ABSTRACT
Noise pollution can be defined as the unwanted sound that is released to the environment and disturbing the human beings. Sources of noise pollution include industrial sources, non-industrial sources, vehicles, uncontrolled use of loud speakers, construction activities such as drilling, etc. Noise levels from vehicles through engines and horns are the main cause of concern in cities and may potentially contribute about 60% of total noise pollution. An attempt was made to measure noise levels emanating from vehicles on selected roads within a radius of approximately two kilometers from St Joseph’s College. These are major roads that witness heavy traffic during peak and non-peak hours. Traffic volume and noise levels were measured at various junctions on these roads during peak and non-peak hours. The study also includes remedial measures that can be implemented to reduce the noise levels.

Both are considered acceptable for fall protection so long as they meet the general requirements and the performance criteria specified for their type. General requirements for all fall arrest anchorages include:
i. Located as high as possible to minimize the free fall distance to and arresting forces to < 1800 pounds. (8kN).

ii. Located to prevent contact with obstructions or the ground below.

iii. Located directly over the working position whenever possible to minimize swing falls.
