Legionnaires' disease Although the risk of Legionnaires' disease being spread by large-scale water systems cannot be eliminated, it can be greatly reduced by writing and enforcing a highly detailed, systematic water safety plan appropriate for the specific facility involved (office building, hospital, hotel, spa, cruise ship, etc.) Some of the elements that such a plan may include are: An effective water safety plan also covers such matters as training, record-keeping, communication among staff, contingency plans, and management responsibilities. The format and content of the plan may be prescribed by public health laws or regulations. Effective antibiotics include most macrolides, tetracyclines, ketolides, and
Spread Component Spread Component Spread Component (SC) (as used in the National Fire Danger Rating System) is a rating of the forward rate of spread of a headfire. Deeming states that "the spread component is numerically equal to the theoretical ideal rate of spread expressed in feet-per-minute." This carefully worded statement indicates both guidelines (theoretical) and cautions (ideal) that must be used when applying the spread component. Wind speed, slope, and fine fuel moisture are key inputs in the calculations of the spread component, thus accounting for a high variability from day to day. The spread component is expressed on an open-ended
