• Apply the appropriate procedure in social distancing

select factors that significant to the environmental impacts during at construction site

• Water pollution

• Noise pollution

• Soil erosion and siltation

• Unorganized storage

Select statements that describe mitigation methods to decrease runoff and flooding at the construction site

• Perimeter channels should be provided at site boundaries to intercept storm water runoff from outside

• Water used in construction site should be recycled back to the site

• Water used in ground boring should as far as practicable be recalculated after sedimentation

• Perimeter channels is not necessarily needed for small area construction site

Select statements describing about applications of sound level meter (SLM) as noise measurement automatic device

• Spot-check noise dosimeter performance

• Aid in determining the feasibility of engineering controls for individual noise sources

• Evaluate hearing protectors

• Identify and evaluate individual noise sources for abatement purposes

select precautions to be taken care using of dosimeter.

• Always check the batteries prior to use. Be very careful with the microphone cable

• Use the microphone windscreen to protect the microphone when the wearer will be outdoors or in dusty or dirty areas.

• Never try to clean a microphone, particularly with compressed air, since damage is likely to result.

• Never share a dosimeter with more than 2 persons per unit in order to get a better result.
