume of water which in some cases may sit stagnant for prolonged periods or are dosed or treated with chemicals etc for the purposes of the experiments being carried out. It is generally accepted in the water hygiene industry, that when faced with assessing the risks associated with Legionellosis froma system such as that found in the Fluids Lab, 3 questions must be asked of that system: Is the water dirty/stagnant/potentially contaminated?
