attendants and sanitation staff had mean scores o f 58.7, 66.9, 65.1, 78.2, 68.9 respectively on knowledge and mean
scores o f 62.0, 68.5, 65.7, 77.0 and 76.2 respectively on practices out of a total score of 100. A statistically
significant relationship was observed between knowledge and practices (p<0.01) and attendance of training
programmes with knowledge (p< 0.001) & practices (p< 0.01) on BMW management. Deficiencies in facilities for
